src/sys/powerpc/include/memdev.h, branch upstream/11.1.0 FreeBSD source tree Add reader/writer lock around mem_range_attr_get() and mem_range_attr_set(). 2011-01-17T22:58:28+00:00 Jung-uk Kim jkim@FreeBSD.org 2011-01-17T22:58:28+00:00 2fea6431120dc19a04430c68b2484524074b2e43 Compile sys/dev/mem/memutil.c for all supported platforms and remove now unnecessary dev_mem_md_init(). Consistently define mem_range_softc from mem.c for all platforms. Add missing #include guards for machine/memdev.h and sys/memrange.h. Clean up some nearby style(9) nits. MFC after: 1 month

Add a memory-range interface to /dev/mem on PowerPC using PAT attributes. 2010-10-03T16:02:53+00:00 Nathan Whitehorn nwhitehorn@FreeBSD.org 2010-10-03T16:02:53+00:00 eecadc7023154598887db6d3235e7bea39f8a5c7 Unlike actual MTRR, this only controls the mapping attributes for subsequent mmap() of /dev/mem. Nonetheless, the support is sufficiently MTRR-like that Xorg can use it, which translates into an enormous increase in graphics performance on PowerPC. MFC after: 2 weeks

Remove the unused M_MEMDEV from the kernel. 2008-06-25T07:52:10+00:00 Ed Schouten ed@FreeBSD.org 2008-06-25T07:52:10+00:00 9d7a57e9167eabcea2afbbea6d7b757f2f030680 The M_MEMDEV memory allocation pool does not seem to be used. We can live without it. Approved by: philip (mentor)

Remove the unused major/minor numbers from iodev and memdev. 2008-06-25T07:45:31+00:00 Ed Schouten ed@FreeBSD.org 2008-06-25T07:45:31+00:00 721351876cd4d3a8a700f62d2061331fa951a488 Now that st_rdev is being automatically generated by the kernel, there is no need to define static major/minor numbers for the iodev and memdev. We still need the minor numbers for the memdev, however, to distinguish between /dev/mem and /dev/kmem. Approved by: philip (mentor)
