Subject: Regarding the linkstation defconfig

Hi, Guennadi, Kumar & Co.

Guennadi, since you seem to be the one responsible for the
linkstation/kurobox in the kernel, I would like to ask you a few things
that I couldn't quite understand. Please, forgive my ignorance here
while I ask you some things:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
01. why is anticipatory the default scheduler for linkstations when CFQ
is the default scheduler for the rest of the kernel?

02. since kuroboxes/linkstations are meant to store files, is there any
reason why they don't have support for large blk devs enabled by
default?

03. why is CONFIG_MIGRATION enabled in such low memory devices?

04. why is CONFIG_BLK_DEV_RAM enabled by default?

05. why is SCSI_LOWLEVEL enabled, if no device under that tree is used?

06. idem for CONFIG_NETDEV_10000.

07. idem for CONFIG_WIRELESS.

08. idem for CONFIG_HWMON.

09. idem for CONFIG_CRYPTO_HW.

10. any reason why CONFIG_VIDEO_OUTPUT_CONTROL is configured as a
module?

11. any reason why CIFS is not configured with extended attributes,
while both ext3 and nfs are?

12. wouldn't it be a good thing to enable CONFIG_PRINTK_TIME?
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Perhaps similar remarks would apply to the other device that you
maintain? I forgot its name.

Again, please, forgive my ignorance here regarding the questions above.
I'm really looking for some clarification and to get things in shape
both on my systems and in the default kernel configuration, in general.

Thank you very much for your contributions, Rogério Brito.

That's not howI interpret my role in linkstation development / support.

As I already replied to you earlier, I am not particularly interested in
fine-tuning and optimisation of defconfigs. IMHO *_defconfigs are only
examples of board configuration, that are known to build and work. The
rest is up to the user / packager.

Feel free to submit patches with reasoning to the powerpc ML and
respective maintainer as per MAINTAINERS file.

Thanks

Sorry. I thought that you were. I have, nonetheless, interest in helping
and understanding more about the platform.

IMVHO, defconfigs should be examples of board configuration, known to
build and work (like you said) *and* be, in a way, exemplary to the
user/packager.

I'm doing that as a reply to this message.

Thanks for your guiding, Rogério Brito.

Subject: [PATCH] powerpc: minimizing the configuration of linkstation_defconfig

This patch addresses the following issues:

01. makes CFQ the default scheduler, to be in line with the rest of the kernel.

02. since linkstations are meant to store files, enable large blk devices.

03. disable CONFIG_MIGRATION in in such low memory devices.

04. disable CONFIG_BLK_DEV_RAM.

05. disable CONFIG_SCSI_LOWLEVEL, as no device under that tree is used.

06. idem for CONFIG_NETDEV_10000.

07. idem for CONFIG_WIRELESS.

08. idem for CONFIG_HWMON.

09. idem for CONFIG_CRYPTO_HW.

10. disable CONFIG_VIDEO_OUTPUT_CONTROL.

11. keep consistency and disable extended attributes in CIFS, ext3, and NFS.

12. enable CONFIG_PRINTK_TIME.

Dear Kumar, please, apply this one.

I have another patch regarding one regression regarding MTD &
PHYSMAP_COMPAT that I plan to send on top of this one.

Thanks.

do we not allow booting a ramdisk?

Ok, can we look at just specifying such info in the linkstation device
tree.

Also, can you break this defconfig update into two patches. 1. that
just updates to 2.6.30-rc3 (or latest) and 2. that makes the various
changes you've listed above.

Well, do we need a block device in ram to use initramfs?

Thanks. The MTD & PHYMAP_COMPAT are the things that have been bugging me
and my main reason to keep with the bleeding edge kernels is to get things
whey they were (regarding mtd) as in kernel 2.6.28.

As I have no experience with MTD devices, I would appreciate a reference to
their workings... All that I know is that all my /dev/mtd* devices are gone
if I boot a 2.6.29* kernel.

Of course, I can do a git bisect process (since the MTD subsystem doesn't
work as it did in the past even if I enable PHYMAP_COMPAT and put the same
settings there, quite unfortunately).

No problems with that. I will do that ASAP. Thanks for your kind comments.

Regards, Rog?rio Brito.

P.S.: Guennadi, did you see any regressions with your linkstation/kurobox
HG or whatever device you have?

I'm pretty sure we need this for old initrd style ramdisks so I'd
prefer we leave it enabled.

Oh, for oldstyle it is needed. You're right. It is better to keep it in
the defconfig. Just drop the hunk from the patch that I sent you.

I will post the problems that I get with MTD on my kurobox so that

happening and suggest some fixes.

Thanks, Rogério Brito.
