2007-04-04[PATCH] libata: add NCQ blacklist entries from Silicon Image Windows driver (v2)Robert Hancock
This adds some NCQ blacklist entries taken from the Silicon Image 3124/3132 Windows driver .inf files. There are some confirming reports of problems with these drives under Linux (for example http://lkml.org/lkml/2007/3/4/178) so let's disable NCQ on these drives. [ I'm personally starting to wonder whether we shouldn't disable NCQ by default, and perhaps have a white-list. There seems to be a *lot* of drives that do this wrong.. - Linus ] Signed-off-by: Robert Hancock <hancockr@shaw.ca> Acked-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-04-042.6.21 fix lba48 bug in libata fill_result_tf()Mark Lord
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().

2007-03-28libata: IDENTIFY backwards for drive side cable detectionTejun Heo
For drive side cable detection to work correctly, drives need to be identified backwards such that the slave device releases PDIAG- before the mater drive tries to detect cable type. ata_bus_probe() was fixed by commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c but the new EH path wasn't fixed. This patch makes new EH path do IDENTIFY backwards. ata_dev_configure() for new devices are still performed master first. This is to keep the detection messages in forward order.

2007-03-28ahci.c: walkaround for SB600 SATA internal error issueConke Hu
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>

2007-03-09sata_nv: revert use of notifiers for nowRobert Hancock
Commit 721449bf0d51213fe3abf0ac3e3561ef9ea7827a added support for using the ADMA notifier bits to determine which commands to check for completion. However there have been reports that this causes command timeouts in certain cases. This is still being investigated. In addition, apparently the notifiers won't work if ADMA is disabled on the other port as a result of an ATAPI device being connected, and we don't handle this case properly. For now, just restore the previous behavior of checking all active commands to see if they are complete, without relying on the notifiers.

2007-03-09Fix simplex adapters with libataPetr Vandrovec
Recently I got my hands on nVidia's MCP61 PM-AM board, and it contains IDE chip configured by BIOS with only primary channel enabled. This confuses code which probes for device DMA capabilities - it gets 0x60 (happy duplex device) from primary channel BMDMA, but 0xFF (nobody here) from secondary channel BMDMA. Due to this code then believes that chip is simplex. I do not address this problem in my patch, as I'm not sure how to handle this. Probably ata_pci_init_one should have bitmap of enabled/possible interfaces instead of their count, but it looks like quite intrusive change, and maybe we do not care - for device with only one channel simplex and regular DMA engines are same. But making device simplex pointed out that support for DMA on simplex devices is currently broken - ata_dev_xfermask tests whether device is simplex and if it is whether DMA engine was assigned to this port. If not then it strips out DMA bits from device. Problem is that code which assigns DMA engine to port in ata_set_mode first detect device mode and assigns DMA engine to channel only if some DMA capable device was found. And as xfermask stripped out DMA bits, host->simplex_claimed is always NULL with current implementation. By allowing DMA either if simplex_claimed is NULL or if it points to current port DMA can be finally used - it gets assigned to first port which contains any DMA capable device.

2007-03-06pata_legacy: fix io/irq mismatchMikael Pettersson
pata_legacy fails to detect the disk on my old ISA/VLB 486: it starts to probe io=0x1f0 ctr=0x3f6 irq=15, complains loudly about IDENTIFYs timing out, and finally fails. (Sorry I couldn't capture the kernel's boot messages.) It turns out that the driver's mapping from io to irq in legacy_irq[] is wrong: index 0 for io=0x1f0 has irq=15 but should have irq=14, and index 1 for io=0x170 has irq=14 but should have irq=15. This is confirmed by a comparison with include/asm-i386/ide.h:ide_default_irq(). This patch swaps the first two elements in legacy_irq[], which makes pata_legacy work on my 486.
