[SCSI] ps3rom: use sg buffer copy helper funcitons

2008-04-07T17:15:45+00:00

Note that if scsi_bufflen(cmd) is not zero, the command always has an
sg list. So this patch doesn't do the error checking in
fill_from_dev_buffer and fetch_to_dev_buffer did.

[SCSI] ps3rom: Simplify fill_from_dev_buffer()

2008-04-07T17:15:41+00:00

As we no longer need to calculate the data length of the whole scatterlist,
we can abort the loop earlier and coalesce req_len and act_len into one
variable, making fill_from_dev_buffer() more similar to fetch_to_dev_buffer().

[SCSI] ps3rom: disable clustering

2008-03-03T19:08:13+00:00

ps3rom does:

scsi_for_each_sg(cmd, sgpnt, scsi_sg_count(cmd), k) {
	kaddr = kmap_atomic(sg_page(sgpnt), KM_IRQ0);

We cannot do something like that with the clustering enabled (or we
can use scsi_kmap_atomic_sg).

[SCSI] ps3rom: fix wrong resid calculation bug

2008-03-03T19:06:37+00:00

sg driver rounds up the length in struct scatterlist to be a multiple
of 512 in some conditions. So LLDs can't use the data length in a sg
list to calculate residual. Instead, the length in struct scsi_cmnd
should be used.

[Geert: the variable buflen already contains scsi_bufflen(cmd)]

[SCSI] ps3rom: sector size should be 512 bytes

2008-02-08T00:02:33+00:00

It should be desired that 64 KiB is available for ATAPI transferrring.
(Historically) in SCSI/block layer sector size is defined as 512 during
sector-byte calculation.
Originally in ps3rom.c CD_FRAMESIZE (2048) was used, which limited
/sys/block/sr0/queue/max_sectors_kb to 16 KiB (32 sectors).
