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.

There are some systems reported, where PCI BAR(5), used for SATA registers access, is present, but not functional. Attempt to use it brakes devices detection logic. Try to detect those cases on attach by setting and testing some bits in SControl register. If bits are unsettable, fallback to legacy ATA without hot-plug detection, speed control/reporting, etc. 2013-07-08T15:54:38Z Alexander Motin mav@FreeBSD.org 2013-07-08T15:54:38Z urn:sha1:3e4e5885166ea909e8b4fb152427c50e5d311a22 Stop abusing xpt_periph in random plases that really have no periph related to CCB, for example, bus scanning. NULL value is fine in such cases and it is correctly logged in debug messages as "noperiph". If at some point we need some real XPT periphs (alike to pmpX now), quite likely they will be per-bus, and not a single global instance as xpt_periph now. 2013-06-25T07:05:08Z Alexander Motin mav@FreeBSD.org 2013-06-25T07:05:08Z urn:sha1:2685b09442c5609126ae71548f8c2511574d988d Pass proper memory type to free() in ata_ali_chipinit(). 2013-06-18T14:35:09Z Marius Strobl marius@FreeBSD.org 2013-06-18T14:35:09Z urn:sha1:661eff4d1d1ba862f083ba5e2e2be9fc09904c53 Fix command timeout caused by data underrun during fetching ATAPI sense data, introduced by r246713 (MFC'ed to stable/9 in r251874). There are two places where ata_request is filled in ATA_CAM: ata_cam_begin_transaction() and ata_cam_request_sense(). In the first case DMA should be done for addresses from the CCB. In second case, DMA should be done to the different address, the address of the sense buffer inside the CCB structure itself. 2013-06-18T00:36:53Z Scott Long scottl@FreeBSD.org 2013-06-18T00:36:53Z urn:sha1:039e422c063977ba9073fd2c93883dd8a5a36d48 have been in production at Netflix for several months with significant success. 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.
