SVN rev 227309 on 2011-11-07 15:43:11Z by ed Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs. The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

We remove writeback of the original buffer size from bus_dmamem_alloc() and add appropriate L1/L2 flush operation. b) missing write-back invalidate operation In pmap_kremove a page is removed so we must do a write-back invalidate operation aligned to the page virtual address.

SVN rev 188350 on 2009-02-08 22:54:58Z by imp When bouncing pages, allow a new option to preserve the intra-page offset. This is needed for the ehci hardware buffer rings that assume this behavior. This is an interim solution, and a more general one is being worked on. This solution doesn't break anything that doesn't ask for it directly. The mbuf and uio variants with this flag likely don't work and haven't been tested. Universe builds with these changes. I don't have a huge-memory machine to test these changes with, but will be happy to work with folks that do and hps if this changes turns out not to be sufficient.

Honor maxsegsz of less than a page size in a DMA tag. Previously it used to return PAGE_SIZE without respect to restrictions of a DMA tag. This affected all of the busdma load functions that use _bus_dmamap_loader_buffer() as their back-end. Reviewed by: scottl

If our buffer is not aligned on the cache line size, write back/invalidate the first and last cache line in PREREAD, and just invalidate the cache lines in POSTREAD, instead of write-back/invalidating in POSTREAD, which could lead to stale data overriding what has been transfered by DMA.

Try to honor BUS_DMA_COHERENT : if the flag is set, normally allocate memory with malloc() or contigmalloc() as usual, but try to re-map the allocated memory into a VA outside the KVA, non-cached, thus making the calls to bus_dmamap_sync() for these buffers useless.

netchild's mega-patch to isolate compiler dependencies into a central place. This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

Fix a problem with tag->boundary inheritence that has existed since day one and was propagated to nearly every platform. The boundary of the child needs to consider the boundary of the parent and pick the minimum of the two, not the maximum. However, if either is 0 then pick the appropriate one. This bug was exposed by a recent change to ATA, which should now be fixed by this change. The alignment and maxsegsz tag attributes likely also need a similar review in the near future. This is a MT5 candidate. Reviewed by: marcel Submitted by: sos (in part)
