Update the CAM API for FreeBSD 10:

2013-09-24T16:50:53Z

- Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0; MPSAFE drivers should be managing their own timeout storage. The remaining non-MPSAFE drivers have been modified to also manage their own storage, and should be considered for updating to MPSAFE (or removal) during the FreeBSD 10.x lifecycle. - Add fields related to soft timeouts and quality of service, to be used in upcoming work. - Add room for more flags in the CCB header and path_inq structures. - Begin support for extended 64-bit LUNs. - Bump the CAM version number to 0x18, but add compat shims. Tested with camcontrol and smartctl. Reviewed by: nathanw, ken, kib Approved by: re Obtained from: Netflix

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, achadd, achim MFC after: 1 day

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.

FireWire: Don't allow a tlabel to reference an xfer after free.

2013-04-08T23:16:42Z

sys/dev/firewire/firewire.c: - fw_xfer_unload(): Since we are about to free this xfer, call fw_tl_free() to remove the xfer from its tlabel's list, if it has a tlabel. - In every occasion when a xfer is removed from a tlabel's list, reset xfer->tl to -1 while holding fc->tlabel_lock, so that the xfer isn't mis-identified as belonging to a tlabel. This doesn't fix all the use-after-free problems for M_FWMEM, but is an incremental towards that goal. Reviewed by: kan, sbruno Sponsored by: Spectra Logic

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. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.
