Hi,
Maybe it is a nice enhancement for make menuconfig to more explicitly
give a pop-up or so when someone selects for example a sata controller
while no 'scsi-disk' support was selected?

Having no sd support is perfectly valid. Imagine a diskless boot
with only sr support.

Ok, but that's not the most common situaties. What I'm suggesting is a
warning or a please note popup. Not neccessarily an error or refusing to
continue thing.

I know that it's difficult to get people to read docs & help text,
and maybe it is needed in more places, but CONFIG_ATA (SATA/PATA)
help text says:
NOTE: ATA enables basic SCSI support; *however*,
'SCSI disk support', 'SCSI tape support', or
'SCSI CDROM support' may also be needed,
depending on your hardware configuration.
A popup makes some sense, but I don't know if menuconfig knows how to
do popup warnings... and it needs to be done for all *configs,
not just menuconfig.

Yes but that would mean that you have to open the help for each item
that you add.

Maybe add a new type?

What IMHO makes sense is changing all references to SCSI CDROM,
SCSI DISK etc. to just CDROM, DISK, and changing SCSI (menu) to
something like MASS STORAGE.

There is still too much SCSI in it IMO :-)

Yes! Maybe create some status-line at the bottom of the screen in which
these hints scrollby. Like powertop does.

I once sent a patch to make libata a submenu of scsi.
[PATCH] libata Kconfig: Allow libata to be selected from within the SCSI submenu
From: Al Boldi <[email protected]>
To: [email protected]
CC: Alan Cox <[email protected]>, [email protected]
Date: 08/01/07 07:22 am
Move libata Kconfig sourcing from the drivers Kconfig into the SCSI Kconfig.
This allows the user to quickly select additional disk/tape/cdrom support
from within the same menu.

'comment' is already supported by make {menu,x,g}config and AFAIK by
make oldconfig too. It is not effective in make oldconfig though
because it will scroll off the screen quickly.
I am not a friend of 'select', but maybe the following actually helps.
I didn't follow all of this and previous related discussions, so I guess
somebody else suggested something like this before:
# drivers/ata/Kconfig
config ATA
[...]
comment "Controller drivers"
[...low-level drivers go here...]
comment "Storage device drivers"
config ATA_SD
tristate "SATA/PATA HDD support (via SCSI disk support)"
depends on ATA
select BLK_DEV_SD
help
'SCSI disk support' is required to access SATA HDDs. It is
also necessary for parallel ATA (IDE) HDDs if you use the
experimental parallel ATA option.
You can say Y or M here to select SCSI disk support, or you
can do so in the 'SCSI device support' section.
[...ditto for CD/DVD-ROMs, tapes, and generic support...]

And to explain that point: SCSI device name inquiry is limited to 16 bytes.
That may be a limitation of SCSI (as in: the protocol), but the SCSI
*subsystem* should not impose such a tight limit.

And what uses ATA_SD, or is the user supposed to manually enable it?

It is merely there to produce the prompt which people asked for.
CONFIG_ATA_SD (or CONFIG_ATA_BLK_DEV_SD or whatever) won't turn up in
any Makefile or source code.
Note, I'm not fond of 'select' nor of dummy Kconfig variables. Plus I
can personally live very well with the current solution (sd_mod et al
are mentioned in the help text at CONFIG_ATA). That's why I posted only
the example instead of a complete patch.

For menuconfig I would much rather see that it had an additional
window at the bottom displaying the help text for the active menu line.
Implementing support for a pop-up in the kconfig language seems to be a bit
off the purpose of the kconfig language.

Which is wrong
Nakked-by: Alan Cox <[email protected]>
The general comments about moving this stuff around and making it clearer
what sd/sr etc are nowdays are good but hiding libata under SCSI will
cause even more confusion than it cures

That's easy to fix: just change the SCSI heading to include a libata hint.
Something like this:
[PATCH] libata Kconfig: Allow libata to be selected from within the SCSI submenu
Move libata Kconfig sourcing from the drivers Kconfig into the SCSI Kconfig,
and change the SCSI menu heading to indicate libata submenu inclusion.
This allows the user to quickly select additional disk/tape/cdrom support
from within the same menu.

This has also bitten me one or two times. A reasonable way would
be to just select SD automatically for !EMBEDDED

The problem with 'select' here is that it will enable BLK_DEV_SD,
but if SCSI is not enabled, it will not become enabled -- i.e.,
select does not follow the dependency chain. So usually the
kernel will not build unless SCSI is enabled by the user.

I checked the dependencies. ATA depends on SCSI (actually, selects
SCSI), so all is well. Otherwise I would have added more dependencies
to ATA_SD.

