drm/cache: Use wbinvd helpers

2014-12-16T07:56:55Z

When the original drm code was written there were no centralized functions for doing a coordinated wbinvd across all CPUs. Now (since 2010) there are, so use them instead of rolling a new one. v2: On x86 UP systems the wbinvd_on_all_cpus() is defined as a static inline in smp.h. We must therefore include this file so we don't get compiler errors. This error was found by 0-DAY kernel test infrastructure. We only need this for x86.

drm: Missed clflushopt in drm_clflush_virt_range

2014-06-02T07:57:31Z

With this commit: 2a0788dc9bc4 x86: Use clflushopt in drm_clflush_virt_range If clflushopt is available on the system, we use it instead of clflush in drm_clflush_virt_range. There were two calls to clflush in this function, but only one was changed to clflushopt. This patch changes the other clflush call to clflushopt.

drm: Make drm_clflush_virt_range() void*

2014-04-01T20:58:29Z

Currently drm_cflush_virt_rage() takes a char* so the caller probably has to do pointless casting to avoid compiler warnings. Make the argument void* instead to avoid such issues. v2: Use void* arithmetic (Chris) Signed-off-by: Ville Syrjälä Reviewed-by: Chris Wilson Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

lib/scatterlist: sg_page_iter: support sg lists w/o backing pages

2013-03-27T16:13:44Z

The i915 driver uses sg lists for memory without backing 'struct page' pages, similarly to other IO memory regions, setting only the DMA address for these. It does this, so that it can program the HW MMU tables in a uniform way both for sg lists with and without backing pages. Without a valid page pointer we can't call nth_page to get the current page in __sg_page_iter_next, so add a helper that relevant users can call separately. Also add a helper to get the DMA address of the current page (idea from Daniel). Convert all places in i915, to use the new API.

drm: handle compact dma scatter lists in drm_clflush_sg()

2013-03-19T08:50:22Z

So far the assumption was that each scatter list entry contains a single page. This might not hold in the future, when we'll introduce compact scatter lists, so prepare for this here.

Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

2012-10-04T06:29:23Z

Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless. A few other small semantic conflicts too, noted from Dave's pre-merged branch. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits) drm/nv98/crypt: fix fuc build with latest envyas drm/nouveau/devinit: fixup various issues with subdev ctor/init ordering drm/nv41/vm: fix and enable use of "real" pciegart drm/nv44/vm: fix and enable use of "real" pciegart drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcie drm/nouveau: store supported dma mask in vmmgr drm/nvc0/ibus: initial implementation of subdev drm/nouveau/therm: add support for fan-control modes drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rules drm/nouveau/therm: calculate the pwm divisor on nv50+ drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster drm/nouveau/therm: move thermal-related functions to the therm subdev drm/nouveau/bios: parse the pwm divisor from the perf table drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devices drm/nouveau/therm: rework thermal table parsing drm/nouveau/gpio: expose the PWM/TOGGLE parameter found in the gpio vbios table drm/nouveau: fix pm initialization order drm/nouveau/bios: check that fixed tvdac gpio data is valid before using it drm/nouveau: log channel debug/error messages from client object rather than drm client drm/nouveau: have drm debugging macros build on top of core macros ...
