2007-08-28[PATCH] Revert "pata_atiixp: add SB700 PCI ID"Willy Tarreau
That update broke build of pata_atiixp as it requires some PCI IDs and other updates which have not been merged. Better remove it from 2.6.20. This reverts commit f327bcd16db3128a6c1885e03109361e167d1a56. Signed-off-by: Willy Tarreau <w@1wt.eu>

2007-04-13fix lba48 bug in libata fill_result_tf()Mark Lord
2.6.21 fix lba48 bug in libata fill_result_tf() Current 2.6.21 libata does the following: void ata_tf_read(struct ata_port *ap, struct ata_taskfile *tf) { struct ata_ioports *ioaddr = &ap->ioaddr; tf->command = ata_check_status(ap); ... if (tf->flags & ATA_TFLAG_LBA48) { iowrite8(tf->ctl | ATA_HOB, ioaddr->ctl_addr); tf->hob_feature = ioread8(ioaddr->error_addr); ... } } ... static void fill_result_tf(struct ata_queued_cmd *qc) { struct ata_port *ap = qc->ap; ap->ops->tf_read(ap, &qc->result_tf); qc->result_tf.flags = qc->tf.flags; } Based on this, those last two statements fill_result_tf() appear to me to be in the wrong order, in that the tf->flags are uninitialized at the point where tf_read() is invoked. So for lba48 commands, tf_read() won't be reading back the full lba48 register contents.. Correct? This patch corrects fill_result_tf() so that the flags get copied to result_tf before they are used by tf_read().

2007-04-13ahci.c: walkaround for SB600 SATA internal error issueConke Hu
ahci.c: walkaround for SB600 SATA internal error issue There is a HW issue in ATI SB600 SATA that PxSERR.E should not be set on some conditions, for example, when there is no media in SATA CD/DVD drive or media is not ready, AHCI controller fails to execute ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA controller sets PxSERR.E at the same time, which is not necessary. This patch is just to ignore the INTERNAL ERROR in such case. Without this patch, ahci error handler will report many errors as below: ----------- cut from dmesg ----------- ata9: soft resetting port ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata9.00: configured for UDMA/33 ata9: EH complete ata9.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata9.00: (irq_stat 0x40000001) ata9.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 51/24:03:00:00:20/00:00:00:00:00/a0 Emask 0x40 (internal error) ata9: soft resetting port ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata9.00: configured for UDMA/33 ata9: EH complete ata9.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata9.00: (irq_stat 0x40000001) ata9.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x43 data 12 in res 51/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x40 (internal error) -------- end cut --------- Signed-off-by: Conke Hu <conke.hu@amd.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Cc: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-04-06libata bugfix: HDIO_DRIVE_TASKMark Lord
libata bugfix: HDIO_DRIVE_TASK I was trying to use HDIO_DRIVE_TASK for something today, and discovered that the libata implementation does not copy over the upper four LBA bits from args[6]. This is serious, as any tools using this ioctl would have their commands applied to the wrong sectors on the drive, possibly resulting in disk corruption. Ideally, newer apps should use SG_IO/ATA_16 directly, avoiding this bug. But with libata poised to displace drivers/ide, better compatibility here is a must. This patch fixes libata to use the upper four LBA bits passed in from the ioctl. The original drivers/ide implementation copies over all bits except for the master/slave select bit. With this patch, libata will copy only the four high-order LBA bits, just in case there are assumptions elsewhere in libata (?).

2007-03-09sata_sil: ignore and clear spurious IRQs while executing commands by pollingTejun Heo
sata_sil used to trigger HSM error if IRQ occurs during polling command. This didn't matter because polling wasn't used in sata_sil. However, as of 2.6.20, all IDENTIFYs are performed by polling and device detection sometimes fails due to spurious IRQ. This patch makes sata_sil ignore and clear spurious IRQ while executing commands by polling. This fixes bug#7996 and IMHO should also be included in -stable.