I think you're fixing the wrong problem.
The real problem is hiding devices attached to some controlers between
one kind of the controllers. This has been correct whern they were bus-
specific, but since they are now shared by three busses, they should get
their own menu called "(S)ATA/USB/SCSI attached devices" - or whatever a
native speaker would suggest.
Besides that, if I imagine being a semi-novice and searching for IDE
support, I would have a hard time finding the IDE menu, and asuming
PATA to be non-experimental one day, I'd have a hard time deciding
which of the drivers to use. Maybe the SATA-drivers should be put
above the old PATA menu, amd maybe both of the titles should include
"(E)IDE"?
BTW: For CONFIG_ATA, you can replace
"(!M32R && !M68K || BROKEN) && (!SUN4 || BROKEN)"
with "(!M32R && !M68K && !SUN4 || BROKEN)"
BTW2: I think that menu needs very much reordering. "Block devices" should
be renamed to "Other block devices", AGP support should belong into graphics
support, and many other things I don't even know need to be pushed around.
Even ordering by name would be better than the current situation! But it
should be done by someone knowing these devices, I could only do a part.

That's not entirely fair ... if you're switching over from a config
you've been dragging around for years which uses IDE rather than ATA,
it's far from obvious which config options you need to change. I think
Andi's patch is a good one. It might also be good to select SR (at
least my wife's laptop has the cd-rom on SATA).

Vendor kernels tend to compile forever and require initrds. For
just testing a kernel quickly compiling only a few drivers in
is much more convenient.
Also when you've been using CONFIG_IDE before it is not completely
obvious you need BLK_SD for your hard disk.

A side note: SCSI is not a bus. It is an architecture and a set of
implementation standards; including command set standards, transport
protocol standards and interconnect standards for a whole lot of
different applications, transports, and interconnects, and not all of
the latter are actual buses. The oldest of SCSI interconnects, SCSI
Parallel Interconnect alias SPI, is often mistaken for all of SCSI even
though its role is diminishing. There is much more:
http://www.t10.org/scsi-3.htm
You are right though that Linux' SCSI command set drivers and SCSI core
are used for non-SCSI transports too, and this is not very well
reflected by the configuration menu layout. (But is there an ideal menu
layout? I'm sure there isn't.)

The individual driver descriptions don't say BLK_SD needs to be selected.
Besides if all descriptions said that the computer could as well
do it for the user automatically. After all it's a stupid repetive
task and computers are much better at those than humans.

At least the help to CONFIG_ATA says so.

In your patch, it is not the computer who finds out that the user wants
BLK_SD. It is you who predetermined that the user wants it.

Not completely though. Whenever a 'select' is inserted into the
dependency graph, the whole thing becomes more fragile WRT future changes.

Actually, this should have read:

I would think that with this minimal change it would make it crystal clear,

I can see where you're coming from, but logically, this is wrong.
There's a huge slew of enterprise machines that only have DVD on SATA.
On the other hand, all of these machines will have SCSI disk devices on
various other transports, so no harm is done, it's just an inelegant
solution.

Let's step back a moment and consider the actual scale and impact of the
problem at hand.
The vast majority of users are consumers of pre-compiled kernels, built
by People With Clue(tm), who figured this stuff out as soon as it was
introduced.
The current setup expresses the dependencies as they exist -- OPTIONAL
extras, and that is a problem once a year or so, when someone builds
their own kernel but must learn this fact anew.
There is simply no compelling need at all to change things from the
current setup.
Our Kconfig system is for people who already know the kernel, not Aunt
Tillie.

Disk support over SCSI/SATA is hardly an "optional extra". It's more the 99+%
case.

When it costs 10000 people half an hour to learn and correct this it
wasted 5000 hours of previous livetime.
Besides there is no good reason to have ever learned this imho.

Using that argument, there's an equal case for always requiring SCSI to
be built for every kernel, since very few people can boot a system
without a disk. However, the 1% case is the embedded flash booting
community plus a few others, so we allow SCSI to be optional for our 1%
who don't want it.
At base, the Kconfig system is designed to give the greatest flexibility
with the fewest foot shooting opportunities. However, we do tend to err
on the side of flexibility if there's a conflict between the two design
goals.

The process of becoming an expert in the kernel build system naturally
involves making mistakes and learning from them, so this is probably
time reasonably well spent.

Nevertheless we should try to arrange the menus in a way that makes
sense to as many people as possible. The difficulty is, different
environments call for different menu layouts, as your previous example
of SATA DVD-only boxes demonstrates.
However, liberal usage of 'select' is not the ultimate solution to
create menus that work for more people. Just one problem with select is
that it works behind the back of the people configuring kernels (unless
they use an UI with debug options turned on) --- they have less control,
they are less informed. ATA already 'select's SCSI. What do we gain
from hiding the fact that Linux' SCSI option is not just for those
50-wire ribbons (which people still think SCSI stands for) but is a very
central Linux subsystem for even more than what complies to the SCSI
family of standards?
'select' should really be limited to switch on small library-like code
without further dependencies or requirements. SCSI, together with its
upper layer options, is not of this kind of library.
We should think about order and grouping of prompts and the labels of
prompts (there were already suggestions in this discussion) before we
resort to 'select' --- or even worse, select options unconditionally
which are not always necessary to be enabled.
A pro pos grouping of options --- consider how options for another
central subsystem are laid out:
Networking
Networking options
...
TCP/IP networking
...
...
Device Drivers
...
Network device support
...
Ethernet (10 or 100MBit)
...
...
This also happens to reflect the layout of sources in directories, and
the current SCSI menu layout is close to source layout too --- but it
doesn't have to be that way.

