Add ELD versions according to HDA Specification v1.0a. 2 indicates version 2, which supports CEA_Ver 861D or below. Maximum Baseline ELD size of 80 bytes (15 SAD count). 31 indicates an ELD that has been partially populated through implementation specific mean of default programming before an external graphics driver is loaded. Only the field that is called out as "canned" field will be populated, and audio driver should ignore the non "canned" field.

2015-04-07drm: Use kref_put_mutex in drm_gem_object_unreference_unlockedMaarten Lankhorst1-6/+8
If kref_put_mutex returns true then the caller or the put function is responsible for unlocking the mutex. The usual pattern assumes that the free callback unlocks the mutex, but since that is shared with the locked variant we need to explicitly unlock here.

So change it to 'DRM_IOCTL_NR(DRM_IOCTL_##ioctl) - DRM_COMMAND_BASE' which means the DRM_IOCTL_NR() now makes sense, and also this also means if there's a mistake in the DRM_IOCTL_##ioctl macros we might get a warning about it (eg. we would have gotten a sparse warning about the i915 colorkey get/set ioctl being defined to be the same thing).

To allow for views where the view type is not defined by the view type only, like it is in stereo or rotated 90 degree view, change the semantic to require the whole view structure for comparison when we match a GGTT view.

(Daniel Vetter) - Do not use potentially slower comparison when we only want to know if something is or is not a normal view. - Rebase on top of rotated view patches.

2015-03-27drm/i915: Finish gen6/7 dynamic page table allocationMichel Thierry2-19/+129
This patch continues on the idea from "Track GEN6 page table usage". From here on, in the steady state, PDEs are all pointing to the scratch page table (as recommended in the spec). When an object is allocated in the VA range, the code will determine if we need to allocate a page for the page table. Similarly when the object is destroyed, we will remove, and free the page table pointing the PDE back to the scratch page. Following patches will work to unify the code a bit as we bring in GEN8 support. GEN6 and GEN8 are different enough that I had a hard time to get to this point with as much common code as I do. The aliasing PPGTT must pre-allocate all of the page tables. There are a few reasons for this. Two trivial ones: aliasing ppgtt goes through the ggtt paths, so it's hard to maintain, we currently do not restore the default context (assuming the previous force reload is indeed necessary). Most importantly though, the only way (it seems from empirical evidence) to invalidate the CS TLBs on non-render ring is to either use ring sync (which requires actually stopping the rings in order to synchronize when the sync completes vs. where you are in execution), or to reload DCLV. Since without full PPGTT we do not ever reload the DCLV register, there is no good way to achieve this. The simplest solution is just to not support dynamic page table creation/destruction in the aliasing PPGTT. We could always reload DCLV, but this seems like quite a bit of excess overhead only to save at most 2MB-4k of memory for the aliasing PPGTT page tables. v2: Make the page table bitmap declared inside the function (Chris) Simplify the way scratching address space works. Move the alloc/teardown tracepoints up a level in the call stack so that both all implementations get the trace. v3: Updated trace event to spit out a name v4: Aliasing ppgtt is now initialized differently (in setup global gtt) v5: Rebase to latest code. Also removed unnecessary aliasing ppgtt check for trace, as it is no longer possible after the PPGTT cleanup patch series of a couple of months ago (Daniel). v6: Implement changes from code review (Daniel): - allocate/teardown_va_range calls added. - Add a scratch page allocation helper (only need the address). - Move trace events to a new patch. - Use updated mark_tlbs_dirty. - Moved pt preallocation for aliasing ppgtt into gen6_ppgtt_init. v7: teardown_va_range removed (Daniel). In init, gen6_ppgtt_clear_range call is only needed for aliasing ppgtt. v8: Rebase after s/page_tables/page_table/. v9: Remove unnecessary scratch flag in page_table struct, future patches can just compare against ppgtt->scratch_pt, and alloc_pt_scratch becomes redundant. Initialize scratch_pt and pt. (Mika) v10: Clean up aliasing ppgtt init error path and prevent leaking the ppgtt obj when init fails. (Mika) Updated commit author.

2015-03-27drm/i915: Prevent out of range pt in gen6_for_each_pdeMichel Thierry1-3/+3
Found by static analysis tool, this was harmless as the pt was not used out of scope though. Introduced by commit 678d96fbb3b5995a2fdff2bca5e1ab4a40b7e968 ("drm/i915: Track GEN6 page table usage").

2015-03-27drm/i915: fix definition of the DRM_IOCTL_I915_GET_SPRITE_COLORKEY ioctlTommi Rantala1-1/+1
Fix definition of the DRM_IOCTL_I915_GET_SPRITE_COLORKEY ioctl, so that it is different from the DRM_IOCTL_I915_SET_SPRITE_COLORKEY ioctl. Note that this is just for accuracy, the ioctl implementation itself is totally unused and already ripped out. Signed-off-by: Tommi Rantala <tt.rantala@gmail.com> [danvet: Add note that this is a dead ioctl.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-03-27drm/i915: Rip out GET_SPRITE_COLORKEY ioctlDaniel Vetter3-27/+1
It's completely unused and Tommi noticed that the #define is borked since forever. I've done a git search in userspace and only found broken definitions and no users anywhere. Cc: Tommi Rantala <tt.rantala@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2015-03-27watchdog: imgpdc: Fix default heartbeatJames Hogan1-3/+3
The IMG PDC watchdog driver heartbeat module parameter has no default so it is initialised to zero. This results in the following warning during probe: imgpdc-wdt 2006000.wdt: Initial timeout out of range! setting max timeout The module parameter description implies that the default value should be PDC_WDT_DEF_TIMEOUT, which isn't yet used, so initialise it to that. Also tweak the heartbeat module parameter description for consistency.

2015-03-27watchdog: imgpdc: Fix probe NULL pointer dereferenceJames Hogan1-1/+1
The IMG PDC watchdog probe function calls pdc_wdt_stop() prior to watchdog_set_drvdata(), causing a NULL pointer dereference when pdc_wdt_stop() retrieves the struct pdc_wdt_dev pointer using watchdog_get_drvdata() and reads the register base address through it. Fix by moving the watchdog_set_drvdata() call earlier, to where various other pdc_wdt->wdt_dev fields are initialised.

2015-03-27watchdog: mtk_wdt: signedness bug in mtk_wdt_start()Dan Carpenter1-1/+1
"ret" should be signed for the error handling to work correctly. This doesn't matter much in real life since mtk_wdt_set_timeout() always succeeds.
