After reset completed, the scsi error handler sends out TEST_UNIT_READY to the device. For 'normal' devices the command will be handled by firmware. However, because the RAID console only interfaces to scsi mid layer, the firmware will not process the command for it. This will make the console to be offlined right after reset. Add the handling in driver to fix this problem. Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

During hard bus reset of st_shasta controllers, 1 ms is not enough for 16-port controllers, although it's good for 8-port controllers.

The correct internal mapping of stex controllers should be: id:0~15, lun:0~7 (st_shasta) id:0, lun:0~127 (st_yosemite) id:0~127, lun:0 (st_vsc and st_vsc1) This patch reports the internal mapping to scsi mid layer, eliminating the translation between scsi mid layer and firmware. To achieve this goal, we also need to: -- fail the REPORT_LUNS command for st_shasta because the firmware is known to not report all actual luns -- add an entry in scsi_devindo.c to force sequential lun scan (for st_shasta controllers) -- fail the REPORT_LUNS command for console device -- remove special handling of REPORT_LUNS command for st_yosemite, as there is no translation mapping now Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Currently ipr always returns success from eh_dev_reset when called for a SATA device. If ata_do_eh is unable to recover for some reason, this can result in commands that are still outstanding when ata_do_eh returns. Change ipr to verify no commands are outstanding before returning success. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

IO stall after deleting and path checker changes after reenabling zfcp device Setting one zfcp device offline using chccwdev in a multipath environment and waiting will lead to IO stall on all paths. After setting the zfcp device back online using chccwdev, the devices with io stall will have a different path checker. Devices corresponding to the deleted units are never freed. This has the effect that 'slave_destroy' is never called and zfcp still thinks that this unit is registered (ZFCP_STATUS_UNIT_REGISTERED is still set). Hence the erp routine is not called correctly and the unit is not enabled properly. Do not delete rport and the sdev. Just set the host to block on 'offline'. Setting host online again will then remove the blocked status and everything is fine again.

ide_use_dma() duplicates a lot of ide_max_dma_mode() functionality and as all users of ide_use_dma() were converted to use ide_tune_dma() now it is possible to add missing checks to ide_tune_dma() and remove ide_use_dma() completely, so do it.

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to program PIO5 by config_art_rwp_pio() could result in incorrect PIO timings being programmed and possibly the data corruption (for < ATA100 family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random content of test1 variable was used, for ATA133 - MWDMA0 timings were used) * BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5, also cleanup this function a bit while at it * add comment about PIO0 timings for < ATA100 family chipsets * remove open-coded best PIO mode selection from config_art_rwp_pio(), it contained numerous bugs: - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy before using them - it tried to found out maximum PIO mode basing on minimum IORDY cycle time (moreover wrong cycle times were used for PIO1/5) - it was overriding PIO blacklist and conservative PIO "downgrade" done by ide_get_best_pio_mode() * use sis5513_tune_drive() instead of config_art_rwp_pio() in sis5513_config_xfer_rate() so the correct PIO mode is also set on drive even if the device is not IORDY/DMA capable * config_art_rwp_pio() was always setting the best possible mode and not the wanted one - fix it and move ide_get_best_pio_mode() call to config_chipset_for_pio() * don't use ide_find_best_mode() in config_chipset_for_pio(), it was being overriden by config_art_rwp_pio() for the host timings anyway + we need to set the same PIO mode on the device and the host * pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call in sis5513_config_xfer_rate() so the best PIO mode is set on the drive and not PIO4 * rename sis5513_tune_drive() to sis5513_tuneproc() and config_chipset_for_pio() to sis5513_tune_driver() * bump driver version Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to program PIO5 by svwks_tune_chipset() could result in incorrect PIO timings being programmed and possibly the data corruption (it seems that the minimum possible values were used but I lack the datasheets to be sure) * select best PIO mode in svwks_tune_drive() and not in svwks_tune_chipset() when doing PIO autotuning (pio == 255) * don't try to tune PIO in config_chipset_for_dma() as ide_dma_enable() could return 1 if DMA was previously enabled (svwks_config_drive_xfer_rate() takes care of PIO tuning if no suitable DMA mode is found) * remove config_chipset_for_pio() and use svwks_tune_drive() instead, config_chipset_for_pio() contained numerous bugs when selecting PIO mode (luckily it was only used for devices limited to PIO by capabilities/BIOS): - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy before using them - it tried to found out maximum PIO mode basing on minimum IORDY cycle time (moreover wrong cycle times were used for PIO0/1/5) - it was overriding PIO blacklist and conservative PIO "downgrade" done by ide_get_best_pio_mode() - if the max drive PIO was PIO5 then XFER_PIO_0/XFER_PIO_SLOW was selected (XFER_PIO_SLOW is not supported by svwks_tune_chipset() so the result was the same as if using XFER_PIO_5 => wrong PIO timings were set) - it was overriding drive->current_speed * bump driver version Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

This patch is based on the documentation (I would like to thank Promise for it) and also partially on the older vendor driver. Rewrite mode programming code: * disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled even if both devices on the channel are not DMA capable and after reset * enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset() as they need to be setup correctly also for PIO only devices, plus IORDY wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for ATAPI devices * remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma() (driver sets ->autotune to 1 so PIO modes are always programmed => lower nibble of register A never equals 4 => "chipset_is_set" is always true) * enable PIO mode programming for all ATAPI devices (it was limited to ->media == ide_cdrom devices) * remove extra reads of registers A/B/C, don't read register D et all * do clearing / programming of registers A/B/C in one go (gets rid of extra PCI config space read/write cycle) * set initial values of drive_conf/AP/BP/CP variables to zero (paranoia for the case when PCI reads fail) * remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen (ide_rate_filter() takes care of it) * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones) * fix bitmasks for clearing bits of register B: - when programming DMA mode bit 0x10 of register B was cleared which resulted in overclocked PIO timing setting (iff PIO0 was used) - when programming PIO mode bits 0x18 weren't cleared so suboptimal timings were used for PIO1-4 if PIO0 was previously set (bit 0x10) and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08) * add FIXME comment about missing locking for 66MHz clock register Also while at it: * remove unused defines * do a few cosmetic / CodingStyle fixes * bump driver version v2: * in pdc202xx_tune_chipset() the old content of drive configuration registers is used only by the debugging code so cover "drive_conf" PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO (Noticed by Sergei Shtylyov) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

It was agreed that phy-connection-type was a better name for the interface-type property, so this patch renames it. Also, the max-speed property name was determined too generic, and is therefore eliminated in favour of phy-connection-type derivation logic. includes corrections to copyright text.
