However, as of 2.5, the block layer has a\ndma_alignment variable which ensures both the beginning and length of a\nDMA transfer are aligned on the dma_alignment boundary. Although the\nblock layer does adjust the beginning of the transfer to ensure this\nhappens, it doesn\u0027t actually adjust the length, it merely makes sure\nthat space is allocated for transfers beyond the declared length. The\nupshot of this is that scatterlists may be padded to any size between\nthe actual length and the length adjusted to the dma_alignment safely\nknowing that memory is allocated in this region.\n\nRight at the moment, SCSI takes the default dma_aligment which is on a\n512 byte boundary. Note that this aligment only applies to transfers\ncoming in from user space. However, since all kernel allocations are\nautomatically aligned on a minimum of 32 byte boundaries, it is safe to\nadjust them in this manner as well.\n\ntj: * Adjusting sg after padding is done in block layer.

It seems the device raises IRQ too early after\nSETXFER. This is controller independent. The same problem has been\nreported for different controllers.\n\nSo, now we have pata_via where the controller raises IRQ before it\u0027s\nready after SETXFER and a device which does similar thing. This patch\nmakes libata always execute SETXFER via polling. As this only happens\nduring EH, performance impact is nil. Setting ATA_TFLAG_POLLING is\nalso moved from issue hot path to ata_dev_set_xfermode() - the only\nplace where SETXFER can be issued.\n\nNote that ATA_TFLAG_POLLING applies only to drivers which implement\nSFF TF interface and use libata HSM. More advanced controllers ignore\nthe flag. This doesn\u0027t matter for this fix as SFF TF controllers are\nthe problematic ones.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "bc9a8a7eaa58d802a2b26c75edcc95cb92835db3", "tree": "202250109e861ae2ba6dfd2fa407b1b7487dca68", "parents": [ "2f91d81db3060f6d218e32d935b9a18ffca4dde2" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Mon May 21 15:20:33 2007 +0100" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Mon May 21 20:00:54 2007 -0400" }, "message": "libata: Kiss post_set_mode goodbye\n\nAs of the -mm tree we don\u0027t have post_set_mode users any more.\n\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "13b8d09f5de0aaa3153bbccc98baf247387823dc", "tree": "d35c90bd2460d7808595917ccf7c102229353365", "parents": [ "da071b42f73dabbd0daf7ea4c3ff157d53b00648" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Tue May 15 12:29:22 2007 +0200" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Wed May 16 01:18:31 2007 -0400" }, "message": "libata: track spindown status and skip spindown_compat if possible\n\nOur assumption that most distros issue STANDBYNOW seems wrong.
