Things like reliable GGTT mappings and mirrored 2d-on-3d display will need to map objects into the same address space multiple times. Added a GGTT view concept and linked it with the VMA to distinguish between multiple instances per address space. New objects and GEM functions which do not take this new view as a parameter assume the default of zero (I915_GGTT_VIEW_NORMAL) which preserves the previous behaviour. This now means that objects can have multiple VMA entries so the code which assumed there will only be one also had to be modified. Alternative GGTT views are supposed to borrow DMA addresses from obj->pages which is DMA mapped on first VMA instantiation and unmapped on the last one going away. v2: * Removed per view special casing in i915_gem_ggtt_prepare / finish_object in favour of creating and destroying DMA mappings on first VMA instantiation and last VMA destruction. (Daniel Vetter) * Simplified i915_vma_unbind which does not need to count the GGTT views. (Daniel Vetter) * Also moved obj->map_and_fenceable reset under the same check. * Checkpatch cleanups. v3: * Only retire objects once the last VMA is unbound. v4: * Keep scatter-gather table for alternative views persistent for the lifetime of the VMA. * Propagate binding errors to callers and handle appropriately. v5: * Explicitly look for normal GGTT view in i915_gem_obj_bound to align usage in i915_gem_object_ggtt_unpin. (Michel Thierry) * Change to single if statement in i915_gem_obj_to_ggtt. (Michel Thierry) * Removed stray semi-colon in i915_gem_object_set_cache_level. For: VIZ-4544 Signed-off-by: -

So, for packets that needs to be read/write for DSI single link on Port A and Port C will now be based on the DVO port from VBT block 2, instead of seq_port. Signed-off-by:

Faster feedback to errors is always better. This is inspired by the addition to WARN_ONs to mask/enable helpers for registers to make sure callers have the arguments ordered correctly: Pretty much always the arguments are static. We use WARN_ON(1) a lot in default switch statements though where we should always handle all cases. So add a new macro specifically for that. The idea to use __builtin_constant_p is from Chris Wilson. v2: Use the ({}) gcc-ism to avoid the static inline, suggested by Dave. My first attempt used __cond as the temp var, which is the same used by BUILD_BUG_ON, but with inverted sense. Hilarity ensued, so sprinkle i915 into the name. Also use a temporary variable to only evaluate the condition once, suggested by Damien. v3: It's crazy but apparently 32bit gcc can't compile out the BUILD_BUG_ON in a lot of cases and just falls over. I have no idea why, but until clue grows just disable this nifty idea on 32bit builds. Reported by 0-day builder. v4: Got it all wrong, apparently its the gcc version. We need 4.9+. Now reported by Imre. v5: Chris suggested to add the case to MISSING_CASE for speedier debug. v6: Even some gcc 4.9 versions don't see through the maze, so give up for now. Keep the skeleton and MISSING_CASE stuff though.

Stupid userspace (there is no evil userspace in debugfs by assumption) might provoke a leak since we allocate the new array without holding any locks. Drop in an unconditional kfree to deal with this - kfree can handle NULL. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Currently i915_pipe_crc_read() will drop pipe_crc->lock for the entire duration of the copy_to_user() loop, which means it'll access pipe_crc->entries without any protection. If another thread sneaks in and frees pipe_crc->entries the code will oops. Reorganize the code to hold the lock around everything except copy_to_user(). After the copy the lock is reacquired and the the number of available entries is rechecked. Since this is a debug feature simplify the error handling a bit by consuming the crc entry even if copy_to_user() would fail. Signed-off-by:

Set the pipe_crc->entries pointer while holding the relevant spinlock. Doesn't matter too much since a spurious pipe crc interrupt would then just update one entry but later that entry would get cleared when head and tail are both set to 0. But being a bit more paranoid doesn't hurt. Signed-off-by:

To get stable CRCs from the DP CRC source we need to reset the scrambler for each frame. Enable the reset feature when grabbing CRCs for pipe C on CHV. Pipes A and B were already covered due sharing the code with VLV. We can safely extend PIPE_SCRAMBLE_RESET_MASK to deal with CHV since the extra bit was MBZ on the older platforms. Signed-off-by:

After a bit of irc discussion we've concluded that it would be prudent to check that callers use the mask/enable paramters correctly. So add a WARN_ON. Spurred by Damien's bugfix which added _MASKED_FIELD. v2: We use WARN_ON(1) a lot to catch default cases in switch blocks which should always be extended. So this doesn't work really. Dunno why gcc only started complaining when I've moved the WARN out of the static inline helper to address a feedback from Jani.

