* [PATCH] libata: Incorrect timing computation for PIO5/6Alan2006-12-071-1/+1

* [PATCH] sata_promise: new EH conversion, take 2Mikael Pettersson2006-12-071-12/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts sata_promise to use new-style libata error handling on Promise SATA chips, for both SATA and PATA ports. * ATA_FLAG_SRST is no longer set * ->phy_reset is no longer set as it is unused when ->error_handler is present, and pdc_sata_phy_reset() has been removed * pdc_freeze() masks interrupts and halts DMA via PDC_CTLSTAT * pdc_thaw() clears interrupt status in PDC_INT_SEQMASK and then unmasks interrupts in PDC_CTLSTAT * pdc_error_handler() reinitialises the port if it isn't frozen, and then invokes ata_do_eh() with standard {s,}ata reset methods * pdc_post_internal_cmd() resets the port in case of errors * the PATA-only 20619 chip continues to use old-style EH: not by necessity but simply because I don't have documentation for it or any way to test it Since the previous version pdc_error_handler() has been rewritten and it now mostly matches ahci and sata_sil24. In case anyone wonders: the call to pdc_reset_port() isn't a heavy-duty reset, it's a light-weight reset to quickly put a port into a sane state. The discussion about the PCI flushes in pdc_freeze() and pdc_thaw() seemed to end with a consensus that the flushes are OK and not obviously redundant, so I decided to keep them for now. This patch was prepared against 2.6.19-git7, but it also applies to 2.6.19 + libata #upstream, with or without the revised sata_promise cleanup patch I recently submitted. This patch does conflict with the #promise-sata-pata patch: this patch removes pdc_sata_phy_reset() while #promise-sata-pata modifies it. The correct patch resolution is to remove the function. Tested on 2037x and 2057x chips, with PATA patches on top and disks on both SATA and PATA ports. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* [PATCH] sata_promise: cleanups, take 2Mikael Pettersson2006-12-071-31/+9
| | | | | | | | | | | | | | | | | | | | | | | This patch performs two simple cleanups of sata_promise. * Remove board_20771 and map device id 0x3577 to board_2057x. After the recent corrections for SATAII chips, board_20771 and board_2057x were equivalent in the driver. * Remove hp->hotplug_offset and use hp->flags & PDC_FLAG_GEN_II to compute hotplug_offset in pdc_host_init(). hp->hotplug_offset was used to distinguish 1st and 2nd generation chips in one particular case, but now we have that information in a more general form in hp->flags, so hp->hotplug_offset is redundant. Changes since previous submission: rebased on libata-dev #upstream, cleaned up hotplug_offset computation based on Tejun's comments, expanded hotplug_offset removal rationale. This patch does not depend on the pending new EH conversion patch. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * [PATCH] sata_promise: PHYMODE4 fixupMikael Pettersson2006-12-031-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds code to fix up the PHYMODE4 "align timing" register value on second-generation Promise SATA chips. Failure to correct this value on non-x86 machines makes drive detection prone to failure due to timeouts. (I've observed about 50% detection failure rates on SPARC64.) The HW boots with a bad value in this register, but on x86 machines the Promise BIOS corrects it to the value recommended by the manual, so most people have been unaffected by this issue. After developing the patch I checked Promise's SATAII driver, and discovered that it also corrects PHYMODE4 just like this patch does. This patch depends on the sata_promise SATAII updates patch I sent recently. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: always use polling IDENTIFYTejun Heo2006-12-034-14/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata switched to IRQ-driven IDENTIFY when IRQ-driven PIO was introduced. This has caused a lot of problems including device misdetection and phantom device. ATA_FLAG_DETECT_POLLING was added recently to selectively use polling IDENTIFY on problemetic drivers but many controllers and devices are affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING for each such case is diffcult and not very rewarding. This patch makes libata always use polling IDENTIFY. This is consistent with libata's original behavior and drivers/ide's behavior.

| * [PATCH] ahci: do not powerdown during initializationTejun Heo2006-12-031-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ahci_init_controller() calls ahci_deinit_port() to make sure the controller is stopped before initializing the controller. In turn, ahci_deinit_port() invokes ahci_power_down() to power down the port. If the controller supports slumber mode, the link is put into it. Unfortunately, some devices don't implement link powersaving mode properly and show erratic behavior after link is put into slumber mode. For example, HL-DT-ST DVD-RAM GSA-H30N completely locks up on slumber transition and can only be recovered with the *REAL* hard reset - power removal and reapply. Note that this makes the first probing reset different from all others. If the above dvd-ram is hotplugged after ahci is initialized, no problem occurs because ahci is already fully initialized with phy powered up. So, this might also be the reason for other weird AHCI initial probing abnormalities. This patch moves power up/down out of port init/deinit and call them only when needed. Power down is now called only when suspending. As system suspend usually involves powering down 12v for storage devices, this shouldn't cause problem even if the attached device doesn't support slumber mode. However, in partial power management and suspend failure cases, devices might lock up after suspend attempt. I thought about removing transition to slumber mode altogether but ahci spec mandates it before HBA D3 state transition. Blacklisting such devices might be the solution.

| * [PATCH] libata: make sure IRQ is cleared after ata_bmdma_freeze()Tejun Heo2006-12-032-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that BMDMA status is recorded in irq handler. ata_bmdma_freeze() is free to manipulate host status. Under certain circumstances, some controllers (ICH7 in enhanced mode w/ IRQ shared) raise IRQ when CTL register is written to and ATA_NIEN doesn't mask it. This patch makes ata_bmdma_freeze() clear all pending IRQs after freezing a port. This change makes explicit clearing in ata_device_add() unnecessary and thus kills it. The removed code was SFF-specific and was in the wrong place. Note that ->freeze() handler is always called under ap->lock held and irq disabled. Even if CTL manipulation causes stuck IRQ, it's cleared immediately. This should be safe (enough) even in SMP environment. More correct solution is to mask the IRQ from IRQ controller but that would be an overkill. Signed-off-by: Tejun Heo <htejun@gmail.com>

| * [PATCH] libata: set IRQF_SHARED for legacy PCI IDE IRQsTejun Heo2006-12-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are machines out there which share legacy PCI IDE IRQs w/ other devices. libata SFF interrupt/HSM code is ready for shared IRQ and has been setting IRQF_SHARED for devices in native PCI mode. Device in legacy mode is still a PCI device and thus supposedly uses active-low level triggered IRQ. Machines with such setup should be quite rare and w/o this flag libata is likely to fail loading and render the system unuseable. Also, IDE driver has been setting IRQF_SHARED for devices in legacy mode for a looooong time. Signed-off-by: Tejun Heo <htejun@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv with ATAPI devices on controllers running in ADMA mode. Some of the logic in the nv_adma_bmdma_* functions was inverted causing a bunch of warnings and caused those functions not to work properly. Also, when an ATAPI device is connected, we need to use the legacy DMA engine. The code now disables the PCI configuration register bits for ADMA so that this works, and ensures that no ATAPI DMA commands go through until this is done.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