If someone's keen on really restructuring these things -- in this analogy:
Storage
Storage Options
...
Disk
Optical
...
...
Device Drivers
...
Storage Support
...
IDE
PATA
SATA
SCSI
USB
FW
...
...
(sound is an example where both in the menus and the tree everything is kept
under one top-level sound/ directory, not sound/ and drivers/sound/ as for
networking -- opinions may vary which one's better I guess).
This is just config menus -- on a source code level, it would also make
sense at least at some point to introduce "storage/" alongside net/ and
sound/ and move things around I guess.

Couldn't we just remove kconfig and assume that all "people who already
know the kernel" anyway prefer to edit their .config using vi? ;-)
In my experience, the vast majority of kconfig users are not the few
people working on distribution kernels, most of the kconfig userbase
could be better described by the use case "sysadmin who knows about the
hardware in his machine and which filesystems he uses".
And there must have been a reason why a leading kernel developer has
written a complete book covering only configuration and building of the
kernel - the target audience of this book are most likely not "people
who already know the kernel".

A popup hardly ever makes sense - popups generally are a
bad user interface. The user will have to dismiss the popup -
every time - whether he needs the warning or not.
But feel free to print a warning somewhere, such as a
status line. The warning itself is useful, but not something
we will have to dismiss in order to go on with the job.

The patch which is discussed here is specifically targeted towards users
who are convinced that they can migrate to different drivers without
reading Kconfig help texts.

Nothing about the patch is only about migration.
The same applies if you configure a kernel from scratch.
Do "make menuconfig" with the .config you are normally using, count the
number of options that are visible, and ask yourself whether we can
really expect users to read the help texts for every single option shown.
People mostly read help texts for options where they don't understand
what this option is about - and "Serial ATA" therefore is an option that
is likely to get enabled without the user looking at the help text.

If you create .config from scratch, then you can get away without
reading help texts if you have a target with minimal hardware and
protocols requirements and you know all the subsystems involved.
In all other cases, you theoretically need to read all help texts (minus
the ones that don't appear because you deselect entire subsystems). In
practice, this takes too much time, hence you take an existing .config
(yours or somebody else's) and go from there.
Whenever one enables an option for the first time, it would IMO be
foolish to ignore its help text.

Kconfig let's you start with the defconfig when doing "make menuconfig"
without any .config present, so in practice users start from the
defconfig and then go through all menus at once enabling and disabling
options to adapt the configurations to their needs.
Or they start from the "includes everything" .config of their
distribution and remove everything they don't need.

Then the number of non-foolish users is quite near to 0...
If you expect people to read several hundreds or thousands of help texts
only for configuring a kernel then you are expecting something that is
simply not realistic.
It is intuitive for a user to enable the "Serial ATA" menu and he might
not expect to have to read the help text when he has SATA drivers, while
having to enable anything in the "SCSI device support" menu is highly
unintuitively when the user does not have SCSI hardware.

Could one duplicate the configure options for scsi disk/tape/cdrom at
that place? The text should then probably read SCSI/SATA disk support
in both places.

Perhaps. Although I meant only options which one enables oneself, not
options which are taken over from somebody else's .config.

It surely is unintuitive, and it is one of the worse cases where the
current menu layout is unintuitive. We have to improve that, even
though it is ultimately impossible to serve everyone's needs equally
well or, generally, make kernel configuration a piece of cake.
Note though, some suggestions which came up here don't actually make the
menus more intuitive. Notably the patch "Select BLK_DEV_SD for all
SCSI/libata drivers" is counterintuitive in a different color: It
follows the philosophy of "I know what's good for you and I act on your
behalf behind your back --- trust me, it's for your best".
I too am guilty of proposing the usage of 'select'
(http://lkml.org/lkml/2007/9/8/9) but I suggested a variant which lets
the user stay informed and in control (as far as this is possible with
'select' which always increases complexity, never reduces it).
But rather than adding multiple menu items which enable the same option,
a reorganization of the menus which better reflect the role of SCSI core
and SCSI highlevel might be more effective --- similar to "Networking"
which is separate from "Network device support"
(http://lkml.org/lkml/2007/9/10/5, http://lkml.org/lkml/2007/9/10/115).

