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.

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. 2013-06-27T09:30:09Z Marius Strobl marius@FreeBSD.org 2013-06-27T09:30:09Z urn:sha1:da24747821b315dec48cdbd4462c21ca763a1179 Flag mpt(4) as supporting unmapped I/O; all necessary conversion actually already has been done as part of r246713 (MFCed to stable/9 in r251874) except for a comment update. 2013-06-18T04:03:12Z Xin LI delphij@FreeBSD.org 2013-06-18T04:03:12Z urn:sha1:7fd5735f9b6980887b2f8eec32fc6fc675fadab6 Explicitly use a pair of parentheses to ensure correct evaluation ordering for bitwise operation.

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.

That should allow CAM to do final cache flush at the SHUTDOWN_PRI_DEFAULT without using polling magic. 2013-01-27T17:15:56Z Marius Strobl marius@FreeBSD.org 2013-01-27T17:15:56Z urn:sha1:880695fcd3b902a998826863b1c1f8f32761b3ad Remove support for using Giant for locking within mpt(4).
