2014-04-18drm/cirrus: use drm_set_preferred_modeGerd Hoffmann
commit 121a6a17439b000b9699c3fa876636db20fa4107 upstream. Explicitly set 1024x768 as default mode, so the display doesn't come up with the largest supported mode. While being at it drop first three drm_add_modes_noedid calls. As drm_add_modes_noedid fills the mode list with modes from the database *up to* the specified size it is pretty pointless to call it multiple times with different sizes.

commit 3cf70dafd7bbbc91df0a9ecb081d46f9f3d867f6 upstream. New helper function to set the preferred video mode. Can be called after drm_add_modes_noedid if you don't want the largest supported video mode be used by default.

2014-04-18drm: Prefer noninterlace cmdline mode unless explicitly specifiedTakashi Iwai
commit c683f427bdc43525f61e26609d34e799e7ea4c12 upstream. Currently drm_pick_cmdline_mode() doesn't care about the interlace when the given mode line has no "i" suffix. That is, when there are multiple entries for the same resolution, an interlace mode might be picked up just depending on the assigned order, and there is no way to exclude it. This patch changes the logic for the mode selection, to prefer the noninterlace mode unless the interlace mode is explicitly given. When no matching mode is found, it still tries the interlace mode as fallback.

2014-04-18drm/i915: Undo the PIPEA quirk for i845Chris Wilson
commit a4945f9522d27e1e6d64a02ad055e83768cb0896 upstream. The PIPEA quirk is specifically for the issue with the PIPEB PLL on 830gm being slaved to the PIPEA PLL, and so to use PIPEB requires PIPEA running. i845 doesn't even have the second PLL or pipe, and enabling the quirk results in a blank DVO LVDS.

2014-04-03drm/nouveau: make vga_switcheroo code depend on VGA_SWITCHEROOJeff Mahoney
commit d0ce7b8567ae76b8a6c0eb8361d121deb98c1b3f upstream. Commit 8116188fdef594 ("nouveau/acpi: hook up to the MXM method for mux switching.") broke the build on non-x86 architectures due to the new dependency on MXM and MXM being an x86 platform driver. It built previously since the vga switcheroo registration routines were zereod out on !X86. The code was built in but unused. This patch makes all of the DSM code depend on CONFIG_VGA_SWITCHEROO, allowing it to build on non-x86 and shrinking the module size as well.

2014-03-22drm/radeon: TTM must be init with cpu-visible VRAM, v2Lauri Kasanen
commit 14eedc32a3c0ec9dd70448a73763ee21feae3111 upstream. Without this, a bo may get created in the cpu-inaccessible vram. Before the CP engines get setup, all copies are done via cpu memcpy. This means that the cpu tries to read from inaccessible memory, fails, and the radeon module proceeds to disable acceleration. Doing this has no downsides, as the real VRAM size gets set as soon as the CP engines get init.

commit 6ab11a2635ce988ebc2e798947beb72cf7324119 upstream. At least drm/i915 expects that the obj->dev pointer is set even in failure paths. Specifically when the shmem initialization fails we call i915_gem_object_free which needs to deref obj->base.dev to get at the slab pointer in the device private structure. And the shmem allocation can easily fail when userspace is hitting open file limits. Doing the structure init even when the shmem file allocation fails prevents this Oops.

commit 372fbb8e3927fc76b0f842d8eb8a798a71d8960f upstream. Currently we report through our error state only the rings that have been initialised (as detected by ring->obj). This check is done after the GPU reset and ring re-initialisation, which means that the software state may not be the same as when we captured the hardware error and we may not print out any of the vital information for debugging the hang.

2014-02-13drm/i915: Fix the offset issue for the stolen GEM objectsAkash Goel
commit ec14ba47791965d2c08e0a681ff44eacbf3c4553 upstream. The 'offset' field of the 'scatterlist' structure was wrongly programmed with the offset value from the base of stolen area, whereas this field indicates the offset from where the interested data starts within the first PAGE pointed to by 'scattterlist' structure. As a result when a new GEM object allocated from stolen area is mapped to GTT, it could lead to an overwrite of GTT entries as the page count calculation will go wrong, refer the function 'sg_page_count'. v2: Modified the commit message.
