2006-12-01[PATCH] libata: convert @post_reset to @flags in ata_dev_read_id()Tejun Heo
Make ata_dev_read_id() take @flags instead of @post_reset. Currently there is only one flag defined - ATA_READID_POSTRESET, which is equivalent to @post_reset. This is preparation for polling presence detection. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-12-01[PATCH] libata: use FLUSH_EXT only when driver is larger than LBA28 limitTejun Heo
Many drives support LBA48 even when its capacity is smaller than 1<<28, as LBA48 is required for many functionalities. FLUSH_EXT is mandatory for drives w/ LBA48 support. Interestingly, at least one of such drives (ST960812A) has problems dealing with FLUSH_EXT. It eventually completes the command but takes around 7 seconds to finish in many cases thus drastically slowing down IO transactions. This seems to be a firmware bug which sneaked into production probably because no other ATA driver including linux IDE issues FLUSH_EXT to drives which report support for LBA48 & FLUSH_EXT but is smaller than 1<<28 blocks. This patch adds ATA_DFLAG_FLUSH_EXT which is set iff the drive supports LBA48 & FLUSH_EXT and is larger than LBA28 limit. Both cache flush paths are updated to issue FLUSH_EXT only when the flag is set. Note that the changed behavior is more inline with the rest of libata. libata prefers shorter commands whenever possible.

2006-12-01[PATCH] ahci: honor PORTS_IMPL on ICH8sTejun Heo
Some ICH8s use non-linear port mapping. ahci driver didn't use to honor PORTS_IMPL and this made ports after hole nonfunctional. This patch makes ahci mark those ports as dummy and properly initialize all the implemented ports after the dummies. As it's unknown whether other AHCIs implement PORTS_IMPL register properly, new board id board_ahci_pi is added and selectively applied to ICH8s. All other AHCIs continue to use linear mapping regardless of PORTS_IMPL value. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Robin H.

2006-12-01[PATCH] libata: implement ATA_EHI_SETMODE and ATA_EHI_POST_SETMODETejun Heo
libata EH used to perform ata_set_mode() iff the EH session performed reset as indicated by ATA_EHI_DID_RESET. This is incorrect because ->dev_config() called by revalidation is allowed to modify transfer mode which ata_set_mode() should take care of. This patch implements the following two flags. * ATA_EHI_SETMODE: set during EH to schedule ata_set_mode(). Both new device attachment and revalidation set this flag. * ATA_EHI_POST_SETMODE: set while the device is revalidated after ata_set_mode(). Post-setmode revalidation is different from initial configuaration and EH revalidation in that ->dev_config() is not allowed tune transfer mode. LLD can use this flag to determine whether it's allowed to tune transfer mode. Note that POST_SETMODE ->dev_config() is guaranteed to be preceded by non-POST_SETMODE ->dev_config().

2006-12-01[PATCH] libata: implement ATA_EHI_PRINTINFOTejun Heo
Implement ehi flag ATA_EHI_PRINTINFO. This flag is set when device configuration needs to print out device info. This used to be handled by @print_info argument to ata_dev_configure() but LLDs also need to know about it in ->dev_config() callback. This patch replaces @print_info w/ ATA_EHI_PRINTINFO and make sata_sil print workaround messages only on the initial configuration.

2006-12-01[PATCH] libata: handle 0xff status properlyTejun Heo
libata waits for !BSY even when the status register reports 0xff. This causes long boot delays when D8 isn't pulled down properly. This patch does the followings. * don't wait if status register is 0xff in all wait functions * make ata_busy_sleep() return 0 on success and -errno on failure. -ENODEV is returned on 0xff status and -EBUSY on other failures. * make ata_bus_softreset() succeed on 0xff status. 0xff status is not reset failure. It indicates no device. This removes unnecessary retries on such ports. Note that the code change assumes unoccupied port reporting 0xff status does not produce valid device signature.

2006-11-29[PATCH] ahci: ignore PORT_IRQ_IF_ERR on JMB controllersTejun Heo
JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The IRQ status bit indicates interface error or protocol mismatch and ahci driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI device raises check condition, ahci interprets it as ATA bus error and thus resets it which, in turn, raises check condition thus creating a reset loop and rendering the device unuseable. This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when interpreting error condition. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Justin Tsai <justin@jmicron.com>

2006-11-14[PATCH] libata: Convert from module_init to subsys_initcallBrian King
When building a monolithic kernel, the load order of drivers does not work for SAS libata users, resulting in a kernel oops. Convert libata to use subsys_initcall instead of module_init, which ensures that libata gets loaded before any LLDD. This is the same thing that scsi core does to solve the problem. The load order problem was observed on ipr SAS adapters and should exist for other SAS users as well.

2006-11-14libata: fix double-completion on errorDarrick J. Wong
A curious thing happens, however, when ata_qc_new_init fails to get an ata_queued_cmd: First, ata_qc_new_init handles the failure like this: cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1); done(cmd); Then, we return to ata_scsi_translate and do this: err_mem: cmd->result = (DID_ERROR << 16); done(cmd); It appears to me that first we set a status code indicating that we're ok but the device queue is full and finish the command, but then we blow away that status code and replace it with an error flag and finish the command a second time! That does not seem to be desirable behavior since we merely want the I/O to wait until a command slot frees up, not send errors up the block layer. In the err_mem case, we should simply exit out of ata_scsi_translate instead. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
