2006-12-01[PATCH] sata_promise fixes and updatesMikael Pettersson1-11/+21
This patch updates the sata_promise driver as follows: - Correct typo in definition of PDC_TBG_MODE: it's at 0x41C not 0x41 in first-generation chips. This error caused PCI access alignment exceptions on SPARC64, and on all platforms it disabled the expected initialisation of TBG mode. - Add flags field to struct pdc_host_priv. Define PDC_FLAG_GEN_II and use it to distinguish first- and second-generation chips. - Prevent the FLASH_CTL FIFO_SHD bit from being set to 1 on second- generation chips. This matches Promises' ulsata2 driver. - Prevent TBG mode and SLEW rate initialisation in second-generation chips. These two registers have moved, TBG mode has been redefined, and Promise's ulsata2 driver no longer attempts to initialise them. - Correct PCI device table so devices 0x3570, 0x3571, and 0x3d73 are marked as 2057x (2nd gen) not 2037x (1st gen). - Correct PCI device table so device 0x3d17 is marked as 40518 (2nd gen 4 ports) not 20319 (1st gen 4 ports). - Correct pdc_ata_init_one() to treat 20771 as a second-generation chip. Tested on 0x3d75 (2nd gen), 0x3d73 (2nd gen), and 0x3373 (1st gen) chips. The information comes from the newly uploaded Promise SATA HW specs, Promise's ultra and ulsata2 drivers, and debugging on 3d75/3d73/3373 chips. hp->hotplug_offset could now be removed and its value recomputed in pdc_host_init() using hp->flags, but that would be a cleanup not a functional change, so I'm ignoring it for now.

2006-12-01[PATCH] libata: sync result_tf.flags w/ command tf.flagsTejun Heo1-3/+11
libata didn't initialize result_tf.flags which indicates transfer type (RW/FUA) and address type (CHS/LBA/LBA48). ata_gen_fixed_sense() assumed result_tf.flags equals command tf.flags and failed to report the first failed block to SCSI layer because zero tf flags indicates CHS and bad block reporting for CHS is not implemented.

2006-12-01[PATCH] ata_piix: apply device detection via polling IDENTIFYTejun Heo1-98/+6
PATA PIIX uses reset signature + TF r/w test for device presence detection, which doesn't always work. It sometimes reports phantom device which results in IDENTIFY timeouts. SATA PIIX uses some combination of PCS + reset signature + TF r/w test for device presence detection. No combination satifies all and for some controllers, there doesn't seem to be any combination which works reliably. This patch makes both PATA and SATA piix's use reset signature + TF r/w + polling IDENTIFY for device detection. This is what the old libata (before irq-pio and new EH) did and what IDE does. This patch also removes now obsolete PIIX_FLAG_IGNORE_PCS, force_pcs and related code. Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-01[PATCH] libata: implement presence detection via polling IDENTIFYTejun Heo3-7/+37
On some controllers (ICHs in piix mode), there is *NO* reliable way to determine device presence other than issuing IDENTIFY and see how the transaction proceeds by watching the TF status register. libata acted this way before irq-pio and phantom devices caused very little problem but now that IDENTIFY is performed using IRQ drive PIO, such phantom devices now result in multiple 30sec timeouts during boot. This patch implements ATA_FLAG_DETECT_POLLING. If a LLD sets this flag, libata core issues the initial IDENTIFY in polling mode and if the initial data transfer fails w/ HSM violation, the port is considered to be empty thus replicating the old libata and IDE behavior.

2006-12-01[PATCH] libata: use FLUSH_EXT only when driver is larger than LBA28 limitTejun Heo2-3/+6
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 Heo1-28/+67
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.

2006-12-01[PATCH] libata: implement ATA_EHI_SETMODE and ATA_EHI_POST_SETMODETejun Heo2-2/+14
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: handle 0xff status properlyTejun Heo1-12/+18
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 Heo1-5/+22
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>

2006-11-22WorkStruct: Pass the work_struct pointer instead of context dataDavid Howells3-17/+21
Pass the work_struct pointer to the work function rather than context data. The work function can use container_of() to work out the data. For the cases where the container of the work_struct may go away the moment the pending bit is cleared, it is made possible to defer the release of the structure by deferring the clearing of the pending bit. To make this work, an extra flag is introduced into the management side of the work_struct. This governs auto-release of the structure upon execution. Ordinarily, the work queue executor would release the work_struct for further scheduling or deallocation by clearing the pending bit prior to jumping to the work function. This means that, unless the driver makes some guarantee itself that the work_struct won't go away, the work function may not access anything else in the work_struct or its container lest they be deallocated.. This is a problem if the auxiliary data is taken away (as done by the last patch). However, if the pending bit is *not* cleared before jumping to the work function, then the work function *may* access the work_struct and its container with no problems. But then the work function must itself release the work_struct by calling work_release(). In most cases, automatic release is fine, so this is the default. Special initiators exist for the non-auto-release case (ending in _NAR). Signed-Off-By: David Howells <dhowells@redhat.com>
2006-11-22WorkStruct: Separate delayable and non-delayable events.David Howells2-8/+5
Separate delayable work items from non-delayable work items be splitting them into a separate structure (delayed_work), which incorporates a work_struct and the timer_list removed from work_struct. The work_struct struct is huge, and this limits it's usefulness. On a 64-bit architecture it's nearly 100 bytes in size. This reduces that by half for the non-delayable type of event.