2007-02-02ahci/pata_jmicron: fix JMicron quirkTejun Heo
For all JMicrons except for 361 and 368, AHCI mode enable bits in the Control(1) should be set. This used to be done in both ahci and pata_jmicron but while moving programming to PCI quirk, it was removed from ahci part while still left in pata_jmicron. The implemented JMicron PCI quirk was incorrect in that it didn't program AHCI mode enable bits. If pata_jmicron is loaded first and programs those bits, the ahci ports work; otherwise, ahci device detection fails miserably. This patch makes JMicron PCI quirk clear SATA IDE mode bits and set AHCI mode bits and remove the respective part from pata_jmicron. Tested on JMB361, 363 and 368.

2007-01-30libata: fix translation for START STOP UNITRobert Hancock
libata's SCSI translation for the SCSI START STOP UNIT command with the START bit clear (i.e. stopping the drive) appears to be incorrect. It sends an ATA STANDBY command with the time period set to 0, which the code comment says means "now", but the ATA standard says this means disable the standby timer, which effectively does nothing. Change this to issue a STANDBY IMMEDIATE command which will actually spin the drive down. The SAT (SCSI/ATA Translation) standard revision 9 concurs with this choice.

2007-01-26Fix Maple PATA IRQ assignment.David Woodhouse
On the Maple board, the AMD8111 IDE is in legacy mode... except that it appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by the architecture's "pci_get_legacy_ide_irq()" function, but in libata we just hard-code the numbers 14 and 15. This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as appropriate, having added a pci_dev argument to the ATA_{PRIM,SECOND}ARY_IRQ macros. There's probably a better way to do this -- especially if we observe that the _only_ case in which this seemingly-generic "pci_get_legacy_ide_irq()" function returns anything other than 14 and 15 for primary and secondary respectively is the case of the AMD8111 on the Maple board -- couldn't we handle that with a special case in the pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into native mode during early boot and assign resources properly?

2007-01-24ahci: don't enter slumber on power downTejun Heo
Some ATA/ATAPI devices act weirdly after the link is put into slumber mode. Some hang completely requiring physical power removal while others fail to wake up till the link is hardreset a couple of times. The addition of slumber on power down was never driven by real need. It just followed what ahci spec said literally. The spec itself seems faulty in that it doesn't consider devices (not controllers) which don't support link powersaving mode. Theory never matches reality when it comes to dark allys of cheap ATA/ATAPI world. It's just unrealistic to expect vendors to test rarely used link powersaving feature rigorously. This patch makes ahci more friendly to the coldness of reality. This shouldn't have any negative effect - when suspend operation succeeds, we power off the whole machine; otherwise, we wake up everything. I can't see any reason to be so elaborate with powering down the link in the first place. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-01-24sata_nv: don't rely on NV_INT_DEV indication with ADMARobert Hancock
Several people reported issues with certain drive commands timing out on sata_nv controllers running in ADMA mode. The commands in question were non-DMA-mapped commands, usually FLUSH CACHE or FLUSH CACHE EXT. From experimentation it appears that the NV_INT_DEV indication isn't always set when a legitimate command completion interrupt is received on a legacy-mode command, at least not on these controllers in ADMA mode. When a command is pending on the port, force the flag on always in the irq_stat value before calling nv_host_intr so that the drive busy state is always checked by ata_host_intr. This also fixes some questionable code in nv_host_intr which called ata_check_status when a command was pending and ata_host_intr returned "unhandled". If the device interrupted at just the wrong time this could cause interrupts to be lost. Signed-off-by: Robert Hancock <hancockr@shaw.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-01-19libata: fix handling of port actions in per-dev action maskTejun Heo
libata EH ignores port-wide actions in per-dev action mask. However, device resume requests EH_SOFTRESET using per-dev action mask. Under certain circumstances, this results in not resetting frozen port after resuming which causes failure of all commands. This patch allows port-wide actions to be requested in per-dev action mask. Before EH recovery starts, port-wide actions will be collected. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
