Follow r261352 by updating all drivers which are children of simplebus to check the status property in their probe routines.

MFC Alexander Motin's direct dispatch, multi-queue, and finer-grained

2014-01-07T01:51:48Z

locking support for CAM r256826: Fix several target mode SIMs to not blindly clear ccb_h.flags field of ATIO CCBs. Not all CCB flags there belong to them. r256836: Remove hard limit on number of BIOs handled with one ATA TRIM request. r256843: Merge CAM locking changes from the projects/camlock branch to radically reduce lock congestion and improve SMP scalability of the SCSI/ATA stack, preparing the ground for the coming next GEOM direct dispatch support. r256888: Unconditionally acquire periph reference on CCB allocation failure. r256895: Fix memory and references leak due to unfreed path. r256960: Move CAM_UNQUEUED_INDEX setting to the last moment and under the periph lock. This fixes race condition with cam_periph_ccbwait(), causing use-after-free. r256975: Minor (mostly cosmetical) addition to r256960. r257054: Some microoptimizations for da and ada drivers: - Replace ordered_tag_count counter with single flag; - From da remove outstanding_cmds counter, duplicating pending_ccbs list; - From da_softc remove unused links field. r257482: Fix lock recursion, triggered by `smartctl -a /dev/adaX`. r257501: Make getenv_*() functions and respectively TUNABLE_*_FETCH() macros not allocate memory and so not require sleepable environment. getenv() has already used on-stack temporary storage, so just use it more rationally. getenv_string() receives buffer as argument, so don't need another one. r257914: Some CAM locks polishing: - Fix LOR and possible lock recursion when handling high-power commands. Introduce new lock to protect left power quota and list of frozen devices. - Correct locking around xpt periph creation. - Remove seems never used XPT_FLAG_OPEN xpt periph flag. Again, Netflix assisted with testing the merge, but all of the credit goes to Alexander and iX Systems. Submitted by: mav Sponsored by: iX Systems

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI

command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot. Submitted by: jhb Reviewed by: jfv, marius, achadd, achim MFC after: 1 day
