* ahci: work around ATI SB600 h/w quirkJeff Garzik2008-03-05
| | | | | | | | | | | | | This addresses the recent ATI SB600 errata, where the hardware does not like 256-length PRD entries during FPDMA (aka NCQ). It hurts performance on SB600, but it is more important to get a correct patch eliminating the data corruption/lockups, and then later on tune for performance. We simply limit each command to a maximum of 255 sectors, on SB600. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* block: separate out padding from alignmentTejun Heo2008-03-04
| | | | | | | | | | | | | | | | Block layer alignment was used for two different purposes - memory alignment and padding. This causes problems in lower layers because drivers which only require memory alignment ends up with adjusted rq->data_len. Separate out padding such that padding occurs iff driver explicitly requests it.

* block: restore the meaning of rq->data_len to the true data lengthFUJITA Tomonori2008-03-04
| | | | | | | | | | | | | | | | | | The meaning of rq->data_len was changed to the length of an allocated buffer from the true data length. It breaks SG_IO friends and bsg. This patch restores the meaning of rq->data_len to the true data length and adds rq->extra_len to store an extended length (due to drain buffer and padding). This patch also removes the code to update bio in blk_rq_map_user introduced by the commit 40b01b9bbdf51ae543a04744283bf2d56c4a6afa. The commit adjusts bio according to memory alignment (queue_dma_alignment). However, memory alignment is NOT padding alignment. This adjustment also breaks SG_IO friends and bsg. Padding alignment needs to be fixed in a proper way (by a separate patch). Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <axboe@carl.home.kernel.dk>

This behavior has been confirmed by Marvell with a SATA analyzer. The Marvell port-multiplier apparently likes to see clean HOB information when accessing PMP registers. Since sata_mv uses PIO shadow register access, this doesn't happen automatically, as it might in a more purely FIS-based driver (eg. ahci). One way to fix this is to flag these commands with ATA_TFLAG_LBA48, forcing libata to write out the HOB fields with known (zero) values.

* libata: automatically use DMADIR if drive/bridge requires itTejun Heo2008-02-24
| | | | | | | | | | | | | | | | | | | | | | Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir. That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR.

* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

* libata: implement drain buffersJames Bottomley2008-02-19
| | | | | | | | | | | | | | | | | | | | This just updates the libata slave configure routine to take advantage of the block layer drain buffers. It also adjusts the size lengths in the atapi code to add the drain buffer to the DMA length so the driver knows it can rely on it. I suspect I should also be checking for AHCI as well as ATA_DEV_ATAPI, but I couldn't see how to do that easily. tj: * atapi_drain_needed() added such that draining is applied to only misc ATAPI commands. * q->bounce_gfp used when allocating drain buffer. * Now duplicate ATAPI PIO drain logic dropped. * ata_dev_printk() used instead of sdev_printk().

* libata: eliminate the home grown dma padding in favour ofJames Bottomley2008-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that provided by the block layer ATA requires that all DMA transfers begin and end on word boundaries. Because of this, a large amount of machinery grew up in ide to adjust scatterlists on this basis. However, as of 2.5, the block layer has a dma_alignment variable which ensures both the beginning and length of a DMA transfer are aligned on the dma_alignment boundary. Although the block layer does adjust the beginning of the transfer to ensure this happens, it doesn't actually adjust the length, it merely makes sure that space is allocated for transfers beyond the declared length. The upshot of this is that scatterlists may be padded to any size between the actual length and the length adjusted to the dma_alignment safely knowing that memory is allocated in this region. Right at the moment, SCSI takes the default dma_aligment which is on a 512 byte boundary. Note that this aligment only applies to transfers coming in from user space. However, since all kernel allocations are automatically aligned on a minimum of 32 byte boundaries, it is safe to adjust them in this manner as well. tj: * Adjusting sg after padding is done in block layer. Make libata set queue alignment correctly for ATAPI devices and drop broken sg mangling from ata_sg_setup(). * Use request->raw_data_len for ATAPI transfer chunk size. * Killed qc->raw_nbytes. * Separated out killing qc->n_iter.

* libata: update ATAPI overflow drainingTejun Heo2008-02-19
