Trouble compiling kernel for G5.

Trouble compiling kernel for G5.

[Stefan Berndtsson]

When trying to compile the latest rsynced kernel (checked today, 2004-01-09)
from source.mvista.com::linuxppc-2.5-benh (2.6.1-rc1-ben1) for my G5, I
run into the following message with SATA:

  CC      drivers/scsi/sata_svw.o
drivers/scsi/sata_svw.c:236: error: request for member `bios_param' in something not a structure or union
drivers/scsi/sata_svw.c:236: error: initializer element is not constant

make[2]: *** [drivers/scsi/sata_svw.o] Error 1
make[1]: *** [drivers/scsi] Error 2
make: *** [drivers] Error 2

My .config can be found at http://stefan.nocrew.org/config-g5.txt

GCC version is 3.3.3, currently running kernel 2.6.0-test10.

Anything else needed from me?

Figured from the other mails that mvista wasn't up to date at the point,
so with a 2.6.1-ben1 it compiled and booted fine. Thanks.

Any news on when DVD-writing will be possible with DMA turned on?

It doesn't work at the moment ?

When I, on the G5, run:

growisofs -Z /dev/hda -dvd-video dvddir

I get:

ide0, timeout waiting                   for dbdma command stop
ide-cd: dma error
hda: DMA disabled
hda: dma error: status=0x50 { DriveReady SeekComplete }
hda: dma error: error=0x00
cdrom_newpc_intr: 4 residual after xfer
cdrom_newpc_intr: 4 residual after xfer

And hdparm shows the drive to no longer have DMA turned on, which it did
before running growisofs.

The same command on a B&W G3 runs fine with DMA (2.4.23 kernel).

So, to answer your question, it seems it does not work, no.

Look like an underrun again, or an alignement problem as there
seem to be something weird with the DBDMA on the G5 at least
(there is some "workaround" code in darwin that I haven't been
able to understand fully yet).

Ok, I'll just sit tight and wait a bit then. :)
