Here are a lot of driver core patches for 2.6.14. They have all been in
the past few -mm releases with no problems. They contain the following
things:
- 2 small aoe driver updates
- create hotplug events directly from the sysfs tree so that
"coldplug" work at boot time is much simpler.
- add the ability to nest class devices in the driver model
- move the input drivers to have dynamic structures
- move the input subsystem to use the nested class devices
- remove the input core from calling /sbin/hotplug on its own.
- some driver core pm changes
- stop the i2o abuse of the driver model
- some other small things (documentation, bugfixes, etc.)
These patches are needed so that the different distros don't keep trying
to keep their own set of "fix up the input subsystem to play nice with
/sbin/hotplug" patches that they have been, in order to rely only on
udev to handle their hotplug needs. With these changes, they no longer
need to do that.
Please pull from:
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6.git/
or if master.kernel.org hasn't synced up yet:
master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6.git/
The full patch set will be sent to the linux-kernel mailing lists, if
anyone wants to see them.
thanks,
greg k-h

[PATCH] pci device wakeup flags
This patch teaches "pci_dev" about the new driver model wakeup support:
- It marks devices as supporting wakeup when "can issue PME#" is
listed in its PCI PM capability.
- pci_enable_wake() refuses to enable wake if that's been disabled
(e.g. through sysfs).
NOTE that a recent patch changed PCI probing, and this reverts part
of that change ... so that driver model initialization is again done
before the PCI setup.
(One issue is that the driver model "init + add == register" pattern isn't
being used inside PCI ... and that probe change worsened the problem by
making "add" do some "init" too. Maybe PCI should match the driver model
more closely, and just grow a new "pci_dev_init" function.)

[PATCH] usb device wakeup flags
This patch teaches "usb_device" about the new driver model wakeup support:
- It updates device wakeup capabilities when entering a configuration
with the WAKEUP attribute;
- During suspend processing it consults the policy bit to see
whether it should enable wakeup for that device. (This resolves
a FIXME to not assume the answer is always "yes"; some devices
lie about supporting remote wakeup.)
Support for root hubs and the HCDs is separate (and more complex).

[PATCH] driver model wakeup flags
This is a refresh of an earlier patch to add "wakeup" support to the
PM core model. This provides per-device bus-neutral control of the
use of wakeup events.
* "struct device_pm_info" has two bits that are initialized as
part of setting up the enclosing struct device:
- "can_wakeup", reflecting hardware capabilities
- "may_wakeup", the policy setting (when CONFIG_PM)
* There's a writeable sysfs "wakeup" file, with one of two values:
- "enabled", when the policy is to allow wakeup
- "disabled", when the policy is not to allow it
- "" if the device can't currently issue wakeups
By default, wakeup is enabled on all devices that support it. If its
driver doesn't support it ... treat it as a bug. :)

+ * Some devices support "wakeup" events, which are hardware signals
+ * used to activate devices from suspended or low power states. Such
+ * devices have one of three values for the sysfs power/wakeup file:
+ *
+ * + "enabled\n" to issue the events;
+ * + "disabled\n" not to do so; or
+ * + "\n" for temporary or permanent inability to issue wakeup.
+ *
+ * (For example, unconfigured USB devices can't issue wakeups.)
+ *
+ * Familiar examples of devices that can issue wakeup events include
+ * keyboards and mice (both PS2 and USB styles), power buttons, modems,
+ * "Wake-On-LAN" Ethernet links, GPIO lines, and more. Some events
+ * will wake the entire system from a suspend state; others may just
+ * wake up the device (if the system as a whole is already active).
+ * Some wakeup events use normal IRQ lines; other use special out
+ * of band signaling.
+ *
+ * It is the responsibility of device drivers to enable (or disable)
+ * wakeup signaling as part of changing device power states, respecting
+ * the policy choices provided through the driver model.
+ *
+ * Devices may not be able to generate wakeup events from all power
+ * states. Also, the events may be ignored in some configurations;
+ * for example, they might need help from other devices that aren't
+ * active, or which may have wakeup disabled. Some drivers rely on
+ * wakeup events internally (unless they are disabled), keeping
+ * their hardware in low power modes whenever they're unused. This
+ * saves runtime power, without requiring system-wide sleep states.

