As soon as I finish SATA ATAPI (this week[end]), I'll take a look at
this. A quick review of the patches didn't turn up anything terribly
objectionable, though :)
I would like to offer to test when you are ready
So, one thing that's terribly ugly about SATA ATAPI is that we need to
pad DMA transfers to the next 32-bit boundary, if the length is not
evenly divisible by 4.
Messing with the scatterlist to accomplish this is terribly ugly
no matter how you slice it. One way would be to create my own
is not linked into the kernel,
SCSI_SATA_AHCI is built modular (unresolved symbols due to missing
libata)

Hi,
This is my second post on this issue, in the hopes
that someone can enlighten me, or point me off to the
right resource for this problem.
I can mount my Plextor 712 SA DVD burner read-only,
but I can't mount it read-write. I have an Intel ICH6

Jeff,
PATCH 2/3: ata_data_xfer() fix
Changes:
- Add ATA_FLAG_IO_32BIT to libata.h for hosts with 32-bit data register.
- Modify ata_mmio_data_xfer() and ata_pio_data_xfer() to handle buffer
length
not aligned to 32-bit boundary.
This patch does not reuse ap-pad as

Jeff,
PATCH 3/3:
Sometimes the device returns/needs extra data than expected.
Changes:
- Modify __atapi_pio_bytes() to handle the case when device
returns/needs extra data.
- for read case, discard trailing data from the device
- for write case, padding zero data

NCQ support is under development. Search

Oh, and forget TCQ. It's a completely worthless technology inherited
from PATA,
Agreed.
There are a few controllers where we may -eventually- add TCQ support,
controllers that do 100% of TCQ in hardware. But that's so far down the
priority list, it's below just about

Hi Tejun; I'm the guy at Google working on SATA drivers (port
multipliers right now). As soon as I can (next week perhaps, I'll start
looking at the driver you wrote. From what I can see, it looks quite good.

One question. Do the open source driver support pass-through commands ? if
so, how ? If you do not support it, are you planning to implement
pass-through commands sometime in the future ?
I don't know about sata_sil24 in

Is there a possibility that dell attaches PATA harddisks using a

That chipset is used in virtually all modern laptops,

The PATA ATAPI works now -- perhaps it could be turned on by default
while efforts continue to implement support for SATA ATAPI devices.
No, PATA ATAPI DMA still needs the same fixes that SATA ATAPI does.
