MFC r246713: 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. MFC r249538: Some compilers issue a warning when wider integer is casted to narrow pointer. Supposedly shut down the warning by casting through uintptr_t. MFC r251479: Simplify the checking of flags for cam_periph_mapmem(). This gets rid of a lot of code redundancy and grossness at very minor expense. MFC r251837: MFC r251842: Add infrastructure for doing compatibility shims, as has been sorely needed for the last 10 years. Far too much of the internal API is exposed, and every small adjustment causes applications to stop working. To kick this off, bump the API version to 0x17 as should have been done with r246713, but add shims to compensate. Thanks to the shims, there should be no visible change in application behavior.

All other ATA PIO commands transfer one sector or 512 bytes at one time. Hardcode these exceptions in mvs(4). This fixes timeout of READ LOG EXT command used by `smartctl -x /dev/adaX`. Also it fixes timeout of DOWNLOAD_MICROCODE on `camcontrol fwdownload`. 2013-04-05T08:22:11Z Alexander Motin mav@FreeBSD.org 2013-04-05T08:22:11Z urn:sha1:1139d398ea93668ee65ae02b8ceab630ca9e5487 Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs. This means that their use is restricted to a single C file. 2012-06-21T10:28:59Z Alexander Motin mav@FreeBSD.org 2012-06-21T10:28:59Z urn:sha1:cabec68cbb673e1db6def64ed6fdd9d5e93b27d6 - Limit r214102 workaround to only x86. On arm it causes more problems 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. 2012-06-12T08:08:33Z Alexander Motin mav@FreeBSD.org 2012-06-12T08:08:33Z urn:sha1:4156f7507944b1d27df6ddb8457c027e9113788a Partially revert r236666: 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. 2012-06-09T07:53:57Z Alexander Motin mav@FreeBSD.org 2012-06-09T07:53:57Z urn:sha1:3a009c7d1087f51ab0dbf01562ea4151d6771385 ATA/SATA controllers have no idea about protocol of the connected device 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. 2012-06-04T07:03:56Z Alexander Motin mav@FreeBSD.org 2012-06-04T07:03:56Z urn:sha1:041e8cc5d05b87955a52af63b3c5d41ba66dbd13 Add two functions xpt_batch_start() and xpt_batch_done() to the CAM SIM KPI 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. 2012-03-04T17:53:40Z Rafal Jaworowski raj@FreeBSD.org 2012-03-04T17:53:40Z urn:sha1:6b7e5f9eaa988f027c13a877bd542b285bbad972 Adjust mvs(4) to handle interrupt cause reg depending on the actual number of 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 2011-12-31T15:31:34Z Hans Petter Selasky hselasky@FreeBSD.org 2011-12-31T15:31:34Z urn:sha1:736975dfb8ec99c3135aa6fe28a315dcd6fbad67 Move the device_delete_all_children() function from usb_util.c to kern/subr_bus.c. Simplify this function so that it no longer depends on malloc() to execute. Rename device_delete_all_children() into device_delete_children(). Identify a few other places where it makes sense to use device_delete_children().
