This spinlock only served debugging purposes in a time when we could not be sure of the mutex ever being released upon a GPU hang. As we now should be able rely on hangcheck to do the job for us (and that error reporting should not itself require the struct mutex) we can kill the incomplete attempt at protection.

We have no idea why we request a SyncFlush via INSTPM at that point in time -- we certainly never check for its completion... Signed-off-by: -

Alexander reported that the compilation of intel_overlay.c was failing due to an inclusion that was only valid with CONFIG_DEBUG_FS. As the whole error reporting is only useful with debugfs enabled, remove all the redundant error state collection code when compiling without CONFIG_DEBUG_FS. Reported-by:

Slightly easier to follow than the state machine and now possible as the control structure is opaque and hw_wedged is no longer interferred with. Signed-off-by:

During DPMS we currently do not want the overlay code to be interruptible, so pass that information down and only take the uninterrruptible paths. Signed-off-by:

On i830, there exists a bug where an overlay on pipe B requires the mode clock on pipe A in order to activate. So workaround this by activating pipe A when trying to enable the overlay on pipe B.

By allocating the request prior to writing to the ringbuffer, we can abort the operation without leaving the GPU in an inconsistent state. Signed-off-by:

Inline the call to wait_flip() and simplify the resulting code. Signed-off-by:

We can program the h/w to first wait on the flip and then switch off without relying on s/w intervention. This removes the need for a double step switch off, bringing much rejoicing. Signed-off-by:

The only time where an atomic mapping is required is during error-capture and there we cannot use the default slot, but need to specifically use one of the IRQ slots. So separate out the two conditions and use the atomic mapping only when appropriate. Signed-off-by:

... take advantage of the new implicit request issuing of i915_wait_request. Signed-off-by:

Daniel Vetter authored
One caller (for the pageflip support) wants a purely pipelined flush. Distinguish this case by a new parameter. This will also be useful later on for pipelined fencing. v2: Simplify the code by depending upon the implicit request emitting of i915_wait_request. Signed-off-by:

By moving one i915_add_request we can solely depend on the new auto-seqno-numbering behaviour. Signed-off-by:

i915_gem_object_move_to_active can handle zero seqno for us now. And not emitting a request is not fatal here - we'll try to emit a new one if we have to wait for some rendering to complete. In case this assumption ever gets accidentally broken, there's already a BUG_ON to catch it in i915_do_wait_request. So just silently ignore ENOMEM here instead of screwing up the whole drm.

... instead of threading flush_domains through the execbuf code to i915_add_request. With this change 2 small cleanups are possible (likewise the majority of the patch): - The flush_domains parameter of i915_add_request is always 0. Drop it and the corresponding logic. - Ditto for the seqno param of i915_gem_process_flushing_list. Signed-off-by:

Previously I thought that one interrupt per batchbuffer should be enough. Now tedious benchmarking showed this to be wrong. Therefore track whether any commands have been isssued with a future seqno (like pipelined fencing changes or flushes). If this is the case emit a request before issueing the batchbuffer.

Now that we can move objects to the active list without already having emitted a request, move the flushing list handling into i915_gem_flush. This makes more sense and allows to drop a few i915_add_request calls that are not strictly necessary. Signed-off-by:

Sometimes (like when flushing in preparation of batchbuffer execution) we know that we'll emit a request but haven't yet done so. Allow this case by simply taking the next seqno by default. Ensure that a request is eventually emitted before waiting for an request by issuing it in i915_wait_request iff this is not yet done. Also replace one open-coded version of i915_gem_object_wait_rendering, to prevent future code-diversion. Chris Wilson asked me to explain and clarify what this patch does and why. Here it goes: Old way of moving objects onto the active list and associating them with a reques: 1. i915_add_request + store the returned seqno somewhere 2. i915_gem_object_move_to_active (with the stored seqno as parameter) For the current users, this is all fine. But I'd like to associate objects (and fence regs) with the batchbuffer request deep down in the execbuf call-chain. I thought about three ways of implementing this. a) Don't care, just emit request when we need a new seqno. When heavily pipelining fence reg changes, this would have caused tons of superflous request (and corresponding irqs). b) Thread all changed fences, objects, whatever through the execbuf-maze, so that when we emit a request, we can store the new seqno at all the right places. c) Kill that seqno-threading-around business by simply storing the next seqno, i.e. allow 2. to be done before 1. in the above sequence. I've decided to implement c) (in this patch). The following patches are just fall-out that resulted from this small conceptual change. * We can handle the flushing list processing where we actually emit a flush (i915_gem_flush and i915_retire_commands) instead of in i915_add_request. The code makes IMHO more sense this way (and i915_add_request looses the flush_domains parameter, obviously). * We can avoid emitting unnecessary requests. IMHO there's no point in emitting more than one request per batchbuffer (with or without an corresponding irq). * By enforcing 2. before 1. ordering in the above sequence the seqno argument of i915_gem_object_move_to_active is redundant and can be dropped. v2: Now i915_wait_request issues request if it is not yet emitted. Also introduce i915_gem_next_request_seqno(dev) just in case we ever need to do some prep work before using a new seqno. Signed-off-by:
