Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI 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, adrian, achim Approved by: re

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.

Big MFC of the physbio changes necessary for unmapped I/O. These changes

2013-06-18T00:36:53Z

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.

Use CAM_DEV_NOT_THERE instead of CAM_SEL_TIMEOUT to report nonexistent LUNs for the virtual processor device. This removes lots of CAM warnings, and follows similar recent changes to tws(4) and twa(4) drivers. Also fix case where CAM_REQ_CMP was getting OR'd with CAM_DEV_NOT_THERE in the nonexistent LUN case, resulting in different CAM status (CAM_UA_TERMIO) getting reported to CAM. This issue existing previously, but was more subtle because it changed CAM_SEL_TIMEOUT to CAM_CMD_TIMEOUT. Sponsored by: Intel Reported and tested by: Willem Jan Withagen

- Just use cam_calc_geometry(9) on newer version of FreeBSD rather than duplicating it. - In hptmv(4) and hptrr(4) use __FBSDID and DEVMETHOD_END.