The SCSI core and SCSI high-level drivers play a central role not just
for the whole lot of different SCSI Architecture types of hardware and
protocols, but also for subsystems which drive non SCSI hardware,
especially libata.
Hence the options pertaining to SCSI core and high-level are separated
out into an own top-level menu outside the "Device Drivers" submenu, and
some prompts are reworded.

core's widespread usage", http://lkml.org/lkml/2007/9/14/168. These two

- help
- WARNING This driver is an older aic7xxx driver and is no longer
- under active development. Adaptec, Inc. is writing a new driver to
- take the place of this one, and it is recommended that whenever
- possible, people should use the new Adaptec written driver instead
- of this one. This driver will eventually be phased out entirely.
-
- This is support for the various aic7xxx based Adaptec SCSI
- controllers. These include the 274x EISA cards; 284x VLB cards;
- 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
- motherboard based SCSI controllers from Adaptec. It does not support
- the AAA-13x RAID controllers from Adaptec, nor will it likely ever
- support them. It does not support the 2920 cards from Adaptec that
- use the Future Domain SCSI controller chip. For those cards, you
- need the "Future Domain 16xx SCSI support" driver.
-
- In general, if the controller is based on an Adaptec SCSI controller
- chip from the aic777x series or the aic78xx series, this driver
- should work. The only exception is the 7810 which is specifically
- not supported (that's the RAID controller chip on the AAA-13x
- cards).
-
- Note that the AHA2920 SCSI host adapter is *not* supported by this
- driver; choose "Future Domain 16xx SCSI support" instead if you have
- one of those.
-
- Information on the configuration options for this controller can be
- found by checking the help file for each of the available
- configuration options. You should read
- <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
- contacting the maintainer with any questions. The SCSI-HOWTO,
- available from <http://www.tldp.org/docs.html#howto>, can also

- adapters are still today everywhere placed as SCSI-id 7 by default.
- In the SCSI-standard, the drive letters express the priority of the

- highest priority. This must therefore be the disk with the highest

- "Tagged command queuing" is a feature of SCSI-2 which improves

- device's queue even if previous commands haven't finished yet.
- Because the device is intelligent, it can optimize its operations
- (like head positioning) based on its own request queue. Some SCSI
- devices don't implement this properly; if you want to disable this
- feature, enter 0 or 1 here (it doesn't matter which).
-
- The default value is 8 and should be supported by most hard disks.
- This value can be overridden from the boot command line using the
- 'tags' option as follows (example):
- 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
- 4, set queue depth to 16 for target 2 and target 3 on controller 0
- and set queue depth to 10 for target 0 / lun 2 on controller 1.
-

- a boot command line option for devices that need to use a different
- command queue depth.

- Modern hard disks are able to support 64 tags and even more, but

-config SCSI_NCR53C8XX_SYNC
- int "synchronous transfers frequency in MHz"
- depends on SCSI_ZALON || SCSI_NCR_Q720
- default "20"
- ---help---
- The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
- rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
- are respectively the maximum data transfer rates in mega-transfers
- per second for each class. For example, a FAST-20 Wide 16 device is
- able to transfer data at 20 million 16 bit packets per second for a
- total rate of 40 MB/s.
-
- You may specify 0 if you want to only use asynchronous data
- transfers. This is the safest and slowest option. Otherwise, specify
- a value between 5 and 80, depending on the capability of your SCSI
- controller. The higher the number, the faster the data transfer.
- Note that 80 should normally be ok since the driver decreases the
- value automatically according to the controller's capabilities.
-
- Your answer to this question is ignored for controllers with NVRAM,
- since the driver will get this information from the user set-up. It
- also can be overridden using a boot setup option, as follows
- (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
- for FAST-20 synchronous data transfer (20 mega-transfers per
- second).
-
- The normal answer therefore is not to go with the default but to
- select the maximum value 80 allowing the driver to use the maximum
- value supported by each controller. If this causes problems with
- your SCSI devices, you should come back and decrease the value.
-
- There is no safe option other than using good cabling, right
- terminations and SCSI conformant devices.

+ The SCSI-standard follows a hardware-hierarchy which says that id 7
+ has the highest priority and id 0 the lowest. Therefore, the host
+ adapters are still today everywhere placed as SCSI-id 7 by default.
+ In the SCSI-standard, the drive letters express the priority of the

+ "Tagged command queuing" is a feature of SCSI-2 which improves
+ performance: the host adapter can send several SCSI commands to a
+ device's queue even if previous commands haven't finished yet.
+ Because the device is intelligent, it can optimize its operations
+ (like head positioning) based on its own request queue. Some SCSI
+ devices don't implement this properly; if you want to disable this
+ feature, enter 0 or 1 here (it doesn't matter which).
+
+ The default value is 8 and should be supported by most hard disks.
+ This value can be overridden from the boot command line using the
+ 'tags' option as follows (example):
+ 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
+ 4, set queue depth to 16 for target 2 and target 3 on controller 0
+ and set queue depth to 10 for target 0 / lun 2 on controller 1.
+
+ The normal answer therefore is to go with the default 8 and to use
+ a boot command line option for devices that need to use a different
+ command queue depth.
+
+ There is no safe option other than using good SCSI devices.
+
+config SCSI_NCR53C8XX_MAX_TAGS

