* 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
* Adjust mvs(4) to handle interrupt cause reg depending on the actual number ofRafal Jaworowski2012-02-012-10/+16
| | | | | | | | | | | | | | | | | | | channels available - current code treats bits 4:7 in 'SATAHC interrupt mask' and 'SATAHC interrupt cause' as flags for SATA channels 2 and 3 - for embedded SATA controllers (SoC) these bits have been marked as reserved in datasheets so far, but for some new and upcoming chips they are used for purposes other than SATA Submitted by: Lukasz Plachno Reviewed by: mav Obtained from: Semihalf MFC after: 2 weeks Notes: svn path=/head/; revision=230865
* Rename device_delete_all_children() into device_delete_children().Hans Petter Selasky2011-11-222-2/+2

* Move the device_delete_all_children() function from usb_util.cHans Petter Selasky2011-11-192-14/+4
| | | | | | | | | | | 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 Motin2011-05-251-10/+34
| | | | | | | | | | | | | | | | | | | | | | | (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.

* Refactor hard-reset implementation in mvs(4).Alexander Motin2011-04-142-17/+86
| | | | | | | | | | | | Instead of spinning in a tight loop for up to 15 seconds, polling for device readiness while it spins up, return reset completion just after PHY reports "connect well" or 100ms connection timeout. If device was found, use callout for checking device readiness with 100ms period up to full 31 second timeout. This fixes system freeze for 5-10 seconds on drives hot plug-in.

* Improve SATA Asynchronous Notification feature support in CAM:Alexander Motin2011-04-131-0/+15
| | | | | | | | | | | | | | | | - 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
