* Partially revert r236666:Alexander Motin2012-06-101-1/+1
| | | | | | | | | | | | | | Return PROTO_ATA protocol in response to XPT_PATH_INQ. smartmontools uses it to identify ATA devices and I don't know any other place now where it is important. It could probably use XPT_GDEV_TYPE instead for more accurate protocol information, but let it live for now. Reported by: matthew MFC after: 3 days Notes: svn path=/head/; revision=236847
* ATA/SATA controllers have no idea about protocol of the connected deviceAlexander Motin2012-06-061-2/+2
| | | | | | | | | | until transport will do some probe actions (at least soft reset). Make ATA/SATA SIMs to not report bogus and confusing PROTO_ATA protocol. Make ATA/SATA transport to fill that gap by reporting protocol to SIM with XPT_SET_TRAN_SETTINGS and patching XPT_GET_TRAN_SETTINGS results if needed. Notes: svn path=/head/; revision=236666
* Add two functions xpt_batch_start() and xpt_batch_done() to the CAM SIM KPIAlexander Motin2012-05-121-0/+2
| | | | | | | | | | | | to allow drivers to handle request completion directly without passing them to the CAM SWI thread removing extra context switch. Modify all ATA/SATA drivers to use them. Reviewed by: gibbs, ken MFC after: 2 weeks Notes: svn path=/head/; revision=235333

* Move the device_delete_all_children() function from usb_util.cHans Petter Selasky2011-11-191-7/+2
| | | | | | | | | | | to kern/subr_bus.c. Simplify this function so that it no longer depends on malloc() to execute. Identify a few other places where it makes sense to use device_delete_all_children(). MFC after: 1 week Notes: svn path=/head/; revision=227701

* According to SATA specification, when Serial ATA Enclosure Management BridgeAlexander Motin2011-05-251-7/+18
| | | | | | | | | | | | | | | | | | | | | | | (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.

* Improve SATA Asynchronous Notification feature support in CAM:Alexander Motin2011-04-131-0/+5
| | | | | | | | | | | | | | | | - 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

* MFp4: Large set of CAM inprovements.Alexander Motin2010-01-281-9/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* Explicitly acknowledge MSI completion, as required by SiI3124 datasheet.Alexander Motin2009-12-072-3/+14

* MFp4:Alexander Motin2009-11-242-23/+71
| | | | | | | | | | | | | | | - Extend XPT-SIM transfer settings control API. Now it allows to report to SATA SIM number of tags supported by each device, implement ATA mode and SATA revision negotiation for both SATA and PATA SIMs. - Make ahci(4) and siis(4) to use submitted maximum tag number, when scheduling requests. It allows to support NCQ on devices with lower tags count then controller supports. - Make PMP driver to report attached devices connection speeds. - Implement ATA mode negotiation between user settings, device and controller capabilities. Notes: svn path=/head/; revision=199747

| | | | | | | | | | | | | - Move tagged queueing control from ADA to ATA XPT. It allows to control device command queue length correctly. First step to support < 32 tags. - Limit queue for non-tagged devices by 2 slots for ahci(4) and siis(4). - Implement quirk matching for ATA devices. - Move xpt_schedule_dev_sendq() from header to source file. - Move delayed queue shrinking to the more expected place - element freeing. - Remove some SCSIsms in ATA.

| | | | | | | | | | | | - Rework timeout handling, to make it more graceful for devices sharing controller port (with PMP). Wait for other commands completion/timeout before initiating recovery. - Handle timeouts and fatal errors with port hard-reset. The rest of recovery will be done by XPT on receiving async event. More gracefull per-device soft-reset recovery can be implemented later. Notes: svn path=/head/; revision=198852

* Add `siis` CAM driver for SiliconImage SiI3124/3132/3531 SATA2 controllers.Alexander Motin2009-07-212-0/+2017
Driver supports Serial ATA and ATAPI devices, Port Multipliers (including FIS-based switching), hardware command queues (31 command per port) and Native Command Queuing. This is probably the second on popularity, after AHCI, type of SATA2 controllers, that benefits from using CAM, because of hardware command queuing support.
