* | sata_sil: add Large Block Transfer supportRobert Hancock2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for the Large Block Transfer feature found in Silicon Image 311x controllers. This allows transferring bigger contiguous chunks of data from system memory and avoids the 64KB boundary restriction of standard SFF controllers. This is based on a patch from Jeff Garzik (from the sii-lbt branch of libata-dev) but includes a few bug fixes: Since the bmdma2 register does not implement the status bits, the original bmdma register must be used except where the bmdma2 register is required. As well the DMA boundary should be 31-bit instead of 32-bit since the top bit of the length field is still required for the PRD end-of-table flag.

* | libata: perform port detach in EHTejun Heo2008-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | ata_port_detach() first made sure EH saw ATA_PFLAG_UNLOADING and then assumed EH context belongs to it and performed detach operation itself. However, UNLOADING doesn't disable all of EH and this could lead to problems including triggering WARN_ON()'s in EH path. This patch makes port detach behave more like other EH actions such that ata_port_detach() requests EH to detach and waits for completion.

Instead of adding another one with long name, do the following cleanup. * Implement and export ata_link_next() and ata_dev_next() which take @mode parameter and can be used to build custom loop. * Implement ata_for_each_link() and ata_for_each_dev() which take looping mode explicitly. The following iteration modes are implemented. * ATA_LITER_EDGE : loop over edge links * ATA_LITER_HOST_FIRST : loop over all links, host link first * ATA_LITER_PMP_FIRST : loop over all links, PMP links first * ATA_DITER_ENABLED : loop over enabled devices * ATA_DITER_ENABLED_REVERSE : loop over enabled devices in reverse order * ATA_DITER_ALL : loop over all devices * ATA_DITER_ALL_REVERSE : loop over all devices in reverse order This change removes exlicit device enabledness checks from many loops and makes it clear which ones are iterated over in which direction.

* ata_piix: add borked Tecra M4 to broken suspend listTejun Heo2008-12-01
| | | | | | | | | | | | | | | | Tecra M4 sometimes forget what it is and reports bogus data via DMI which makes the machine evade broken suspend matching and thus fail suspend/resume. This patch updates piix_broken_suspend() such that it can match such case. As the borked DMI data is a bit generic, matching many entries to make the match more specific is necessary. As the usual DMI matching is limited to four entries, this patch uses hard coded manual matching. This is reported by Alexandru Romanescu.

* libata: improve phantom device detectionTejun Heo2008-11-14
| | | | | | | | | | | | | | | | | | | | | | | Currently libata uses four methods to detect device presence. 1. PHY status if available. 2. TF register R/W test (only promotes presence, never demotes) 3. device signature after reset 4. IDENTIFY failure detection in SFF state machine Combination of the above works well in most cases but recently there have been a few reports where a phantom device causes unnecessary delay during probe. In both cases, PHY status wasn't available. In one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which didn't qualify as #4. The other failed #2 but as it passed #3 and #4, it still caused failure. In both cases, phantom device reported diagnostic failure, so these cases can be safely worked around by considering any !ATA_DRQ IDENTIFY failure as NODEV_HINT if diagnostic failure is set.

* libata: fix last_reset timestamp handlingTejun Heo2008-11-11
| | | | | | | | | | | | | | | | | | | ehc->last_reset is used to ensure that resets are not issued too close to each other. It's initialized to jiffies minus one minute on EH entry. However, when new links are initialized after PMP is probed, new links have zero for this timestamp resulting in long wait depending on the current jiffies. This patch makes last_set considered iff ATA_EHI_DID_RESET is set, in which case last_reset is always initialized. As an added precaution, WARN_ON() is added so that warning is printed if last_reset is in future. This problem is spotted and debugged by Shane Huang.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reverts the following three commits which convert libata to use block layer tagging. 43a49cbdf31e812c0d8f553d433b09b421f5d52c e013e13bf605b9e6b702adffbe2853cfc60e7806 2fca5ccf97d2c28bcfce44f5b07d85e74e3cd18e Although using block layer tagging is the right direction, due to the tight coupling among tag number, data structure allocation and hardware command slot allocation, libata doesn't work correctly with the current conversion. The biggest problem is guaranteeing that tag 0 is always used for non-NCQ commands. Due to the way blk-tag is implemented and how SCSI starts and finishes requests, such guarantee can't be made. I'm not sure whether this would actually break any low level driver but it doesn't look like a good idea to break such assumption given the frailty of ATA controllers. So, for the time being, keep using the old dumb in-libata qc allocation.

| | | | | | | | | | | | | | | | | | | | | | | All three flavors of sata_nv's are different in how their hardreset behaves. * generic: Hardreset is not reliable. Link often doesn't come online after hardreset. * nf2/3: A little bit better - link comes online with longer debounce timing. However, nf2/3 can't reliable wait for the first D2H Register FIS, so it can't wait for device readiness or classify the device after hardreset. Follow-up SRST required. * ck804: Hardreset finally works.

