* MFC r295276: Add defines for WRITE_UNCORRECTABLE ATA command, and improverpokala2016-03-061-8/+92
| | | | | | | | | | | command logging Add #defines for ATA_WRITE_UNCORRECTABLE48 and its features. Update the decoding in ATACAM to recognize the new values. Also improve command decoding for a few other commands (SMART, NOP, SET_FEATURES). Bring the decoding in ata(4) up to parity with ATACAM. Sponsored by: Panasas, Inc.

* MFC r286814, r286816: Remove UMA allocation of ATA requests.mav2015-08-292-36/+3
| | | | | | After CAM replaced old ATA stack, this driver processes no more then one request at a time per channel. Using UMA after that is overkill, so replace it with simple preallocation of one request per channel.
* MFC r286448: Disable 32-bit PIO for 6Gbit/s Intel SATA controllers.mav2015-08-222-21/+24
| | | | | | | | | | | For some reason 32-bit PIO writes are not working on 6Gbit/s Intel SATA ports, while 16/32-bit PIO reads and 16-bit PIO writes are working fine. 3Gbit/s ports on the same controllers have no this problem. Workaround this by disabling 32-bit PIO for all Intel controllers that may have 6Gbit/s ports. It halves PIO performance from 6MB/s to 3MB/s, but who bother about speed of such rare and slow mode, which is also highly discouraged by SATA specifications?
* MFC r280451:mav2015-08-2212-2485/+16
| | | | | | | Remove from legacy ata(4) driver support for hardware, supported by newer and more functional drivers ahci(4), siis(4) and mvs(4). This removes about 3400 lines of code, unused since FreeBSD 9.0 release.
* MFC r280393: Reduce priority of ATA/SATA drivers.mav2015-04-0624-24/+24

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 PCIscottl2013-08-121-4/+1
| | | | | | | | | | | | | | | | | 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

The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.

Most of these are of the form: static const struct bzzt_type { [...list of members...] } const bzzt_devs[] = { [...list of initializers...] }; The second const is unnecessary, as arrays cannot be modified anyway, and if the elements are const, the whole thing is const automatically (e.g. it is placed in .rodata).
