2013-11-13libata: make ata_eh_qc_retry() bump scmd->allowed on bogus failuresGwendal Grignou
commit f13e220161e738c2710b9904dcb3cf8bb0bcce61 upstream. libata EH decrements scmd->retries when the command failed for reasons unrelated to the command itself so that, for example, commands aborted due to suspend / resume cycle don't get penalized; however, decrementing scmd->retries isn't enough for ATA passthrough commands. Without this fix, ATA passthrough commands are not resend to the drive, and no error is signalled to the caller because: - allowed retry count is 1 - ata_eh_qc_complete fill the sense data, so result is valid - sense data is filled with untouched ATA registers.

commit bb9696192826a7d9279caf872e95b41bc26c7eff upstream. sata_inic162x never reached a state where it's reliable enough for production use and data corruption is a relatively common occurrence. Make the driver generate warning about the issues and mark the Kconfig option as experimental. If the situation doesn't improve, we'd be better off making it depend on CONFIG_BROKEN.

2013-07-28libata: skip SRST for all SIMG [34]7x port-multipliersTejun Heo
commit 7a87718d92760fc688628ad6a430643dafa16f1f upstream. For some reason, a lot of port-multipliers have issues with softreset. SIMG [34]7x series port-multipliers have been quite erratic in this regard. I recall that it was better with some firmware revisions and the current list of quirks worked fine for a while. I think it got worse with later firmwares or maybe my test coverage wasn't good enough. Anyways, HPA is reporting that his 3726 setup suffers SRST failures and then the PMP gets confused and fails to probe the last port. The hope was that we try to stick to the standard as much as possible and soonish the PMPs and their firmwares will improve in quality, so the quirk list was kept to minimum. Well, it seems like that's never gonna happen. Let's set NO_SRST for all [34]7x PMPs so that whatever remaining userbase of the device suffer the least. Maybe we should do the same for 57xx's but unfortunately I don't have any device left to test and I'm not even sure 57xx's have ever been made widely available, so let's leave those alone for now.

2013-03-14ata_piix: reenable MS Virtual PC guestsOlaf Hering
commit d9904344fc4052fbe7e4dc137eba0dcdadf326bd upstream. An earlier commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c ("ata_piix: defer disks to the Hyper-V drivers by default") broke MS Virtual PC guests. Hyper-V guests and Virtual PC guests have nearly identical DMI info. As a result the driver does currently ignore the emulated hardware in Virtual PC guests and defers the handling to hv_blkvsc. Since Virtual PC does not offer paravirtualized drivers no disks will be found in the guest. One difference in the DMI info is the product version. This patch adds a match for MS Virtual PC 2007 and "unignores" the emulated hardware. This was reported for openSuSE 12.1 in bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=737532 Here is a detailed list of DMI info from example guests: hwinfo --bios: virtual pc guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "VS2005R2" Serial: "3178-9905-1533-4840-9282-0569-59" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "5.0" Serial: "3178-9905-1533-4840-9282-0569-59" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "5.0" Serial: "3178-9905-1533-4840-9282-0569-59" Asset Tag: "7188-3705-6309-9738-9645-0364-00" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) win2k8 guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" Asset Tag: "7076-9522-6699-1042-9501-1785-77" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) win2k12 guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" Asset Tag: "8374-0485-4557-6331-0620-5845-25" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-01-17sata_promise: fix hardreset lockdep errorMikael Pettersson
commit 3100d49d3cd236443faae9d81137c81b22d36003 upstream. sata_promise's pdc_hard_reset_port() needs to serialize because it flips a port-specific bit in controller register that's shared by all ports. The code takes the ata host lock for this, but that's broken because an interrupt may arrive on our irq during the hard reset sequence, and that too will take the ata host lock. With lockdep enabled a big nasty warning is seen. Fixed by adding private state to the ata host structure, containing a second lock used only for serializing the hard reset sequences. This eliminated the lockdep warnings both on my test rig and on the original reporter's machine.

This occurs using any disk in the enclosure, and when the disk is connected directly with a generic passive eSATAp cable, we see stable 3Gbps operation as expected.

commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c upstream. When we are hosted on a Microsoft Hyper-V hypervisor the guest disks are exposed both via the Hyper-V paravirtualised drivers and via an emulated SATA disk drive. In this case we want to use the paravirtualised drivers if we can as they are much more efficient. Note that the Hyper-V paravirtualised drivers only expose the virtual hard disk devices, the CDROM/DVD devices must still be enumerated. Mark the host controller ATA_HOST_IGNORE_ATA to prevent enumeration of disk devices.

git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev Pull libata updates from Jeff Garzik: 1) AHCI regression fix. A recent "make driver conform to spec" change broke on deployed hardware. Make new behavior optional, rather than default, turning it on only for specific embedded platforms that need this. Everybody else runs in the famous "non conformant but working" mode. 2) pata_cmd64x, pata_legacy cleanups 3) new Intel SATA PCI IDs 4) misc minor vendor feature additions * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: pata_cmd64x: implement sff_irq_check() method pata_cmd64x: implement sff_irq_clear() method pata_cmd64x: use interrupt status from MRDMODE register pata_cmd64x: turn string of *if* statements into *switch* drivers/ata/pata_mpc52xx.c: clean up error handling code ahci_platform: add STRICT_AHCI platform type ahci: move AHCI_HFLAGS() macro to ahci.h ahci: add AHCI_HFLAG_DELAY_ENGINE host flag sata_fsl: add support for interrupt coalsecing feature ata/pata_arasan_cf: Add Hibernation support pata_legacy: correctly mask recovery field for HT6560B ata_piix: IDE-mode SATA patch for Intel Lynx Point DeviceIDs ahci: AHCI-mode SATA patch for Intel Lynx Point DeviceIDs

2012-03-13pata_cmd64x: implement sff_irq_clear() methodSergei Shtylyov
Convert the driver's two bmdma_stop() methods into sff_irq_clear() methods -- they shouldn't have been bothering with clearing interrupts from the very start; the driver will now use the standard bmdma_stop() method implementation (where appropriate).

2012-03-13pata_cmd64x: use interrupt status from MRDMODE registerSergei Shtylyov
Start using faster version of the bmdma_stop() method for the PCI0646U and newer chips that have the duplicate interrupt status bits in the I/O mapped MRDMODE register. Use the old, slow bmdma_stop() method on the older chips, taking into account that the interrupt bits are not coupled to DMA and that's enough to read the register to clear the interrupt (on the older chips). Determine what method to use at the driver load time. Fix kernel-doc of the bmdma_stop() methods, while at it.
