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.

2008-02-24libata: automatically use DMADIR if drive/bridge requires itTejun Heo
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. Original patch is from Mark Lord. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki
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.

2008-02-19libata: implement drain buffersJames Bottomley
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().

2008-02-19libata: eliminate the home grown dma padding in favour ofJames Bottomley
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.

2008-02-19libata: update ATAPI overflow drainingTejun Heo
For misc ATAPI commands which transfer variable length data to the host, overflow can occur due to application or hardware bug. Such overflows can be ignored safely as long as overflow data is properly drained. libata HSM implementation has this implemented in __atapi_pio_bytes() and recently updated for 2.6.24-rc but it requires further improvements. Improve drain logic such that... * Report overflow errors using ehi desc mechanism instead of printing directly. * Properly calculate the number of bytes to be drained considering actual number of consumed bytes for partial draining.

Maybe for the trivial tree... sata_via.c has PATA support since: d73f30e1c9a9af14757fa5bf4014343926047156 sata_via: PATA support AFAICS so the TODO list is no longer true. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2008-02-06sata_nv: fix ATAPI issues with memory over 4GB (v7)Robert Hancock
This fixes some problems with ATAPI devices on nForce4 controllers in ADMA mode on systems with memory located above 4GB. We need to delay setting the 64-bit DMA mask until the PRD table and padding buffer are allocated so that they don't get allocated above 4GB and break legacy mode (which is needed for ATAPI devices). Also, if either port is in ATAPI mode we need to set the DMA mask for the PCI device to 32-bit to ensure that the IOMMU code properly bounces requests above 4GB, as it appears setting the bounce limit does not guarantee that we will not try to map requests above this point.

qc->n_iter was used for libata's own sg walking before sg chaining replaced it. During conversion, the field and its usage in sata_fsl were left behind. Kill the filed and update sata_fsl. tj: This was part of James's libata-use-block-layer-padding patch. Separated out by me.

2008-02-06ahci: fix CAP.NP and PI handlingTejun Heo
AHCI uses CAP.NP to indicate the number of ports and PI to tell which ports are enabled. The only requirement is that the number of ports indicated by CAP.NP should equal or be higher than the number of enabled ports in PI. CAP.NP and PI carry duplicate information and there have been some interesting cases. Some early AHCI controllers didn't set PI at all and just implement from port 0 to CAP.NP. An ICH8 board which wired four out of six available ports had 3 (4 ports) for CAP.NP and 0x33 for PI. While ESB2 has less bits set in PI than the value in CAP.NP. Till now, ahci driver assumed that PI is invalid if it doesn't match CAP.NP exactly. This violates AHCI standard and the driver ends up accessing unmimplemented ports on ESB2. This patch updates CAP.NP and PI handling such that PI can have less number of bits set than indicated in CAP.NP and the highest port is determined as the maximum port of what CAP.NP and PI indicate.
