MACE DMA problem on Powermac 7300
Hi, everybody, I post this in hope that somebody could shed some light on how should the DMA work in conjunction with the MACE ethernet controller. I find difficult to understand why it does not work in my case: What happens? First two bytes of a received frame are not what they should be in more than 50% of frames. This can be avoided by receiving the frame on a word boundary, but with the usual skb_reserve(..., 2) (to make the IP header land on word boundary), it won't work. So, I can make the driver work by receiving at 0 offset, and then moving the data 2 bytes up, before handing it over to upper layers. This used to work with a 2.4.27 kernel, obviously the Grand Central DBDMA controller can receive on non-word boundaries. Now I have 2.6.15.7. Any ideas, what could cause this kind of behaviour (and regression)?

Re: using different format for hugetlbfs
Even than, does that preclude the format I suggested? I'm assuming that pgd_t/pud_t/pmd_t are always a double word so the low order 4- bits should be 0 (on 64-bit), so using the lsb as the flag between hugetlb and normal pointer should still work. Might do, depends if David has enough bits ... David ? Cheers, Ben. ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

[PATCH 4/4] powerpc: Set HZ=100 on pseries and ppc64 defconfigs
Now we have high res timers there is less of a reason for a high HZ value. Furthermore I think there a few reasons we should reduce HZ to 100: - Timer interrupt overhead. While this overhead is small, there are applications that are very sensitive to jitter (eg some HPC apps). - Issues with the timer wheel code. When coming out of NO_HZ idle we work our way through the timer code one tick at a time. If we have been idle a long time, this adds up - I sometimes see milliseconds of time spent in that loop. Long term we should fix the timer wheel algorithm, but for now if we reduce HZ then we reduce the amount of work the timer code has to do when coming out of idle.

[PATCH] offb: add support for framebuffer handoff to offb.
From: Dave Airlie airl...@ppcg5.localdomain
This allows offb to be used for initial framebuffer,
and a kms driver to take over later in the boot sequence.

dts file for MPC8343EA
Hi
We have an MPC8343EA based custom board.
I am not able to get Linux up and running in this. No serial output to debug
further.
U-boot shows correct 'bdinfo' 'clocks' output.
inux hangs at machine_probe.
I doubt the DTS file in Linux. anyone has DTS file for MPC8343??
u-boot version - 1.3.2
linux-2.6.27
The board base files are drived from MPC8349Imtx-GP since we have the reference
board in which we tested the linux image.
My current DTS file