* sata_promise: add ATA engine reset to reset opsMikael Pettersson2008-11-04
| | | | | | | | | | | | | | | | | | | | Promise ATA engines need to be reset when errors occur. That's currently done for errors detected by sata_promise itself, but it's not done for errors like timeouts detected outside of the low-level driver. The effect of this omission is that a timeout tends to result in a sequence of failed COMRESETs after which libata EH gives up and disables the port. At that point the port's ATA engine hangs and even reloading the driver will not resume it. To fix this, make sata_promise override ->hardreset on SATA ports with code which calls pdc_reset_port() on the port in question before calling libata's hardreset. PATA ports don't use ->hardreset, so for those we override ->softreset instead. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* sata_via: fix support for 5287Tejun Heo2008-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5287 used to be treated as vt6420 but it didn't work. It's new family of controllers called vt8251 which hosts four SATA ports as M/S of the two ATA ports. This configuration is rather peculiar in that although the M/S devices are on the same port, each have its own SCR (or equivalent link status/control) registers which screws up the port-link-device hierarchy assumed by libata. Another controller which falls into this category is ata_piix w/ SIDPR access. libata now has facility to deal with this class of controllers named slave_link. A low level driver for such controllers can just call ata_slave_link_init() on the respective ports and libata will handle all the difficult parts like following up with single SRST after hardresetting both ports. This patch creates new controller class vt8251, implements slave_link aware init sequence and config space based SCR access for it and moves 5287 to the new class. This patch is based on Joseph Chan's larger patch which was created before slave_link was implemented in libata. http://thread.gmane.org/gmane.linux.kernel.commits.mm/40640 Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Joseph Chan <JosephChan@via.com.tw> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | In ata_tf_to_lba48(), when evaluating (tf->hob_lbal & 0xff) << 24 the expression is promoted to signed int (since int can hold all values of u8). However, if hob_lbal is 128 or more, then it is treated as a negative signed value and sign-extended when promoted to u64 to | into sectors, which leads to the MSB 32 bits of section getting set incorrectly.

| * libata: clear saved xfer_mode and ncq_enabled on device detachTejun Heo2008-10-27
| | | | | | | | | | | | | | | | | | | | libata EH saves xfer_mode and ncq_enabled at start to later set DUBIOUS_XFER flag if it has changed. These values need to be cleared on device detach such that hot device swap doesn't accidentally miss DUBIOUS_XFER.

| * sata_sil24: configure max read request size to 4kTejun Heo2008-10-27
| | | | | | | | | | | | | | | | | | | | | | | | Due to request posting limitations, bandwidth of sil3132 is limited to around 120MB/s with the minimum pci-e payload size (128bytes) which is used by most consumer systems. However, write throughput can be slightly (~3%) increased by increasing the max read requeset size. Configure it to 4k which is the maximum supported. This optimization is also done by SIMG's windows driver. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| * ahci: Add support for Promise PDC42819Mark Nelson2008-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an appropriate entry for the Promise PDC42819 controller. It has an AHCI mode and so far works correctly with board_ahci. This chip is found on Promise's FastTrak TX2650 (2 port) and TX4650 (4 port) software-based RAID cards (for which there is a binary driver, t3sas) and can be found on some motherboards, for example the MSI K9A2 Platinum, which calls the chip a Promise T3 controller. Although this controller also supports SAS devices, its default bootup mode is AHCI and the binary driver has to do some magic to get the chip into the appropriate mode to drive SAS disks. Seeing as no documentation is provided by Promise, adding this entry to the ahci driver allows the controller to be useful to people as a SATA controller (with no ill effects on the system if a SAS disk is connected - probing of the port just times out with "link online but device misclassified"), without having to resort to using the binary driver. Users who require SAS or the proprietary software raid can get this functionality using the binary driver.
