[PATCH #upstream-fixes] ata_piix: add borked Tecra M4 to broken suspend list

Tejun Heo — 2008-11-29T13:37:21

Tecra M4 sometimes forget what it is and reports bogus data via DMI which makes the machine evade broken suspend matching and thus fail suspend/resume. This patch updates piix_broken_suspend() such that it can match such case. As the borked DMI data is a bit generic, matching many entries to make the match more specific is necessary. As the usual DMI matching is limited to four entries, this patch uses hard coded manual matching. This is reported by Alexandru Romanescu.

[PATCH #upstream-fixes] libata: blacklist Seagate drives which time out FLUSH_CACHE when used with NCQ

Tejun Heo — 2008-11-27T04:36:48

Some recent Seagate harddrives have firmware bug which causes FLUSH CACHE to timeout under certain circumstances if NCQ is being used. This can be worked around by disabling NCQ and fixed by updating the firmware. Implement ATA_HORKAGE_FIRMWARE_UPDATE and blacklist these devices.

[PATCH 0/2] libata: Cavium OCTEON SOC Compact Flash driver (v2)

David Daney — 2008-11-25T01:36:48

As part of our efforts to get the Cavium OCTEON processor support merged (see: http://marc.info/?l=linux-mips&m=122704699515601), I have a new version of our CF driver for your consideration.

ata_pio_need_iordy vs. CF spec. V4.1

David Daney — 2008-11-24T17:40:10

Table 22 on page 51 of CF Specification Rev. 4.1 indicates that iordy is not supported in PIO5 and PIO6. This seems to be in conflict with the code in ata_pio_need_iordy, which asserts that it is mandatory in any mode greater than PIO2. Which is correct? Or am I misreading something?

[PATCH] Resurrect IT8172 IDE controller driver

Shane McDonald — 2008-11-24T06:21:33

Support for the IT8172 IDE controller was removed from the kernel sometime after 2.6.18. Support for the only boards that used the IT8172 was removed from the kernel after 2.6.18, as they had never compiled since 2.6.0. However, there are a couple of platforms that use this chip: the PMC-Sierra Xiao Hu thin-client computer, which is no longer in production, and the Linksys NSS4000 Network Attached Storage box, which is based on the Xiao Hu board. I am attempting to add support for the Xiao Hu to the kernel, and this IT8172 IDE controller is the first bit of code in this effort. This patch resurrects the IT8172 IDE controller code. I began with the 2.6.18 version of the it8172.c file, and have moved it forward so that it works with the latest version of the kernel. I have run this driver on a PMC-Sierra Xiao Hu board with the 2.6.28-rc6 kernel, and I have had no problems with it in my configuration. The attached patch applies cleanly against 2.6.28-rc6.

about TRIM/DISCARD support and barriers

Tejun Heo — 2008-11-23T04:46:08

Hello, all. Dongjun Shin who works for Samsung SSD dep asked me about libata TRIM support and pointed me to the new DISCARD support David Woodhouse got merged for 2.6.28. I took a look at the code and blk-layer interface-wise we seemed to be ready both for filesystems and userland (so that fsck or something which runs background can mark unused blocks) but there doesn't seem to be any low level driver which actually implements ->prepare_discard_fn or fs which sets the DISCARD flag. Adding ->prepare_discard_fn wouldn't be difficult at all but I became curious about a few things after looking at the DISCARD interface. First of all - how to avoid racing aginst reusing and how to schedule DISCARDs. * There are two variants of DISCARD - DISCARD w/o barrier and DISCARD w/ barrier, if a fs uses the former, it would need to make sure that it the DISCARD finishes before re-using the block. Block layer will make sure order will be kept for the latter but depending on how often those DICARDs are issued it

Drive failure and ASUS

Gene Heskett — 2008-11-22T14:01:33

Greetings; The only way I can get this box to boot is to disconnect the data cable on a drive with 121 badblocks as somehow ASUS and JMicron-pata all seem to think its /dev/sda when hooked up, and it is no longer bootable. I'm presently booted from a sata drive on that interface, which this ASUS board has about 8 of. So I've booted with the data cable off, and hooked it up once booted. Unforch there seems to be no discovery of its presence. No /dev/sdd stuff was created when I plugged the data cable into the drive. The install is the August 2008 F8 respin and is uptodate. How can I make the system aware that it is now there? It has about 40 Gb of data I'd like to recover if I can. Thanks.

[PATCH] amd74xx: workaround unreliable AltStatus register for nVidia controllers

Bartlomiej Zolnierkiewicz — 2008-11-21T21:38:50

It seems that on some nVidia controllers using AltStatus register can be unreliable so default to Status register if the PCI device is in Compatibility Mode. In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to . * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bug #11659). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most distributions/people use) it never worked correctly. ] Thanks to Remy LABENE for help with debugging the problem.

As part of our efforts to get the Cavium OCTEON processor support merged (see: http://marc.info/?l=linux-mips&m=122704699515601), we have this CF driver for your consideration. Most OCTEON variants have *no* DMA or interrupt support on the CF interface so for these, only PIO is supported. Although if DMA is available, we do take advantage of it. The register definitions are part of the chip support patch set mentioned above, and are not included here. At this point I would like to get feedback on the patch and would expect that it would merge via the linux-mips tree along with the rest of the chip support.

PATA timeouts on old thinkpad

unexpected downspeed of AHCI controller on Intel Seaburg 5400

2008-11-18T20:44:23

[prior incomplete message was sent accidently] Have a relatively recent HP DL160 G5 incorporating the Seaburg 5400 chipset. Appears the 5400 is a MCM including a 631xESB/632xESB I/O controller. Running kernel 2.6.27.1. Latest HP BIOS. Strangely the SATA controller seems to be reporting that it can only run at 1.5 Gbps instead of 3 Gbps. ahci 0000:00:1f.2: version 3.0 ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) -> IRQ 19 ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 6 ports 1.5 Gbps 0x3f impl SATA mode ahci 0000:00:1f.2: flags: 64bit ncq pm led slum part ahci 0000:00:1f.2: setting latency timer to 64 Looked at the AHCI specification and Intel datasheets for both the 5400 and the 631xESB/632xESB. The latter shows the register but does not include 3 Gpbs in the enumeration. SATA-II support is stated in general for the device however. The SATA links all are reported as running at 1.5 Gbps. Definitely did pull the rate-limit jumpers off the Seagate ES.2 drives. details: http://binnacle.cx/f
