* MFC r215468:Alexander Motin2010-11-232-0/+20
| | | | | | | | | Make ATA_CAM wrapper to report SATA power management capabilities to CAM to make it configure device to initiate transitions if controller configured to accept them. This makes hint.ata.X.pm_level=1 mode working. Notes: svn path=/stable/8/; revision=215777
* MFC r215453:Alexander Motin2010-11-231-1/+5
| | | | | | | | Even if we are skipping SATA hard reset - set power management bits in SControl register. This should make things more consistent. Notes: svn path=/stable/8/; revision=215776

* MFC r209683 by imp:Alexander Motin2010-11-191-3/+8
| | | | | | | | | | | Add a safety-belt. If the identified disk has 0 blocks, don't attach it. This can happen in some cases when plugging in SD/SmartCard PC Cards with empty slots. It is better to detect this bogosity, and refuse to attach rather than panic with a division by zero (in one of many places) down stream. Notes: svn path=/stable/8/; revision=215511

* MFC r214016:Alexander Motin2010-11-0211-155/+508
| | | | | | | | | | | | | | | | Set of legacy mode SATA enchancements: - Implement proper combined mode decoding for Intel controllers to properly identify SATA and PATA channels and associate ATA channels with SATA ports. This fixes wrong reporting and in some cases hard resets to wrong SATA ports. - Improve SATA registers support to handle hot-plug events and potentially interface errors. For ICH5/6300ESB chipsets these registers accessible via PCI config space. For later ones they may be accessible via PCI BAR(5). - For controllers not generating interrupts on hot-plug events, implement periodic status polling. Use it to detect hot-plug on Intel and VIA controllers. Same probably could also be used for Serverworks and SIS. Notes: svn path=/stable/8/; revision=214671
* MFC r213301:Alexander Motin2010-11-021-2/+1
| | | | | | | | | Revert r132291. Restore setting PIO/WDMA timings for VIA UDMA133 controllers. Linux disables only AST register writing there, but no all timings. Notes: svn path=/stable/8/; revision=214669

* MFC r212359:Nathan Whitehorn2010-09-303-19/+34
| | | | | | | | | | | | Fix a problem where device detection would work unreliably on Serverworks K2 SATA controllers. The chip's status register must be read first, and as a long, for other registers to be correctly updated after a command, and this includes the command sequence in device detection as well as the previously handled case after interrupts. While here, clean up some previous hacks related to this controller. Notes: svn path=/stable/8/; revision=213291
* MFC r212146:Alexander Motin2010-09-161-0/+8
| | | | | | | | | | Add workaround for SiI3114 and SiI3512 chips bug, which caused sending R_ERR in response to DMA activate FIS under certain circumstances. This is recommended fix from chip datasheet. If triggered, this bug most likely caused write command timeout. Notes: svn path=/stable/8/; revision=212720
* MFC r212145:Alexander Motin2010-09-163-17/+15
| | | | | | | | | | | SATA1.x SiliconImage controllers on power-on reset TFD Status register into value 0xff. On hot-plug this value confuses ata_generic_reset() device presence detection logic. As soon as we already know drive presence from SATA hard reset, hint ata_generic_reset() to wait for device signature until success or full timeout. Notes: svn path=/stable/8/; revision=212719
* MFC r212081:Alexander Motin2010-09-161-1/+1
| | | | | | | | Increase device reset timeout from 10 to 15 seconds, same as in ahci(4). Some devices found need about 10-12 seconds to spinup. Notes: svn path=/stable/8/; revision=212718

| | | | | | | | | | | | | | | | | Program the K2 SATA controller's interrupt to be level-triggered low, and respect the edge/level settings in the device tree. OpenPIC on powerpc sets interrupts to be level high by default. On Apple interrupt controllers, all level interrupts are low regardless of programming except interrupt 0, used by K2 SATA on some Apple systems, with the result that the K2 SATA IRQ is misconfigured. Pending review of changes to this default, work around this by changing the programming of the K2 SATA interrupt to level low. Approved by: re (kib) Notes: svn path=/stable/8/; revision=209044
* MFC r208870:Nathan Whitehorn2010-06-113-1/+21
| | | | | | | | | | | | | | | | | Some revisions of the Serverworks K2 SATA controller have a data corruption bug where if an ATA command is issued before DMA is started, data will become available to the controller before it knows what to do with it. This results in either data corruption or a controller crash. This patch remedies the problem by adopting the workaround employed by Linux and Darwin: starting the DMA engine prior to sending the ATA command.

While at it, rename *ad_firmware_geom_adjust() to *ata_disk_firmware_geom_adjust() etc now that these are no longer limited to ad(4).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Large set of CAM improvements: - Unify bus reset/probe sequence. Whenever bus attached at boot or later, CAM will automatically reset and scan it. It allows to remove duplicate code from many drivers. - Any bus, attached before CAM completed it's boot-time initialization, will equally join to the process, delaying boot if needed. - New kern.cam.boot_delay loader tunable should help controllers that are still unable to register their buses in time (such as slow USB/ PCCard/ CardBus devices), by adding one more event to wait on boot. - To allow synchronization between different CAM levels, concept of requests priorities was extended. Priorities now split between several "run levels". Device can be freezed at specified level, allowing higher priority requests to pass. For example, no payload requests allowed, until PMP driver enable port. ATA XPT negotiate transfer parameters, periph driver configure caching and so on. - Frozen requests are no more counted by request allocation scheduler. It fixes deadlocks, when frozen low priority payload requests occupying slots, required by higher levels to manage theit execution. - Two last changes were holding proper ATA reinitialization and error recovery implementation. Now it is done: SATA controllers and Port Multipliers now implement automatic hot-plug and should correctly recover from timeouts and bus resets. - Improve SCSI error recovery for devices on buses without automatic sense reporting, such as ATAPI or USB. For example, it allows CAM to wait, while CD drive loads disk, instead of immediately return error status. - Decapitalize diagnostic messages and make them more readable and sensible. - Teach PMP driver to limit maximum speed on fan-out ports. - Make boot wait for PMP scan completes, and make rescan more reliable. - Fix pass driver, to return CCB to user level in case of error. - Increase number of retries in cd driver, as device may return several UAs.
