2014-05-15T16:11:06Z

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

r257282, r257332 Wait for DesignWare UART transfers completion before accessing line control Enable UART busy detection handling for Armada XP - based board Enable SATA interface on Armada XP Run mvs SATA driver on Armada XP instead of old mv_sata Retire arm_remap_nocache() and the data and constants associated with it. Remove hard-coded mappings related to Armada XP support Fix-up DTB for Armada XP registers' base according to the actual settings Change Armada XP kernel load address to the u-boot's end address Remove not working and deprecated PJ4Bv6 support Switch off explicit broadcasting of the TLB flush operations for PJ4B CPU Add missing ARMv6 CPU functions to ARM Makefile

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this shifts into the sign bit. Instead use (1U << 31) which gets the expected result. Similar to the (1 << 31) case it is not defined to do (2 << 30). This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases. A similar change was made in OpenBSD.

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

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

Replicate r242422 from ata(4) to mvs(4):

2013-06-12T18:08:11Z

Only four specific ATA PIO commands transfer several sectors per DRQ block (interrupt). All other ATA PIO commands transfer one sector or 512 bytes at one time. Hardcode these exceptions in mvs(4) with ATA_CAM option. This fixes timeout of READ LOG EXT command used by `smartctl -x /dev/adaX`. Also it fixes timeout of DOWNLOAD_MICROCODE on `camcontrol fwdownload`.

Reform the busdma API so that new types may be added without modifying

every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. 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.

then solves because of cache coherency issues. This fixes periodic error messages on console and command timeouts. - Patch SATA PHY configuration for 65nm SoCs to improve SNR same as Linux does. MFC after: 2 weeks

Partially revert r236666:

2012-06-10T11:17:14Z

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
