While the exynos DRM support in principle can work on multiplatform, the FIMD and IPP sections of it both include the plat/map-base.h header file, which is not available on multiplatform. Rather than disabling the entire driver, we can just conditionally build these two parts.

Fortunately, that header file is not required any more here, so we can simply revert the inclusion in order to build the ARM allyesconfig again without getting this error: drivers/gpu/drm/exynos/exynos_hdmi.c:37:27: fatal error: plat/gpio-cfg.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

2013-01-25drm/exynos: consider DMA_NONE flag to dmabuf importInki Dae
This patch considers DMA_NONE flag for other drivers not using dma mapping framework with iommu such as 3d gpu driver or others. For example, there might be 3d gpu driver that has its own iommu hw unit and iommu table mapping mechnism. So in this case, the dmabuf buffer imported into this driver needs just only sg table to map the buffer with its own iommu table itself. So this patch makes dma_buf_map_attachment ignore dma_map_sg call and just return sg table containing pages if dma_data_direction is DMA_NONE.

2013-01-23drm/radeon: fix a rare case of double kfreeIlija Hadzic
If one (but not both) allocations of p->chunks[].kpage[] in radeon_cs_parser_init fail, the error path will free the successfully allocated page, but leave a stale pointer value in the kpage[] field. This will later cause a double-free when radeon_cs_parser_fini is called. This patch fixes the issue by forcing both pointers to NULL after kfree in the error path. The circumstances under which the problem happens are very rare. The card must be AGP and the system must run out of kmalloc area just at the right time so that one allocation succeeds, while the other fails.

DMAR support on g4x/gm45 integrated gpus seems to be totally busted. So don't bother, but instead disable it by default to allow distros to unconditionally enable DMAR support. v2: Actually wire up the right quirk entry, spotted by Adam Jackson. Note that according to intel marketing materials only g45 and gm45 support DMAR/VT-d. So we have reports for all relevant gen4 pci ids by now. Still, keep all the other gen4 ids in the quirk table in case the marketing stuff confused me again, which would not be the first time.

2013-01-23drm/i915: GFX_MODE Flush TLB Invalidate Mode must be '1' for scanline waitsChris Wilson
On SNB, if bit 13 of GFX_MODE, Flush TLB Invalidate Mode, is not set to 1, the hardware can not program the scanline values. Those scanline values then control when the signal is sent from the display engine to the render ring for MI_WAIT_FOR_EVENTs. Note setting this bit means that TLB invalidations must be performed explicitly through the appropriate bits being set in PIPE_CONTROL.

While working on a new kms driver that uses memcpy, if I overallocated bo's up to the memory limits, and eviction failed, then machine would oops soon after due to having an active bo with an already freed drm_mm embedded in it, freeing it a second time didn't end well.

2013-01-17drm/i915: fix FORCEWAKE posting readsJani Nikula
We stopped reading FORCEWAKE for posting reads in commit 8dee3eea3ccd3b6c00a8d3a08dd715d6adf737dd Author: Ben Widawsky <ben@bwidawsk.net> Date: Sat Sep 1 22:59:50 2012 -0700 drm/i915: Never read FORCEWAKE and started using something from the same cacheline instead. On the bug reporter's machine this broke entering rc6 states after a suspend/resume cycle. It turns out reading ECOBUS as posting read worked fine, while GTFIFODBG did not, preventing RC6 states after suspend/resume per the bug report referenced below. It's not entirely clear why, but clearly GTFIFODBG was nowhere near the same cacheline or address range as FORCEWAKE. Trying out various registers for posting reads showed that all tested registers for which NEEDS_FORCE_WAKE() (in i915_drv.c) returns true work. Conversely, most (but not quite all) registers for which NEEDS_FORCE_WAKE() returns false do not work. Details in the referenced bug. Based on the above, add posting reads on ECOBUS where GTFIFODBG was previously relied on. In true cargo cult spirit, add posting reads for FORCEWAKE_VLV writes as well, but instead of ECOBUS, use FORCEWAKE_ACK_VLV which is in the same address range as FORCEWAKE_VLV. v2: Add more details to the commit message. No functional changes.

2013-01-16drm/i915: Invalidate the relocation presumed_offsets along the slow pathChris Wilson
In the slow path, we are forced to copy the relocations prior to acquiring the struct mutex in order to handle pagefaults. We forgo copying the new offsets back into the relocation entries in order to prevent a recursive locking bug should we trigger a pagefault whilst holding the mutex for the reservations of the execbuffer. Therefore, we need to reset the presumed_offsets just in case the objects are rebound back into their old locations after relocating for this exexbuffer - if that were to happen we would assume the relocations were valid and leave the actual pointers to the kernels dangling, instant hang.

2013-01-13drm/nvc0/fb: fix crash when different mutex is used to protect same listAleksi Torhamo
Fixes regression introduced in commit 861d2107 "drm/nouveau/fb: merge fb/vram and port to subdev interfaces" nv50_fb_vram_{new,del} functions were changed to use nouveau_subdev->mutex instead of the old nouveau_mm->mutex. nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't have its own fb_vram_del function, using nv50_fb_vram_del instead. Because of this, on nvc0 a different mutex ends up being used to protect additions and deletions to the same list. This patch is a -stable candidate for 3.7.

2013-01-13drm/nouveau/clock: fix support for more than 2 monitors on nve0Aleksi Torhamo
Fixes regression introduced in commit 70790f4f "drm/nouveau/clock: pull in the implementation from all over the place" When code was moved from nv50_crtc_set_clock to nvc0_clock_pll_set, the PLLs it is used for got limited to only the first two VPLLs. nv50_crtc_set_clock was only called to change VPLLs, so it didn't limit what it was used for in any way. Since nvc0_clock_pll_set is used for all PLLs, it has to specify which PLLs the code is used for, and only listed the first two VPLLs.

2013-01-13drm/nv50/disp: fix selection of bios script for analog outputsMarcin Slusarz
Analog output number was overwritten by value from digital output path. Fix it. Fixes resume from s2ram: https://bugs.freedesktop.org/show_bug.cgi?id=58729 (as stumbled on by J Binder, Pontus Fuchs and me) Fixes blank screen on module load (reported by Sune Mølgaard). Fixes regression from commit 186ecad21c854385823a430b1402053ae7fd59dc ("drm/nv50/disp: move remaining interrupt handling into core").

2013-01-13drm/nv17-50: restore fence buffer on resumeMarcin Slusarz
Since commit 5e120f6e4b3f35b741c5445dfc755f50128c3c44 "drm/nouveau/fence: convert to exec engine, and improve channel sync" nouveau fence sync implementation for nv17-50 and nvc0+ started to rely on state of fence buffer left by previous sync operation. But as pinned bo's (where fence state is stored) are not saved+restored across suspend/resume, we need to do it manually. nvc0+ was fixed by commit d6ba6d215a538a58f0f0026f0961b0b9125e8042 "drm/nvc0/fence: restore pre-suspend fence buffer context on resume".

2013-01-13drm/nouveau: fix blank LVDS screen regression on pre-nv50 cardsMarcin Slusarz
Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate from create/destroy") started to call display init routines on pre-nv50 hardware on module load. But LVDS init code sets driver state in a way which prevents modesetting code from operating properly. nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to NV_DPMS_CLEARED. drm_crtc_helper_set_mode nv04_dfp_prepare nv04_lvds_dpms(DRM_MODE_DPMS_OFF) nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too, so it skips calling some crucial lvds scripts.
