2008-01-23libata: rename ATA_PROT_ATAPI_* to ATAPI_PROT_*Tejun Heo
ATA_PROT_ATAPI_* are ugly and naming schemes between ATA_PROT_* and ATA_PROT_ATAPI_* are inconsistent causing confusion. Rename them to ATAPI_PROT_* and make them consistent with ATA counterpart. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-01-23pata_amd: update mode selection for NV PATAsTejun Heo
Cable detection on NV PATA hosts isn't implemented and the CBLID- cable isn't wired according to the sepc either, so both host-side and generic drive-side cable detections are broken. Till now, nv_cable_detect() relied on peeking BIOS and ACPI configurations to upgrade to 80C but this often results in misdetection of 40C cable as 80C. Also, the original implementation was broken in that by the time BIOS configuration is read it has already been cleared by programming PIO0 during reset. This patch reimplements NV mode selection such that... * BIOS configuration value is stored during driver attach and restored on detach. * Cable type is fixed to ATA_CBL_PATA_IGN and mode selection is soley done by nv_mode_filter() which peeks both BIOS and ACPI configurations and filter accordingly.

2008-01-23libata: reimplement ata_acpi_cbl_80wire() using ata_acpi_gtm_xfermask()Tejun Heo
Reimplement ata_acpi_cbl_80wire() using ata_acpi_gtm_xfermask() and while at it relocate the function below ata_acpi_gtm_xfermask(). New ata_acpi_cbl_80wire() implementation takes @gtm, in both pata_via and pata_amd, use the initial GTM value. Both are trying to peek initial BIOS configuration, so using initial caching value makes sense. This fixes ACPI part of cable detection in pata_amd which previously always returned 0 because configuring PIO0 during reset clears DMA configuration.

2008-01-23libata: separate out ata_acpi_gtm_xfermask() from pacpi_discover_modes()Tejun Heo
Finding out matching transfer mode from ACPI GTM values is useful for other purposes too. Separate out the function and timing tables from pata_acpi::pacpi_discover_modes(). Other than checking shared-configuration bit after doing ata_acpi_gtm() in pacpi_discover_modes() which should be safe, this patch doesn't introduce any behavior change.

2008-01-23libata: add ATA_CBL_PATA_IGNTejun Heo
ATA_CBL_PATA_UNK indicates that the cable type can't be determined from the host side and might be either 80c or 40c. libata applies drive or other generic limit in this case. However, there are controllers where both host and drive side detections are misimplemented and the driver has to rely solely on private method - peeking BIOS or ACPI configuration or using some other private mechanism. This patch adds ATA_CBL_PATA_IGN which tells libata to ignore the cable type completely and just let the LLD determine the transfer mode via host transfer mode masks and ->mode_filter().

2008-01-23libata: implement fast speed down for unverified data transfer modeTejun Heo
It's very likely that the configured data transfer mode is the wrong one if device fails data transfers right after initial data transfer mode configuration (including NCQ on/off and xfermode). libata EH needs to speed down fast before upper layers give up on probing. This patch implement fast speed down rules to handle such cases better. Error occured while data transfer hasn't been verified trigger fast back-to-back speed down actions until data transfer works.

2008-01-23ahci: update PCS programmingTejun Heo
For intel ones, ahci unconditionally OR'd 0xf to PCS. This isn't correct for the following cases. * ich6/7m's which only implement P0 and P2 (0xf works fine tho) * ich8/9's which have six ports and needs 0x3f to enable all ports This patch updates PCS programming such that... * port_map determined by ahci_save_initial_config() is OR'd instead of 0xf * PCS is updated only if necessary (there are turned off enable bits) port_map is determined from PORTS_IMPL PCI register which is implemented as write or write-once register. If the register isn't programmed, ahci automatically generates it from number of ports, which is good enough for PCS programming. ICH6/7M are probably the only ones where non-contiguous enable bits are necessary && PORTS_IMPL isn't programmed properly but they're proven to work reliably with 0xf anyway.

2008-01-23libata: Disable ATA8-ACS proposed Trusted Computing features by defaultAlan Cox
Historically word 48 in the identify data was used to mean 32bit I/O was supported for VLB IDE etc. ATA8 reassigns this word to the Trusted Computing Group, where it is used for TCG features. This means that an ATA8 TCG drive is going to trigger 32bit I/O on some systems which will be funny. Anyway we need to sort this out ready for ATA8 so: - Reorder the ata.h header a bit so the ata_version function occurs early in it - Make dword_io check the ATA version - Add an ATA8 version checking TCG presence test While we are at it the current drafts have a flaw where it may not be possible to disable TCG features at boot (and opt out of the trusted model) as TCG intends because it relies on presence of a different optional feature (DCS). Handle this in software by refusing the TCG commands if libata.allow_tpm is not set. (We must make it possible as some environments such as proprietary VDR devices will doubtless want to use it to lock up content) Finally as with CPRM print a warning so that the user knows they may not be able to full access and use the device.

2008-01-22x86: GEODE fix a race condition in the MFGPT timer tickJordan Crouse
When we set the MFGPT timer tick, there is a chance that we'll immediately assert an event. If for some reason the IRQ routing for this clock has been setup for some other purpose, then we could end up firing an interrupt into the SMM handler or worse. This rearranges the timer tick init function to initalize the handler before we set up the MFGPT clock to make sure that even if we get an event, it will go to the handler. Furthermore, in the handler we need to make sure that we clear the event, even if the timer isn't running.

2008-01-22W1: w1_therm.c is flagging 0C etc as invalidDavid Fries
The extra rom[0] check is flagging valid temperatures as invalid when there is already a CRC data transmission check. w1_therm_read_bin() if (rom[8] == crc && rom[0]) verdict = 1; Requiring rom[0] to be non-zero will flag as invalid temperature conversions when the low byte is zero, specifically the temperatures 0C, 16C, 32C, 48C, -16C, -32C, and -48C. The CRC check is produced on the device for the previous 8 bytes and is required to ensure the data integrity in transmission. I don't see why the extra check for rom[0] being non-zero is in there. Evgeniy Polyakov didn't know either. Just for a check I unplugged the sensor, executed a temperature conversion, and read the results. The read was all ff's, which also failed the CRC, so it doesn't need to protect against a disconnected sensor. I have more extensive patches in the work, but these two trivial ones will do for today. I would like to hear from people who use the ds2490 USB to one wire dongle. 1 if you would be willing to test the patches as I currently only have the one sensor on a short parisite powered wire, 2 if there is any cheap sources for the ds2490.

2008-01-22hwmon: (it87) request only Environment Controller portsBjorn Helgaas
The IT8705F and related parts are Super I/O controllers that contain many separate devices. Some BIOSes describe IT8705F I/O port usage under a motherboard device (PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294. The it87 driver supports only the Environment Controller, which requires only two ISA ports, but it used to request an eight-port range. If that range exceeds a range reported by the BIOS, as 0x290-0x297 would, the request fails, and the it87 driver cannot claim the device. This patch makes the it87 driver request only the two ports used for the Environment Controller device.
