Any users of hitfb?

Just want to see if there is anyone else out there
needing hitfb for their platform?

repeated oops under load on SH4 system

Hello all.

I've got repeated oops message  under a load on kernel 2.6.26.7.
It happens once or twice per a week with the below message.

>Unable to handle kernel paging request at virtual address dfff0700
>Unable to handle kernel paging request at virtual address dfff1000
>Unable to handle kernel paging request at virtual address dfff0a00

I have been gotten this message from around kernel 2.6.23. I didn't
test before it.
My hardware is mach-landisk with attached .config.
The root file system is on nfs server.
Please let me know if  you need more information to investigating the problem.
Could somebody give me a hint to resolve the issue ?

Thanks in advance.

Full oops message is here.

smsc911x in 2.6.29

Hi all,

I recently posted a patchset on netdev to replace smc911x with a new 
vendor-supported smsc911x driver:

    http://marc.info/?l=linux-netdev&m=122588138425309&w=4

Jeff Garzik has merged the driver itself for net-next (2.6.29).

3 of the patches convert sh platforms (rsk7203, ap325rxa & magicpanelr2) 
from one driver to the other, but I don't have access to any of these 
platforms to test.  Can anyone here help?

Please let me know if anyone wants me to re-send them the whole patchset 
(6 patches).

Regards,

OK,  I will test and report about rsk7203 and ap325rxa.
Thank you for your work!

[RFC patch 11/18] LTTng timestamp sh

This patch adds the timestamping mechanism in the trace-clock.h arch header
file. The new timestamp functions use the TMU channel 1.

This code only works if the TMU channel 1 is initialized during the kernel boot.

Big fat warning(TM) from Mathieu Desnoyers :

This patch seems to assume TMU channel 1 is setup at boot. Is it always true on
all SuperH boards ? Is there some Kconfig selection that should be done here ?
Make sure this patch does not break get_cycles on SuperH before merging.

Qemu sh4 kernel?

Hi,

Thought I would give the latest qemu a try. I fail to 
compile a working kernel for it though.
I thought the defconfig for the rts7751.. would work?

Anyone got a config handy?

Concerning Qemu SH4

Greetings,

Oki, gotten it to work now. Whats left is putting some sort 
of harddrive file there. I've created an loop file but
can't seem to get it going.
As any sh kernel it uses scsi emulation (hda->sda) while
qemu expects harddrives on hda/b/c.

I'm also missing something with the initrd as it
constantly claims that the initrd expands beyond
the memory boundry.

Have you applied all patches on ML?
Otherwise it doesn't support hard disk.
QEMU repository is being maintained very slowly.
There always many patches left on ML waiting for being merged.

Now, following patches are pending.
http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg00970.html
 This must be applied. Otherwise it will be crashed frequently.
http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg01246.html
http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg01247.html
http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg01248.html
 These three are needed use to use HDD.
http://lists.gnu.org/archive/html/qemu-devel/2008-11/msg00118.html
http://lists.gnu.org/archive/html/qemu-devel/2008-11/msg00119.html
 These two are needed to use network.

Some of them can't be applied cleanly, because other patch has been
 applied after I posted them. Please edit them manually.

Current code doesn't support --initrd nor --append.
Only --kernel works. Use initramfs and initial command line.
