* i965: Prefer Meta over the BLT for BlitFramebuffer.Kenneth Graunke2015-02-171-7/+7
| | | | | | | | | | | | | | | | | There's some debate about whether we should use Meta or BLORP, but either should run circles around the BLT engine. In particular, this means that Gen8+ will use the 3D engine for blits, like we do on Gen6-7. Improves performance in "copypixrate -blit -back" (from Mesa demos) by 232.037% +/- 3.15795% (n=10) on Broadwell GT3e. v2: Rebase on Laura's changes.

* i965: Allow exec_list sentinels as arguments to insert functions.Matt Turner2015-02-171-2/+4
| | | | | | | | | | | | | | | | | | To insert an instruction at the end of a basic block, we typically do something like inst = block->last_non_control_flow_inst(); inst->insert_after(block, new_inst); But blocks can consist of a single control flow instruction, so inst will actually be the exec_list's head sentinel. We shouldn't use it as if it were a regular instruction, but it is safe to insert something after it. This patch avoids assert-failing because an exec_list sentinel wasn't in the basic block's instruction list. Reviewed-by: Kenneth Graunke <[email protected]>

* glsl: Reduce memory consumption of copy propagation passes.Kenneth Graunke2015-02-172-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | opt_copy_propagation and opt_copy_propagation_elements create new ACP and Kill sets each time they enter a new control flow block. For if blocks, they also copy the entire existing ACP set contents into the new set. When we exit the control flow block, we discard the new sets. However, we weren't freeing them - so they lived on until the pass finished. This can waste a lot of memory (57MB on one pessimal shader). This patch makes the pass allocate ACP entries using this->acp as the memory context, and Kill entries out of this->kill. It also steals kill entries when moving them from the inner kill list to the parent. It then frees the lists, including their contents. v2: Move ralloc_free(this->acp) just before this->acp = orig_acp (suggested by Eric Anholt).

* i965: Do Sandybridge workaround flushes before each primitive.Kenneth Graunke2015-02-1711-84/+20
| | | | | | | | | | | | | | | | | | | | | | | Sandybridge requires the post-sync non-zero workaround in a ton of places, and if you ever miss one, the GPU usually hangs. Currently, we try to track exactly when a workaround flush is necessary (via the brw->batch.need_workaround_flush flag). This is tricky to get right, and we've botched it several times in the past. This patch unconditionally performs the post-sync non-zero flush at the start of each primitive's state upload (including BLORP). We drop the needs_workaround_flush flag, and drop all the other callers, as the flush has already been performed. We have no data to indicate that simply flushing all the time will hurt performance, and it has the potential to help stability. v2: Add post-sync workaround to initial GPU state upload to be extra cautious (suggested by Chad Versace).

* i965/simd8vs: Fix SIMD8 atomicsBen Widawsky2015-02-161-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The short version: we need to set bits in R0.7 which provide a mask to be used for PS kill samples/pixels. Since the VS has no such concept, we just need to set all 1. The longer version... Execution for SIMD8 atomics is defined as follows: SIMD8: The low 8 bits of the execution mask are ANDed with 8 bits of the Pixel/Sample Mask from the message header. For the typed messages, the Slot Group in the message descriptor selects either the low or high 8 bits. For the untyped messages, the low 8 bits are always selected. The resulting mask is used to determine which slots are read into the destination GRF register (for read), or which slots are written to the surface (for write). If the header is not present, only the low 8 bits of the execution mask are used. The message header for untyped messages is defined in R0.7 "This field contains the 16-bit pixel/sample mask to be used for SIMD16 and SIMD8 messages. All 16 bits are used for SIMD16 messages. For typed SIMD8 messages, Slot Group selects which 8 bits of this field are used. For untyped SIMD8 messages, the low 8 bits of this field are used." Furthermore, "The message header for the untyped messages only needs to be delivered for pixel shader threads, where the execution mask may indicate pixels/samples that are enabled only due to derivative (LOD) calculations, but the corresponding slot on the surface must not be accessed." We're not using a pixel shader here, but AFAICT, this mask is used for all stages. This leaves two options, Remove the header, or make the VS code emit the correct thing for the header. I believe one of the goals of using SIMD8 VS was to get as much code reuse as possible, and so I chose the latter. Since the VS has no such thing as kill instructions, the mask is derived simple as all 1's. v2: Add a comment to the code (stolen from Curro on the mailing list) Change the control flow style (Curro + Jason) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=87258 Cc: Kristian Høgsberg <[email protected]> Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Francisco Jerez <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

* meta: Fix saving the results of the current occlusion queryNeil Roberts2015-02-161-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | When restoring the current state in _mesa_meta_end it was previously trying to copy the on-going sample count of the current occlusion query into the new query after restarting it so that the driver will continue adding to the previous value. This wouldn't work for two reasons. Firstly, the query might not be ready yet so the Result member will usually be zero. Secondly the saved query is stored as a pointer to the query object, not a copy of the struct, so it is actually restarting the exact same object. Copying the result value is just copying between identical addresses with no effect. The call to _mesa_BeginQuery will have always reset it back to zero. This patch fixes it by making it actually wait for the query object to be ready before grabbing the previous result. The downside of doing this is that it could introduce a stall but I think this situation is unlikely so it might not matter too much. A better solution might be to introduce a real suspend/resume mechanism to the driver interface. This could be implemented in the i965 driver by saving the depth count multiple times like it does in the i945 driver.