[PATCH] add sysfs attr to re-emit device hotplug event
A "coldplug + udevstart" can be simple like this:
for i in /sys/block/*/*/uevent; do echo 1 > $i; done
for i in /sys/class/*/*/uevent; do echo 1 > $i; done
for i in /sys/bus/*/devices/*/uevent; do echo 1 > $i; done

[PATCH] Driver Core: add the ability for class_device structures to be nested
This patch allows struct class_device to be nested, so that another
struct class_device can be the parent of a new one, instead of only
having the struct class be the parent. This will allow us to
(hopefully) fix up the input and video class subsystem mess.
But please people, don't go crazy and start making huge trees of class
devices, you should only need 2 levels deep to get everything to work
(remember to use a class_interface to get notification of a new class
device being added to the system.)
Oh, this also allows us to have the possibility of potentially, someday,
moving /sys/block into /sys/class. The main hindrance is that pesky
/dev numberspace issue...

[PATCH] I2O: remove i2o_device_class
I2O: cleanup - remove i2o_device_class
I2O devices reside on their own bus so there should be no reason
to also have i2c_device class that mirros i2o bus.

[PATCH] add sysfs support for ide tape
I was recently given an old Travan tape drive and asked to do something
useful with it. The ide-scsi + st (+serverworks ide controller) combo
results in a hard lockup of the machine which I have not had the energy to
debug, so I turned to ide-tape (which seems to work). The system in
question debian stable, using udev to manage /dev.
The following patch to ide-tape.c allows udev to create the cdev nodes for
my drive.

[PATCH] I2O: remove class interface
I2O: remove i2o_device_class_interface misuse
The intent of class interfaces was to provide different
'views' at the same object, not just run some code every
time a new class device is registered. Kill interface
structure, make class core register default attributes
and set up sysfs links right when registering class
devices.

Greg,
Is this solution for nesting class devices considered permanent or is it
a stop-gap measure? I hope it is latter as these 2 new methods allow one
class device walk all over class's intended interface and semantics and
you can no longer rely that objects of the same class have similar
characteristics/attributes and similar behavior. You already had to
abandon using class's default attributes when dealing with nested devices,
I think it is wrong long-term solution.
What about Kay's proposal about moving (as far as userspace concerned)
everything into /sys/devices?

The format change (%#d) should take an argument on stack, shouldn't
it? But there's nothing pushed? ...or is it just a typo?

I think I messed it up... Was probably trying to do "default" case and then
reverted back. Will fix.

NAK - explicit use of __nocast is wrong here.

This is the patch which I've been religiously dropping from -mm because it
kills my Mac G5. What are we doing merging this?

Well, since my main machine is a Mac G5, we certainly /aren't/ merging it
if it kills it.

Crap, sorry about that. I've deleted my tree and will rebuild it. I
thought that it was one of the usb patches in my tree that was causing
you problems. I'll not include this one until we get to the bottom of
it (and with David gone, that might take a while.)
Again, very sorry about this.
Oh, and I'll also drop the one from Randy with the gfp flags, and
properly attribute Russell's patch.

Ok, I've fixed up the issues people had with this tree. I've removed
the offending pci patch, the gfp_flag patch, added a documentation
patch, and (hopefully) proper attributed Russell's patch. I've also
merged against your latest tree.

Not ACKed. This patch contains a not-fixed (though reported) wrong
printk format in lkkbd_interrupt() "case LK_METRONOME:" Though I
haven't tested it yet, it's ACKed by me after this is fixed.

That can be a one-line add on patch once it is created. I can easily
send that later.

As I detalied a while ago, a stop-gap for now.

