* [PATCH] libata: rework legacy handling to remove much of the cruftAlan Cox2006-08-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kill host_set->next Fix simplex support Allow per platform setting of IDE legacy bases Some of this can be tidied further later on, in particular all the legacy port gunge belongs as a PCI quirk/PCI header decode to understand the special legacy IDE rules in the PCI spec. Longer term Jeff also wants to move the request_irq/free_irq out of core which will make this even cleaner. tj: folded in three followup patches - ata_piix-fix, broken-arch-fix and fix-new-legacy-handling, and separated per-dev xfermask into separate patch preceding this one. Folded in fixes are... * ata_piix-fix: fix build failure due to host_set->next removal * broken-arch-fix: add missing include/asm-*/libata-portmap.h * fix-new-legacy-handling: * In ata_pci_init_legacy_port(), probe_num was incorrectly incremented during initialization of the secondary port and probe_ent->n_ports was incorrectly fixed to 1. * Both legacy ports ended up having the same hard_port_no. * When printing port information, both legacy ports printed the first irq.

* [libata] ata_piix: Consolidate PCS register writingJeff Garzik2006-07-161-25/+28
| | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch, the driver would do this for each port: read 8-bit PCS write 8-bit PCS read 8-bit PCS write 8-bit PCS In the field, flaky behavior has been observed related to this register. In particular, these overzealous register writes can cause misdetection problems. Update to do the following once (not once per port) at boot: read 16-bit PCS if needs changing, write 16-bit PCS And thereafter, we only perform a 'read 16-bit PCS' per port. This should eliminate all PCS writes in many cases, and be more friendly in the cases where we do need to enable ports. Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] ata_piix: reimplement piix_sata_probe()Tejun Heo2006-03-031-23/+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.

* [PATCH] ata_piix: fix MAP VALUE interpretation for for ICH6/7Tejun Heo2006-01-261-14/+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.

|/ | | | | | | | | | | | | | | | 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.
