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. 2010-02-14T12:04:25Z Alexander Motin mav@FreeBSD.org 2010-02-14T12:04:25Z urn:sha1:6228bcd1ee400d43a1f470d91bb8f9f13ec5d410 When hacking INQUIRY result, make sure that it is right INQUIRY and there is enough of result to hack. 2010-02-14T12:03:04Z Alexander Motin mav@FreeBSD.org 2010-02-14T12:03:04Z urn:sha1:9a1be4e8d1e6dd22851ec79b8255f0fa0feec372 Return CAM_RELEASE_SIMQ flag only when it is needed, when SIM really was frozen before and should be released. 2009-12-31T12:58:08Z Gavin Atkinson gavin@FreeBSD.org 2009-12-31T12:58:08Z urn:sha1:d36f5405ca1a94cb870499e42ee91f2f1924f758 Don't panic due to unlocking an unowned mutex if we fail during attach.
