2009-02-06md: Fix a bug in linear.c causing which_dev() to return the wrong device.Andre Noll
ab5bd5cbc8d4b868378d062eed3d4240930fbb86 introduced the following bug in linear software raid for large arrays on 32 bit machines: which_dev() computes the device holding a given sector by shifting down the sector number to a 32 bit range, dividing by the array spacing and looking up the resulting index in the hash table of the array. Because the computed index might be slightly too small, a loop at the end of which_dev() increases the index until the given sector actually falls into the range of the device associated with that index. The changes of the above mentioned commit caused this loop to check whether the _index_ rather than the sector number is small enough, effectively bypassing the loop and thus possibly returning the wrong device. As reported by Simon Kirby, this leads to errors such as linear_make_request: Sector 2340486136 out of bounds on dev sdi: 156301312 sectors, offset 2109870464 Fix this bug by introducing a local variable for the index so that the variable containing the passed sector is left unchanged.

2009-02-06md: Allow read error in a single drive raid1 to be passed up.NeilBrown
If a raid1 only has a single working device and gets a read error, we choose to simply return that error up to the filesystem (or whatever) rather than failing the whole array. However the codes doesn't quite do that. We attempt a readbalance which allocates the same drive, so we retry the read - indefinitely. Instead: If read_balance in the error case chooses the same drive that just failed, treat it as a failure and don't retry. Signed-off-by: NeilBrown <neilb@suse.de>

This patch adds a few device ID's. It also removes an ID that was used in an internal engineering version of a device and will never see commercial light. Even if this ID will be 'recycled' in the future, which is very unlikely, we don't know what kind of device will be behind it. Therefore it's safer to remove it.

2009-02-02libata: implement HORKAGE_1_5_GBPS and apply it to WD My BookTejun Heo
3Gbps is often much more prone to transmission failures. It's usually okay to let EH handle speed down after transmission failures but some WD My Book drives completely shutdown after certain transmission failures and after it only power cycling can revive them. Combined with the fact that external drives often end up with cable assembly which is longer than usual and more likely to have intervening gender, this makes these drives very likely to shutdown under certain configurations virtually rendering them unusable. This patch implements HOARKGE_1_5_GBPS and applies it to WD My Book such that 1.5Gbps is forced once the device is identified. Please take a look at the following bz for related reports. http://bugzilla.kernel.org/show_bug.cgi?id=9913 Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-02-02libata: add no penalty retry request for EH device handling routinesTejun Heo
Let -EAGAIN from EH device handling routines trigger EH retry without consuming its tries count. This will be used to implement link SPD horkage which requires hardreset to adjust SPD without affecting other EH decisions. As it bypasses the forward progress guarantee provided by the tries count, the requester is responsible for ensuring forward progress.

2009-02-02libata: improve probe failure handlingTejun Heo
When link is flaky at high speed, it isn't uncommon for a device to repeatedly fail probing sequence early after successfully negotiating high link speed. This often leads to consecutive hotplug events without successful probing. This patch improves libata EH such that it remembers probing trials and if there have been more than two unsuccessful trials in the past 60 seconds, slows down link speed to 1.5Gbps. As link speed negotiation is the duty of the PHY layer proper, the goal of this fallback mechanism is to provide the last resort when everything else fails, which unfortunately happens not too infrequently, so no fancy 6->3->1.5 speeding down or highest successful transmission speed seen kind of logics (yet).

2009-02-02libata: clear dev->ering in smarter wayTejun Heo
dev->ering used to be cleared together with the rest of ata_device in ata_dev_init() which is called whenever a probing event occurs. dev->ering is about to be used to track probing failures so it needs to remain persistent over multiple porbing events. This patch achieves this by doing the following. * Instead of CLEAR_OFFSET, define CLEAR_BEGIN and CLEAR_END and only clear between BEGIN and END. ering is moved after END. The split of persistent area is to allow hotter items remain at the head. * ering is explicitly cleared on ata_dev_disable() and when device attach succeeds. So, ering is persistent throug a device's life time (unless explicitly cleared of course) and also through periods inbetween disablement of an attached device and successful detection of the next one.

2009-02-02libata: fix EH device failure handlingTejun Heo
The dev->pio_mode > XFER_PIO_0 test is there to avoid unnecessary speed down warning messages but it accidentally disabled SATA link spd down during configuration phase after reset where PIO mode is always zero. This patch fixes the problem by moving the test where it belongs. This makes libata probing sequence behave better when the connection is flaky at higher link speeds which isn't too uncommon for eSATA devices.

However, if we do happen to be interrupted while we're not attached to a driver, we really shouldn't oops.

This is a port of libata's pata_cs5536.c (written by Martin K. Petersen) to IDE subsystem. Changes done while at it: * Reprogram PIO/MWDMA timings if needed before and after DMA transfer (chipset uses shared PIO/MWDMA timings). * Fix cable detection to report 80-wires cable if BIOS set it for any device on a port (IDE core will do drive-side cable detection later). * Don't disable UDMA while programming PIO timings. * Simplify PCI/MSR support. Pros of having IDE host driver in addition to libata's one: * IDE is much lighter than SCSI+libata, the host driver itself is also a bit smaller: text data bss dec hex filename 1261 496 4 1761 6e1 drivers/ata/pata_cs5536.o 1242 128 4 1374 55e drivers/ide/cs5536.o * This allows use of IDE features which are unavailable under libata. v2: * Fixes per review from Sergei: - simplify dependency check in Kconfig - use IDE_DRV_MASK also for ->drive_data - disable UDMA when programming MWDMA - program new DTC timings only when necessary - fix printk() level in cs5536_init_one() * Fix patch description according to comments from Alan and Sergei. v3: * Smarter masking of UDMA bits per Sergei's suggestion.
