* | drm/<drivers>: reorder framebuffer init sequenceDaniel Vetter2013-01-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | With more fine-grained locking we can no longer rely on the big mode_config lock to prevent concurrent access to mode resources like framebuffers. Instead a framebuffer becomes accessible to other threads as soon as it is added to the relevant lookup structures. Hence it needs to be fully set up by the time drivers call drm_framebuffer_init. This patch here is the drivers part of that reorg. Nothing really fancy going on safe for three special cases. - exynos needs to be careful to properly unref all handles. - nouveau gets a resource leak fixed for free: one of the error cases didn't cleanup the framebuffer, which is now moot since the framebuffer is only registered once it is fully set up. - vmwgfx requires a slight reordering of operations, I'm hoping I didn't break anything (but it's refcount management only, so should be safe). v2: Split out exynos, since it's a bit more hairy than expected. v3: Drop bogus cirrus hunk noticed by Richard Wilbur. v4: Split out vmwgfx since there's a small change in return values.

* drm/nouveau: do not forcibly power on lvds panelsBen Skeggs2013-01-13
| | | | | | | | | | | | | | This fix was put in place to fix a bug where the eDP panel on certain laptops fails to respond over the aux channel after suspend. It appears that on some systems (Dell M6600, with LVDS panel) there's a very bad interaction with the eDP init table that causes the SOR to get very confused and not drive the panel correctly, leading to bleed. A DPMS off/on cycle is enough to bring it back, but, this will avoid the problem by not touching the panel GPIOs at times we're not meant to. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | It's questionable use case, but weston/wayland already relies on this behaviour, and other drivers don't care about it, so it's a matter of compatibility. Without it, process invoking such page flip hangs in unkillable state, trying to reserve the same buffer twice.

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.

It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | This is all very much a policy thing, and hence will not belong in SW after the rework. engsw now only handles receiving the event to say "can flip now" and makes a callback to perform the actual work. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this.
