2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok9-60/+31
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

2007-07-10pata_hpt3x3: major reworking and testingAlan Cox2-15/+85
The HPT343/345 (aka 363) is a bit of a warped device. For many setups you need to access the other registers via BAR4 offsets. PIO is now rock solid, DMA isn't. Unfortunately the drivers/ide hpt34x driver is completely broken so doesn't help further debug.

2007-07-10libata: clean up horkage handlingTejun Heo1-5/+8
Horkage handling had the following problems. * dev->horkage was positioned after ATA_DEVICE_CLEAR_OFFSET, so it was cleared before the device is configured. This broke HORKAGE_DIAGNOSTIC. * Some used dev->horkage while others called ata_device_blacklisted() directly. This was at best confusing. This patch moves dev->horkage right after dev->flags and set the field according to the blacklist during device configuration. All users test against dev->horkage. ata_device_blacklisted() now has only one user, make it static. While at it, rename it to ata_dev_blacklisted() for consistency.

2007-07-10libata: simplify PCI legacy SFF host handlingTejun Heo6-262/+38
With PCI resource fix up for legacy hosts. We can use the same code path to allocate IO resources and initialize host for both legacy and native SFF hosts. Only IRQ requesting needs to be different. Rename ata_pci_*_native_host() to ata_pci_*_sff_host(), kill all legacy specific functions and use the renamed functions instead. This simplifies code a lot.

2007-07-10sata_promise: SATA hotplug support, take 2Mikael Pettersson1-5/+36
This patch enables hotplugging of SATA devices in the sata_promise driver. It's been tested successfully on both first- and second-generation Promise SATA chips: SATA150 TX2plus, SATAII150 TX2plus, SATAII150 TX4, SATA300 TX2plus, and SATA300 TX4. The only quirk I've seen is that hotplugging (insertion) on the first-generation SATA150 TX2plus requires a lengthier EH sequence than on the second-generation chips. On the second-generation chips a simple soft reset seems to suffice, but on the first-generation chip there's a "port is slow to respond" after the initial soft reset, after which libata issues a hard reset, and then the device is recognised. The hotplug checks are high up in the interrupt handling path, not deep down in error_intr as in ahci/sata_sil24. That's because the chip doesn't signal hotplug status changes in the per-port status register: instead a global register contains hotplug control and status flags for all ports. I considered following the ahci/sata_sil24 structure, but that would have required non-trivial changes to the interrupt handling path, so I chose to keep the hotplug changes simple and unobtrusive. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> -- This patch depends on the "sata_promise: cleanups" patch. Changes since the previous version (posted June 19): - Correct pdc_interrupt() to increment 'handled' also in the hotplug case. This prevents IRQ_NONE from being returned when an interrupt only has hotplug events to handle, which could confuse the kernel's IRQ machinery. - Added testing on the SATAII150 TX4. drivers/ata/sata_promise.c | 41 ++++++++++++++++++++++++++++++++++++----- 1 files changed, 36 insertions(+), 5 deletions(-) Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-07-09[libata] AHCI: Add support for Marvell AHCI-like chips (initially 6145)Jeff Garzik1-3/+48
Add support for the SATA portion of Marvell's AHCI-compatible chips. The PATA port capability, also available via AHCI, is disabled until support is completed. NCQ and PCI MSI are disabled by default. Marvell says "we use NCQ" in their drivers but "we do not use PCI MSI." Theoretically that implies we need to fix ahci.c to work with Marvell NCQ, but one wonders why Marvell NCQ is any different from other AHCI chips. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-07-09sata_sil24: sil24_interrupt() micro-optimisationMikael Pettersson1-1/+1
sil24_interrupt() loads host->ports[i] into a local variable, validates it, and then loads the value again in the call to sil24_host_intr(). This patch replaces the second load by a reference to the local variable. This is safe since no side-effects have occurred since the initial load. It also improves readability since it makes it clear that the parameter to sil24_host_intr() is the same value which was just validated.
