2006-04-10[PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig1-1/+0
Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

2006-03-31[PATCH] ata_piix: fix ich6/m_map_dbTejun Heo1-2/+2
MAP tables of ich6 and ich6m are wrong. Depending on port usage, ata_piix may fail to initialize attached devices. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-03-21[SCSI] libata: implement minimal transport template for ->eh_timed_outTejun Heo1-1/+0
SCSI midlayer has moved hostt->eh_timed_out to transport template. As libata doesn't need full-blown transport support yet, implement minimal transport for libata. No transport class or whatsoever, just empty transport template with ->eh_timed_out hook. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-03-03[PATCH] ata_piix: reimplement piix_sata_probe()Tejun Heo1-23/+38
Reimplement piix_sata_probe() such that it turns on PCS enable bits on all avaliable ports and check present bits after a while to determine device presence. This should help broken BIOSes. After device presence detection is complete, PCS enable bits of unoccupied bits are turned off unless the controller supports AHCI (ICH6/7 docs mandate all enables bits are always set on AHCI capable controllers). Note that PCS present bits are ignored on 6300ESB as described in the datasheet. This should fix device detection problems reported with the controller.

2006-03-03[PATCH] ata_piix: implement proper port mapTejun Heo1-60/+122

2006-01-28[libata ata_piix] Fix ICH6/7 map value interpretationJeff Garzik1-1/+1
The previous change failed to properly mask out unrelated bits, which resulted in a failure to detect devices.
2006-01-26[PATCH] ata_piix: fix MAP VALUE interpretation for for ICH6/7Tejun Heo1-14/+39
Unlike their older siblings, ICH6 and 7 use different scheme for MAP VALUE. This patch makes ata_piix interpret MV properly on ICH6/7. Pre-ICH6/7 The value of these bits indicate the address range the SATA port responds to, and whether or not the SATA and IDE functions are combined. 000 = Non-combined. P0 is primary master. P1 is secondary master. 001 = Non-combined. P0 is secondary master. P1 is primary master. 100 = Combined. P0 is primary master. P1 is primary slave. P-ATA is 2:0 Map Value secondary. 101 = Combined. P0 is primary slave. P1 is primary master. P-ATA is secondary. 110 = Combined. P-ATA is primary. P0 is secondary master. P1 is secondary slave. 111 = Combined. P-ATA is primary. P0 is secondary slave. P1 is secondary master. ICH6/7 Map Value - R/W. Map Value (MV): The value in the bits below indicate the address range the SATA ports responds to, and whether or not the PATA and SATA functions are combined. When in combined mode, the AHCI memory space is not available and AHCI may not be used. 00 = Non-combined. P0 is primary master, P2 is the primary slave. P1 is secondary master, P3 is the 1:0 secondary slave (desktop only). P0 is primary master, P2 is the primary slave (mobile only). 01 = Combined. IDE is primary. P1 is secondary master, P3 is the secondary slave. (desktop only) 10 = Combined. P0 is primary master. P2 is primary slave. IDE is secondary 11 = Reserved Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, without this patch, ata_piix misdetects my ICH7's combined mode, ending up not applying bridge limits to PX-710SA and configuring IDE drive on 40-c cable to UDMA/66.

2006-01-06[PATCH] Suspend support for libataJens Axboe1-0/+4
This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.

2005-09-08[PATCH] scan all enabled ports on ata_piixHannes Reinecke1-4/+6
ICH6 spec defines the PORT_ bits as: PORT_ENABLED (R/W): 0 = Disabled. The port is in the off state and cannot detect any devices. 1 = Enabled. The port can transition between the on, partial, and slumber states and can detect devices. PORT_PRESENT (R/O) The status of this bit may change at any time. This bit is cleared when the port is disabled via PORT_ENABLED. This bit is not cleared upon surprise removal of a device. So from a textual view it is not necessary that PORT_PRESENT _must_ be set, especially if a device detection has to be done anyway. And, in fact, this is the view that ACER has been taken with its new Laptops (e.g. Travelmate 4150). And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.

2005-07-28libata: Check PCI sub-class code before disabling AHCIGreg Felix1-6/+13
This patch adds functionality to check the PCI sub-class code of an AHCI capable device before disabling AHCI. It fixes a bug where an ICH7 sata controller is being setup by the BIOS as sub-class 1 (ide) and the AHCI control registers weren't being initialized, thus causing an IO error in piix_disable_ahci().

2005-05-26libata: Fix use-after-iounmapJeff Garzik1-0/+2
Jens Axboe pointed out that the iounmap() call in libata was occurring too early, and some drivers (ahci, probably others) were using ioremap'd memory after it had been unmapped. The patch should address that problem by way of improving the libata driver API: * move ->host_stop() call after all ->port_stop() calls have occurred. * create default helper function ata_host_stop(), and move iounmap() call there. * add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark). sata_qstor appears to require the host-stop-before-port-stop ordering that existed prior to applying the attached patch.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
