2008-04-07[SCSI] ps3rom: use sg buffer copy helper funcitonsFUJITA Tomonori1-82/+10
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.

2008-04-07[SCSI] ps3rom: Simplify fill_from_dev_buffer()Geert Uytterhoeven1-16/+14
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().

2008-03-03[SCSI] ps3rom: disable clusteringFUJITA Tomonori1-1/+1
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).

2008-03-03[SCSI] ps3rom: fix wrong resid calculation bugFUJITA Tomonori1-1/+1
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)] Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-02-07[SCSI] ps3rom: sector size should be 512 bytesAegis Lin1-1/+1
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).