+ Modern hard disks are able to support 64 tags and even more, but
+ do not seem to be faster when more than 32 tags are being used.
+
+ So, the normal answer here is to go with the default value 32 unless

+ rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers

+ per second for each class. For example, a FAST-20 Wide 16 device is
+ able to transfer data at 20 million 16 bit packets per second for a
+ total rate of 40 MB/s.
+
+ You may specify 0 if you want to only use asynchronous data
+ transfers. This is the safest and slowest option. Otherwise, specify
+ a value between 5 and 80, depending on the capability of your SCSI
+ controller. The higher the number, the faster the data transfer.
+ Note that 80 should normally be ok since the driver decreases the
+ value automatically according to the controller's capabilities.
+
+ Your answer to this question is ignored for controllers with NVRAM,
+ since the driver will get this information from the user set-up. It
+ also can be overridden using a boot setup option, as follows
+ (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
+ for FAST-20 synchronous data transfer (20 mega-transfers per
+ second).
+
+ The normal answer therefore is not to go with the default but to
+ select the maximum value 80 allowing the driver to use the maximum

You left out PATA running libata drivers. Not just SATA is affected

Exactly the same change for all architectures.
IT would be good to introduce a common file that contains
some of the shared stuff from the different architectures.
We could start out simple with:
arch/Kconfig.arch:
source "net/Kconfig"
source "drivers/Kconfig"
source "fs/Kconfig"
source "security/Kconfig"
source "crypto/Kconfig"
source "lib/Kconfig"
And then source it in all relevant arch Kconfig files.
It is not all that can use it but most do.
A trivial task but one small step towards unification between
the architectures on the Kconfig level.

Subject: SCSI: split Kconfig menu into two
The SCSI core and SCSI high-level drivers play a central role not just
for the whole lot of different SCSI Architecture types of hardware and
protocols, but also for subsystems which drive non SCSI hardware,
especially libata.
Hence the options pertaining to SCSI core and high-level are separated
out into an own top-level menu outside the "Device Drivers" submenu, and
some prompts are reworded.

- ---help---
- In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks

- (physical number -- pun) to be drive C:, as seen from DOS and
- similar operating systems. When looking into papers describing the
- ANSI-SCSI-standard, this assignment of drives appears to be wrong.
- The SCSI-standard follows a hardware-hierarchy which says that id 7
- has the highest priority and id 0 the lowest. Therefore, the host
- adapters are still today everywhere placed as SCSI-id 7 by default.
- In the SCSI-standard, the drive letters express the priority of the
- disk. C: should be the hard disk, or a partition on it, with the
- highest priority. This must therefore be the disk with the highest
- SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
- original definition of the SCSI-standard as also industrial- and
- process-control-machines, like VME-CPUs running under realtime-OSes
- (e.g. LynxOS, OS9) do.
-
- If you like to run Linux on your MCA-machine with the same
- assignment of hard disks as seen from e.g. DOS or OS/2 on your

- must say Y here. This is also necessary for MCA-Linux users who want
- to keep downward compatibility to older releases of the
- IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
- June 1997).
-
- If you like to have the lowest SCSI-id assigned as drive C:, as

- here. If unsure, say Y.

- int "default tagged command queue depth"

- ---help---
- "Tagged command queuing" is a feature of SCSI-2 which improves
- performance: the host adapter can send several SCSI commands to a
- device's queue even if previous commands haven't finished yet.
- Because the device is intelligent, it can optimize its operations
- (like head positioning) based on its own request queue. Some SCSI
- devices don't implement this properly; if you want to disable this
- feature, enter 0 or 1 here (it doesn't matter which).
-
- The default value is 8 and should be supported by most hard disks.
- This value can be overridden from the boot command line using the
- 'tags' option as follows (example):
- 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
- 4, set queue depth to 16 for target 2 and target 3 on controller 0
- and set queue depth to 10 for target 0 / lun 2 on controller 1.
-
- The normal answer therefore is to go with the default 8 and to use
- a boot command line option for devices that need to use a different
- command queue depth.
-
- There is no safe option other than using good SCSI devices.

- Modern hard disks are able to support 64 tags and even more, but
- do not seem to be faster when more than 32 tags are being used.
-
- So, the normal answer here is to go with the default value 32 unless

- are able to take advantage of more than 32 tagged commands.

- There is no safe option and the default answer is recommended.

- rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers

- per second for each class. For example, a FAST-20 Wide 16 device is
- able to transfer data at 20 million 16 bit packets per second for a
- total rate of 40 MB/s.
-
- You may specify 0 if you want to only use asynchronous data
- transfers. This is the safest and slowest option. Otherwise, specify
- a value between 5 and 80, depending on the capability of your SCSI
- controller. The higher the number, the faster the data transfer.
- Note that 80 should normally be ok since the driver decreases the
- value automatically according to the controller's capabilities.
-
- Your answer to this question is ignored for controllers with NVRAM,
- since the driver will get this information from the user set-up. It
- also can be overridden using a boot setup option, as follows
- (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
- for FAST-20 synchronous data transfer (20 mega-transfers per
- second).
-
- The normal answer therefore is not to go with the default but to
- select the maximum value 80 allowing the driver to use the maximum
- value supported by each controller. If this causes problems with
- your SCSI devices, you should come back and decrease the value.
-

How about that one for libata driven PATA CDROM drives? Could replace
SATA with libata, or something similar.

Actually the addition "This menu also presents options for specific SCSI
controllers..." from that patch is then no longer true.

(I'll gladly do that, or only send an update of the 'split Kconfig menu'
patch with that sentence backed out, if desired.)

Subject: SCSI: split Kconfig menu into two
The SCSI core and SCSI high-level drivers play a central role not just
for the whole lot of different SCSI Architecture types of hardware and
protocols, but also for subsystems which drive non SCSI hardware,
especially libata.
Hence the options pertaining to SCSI core and high-level are separated
out into an own top-level menu outside the "Device Drivers" submenu, and
some prompts are reworded.

- In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks

- (physical number -- pun) to be drive C:, as seen from DOS and
- similar operating systems. When looking into papers describing the
- ANSI-SCSI-standard, this assignment of drives appears to be wrong.
- The SCSI-standard follows a hardware-hierarchy which says that id 7
- has the highest priority and id 0 the lowest. Therefore, the host
- adapters are still today everywhere placed as SCSI-id 7 by default.
- In the SCSI-standard, the drive letters express the priority of the
- disk. C: should be the hard disk, or a partition on it, with the
- highest priority. This must therefore be the disk with the highest
- SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
- original definition of the SCSI-standard as also industrial- and
- process-control-machines, like VME-CPUs running under realtime-OSes

- int "default tagged command queue depth"

- ---help---
- "Tagged command queuing" is a feature of SCSI-2 which improves
- performance: the host adapter can send several SCSI commands to a
- device's queue even if previous commands haven't finished yet.
- Because the device is intelligent, it can optimize its operations
- (like head positioning) based on its own request queue. Some SCSI
- devices don't implement this properly; if you want to disable this
- feature, enter 0 or 1 here (it doesn't matter which).
-
- The default value is 8 and should be supported by most hard disks.
- This value can be overridden from the boot command line using the
- 'tags' option as follows (example):
- 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
- 4, set queue depth to 16 for target 2 and target 3 on controller 0
- and set queue depth to 10 for target 0 / lun 2 on controller 1.
-
- The normal answer therefore is to go with the default 8 and to use
- a boot command line option for devices that need to use a different
- command queue depth.
-
- There is no safe option other than using good SCSI devices.

- Modern hard disks are able to support 64 tags and even more, but
- do not seem to be faster when more than 32 tags are being used.
-
- So, the normal answer here is to go with the default value 32 unless

- rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers

- per second for each class. For example, a FAST-20 Wide 16 device is
- able to transfer data at 20 million 16 bit packets per second for a
- total rate of 40 MB/s.
-
- You may specify 0 if you want to only use asynchronous data
- transfers. This is the safest and slowest option. Otherwise, specify
- a value between 5 and 80, depending on the capability of your SCSI
- controller. The higher the number, the faster the data transfer.
- Note that 80 should normally be ok since the driver decreases the
- value automatically according to the controller's capabilities.
-
- Your answer to this question is ignored for controllers with NVRAM,
- since the driver will get this information from the user set-up. It
- also can be overridden using a boot setup option, as follows
- (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
- for FAST-20 synchronous data transfer (20 mega-transfers per
- second).
-
- The normal answer therefore is not to go with the default but to
- select the maximum value 80 allowing the driver to use the maximum
- value supported by each controller. If this causes problems with
- your SCSI devices, you should come back and decrease the value.
-

+

+ controller. The higher the number, the faster the data transfer.
+ Note that 80 should normally be ok since the driver decreases the

I think I'll rewrite it as "for newer SCSI transports such as FireWire
storage." ;-)
If SRP was in, can 'such as' be omitted? "for newer SCSI transports
(Fibre Channel, FireWire storage, iSCSI, SAS, SRP)," Or would be "for
newer SCSI transports such as Fibre Channel, FireWire storage, iSCSI,
SAS, and more," be OK?

As a "make menuconfig" user, let me say that I agree. Of course, I'm used
to rebuild kernel, but sometimes, some options are not clear, and the help
text is searched for. But, getting too much of "No help text available"
usually results in people no more reading the help text.
What about splitting the screen to have the top half with the menu, and the
bottom half with the help ?

I assert that a Kconfig prompt (a visible Kconfig variable) _without_

It might be necessary to add SSA too.

scsi-ml has SPI, FC, iSCSI, SAS, and SRP transport classes (SRP is in
scsi-misc now). It's a bit strange to omit only SRP, I think. But I
might be too SRP-biased.

Nearly right. ;-)
There are a few architectures not (yet) using drivers/Kconfig.

This way the order is wrong:
There should first be the lowlevel SCSI, SATA, USB etc. drivers, these
drivers should select CONFIG_SCSI, and then the menu offering support
for disk, CD,...

What is "storage support"?
SATA?
PATA?
USB mass storage?
MMC?
MTD?
Whether or not a driver uses the SCSI layer is an implementation detail
(it even differs for the two USB mass storage implementations and the
two PATA implementations in the kernel) the user shouldn't have to know
about.
I don't see any reason why CONFIG_SCSI should have to stay user-visible
at all after your patch.

Right, the patch is wrong for those architectures which include
drivers/scsi/Kconfig directly, rather than indirectly via drivers/Kconfig.

The order was inspired by
# the protocols etc.
"Networking"
# the interconnects
"Device Drivers"/ "Network device support"
So that order is wrong too?
However, there is also precedence for the order which you suggest: The
partition and filesystems options come after device driver options.

Vice versa, I don't see any reason for "select SCSI" anywhere after my

"such as... and more" suggests that there are indeed more SCSI
transports supported by Linux than mentioned in this help text.
We could also write "such as Fibre Channel, iSCSI, SAS, and more," if
you suspect bias on my side. ;-) Help texts should be concise.

It's different since _all_ network device drivers require networking
support.

Different to CONFIG_SCSI, CONFIG_NET=n is so exotic that we should
change it to no longer show users the question unless CONFIG_EMBEDDED=y.

If users who don't need it now enable CONFIG_SCSI (and drivers/ide/
usage is not that uncommon) that's a regression in the user interface.
If the lowlevel SCSI drivers move into a separate menu as your patch
does, we simply no longer have any good reason for bothering the user
with the CONFIG_SCSI.

I think that you can remove "such as" if you add SRP and SSA. "for
SCSI transports such as Fibre Channel, FireWire, SAS, iSCSI, SRP, or
SSA" should be fine. But I'm not sure that scsi-ml has a SSA hba
driver. If not, we could remove SSA.

Aha, first all interconnects/transports are configured. If none of them
'select'ed SCSI, the menu for sd, sr, st stays invisible. Otherwise it
is exposed.
It still doesn't entirely clarify whether users need sd, sr, st, and
whether thy need sd for the disk with root filesystem.

Maybe you can hide CONFIG_SCSI, but you still need to provide the above
information --- then under the sd, sr, st, sg options, which may
actually be the better places although it increases redundancy.

If you want to do it in a really perfect way, help texts aren't the
solution. You'll have to make the options like CONFIG_BLK_DEV_SR no
longer be user visible and select'ed through dummy options like e.g.:
config USB_STORAGE
tristate "USB Mass Storage support"
depends on USB
select SCSI
help
...
config USB_STORAGE_SD
tristate "USB Mass Storage hard disk support"
depends on USB_STORAGE
select BLK_DEV_SD
help
...
config USB_STORAGE_SR
tristate "USB Mass Storage CD/DVD support"
depends on USB_STORAGE
select BLK_DEV_SR
help
...

Perfect is in the eye of the beholder. You would consequently have to
add such options into all menus which contain scsi low-level providers.
Also, one more question on whether CONFIG_SCSI ought to be 'select'ed:
Where do scsi-core options like CONFIG_SCSI_CONSTANTS go?

Kconfig is a user interface, so perfect is what is best for the
kconfig users.
> Also, one more question on whether CONFIG_SCSI ought to be 'select'ed:
> Where do scsi-core options like CONFIG_SCSI_CONSTANTS go?
The first question is whether it's for actual SCSI hardware [1] or for
the block layer functionality which the SCSI subsystem has become.
The mixture of these two is the root of much user confusion.
With the help text "The error messages regarding your SCSI hardware will
be easier to understand if you say Y here" a user wouldn't have expected
to see you using it in a firewire driver. But unless I miss anything,
the setting of SCSI_SCAN_ASYNC does only affect "real" SCSI hardware.
If you check each option and place it either in the generic storage menu
or the SCSI lowlevel menu this would fix much possible user confusion.
But these are relatively unimportant options compared to e.g.
USB_STORAGE=y, BLK_DEV_SD=n, which is a misconfiguration many
users run into, so having one menu somewhere with these advanced
options should be enough.

Duplicate options with different names in different menus, but which all
do the same, --- is this the best for users?

FireWire hardware which implements SBP-2 is SCSI hardware... But this
detail aside --- yes, of course this help text is old and misleading.
> But unless I miss anything,

It affects every hardware which is driven by scsi low-level providers
which have been integrated with the SCSI_SCAN_ASYNC facility.

True.
So,
config SCSI_CONSTANTS
"Kernel log messages from the SCSI subsystem will be easier to
understand if you say Y here..."
would say what this option really does. But to some degree the need to
explain what the SCSI subsystem or SCSI core is and which other
subsystems make use of it remains. Maybe it's OK to provide
documentation of this kind outside of Kconfig help though.
> [1] SCSI as in "sold as SCSI"
Difficult. Does e.g. hardware sold as SAS count as "sold as SCSI"? How
about SBP-2 then? ;-)

I recognize it's a rhetorical question :) The answer is of course "no".
I hope the other participants of this thread register the severe
disinclination of the maintainers to change this stuff, as this is a
classic case of making a mountain out of a molehill[1].
For the -vast majority- of people configuring the kernel, this is not a
problem. Kernel people are -expected- to know what they're doing,
especially when switching from one major subsystem to another.
Therefore, all this is IMO wasted effort and hot air. There are far
more important issues to deal with.

The same prompt existed in arch/i386/Kconfig without help text too but
it was later made invisible and automatic by pre-2.6.13 patch "remove
special HPET_EMULATE_RTC config option", commit
c91096d85c95c6b7fe8d7065e2aa6825e0bdaca9: "We had a user whose apps
weren't working correctly because his "rtc" wasn't working fully. For
the sake of simplicity, it seems sensible to always enable HPET RTC
emulation."
- So, which criteria influence whether HPET_EMULATE_RTC should be
enabled on x86_64 or not?
- In case that there is no compelling reason to disable it if its
dependencies are satisfied, shouldn't it rather be invisible and
automatic like on i386?

I doubt your claim is true since the vast majority of kconfig users
are most likely not kernel developers.

Why don't we dump kconfig and write the .config by hand? ;-)
More seriously:
Yes, there are many other important issues in the kernel.
But not fixing kconfig UI problems doesn't fix these issues faster.
I have seen people running into problems because some required
option wasn't set - in the simplest cases things like IDE without DMA
because a help text wasn't updated when more hardware support was added
to a driver.
You might not care about the kconfig users.
But other people do.

Different to your approach of trying to achieve the same with one huge
help text I see a realistic chance of it working.
What's other alternatives do we have?
Automatically select BLK_DEV_SD and BLK_DEV_SR if one driver that uses
the SCSI layer gets enabled by the user?

This is a debug option and it's unlikely that users will need it unless
someone explicitely requested them to do so, so it's not such an
important issue.

If SBP-2 is what you get in a shop when asking for an external
Firewire disk enclosure then it's not sold as SCSI.

Agreed, and actually not fixing Kconfig UI problems will make the other
issues being fixed *slower* (because they result in *increased* workload
on developers' side).

This is why nowadays IDE DMA support is automatically selected by IDE
host drivers that need it - a big relief for everybody.

I don't know exactly what this option does...
Andi says it should be automatic rather than exposed as a prompt.

I useually have more screen space available to the side then above and

In this case, no bar is being "raised," for any user.

Irrelevant in this case, because there is no increased workload on the
developer's side.

Please don't take this any more off-topic than it already is.
IDE DMA option was vastly different. The options in question here
affect whether or not you have a block device to use -- something that
is immediately obviously and corrected quickly.

There is no problem, in this case.
Otherwise, there would be more than a complaint or two per year.

It has already been raised by making SATA configuration counterintuitive
(SATA has a separate Kconfig menu but depends on SCSI device drivers).

OK, I'll stop here and I'll just patiently wait till the SATA Kconfig
issue comes up again on LKML (then I'll just smile and move on to
the next post 8).

It is selling reasonably well for an O'Reilly book from what I have been
told. But I have not seen any real numbers yet.

The downloads are spread around all of the kernel.org mirrors so I have
absolutely no idea what they are.
Nor do I really want to, as it doesn't matter to me.

SCSI is a generic peripheral bus (recall the expansion of the acronym).
Even though probably the most common, storage is one of its applications
only (think scanners for an immediately obvious other one). I find
describing CONFIG_SCSI as "storage support" misleading and inappropriate.
Referring to your example it is like calling generic networking (i.e.
CONFIG_NET) "Ethernet support".

The expansion of the acronym doesn't fit anymore to what SCSI is today,
or even to what it became already circa 10 years ago.

Right. I wrote that in lack of better words, but at least I added "SCSI
commands" in parentheses. Something like "SCSI I/O - core and command
sets" would much better describe what it is, but it would put "SCSI"
first again and thus wouldn't reflect that Linux' SCSI core and
highlevel is in broader use than just for actual SCSI hardware... Of
course there is no way around the issue that Linux' SCSI core's and
highlevel's role cannot be characterized in 3...6 words only, but there
should be a way to point out its general importance.

Wrong comparison.
