* Reform the busdma API so that new types may be added without modifyingKonstantin Belousov2013-02-121-13/+2
| | | | | | | | | | | | | | | | | | | | | | | | every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.

* In some cases, at least on Marvell 88SE912x controllers, Current CommandAlexander Motin2011-07-292-6/+15
| | | | | | | | | | | | | | | Slot field of the PxCMD register may point to an empty command slot. That breaks command timeout detection logic, making impossible to find what command actually caused timeout, and leading to infinite wait. Workaround that by checking whether pointed command slot is really used and can timeout in its time. And if not, fallback to the dumb algorithm used with FBS -- let all commands to time out and then fail all of them. Approved by: re (kib) MFC after: 1 week Notes: svn path=/head/; revision=224498

* Marvell 88SE91xx controllers are known to report soft-reset completionAlexander Motin2011-05-261-28/+49
| | | | | | | | | | | | | | | | | without waiting for device readiness (or at least not updating FIS receive area in time). To workaround that, special quirk was added earlier to wait for the FIS receive area update. But it was found that under same PCI ID 0x91231b4b and revision 0x11 there are two completely different chip versions (firmware?): HBA and RAID. The problem is that RAID version in some cases, such as hot-plug, does not update FIS receive area at all! To workaround that, differentiate the chip versions by their capabilities, and, if RAID version found, skip FIS receive area update waiting and read device signature from the PxSIG register instead. This method doesn't work for HBA version when PMP attached, so keep using previous workaround there. Notes: svn path=/head/; revision=222304
* According to SATA specification, when Serial ATA Enclosure Management BridgeAlexander Motin2011-05-251-12/+13
| | | | | | | | | | | | | | | | | | | | | | | (SEMB) is unable to communicate to Storage Enclosure Processor (SEP), in response to hard and soft resets it should among other things return value 0x7F in Status register. The weird side is that it means DRQ bit set, which tells that reset request is not completed. It would be fine if SEMB was the only device on port. But if SEMB connected to PMP or built into it, it may block access to other devices sharing same SATA port. Make some tunings/fixes to soft-reset handling to workaround the issue: - ahci(4): request CLO on the port after soft reset to ignore DRQ bit; - siis(4): gracefully reinitialize port after soft reset timeout (hardware doesn't detect reset request completion in this case); - mvs(4): if PMP is used, send dummy soft-reset to the PMP port to make it clear DRQ bit for us. For now this makes quirks in ata_pmp.c, hiding SEMB ports of SiI3726/SiI4726 PMPs, less important. Further, if hardware permit, I hope to implement real SEMB support.

* Add support for "LED" enclosure management messages, defined by the AHCI.Alexander Motin2011-05-172-0/+83
| | | | | | | | | | | | When supported by hardware, this allows to control per-port activity, locate and fault LEDs via the led(4) API for localization and status reporting purposes. Supporting AHCI controllers may transmit that information to the backplane controllers via SGPIO interface. Backplane controllers interpret received statuses in some way (IBPI standard) to report them using present indicators. Notes: svn path=/head/; revision=222039

* Some changes around hot-plug and interface power-management:Alexander Motin2011-04-152-15/+65
| | | | | | | | | | | | | | | - use ATA_SE_EXCHANGED (SError.DIAG.X) bit to detect hot-plug events when power-management enabled and ATA_SE_PHY_CHANGED (SError.DIAG.N) can't be trusted; - on controllers supporting staggered spin-up (SS) put unused channels into Listen state instead of Off. It should still save some power, but allow plug-in events to be detected; - on controllers supporting cold presence detection (CPD), when power management enabled, use CPD events to detect hot-plug in addition to PHY events.

* Improve SATA Asynchronous Notification feature support in CAM:Alexander Motin2011-04-131-1/+3
| | | | | | | | | | | | | | | | - make SATA SIMs announce capabilities to handle SDB with Notification bit; - make PMP driver honor this SIMs capability; - make SATA XPT to negotiate and enable this feature for ATAPI devices. This feature allows supporting SATA ATAPI devices to inform system about some events happened, that may require attention. In my case this allows LG GH22LS50 SATA DVR-RW drive to report tray open/close events. Events reported to CAM in form of AC_SCSI_AEN async. Further they could be used as a hints for checking device status and reporting media change to upper layers, for example, via spoiling mechanism of GEOM. Notes: svn path=/head/; revision=220602
