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().

ata_id_to_dma_mode() isn't quite generic. The function is basically privately implemented ata_id_xfermask() combined with hardcoded mode printing and configuration which are specific to ata_generic.

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. This change will make cable mis-detection and other initial configuration problems corrected before partition scanning code gives up.

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.

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.

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.

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.

Correct the decoding of negative C temperatures. The code did a binary OR of two bytes to make a 16 bit value, but assignd it to an integer.

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.

Prior to this patch, we ignored some port resources, which masked the it87 problem. Signed-off-by: NBjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: NMark M. Hoffman <mhoffman@lightlink.com>

The reporter of http://bugzilla.kernel.org/show_bug.cgi?id=9791 tracked it down to this commit and confirmed that reverting the patch restores the correct behaviour.
