Currently object size is returned for the rotated VMA size which can be bigger than the rotated view itself. Since the binding code pads all excess size with scratch pages the only minor issue with this is wasting some GGTT space, but still feels nicer to fix and report the real size. v2: Rebase for tracking size in bytes instead of pages.

With the new DRRS code it kinda sticks out, and we never managed to get this to work well enough without causing issues. Time to wave goodbye. I've decided to keep the logic for programming the reduced clocks intact, but everything else is gone. If anyone ever wants to resurrect this we need to redo it all anyway on top of the frontbuffer tracking. Signed-off-by:

The current code tracks business across all pipes, but we're only really interested in the one pipe DRRS is enabled on. Fairly tiny optimization, but something I noticed while reading the code. But it might matter a bit when e.g. showing a video or something only on the external screen, while the panel is kept static. Also regroup the code slightly: First compute new bitmasks, then take appropriate actions. Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Durgadoss R <durgadoss.r@intel.com> Reviewed-by:

I was momentarily confused until I've double-checked that these functions really only compute state and don't update the hardware state. They once did that, but since Ander's rework of the dpll computation flow that's no longer the case. Rename them to avoid further confusion. Note that the ilk code already follows the compute_dpll naming scheme for computing the actual register value. DDI code goes with _calc_, but that is close enough.

The current/old frontbuffer might still have gpu frontbuffer rendering pending. But once flipped it won't have the corresponding frontbuffer bits any more and hence the request retire function won't ever clear the corresponding busy bits. The async flip tracking (with the flip_prepare and flip_complete functions) already does this, but somehow I've forgotten to do this for synchronous flips. Note that we don't track outstanding rendering of the new framebuffer with busy_bits since all our plane update code waits for previous rendering to complete before displaying a new buffer. Hence a new buffer will never be busy. v2: Drop the spurious inline Ville spotted. v3: Don't touch flip_bits in the synchronsou frontbuffer_flip function, noticed by Paulo. v4: Remove one more inline that slipped through (Paulo).

To initialize WA batch, at the moment we first allocate batch and then check whether we have any WA to be initialized for the given Gen; if we don't have any WA then we WARN the user, destroy the batch and return but this is causing another WARN in cleanup code complaining about sleeping in atomic context. Till we understand this better and to keep things simpler, bail out early if we don't have WA.

A bunch of the low level LRC functions were passing around ringbuf and ctx pairs. In a few cases, they took the r/c pair and a request as well. This is all quite messy and unnecesary. The context_queue() call is especially bad since the fake request code got removed - it takes a request and three extra things that must be extracted from the request and then it checks them against what it finds in the request. Removing all the derivable data makes the code much simpler all round. This patch updates those functions to just take the request structure. Note that logical_ring_wait_for_space now takes a request structure but already had a local request pointer that it uses to scan for something to wait on. To avoid confusion the local variable has been renamed 'target' (it is searching for a target request to do something with) and the parameter has been called req (to guarantee anything accidentally missed gets a compiler error). v2: Updated commit message re wait_for_space (Tomas Elf review comment).

The LRC submission code requires a request for tracking purposes. It does not actually require that request to 'complete' it simply uses it for keeping hold of reference counts on contexts and such like. Previously, the fall back path of polling for space in the ring would start by submitting any outstanding work that was sat in the buffer. This submission was not done as part of the request that that work was owned by because that would lead to complications with the request being submitted twice. Instead, a null request structure was passed in to the submit call and a fake one was created. That fall back path has long since been obsoleted and has now been removed. Thus there is never any need to fake up a request structure. This patch removes that code. A couple of sanity check warnings are added as well, just in case. For: VIZ-5115 Signed-off-by:

In _i915_add_request(), the request is associated with a userland client. Specifically it is linked to the 'file' structure and the current user process is recorded. One problem here is that the current user process is not necessarily the same as when the request was submitted to the driver. This is especially true when the GPU scheduler arrives and decouples driver submission from hardware submission. Note also that it is only in the case where the add request comes from an execbuff call that there is a client to associate. Any other add request call is kernel only so does not need to do it. This patch moves the client association into a separate function. This is then called from the execbuffer code path itself at a sensible time. It also removes the now redundant 'file' pointer from the add request parameter list. An extra cleanup of the client association is also added to the request clean up code for the eventuality where the request is killed after association but before being submitted (e.g. due to out of memory error somewhere). Once the submission has happened, the request is on the request list and the regular request list removal will clear the association. Note that this still needs to happen at this point in time because the request might be kept floating around much longer (due to someone holding a reference count) and the client should not be worrying about this request after it has been retired.

The outstanding_lazy_request is no longer used anywhere in the driver. Everything that was looking at it now has a request explicitly passed in from on high.

Now that the *_ring_begin() functions no longer call the request allocation code, it is finally safe for the request allocation code to call *_ring_begin().

Now that everything above has been converted to use requests, intel_logical_ring_begin() can be updated to take a request instead of a ringbuf/context pair. This also means that it no longer needs to lazily allocate a request if no-one happens to have done it earlier. Note that this change makes the execlist signature the same as the legacy version. Thus the two functions could be merged into a ring->begin() wrapper if required. For: VIZ-5115 Signed-off-by:
