| * libata: handle broken cable reportingAlan Cox2007-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | One or two ancient drives predated the cable spec and didn't sent the valid bits for the field. I had hoped to leave this out of libata as a piece of historical annoyance but a recent CD drive shows the same bug so we have to import support for it. Same concept as Bartlomiej's changes old IDE except that as we have centralised blacklists we can avoid keeping another private table of stuff Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * libata and bogus LBA48 drivesGeert Uytterhoeven2007-11-04
| | | | | | | | | | | | | | | | | | | | | | | | A colleague noticed recent versions of Ubuntu no longer detect his 80 GB ST380020ACE drive. This drive is special in that it advertises LBA48 support, but has the lba_capacity_2 field set to zero (cfr. http://lkml.org/lkml/2004/3/30/163). Upon closer look, libata indeed doesn't seem to handle this case yet. Below is an (untested) fix. Signed-off-by: Jeff Garzik <jeff@garzik.org>

This reverts three changesets: 4be8f906435a6af241821ab5b94b2b12cb7d57d8 (PCI: disable MSI on RS690) aea6a433f50cd89b9cbd10850fd0b32f961f9883 (PCI: disable MSI on RD580) f122392f679ebed39db08074f935d770504623eb (PCI: disable MSI on RX790) This is based upon testing and feedback from Shane Huang <Shane.Huang@amd.com>.

| * | PCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.David Miller2007-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A reasonably common problem with some devices is that they will disable MSI generation when the INTX_DISABLE bit is set in the PCI_COMMAND register. Quirk this explicitly, guarding the pci_intx() calls in msi.c with this quirk indication. The first entries for this quirk are for 5714 and 5780 Tigon3 chips, and thus we can remove the workaround code from the tg3.c driver. Signed-off-by: David S.

An earlier commit to fix the problem: e3008dedff4bdc96a5f67224cd3d8d12237082a0: "PCI: disable MSI by default on systems with Serverworks HT1000 chips" was not entirely correct, and has been reverted. MSI does not work on the PCIX bus because the BIOS did not set the HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the bridge. We use the existing quirk_msi_ht_cap() to detect the problem and disable MSI in all buses behind it.

* | libata: increase 128 KB / cmd limit for ATAPI tape drivesTony Battersby2007-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

Combined with previous changes, this now makes device errors for all direct commands reported directly to the issuer without going through EH actions and reporting. Note that EH is still invoked after non-IO device errors to determine the nature of the error and resume command execution (some controller requires special care after error to continue). It just performs default maintenance after error, examines what's going on, realizes that it's none of its business and reports the command failure without logging any error messages.

First off, testing in Fedora has shown it to cause boot failures, bisected down by Martin Ebourne, and reported by Dave Jobes. So the commit will likely be reverted in the 2.6.23 stable kernels. Secondly, in the 2.6.24 model, x86-64 has now grown support for SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the bug is not visible any more, it's become invisible due to the code just being irrelevant and no longer enabled on the only architecture that this ever affected.

This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy.

| * | libata: implement ata_wait_after_reset()Tejun Heo2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On certain device/controller combination, 0xff status is asserted after reset and doesn't get cleared during 150ms post-reset wait. As 0xff status is interpreted as no device (for good reasons), this can lead to misdetection on such cases. This patch implements ata_wait_after_reset() which replaces the 150ms sleep and waits upto ATA_TMOUT_FF_WAIT if status is 0xff. ATA_TMOUT_FF_WAIT is currently 800ms which is enough for HHD424020F7SV00 to get detected but not enough for Quantum GoVault drive which is known to take upto 2s. Without parallel probing, spending 2s on 0xff port would incur too much delay on ata_piix's which use 0xff to indicate empty port and doesn't have SCR register, so GoVault needs to wait till parallel probing.

| * | libata: track SLEEP state and issue SRST to wake it upTejun Heo2007-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ATA devices in SLEEP mode don't respond to any commands. SRST is necessary to wake it up. Till now, when a command is issued to a device in SLEEP mode, the command times out, which makes EH reset the device and retry the command after that, causing a long delay. This patch makes libata track SLEEP state and issue SRST automatically if a command is about to be issued to a device in SLEEP.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the locking to work, only the tag map and tag bit map may be shared (incidentally, I was just explaining this to Nick yesterday, but I apparently didn't review the code well enough myself). But we also share the busy list! The busy_list must be queue private, or we need a block_queue_tag covering lock as well. So we have to move the busy_list to the queue. This'll work fine, and it'll actually also fix a problem with blk_queue_invalidate_tags() which will invalidate tags across all shared queues. This is a bit confusing, the low level driver should call it for each queue seperately since otherwise you cannot kill tags on just a single queue for eg a hard drive that stops responding. Since the function has no callers currently, it's not an issue. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of ptrdiff_t in places like - if (!access_ok(VERIFY_WRITE, u_tmp->rx_buf, u_tmp->len)) + if (!access_ok(VERIFY_WRITE, (u8 __user *) + (ptrdiff_t) u_tmp->rx_buf, + u_tmp->len)) is wrong; for one thing, it's a bad C (it's what uintptr_t is for; in general we are not even promised that ptrdiff_t is large enough to hold a pointer, just enough to hold a difference between two pointers within the same object). For another, it confuses the fsck out of sparse. Use unsigned long or uintptr_t instead. There are several places misusing ptrdiff_t; fixed.
