git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev Pull libata updates from Jeff Garzik: 1) apply, and then revert, the sysfs export of ATA host controller number. Discussion was continuing after patch application, trying to figure out how to best mesh exported data with the installers, boot-time agents and other parties that want this info. 2) Merge Zero-Power Optical Device Driver (ZPODD) support, bringing the wonderfulness of sane power management to your CD/DVD device. Includes one SCSI-subsystem patch (with appropriate ACKs), adding runtime PM support to 'sr' driver. That is the ZPODD interaction bits. Patchset went through some 13 revisions before it got here; kudos to Intel for persistence. 3) pata_samsung_cf: use devm_clk_get() 4) more ata_piix, ahci PCI IDs 5) Add SATA driver for R-Car SoC 6) Convert libata to use devm_ioremap_resource (Note: I think Greg sent this to you, also) 7) Set proper Sense Key (SK) in the SCSI simulator when ATA passthrough indicates check condition.

2013-01-24AHCI: Support multiple MSIsAlexander Gordeev
Take advantage of multiple MSIs implementation on x86 - on systems with IRQ remapping AHCI ports not only get assigned separate MSI vectors - but also separate IRQs. As result, interrupts generated by different ports could be serviced on different CPUs rather than on a single one. In cases when number of allocated MSIs is less than requested the Sharing Last MSI mode does not get used, no matter implemented in hardware or not. Instead, the driver assumes the advantage of multiple MSIs is negated and falls back to the single MSI mode as if MRSM bit was set (some Intel chips implement this strategy anyway - MRSM bit gets set even if the number of allocated MSIs exceeds the number of implemented ports).

2010-10-22libata: reimplement link power managementTejun Heo
The current LPM implementation has the following issues. * Operation order isn't well thought-out. e.g. HIPM should be configured after IPM in SControl is properly configured. Not the other way around. * Suspend/resume paths call ata_lpm_enable/disable() which must only be called from EH context directly. Also, ata_lpm_enable/disable() were called whether LPM was in use or not. * Implementation is per-port when it should be per-link. As a result, it can't be used for controllers with slave links or PMP. * LPM state isn't managed consistently. After a link reset for whatever reason including suspend/resume the actual LPM state would be reset leaving ap->lpm_policy inconsistent. * Generic/driver-specific logic boundary isn't clear. Currently, libahci has to mangle stuff which libata EH proper should be handling. This makes the implementation unnecessarily complex and fragile. * Tied to ALPM. Doesn't consider DIPM only cases and doesn't check whether the device allows HIPM. * Error handling isn't implemented. Given the extent of mismatch with the rest of libata, I don't think trying to fix it piecewise makes much sense. This patch reimplements LPM support. * The new implementation is per-link. The target policy is still port-wide (ap->target_lpm_policy) but all the mechanisms and states are per-link and integrate well with the rest of link abstraction and can work with slave and PMP links. * Core EH has proper control of LPM state. LPM state is reconfigured when and only when reconfiguration is necessary. It makes sure that LPM state is reset when probing for new device on the link. Controller agnostic logic is now implemented in libata EH proper and driver implementation only has to deal with controller specifics. * Proper error handling. LPM config failure is attributed to the device on the link and LPM is disabled for the link if it fails repeatedly. * ops->enable/disable_pm() are replaced with single ops->set_lpm() which takes @policy and @hints. This simplifies driver specific implementation. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2010-09-28ahci: fix module refcount breakage introduced by libahci splitTejun Heo
libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

For yet unknown reason, MCP89 on MBP 7,1 doesn't work w/ ahci under linux but the controller doesn't require explicit mode setting and works fine with ata_generic. Make ahci ignore the controller on MBP 7,1 and let ata_generic take it for now. Reported in bko#15923. https://bugzilla.kernel.org/show_bug.cgi?id=15923 NVIDIA is investigating why ahci mode doesn't work.

2010-05-14ahci: implement AHCI_HFLAG_NO_FPDMA_AA and update NV quirksTejun Heo
It turns out different generations of MCPs have differing quirks. * MCP 65-73 : FPDMA AA broken, lies about PMP support, forgets to report NCQ * MCP 77-79 : FPDMA AA broken, lies about PMP support * MCP 89 : FPDMA AA broken Instead of turngin off FPDMA AA on all NVIDIAs, implement HFLAG_NO_FPDMA_AA, define additional board IDs and apply necessary quirks. This fixes bko#15481 and the list of quirks is verified by Peer Chen. http://bugzilla.kernel.org/show_bug.cgi?id=15481 Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Peer Chen <pchen@nvidia.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2010-05-14ahci: clean up board IDsTejun Heo
ahci over time has grown a number of board IDs and it's a bit of mess right now. Clean it up such that, * board_id_* now live in a separate enum board_ids and numbers are assigned automatically. * Board IDs assigned to features are separated from the ones assigned to specific implementations and both are ordered alphabetically. * For NV MCPs, define per-generation alias board_ids and assign matching aliases in the pci id table. This makes mcp_linux, 67-73 use board_ahci_mcp65 instead of board_ahci_yesncq. Both are identical in content. * Kill now unused board_ahci_nopmp and board_ahci_yesncq. This patch doesn't cause any functional change but will make future changes to board_ids and quirks much less painful.
