* Use new helper functions to set PCIe max read request size.Alexander Motin2010-02-051-12/+2
| | | | Notes: svn path=/head/; revision=203529
* - Give ATA/SATA SIMs info about ATAPI packet size, supported by device.Alexander Motin2010-02-022-0/+5
| | | | | | | | - Make ATA XPT to reject longer SCSI CDBs then supported by device, or any SCSI CDBs, if device doesn't support ATAPI. Notes: svn path=/head/; revision=203376
* Reset port on disconnect event, to abort any running requests.Alexander Motin2010-01-291-8/+6

* 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.

* Usually these controllers are able to automatically decode command code toAlexander Motin2009-12-292-5/+27

* Increase Max Read Request Size for PCIe chips from 512 to 1024 bytes.Alexander Motin2009-12-091-0/+13
| | | | | | | It gives those beasts additional 10% of write bandwidth. Notes: svn path=/head/; revision=200291
* Explicitly acknowledge MSI completion, as required by SiI3124 datasheet.Alexander Motin2009-12-072-3/+14
| | | | | | | | | It makes MSI working there. Later (and cheaper) PCIe chips (3132/3531) still randomly crashing system in few seconds of high MSI rates, generating something inaporopriate, like NMI or "Fatal trap 30". Notes: svn path=/head/; revision=200223
* SiI3124 has no SNotification register. Handle Asynchronous NotificationsAlexander Motin2009-12-072-12/+27

| | | | | | | Improve ATA mode/SATA revision control. Notes: svn path=/head/; revision=199821
* 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
* Do not require payload data to be aligned. It is not mentioned in datasheetAlexander Motin2009-11-161-1/+1
| | | | | | | and works fine in practice. Notes: svn path=/head/; revision=199333
* MFp4:Alexander Motin2009-11-111-1/+1
| | | | | | | | | | | | | - 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.

* MFp4:Alexander Motin2009-11-032-49/+104
| | | | | | | | | | | | - 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
* Reimplement device reset sequence in more controller-specific way.Alexander Motin2009-10-231-38/+34

* MFp4:Alexander Motin2009-10-211-1/+1
| | | | | | | | Report real max_target = 15. SIM doesn't need to know that target 15 is PMP. It is XPT business. Notes: svn path=/head/; revision=198322
* MFp4:Alexander Motin2009-10-211-7/+26
| | | | | | | Freeze device queue on error to permit periph driver to do proper recovery. Notes: svn path=/head/; revision=198321

* 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.