That's exactly what I am now working on. But it will take much longer
than 2.6.15 to get there for that. More like the next 6 months or so at
the least...

That's a separate problem. gregkh-usb-usb-pm-09.patch causes my x86 box to
hang partway though boot. I drop that from -mm as well.

Ugh, ok, at least I wasn't that far off. I'll make sure to not send the
usb pm patches in the round of usb updates until that gets figured out.

Just to verify: that one isn't in the current driver core tree, right? I
assume that's in Greg's USB tree..

Greg,
Any chance of putting my driver model changes into the driver core tree?
ISTR the reason they ended up in the USB tree was because they clashed
with the usb-pm patches. However, if the usb-pm patches are
problematical, I'd rather my driver model changes weren't held up.
Alternatively, I could ask Linus to take them directly from me if
you're happy for that to happen.

Yes, that is correct, that patch is not in this git tree that I asked
you to pull from. All of the patches that break Andrew's boxes will not
be sent to you until I figure out what is happening and fix them.

They are in there already. :)

They have not been held up. I made the required usb-pm fixups already,
based on your patches. They are dependant on your changes, not the
other way around.

Yah, that's a known one, the problem is due to the removal of
device_initialize() from pci_device_add(). The breaks the new mecanism
on ppc64 that creates the PCI tree from the firmware instead of probing
the bus. In addition, even with that fixed, the code looking for PME#
will not be run on the pmac neither.
I'm not 100% what is the best fix at this point. I suppose it would be 2
things, let me know what you think about it:
- Have the ppc64 PCI tree code call device_initialize() itself before
calling pci_device_add()
- Move the search of PME# (and possibly other similar bits) from probe
to pci_device_add()

That'll greatly help in debugging it if needed. Thanks.
If you really want to make that switch smaller, please put some small
table like
#define RESPONSE(x) { .value = x, .name = #x, }
struct {
unsigned char value;
unsigned char *name;
} response[] {
RESPONSE (LK_KBD_TEST_MODE_ACK),
RESPONSE (LK_PREFIX_KEY_DOWN),
...
};
into the driver along with a small search function like
unsigned char *
find_response_name (unsigned char value)
{
int i;
for (i = 0; i < ARRAY_SIZE (response); i++)
if (response[i].value == value)
return response[i].name;
return NULL;
}

The messages are only generated when someone explicitely enables LKKBD_DEBUG,
and if someone does enable it he surely can map the numeric values himself.
There is no need to clutter the code with insignificant details.

Actually, I think there is. It should just be easy to use; albeit
that, if you look precisely at it, there are some defines etc that
aren't even used. Why? Because it documents the hardware.
I didn't like the larce switch either, but I kept it there for a
reason. So I'd really like to keep the ability to print out these
values by name. I don't think it hurts, so please keep it there.
Here's a revised version of the patch, making the function and it's
data static, as well as stuffing them into #ifdef DEBUG.

Could we either get "not-supported" value here, or remove the file if it is not
supported? Having empty file is ugly...

If you could resend the patch with Signed-off-by line I would add it

Thanks a lot, so here it is, against current git.
This patch fixes three issues with the lkkbd.c driver:
* Fix a printk() format to match the stack
* Hide debugging code into #ifdef, which allows to simplify
the large switch statement
* Update macros to not reference variables not given as
arguments

Turns out that "remove if not supported" is impractical; I did have
that implemented, and backed it out as I got deeper into testing.
For one example, the "can wakeup" for USB devices is a function of what
configuration the device is in ... so a device with two configurations
(call them #5 and #42) as well as "unconfigured" (config #0) might
not support wakeup in two of its three states; maybe only #42 supports
remote wakeup.
Yes, those empty files bothered me a bit too.

BTW, is there a reason why "devices" is plural, as opposed to the
singular names used for other directories holding types of objects
("/sys/class" "/sys/bus" "/dev" "/lib" etc.)?

That's just the way it happened, no real "reason" behind it :)
