Great work. Many thanks for this. Running fine on my 2-week old SheevaPlug from NewIT.co.uk.

I was just wondering about the mvsdio driver, which seems to use a lot of interrupt as it uses polling.
Are there any patches out there to avoid polling, or is this a hardware issue?

Code:

$ cat /proc/interrupts
           CPU0
  1:     924575   orion_irq  orion_tick
  5:          2   orion_irq  mv_xor.0
  6:          2   orion_irq  mv_xor.1
  7:          2   orion_irq  mv_xor.2
  8:          2   orion_irq  mv_xor.3
 11:      70802   orion_irq  eth0
 19:       2832   orion_irq  ehci_hcd:usb1
 28:     607552   orion_irq  mvsdio
 33:        229   orion_irq  serial
 46:         24   orion_irq  mv643xx_eth
Err:          0

$ dmesg | grep -i mvs
mmc0: mvsdio driver initialized, lacking card detect (fall back to polling)

Cheers,
Jon.

Just plugging in my SD card reduced the interrupt rate to ~1Hz, which more-or-less fixed the problem from my point of view.  B^>

Dear cbxbiker61, i assume that you are the moderator of http://sheeva.with-linux.com/sheeva/

is there any change that you can include the 802.1q support in the future kernels?  ( so i can start using your kernels instead of building my one

This is for the people that use .1q for expanding the amount of Ethernet ports by trunking to a switch like me.


Thanks in advance,

Regards, AMSpilot01

Can I request:

I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING)

Unless there is a reason why they might not be a good idea.

I run my Sheeva rootfs from the internal NAND, and if I have a kernel with this, I can use iotop to see where the majority of my file writing is occuring.  (A good way to increase the life of my flash, and/or improve performance by relocating to faster media).

If this isn't a great idea for mainstream kernels, can I suggest a "specials" directory in sheeva-with-linux for one off testing stuff. (Clearly things are robust enough now they wouldn't have to be maintained every release).

Lastly, many thanks cxbiker, your kernel builds are awesome, and it means we don't need compiler enviroments on our plugs, or opening up to the world of hurt that is cross-compiling..

No problem.  I've just rebuild 2.6.31.6 (version 2) with 802.1q support.

Well I don't think the overhead that would go along with enabling those options justifies placing it in the standard kernel.  But as you suggest, I don't see a problem with creating a /testing directory for "special" testing versions.  After I figure out how I want to maintain a testing tree I'll get something uploaded there for you.  I'm busy working on other stuff, so it'll probably be a day or so.

May I please have the map file for this build?  I want to do some kernel debugging and I need to know the address of __log_buf.

OK, a taskstat enabled kernel is available under /sheeva/testing.

The 2.6.31.6 kernel now has a System.map in the appropriate directory.

[samweber]

Thanks, it is a very useful addition.  To wit:

1. Booted successfully (but the idea is that this should work even if the boot is not successful).

2. Pushed the reset button on the SheevaPlug and then interrupted the uboot autoboot countdown.

3. Used the value of __log_buf from the kernel build map file to display the log messages (after subtracting the value of CONFIG_PAGE_OFFSET).

may I request the inclusion of gspca driver for my Logitech QuickCam Communicate STX webcam in next releases?

Thanks for all your work!!

[Rabeeh Khoury]

cbxbikier:

can you please set the ramdisk size to be 8192 (instead of default 4096)?

this will solve the sheevaplug installer issue when using your kernels (since it seems initrd grew to be too big) !

The cspca drivers have been added to the 2.6.32 kernel.
