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.

Most SIMs have been updated with a reasonable argument, but a few exceptions just pass NULL for now. This argument isn't used yet and the newbus integration likely won't be ready until after 7.0-RELEASE. 2007-04-15T08:49:19Z Scott Long scottl@FreeBSD.org 2007-04-15T08:49:19Z urn:sha1:2b83592fdcb9e7c201677f3605b9e8738a6b0737 use to synchornize and protect all data objects that are used for that SIM. Drivers that are not yet MPSAFE register Giant and operate as usual. RIght now, no drivers are MPSAFE, though a few will be changed in the coming week as this work settles down. The driver API has changed, so all CAM drivers will need to be recompiled. The userland API has not changed, so tools like camcontrol do not need to be recompiled. 2007-04-01T16:55:31Z Alexander Leidinger netchild@FreeBSD.org 2007-04-01T16:55:31Z urn:sha1:02da6fa1900e70497e825966cd8b63e9406c099e Found by: Coverity Prevent (tm) CID: 1066 2007-02-23T12:19:07Z Paolo Pisati piso@FreeBSD.org 2007-02-23T12:19:07Z urn:sha1:ef544f631226436ef590825881e7a28369df82f6 bus_setup_intr() o add an int return code to all fast handlers o retire INTR_FAST/IH_FAST For more info: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=465712+0+current/freebsd-current Reviewed by: many Approved by: re@ 2006-12-11T18:28:31Z Matt Jacob mjacob@FreeBSD.org 2006-12-11T18:28:31Z urn:sha1:b3d93fd0c96f430027eae8ba39f975341cec1648 PR: 106543 MFC after: 3 days 2006-11-02T00:54:38Z Matt Jacob mjacob@FreeBSD.org 2006-11-02T00:54:38Z urn:sha1:bd3fd815a7fbc96f1506dfdcac840b94cff28d00 as the default.