Similar to a patch from Thomas Daniel for lrc contexts. This keeps both sides somewhat in sync and should make Dave Gordon happy. Note that both the wa and the golden context init code suffer a bit from an inssuficient split into driver load and hw init code. Which means we have a bunch of tests all over the place to check whether the one-time initialization has been done already or not. All that one-tim code should be moved into the one-time ring setup code, but that's work for later.

Added the request structure's 'uniq' identifier to the trace information. Also renamed the '_complete' trace event to '_notify' as it actually happens in the IRQ 'notify_ring()' function. The intention is to add a new '_complete' trace event which occurs when a request structure is actually marked as complete. However, at the moment the completion status is re-tested every time the query is made so there isn't a completion event as such. v2: New patch added to series. v3: Rebased to remove completion caching as that is apparently contentious.

For debugging purposes, it is useful to be able to uniquely identify a given request structure as it works its way through the system. This becomes especially tricky once the seqno value is lazily allocated as then the request has nothing but its pointer to identify it for much of its life.

There is a general theory that kzmalloc is better/safer than kmalloc, especially for interesting data structures. This change updates the request structure allocation to be zero filled. This also fixes crashes in the reset code. Quoting Mika's patch: "Clean the request structure on alloc. Otherwise we might end up referencing uninitialized fields. This is apparent when we try to cleanup the preallocated request on ring reset, before any request has been submitted to the ring. The request->ctx is foobar and we end up freeing the foobarness."

The display related patches earlier in this series were edited during merge to improve the request unreferencing. Specifically, the need for de-referencing at interrupt time was removed. However, the resulting code did a 'deref(req) ; req = NULL' sequence rather than using the 'req_assign(req, NULL)' wrapper. The two are functionally equivalent, but using the wrapper is more consistent with all the other places where requests are assigned. Note that the whole point of the wrapper is that using it everywhere that request pointers are assigned means that the reference counting is done automatically and can't be accidentally forgotten about. Plus it allows simpler future maintainance if the reference counting mechanisms ever need to change. For: VIZ-4377 Signed-off-by:

If we extend the commit_plane handlers for each plane type to be able to handle fb=0, then we can easily implement plane disable via the update_plane handler. The cursor plane already works this way, and this is the direction we need to go to integrate with the atomic plane handler. We can now kill off the type-specific disable functions, as well as the redundant intel_plane_disable() (not to be confused with intel_disable_plane()). Note that prepare_plane_fb() only gets called as part of update_plane when fb!=NULL (by design, to match the semantics of the atomic plane helpers); this means that our commit_plane handlers need to handle the frontbuffer tracking for the disable case, even though they don't handle it for normal updates. v2: - Change BUG_ON to WARN_ON (Ander/Daniel) v3: - Drop unnecessary plane->crtc check since a previous patch to plane update ensures that plane->crtc will always be non-NULL, even for disable calls that might pass NULL from userspace. (Ander) - Drop a s/crtc/plane->crtc/ hunk that was unnecessary. (Ander) v4: - Fix missing whitespace (Ander) v5: - Use state's crtc rather than plane's crtc in intel_check_primary_plane(). plane->crtc could be NULL, but we've already fixed up state->crtc to ensure it's non-NULL (even if userspace passed it as NULL during a disable call).

When disabling a plane, it is legal to pass crtc = NULL. Since planes on Intel hardware are tied to a fixed CRTC, go ahead and set state->crtc to the appropriate crtc in cases where it is passed to us as NULL. In a future patch, we will start using the update handler for plane disables, so this will help ensure we always have a non-NULL crtc pointer to work with. Signed-off-by:

The 'prepare' step for all types of planes are pretty similar; consolidate the three 'prepare' functions into a single function. This paves the way for future integration with the atomic plane handlers. Note that we pull the 'wait for pending flips' functionality out of the primary plane's prepare step and place it directly in the 'setplane' code. When we move to the atomic plane handlers, this code will be in the 'atomic begin' step. v2: Update GEM fb tracking for physical cursors also (Ander) Signed-off-by:

Primary and sprite planes have already been refactored to include a 'prepare' step which handles all the commit-time operations that could fail (i.e., pinning buffers and such). Refactor the cursor commit in a similar manner. For simplicity and consistency with other plane types, we also switch to using intel_pin_and_fence_fb_obj() to perform our pinning for non-physical cursors. This will allow us to more easily migrate the code into the atomic 'begin' handler in a plane-agnostic manner in a future patchset. v2: - Update GEM fb tracking for physical cursors too. (Ander) - Use intel_unpin_fb_obj() rather than i915_gem_object_unpin_from_display_plane() and do so while holding struct_mutex. (Ander) - Update plane->fb in commit_cursor_plane. This isn't really necessary since the DRM core does this for us in __setplane_internal(), but doing it in our driver once we know we're going to succeed helps avoid confusion. (Ander) Signed-off-by:
