* i965/gen7_urb: Re-emit PUSH_CONSTANT_ALLOC on some gen9Nanley Chery2018-08-311-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to internal docs, some gen9 platforms have a pixel shader push constant synchronization issue. Although not listed among said platforms, this issue seems to be present on the GeminiLake 2x6's we've tested. We consider the available workarounds to be too detrimental on performance. Instead, we mitigate the issue by applying part of one of the workarounds. Re-emit PUSH_CONSTANT_ALLOC at the top of every batch (as suggested by Ken). Fixes ext_framebuffer_multisample-accuracy piglit test failures with the following options: * 6 depth_draw small depthstencil * 8 stencil_draw small depthstencil * 6 stencil_draw small depthstencil * 8 depth_resolve small * 6 stencil_resolve small depthstencil * 4 stencil_draw small depthstencil * 16 stencil_draw small depthstencil * 16 depth_draw small depthstencil * 2 stencil_resolve small depthstencil * 6 stencil_draw small * all_samples stencil_draw small * 2 depth_draw small depthstencil * all_samples depth_draw small depthstencil * all_samples stencil_resolve small * 4 depth_draw small depthstencil * all_samples depth_draw small * all_samples stencil_draw small depthstencil * 4 stencil_resolve small depthstencil * 4 depth_resolve small depthstencil * all_samples stencil_resolve small depthstencil v2: Include more platforms in WA (Ken).

* i965: Stop looking at NewDriverState when emitting 3DSTATE_URBJason Ekstrand2017-08-181-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Looking at NewDriverState is not safe in general. The state atom system is set up to ensure that new bits that get added to NewDriverState get accumulated into the set of bits used when emitting atoms but it doesn't go the other way. If we read NewDriverState, we may not get the full picture because the per-pipeline state (3D or compute) does not get added to NewDriverState before state emit is done. It's especially dangerous to do this from BLORP (either explicitly or implicitly when BLORP calls gen7_upload_urb) because that does not happen during one of the normal state upload paths. This commit solves the problem by whacking all of the per-shader-stage URB sizes to zero whenever we change the total URB size. We still have to flag BRW_NEW_URB_SIZE to ensure that the gen7_urb atom triggers but the actual decision in gen7_upload_urb can now be based entirely on URB sizes rather than on state atoms. This also makes BLORP correct because it just asks for a new URB config whenever the vsize is too small and so any change to the total URB size will trigger blorp to re-emit as well because 0 < vs_entry_size.

* i965: Stop re-uploading push constants after URB reconfiguration.Kenneth Graunke2017-07-131-1/+5
| | | | | | | | | | | Previously we would re-upload the constant data to the batchbuffer, then re-emit the packets. We only need to do the last step (causing the existing data in the batchbuffer to be re-uploaded to the push constant staging area in the L3).

* i965/urb: Trigger upload_urb on NEW_BLORPJason Ekstrand2017-07-131-1/+2
| | | | | | | | | | | | | | | It's a bit rare, but blorp can trigger a urb reconfiguration. When that happens, we need to re-upload the URB config. Previoulsy blorp would set BRW_NEW_URB_SIZE, but this is a pretty big hammer as it would cause back-to-black blorp operations to reconfigure both times. Using BRW_NEW_BLORP is a small, more accurate hammer. v2 (idr): Sort BRW_NEW_ tokens to match brw_recalculate_urb_fence and gen6_urb. v3 (idr): Don't whack BRW_NEW_URB_SIZE in blorp.

| | | | | | | | | | | | | | | | Cherryview/Broxton annoyingly have a minimum number of VS URB entries of 34, which is not a multiple of 8. When the VS size is less than 9, the number of VS entries has to be a multiple of 8. Notably, BLORP programmed the minimum number of VS URB entries (34), with a size of 1 (less than 9), which is invalid. It seemed like this could be a problem in the regular URB code as well, so I went ahead and updated that to be safe.

| | | | | | | | | | | | | | | | | | | | | | | | For several reasons, I don't think it's particularly useful to have separate flags: 1. Most of the time, tessellation shaders are paired, so both will be replaced at the same time. 2. The data layout is tightly coupled. Both need to agree on the number of per-patch slots in the VUE map. Even adding extra TCS outputs that aren't read by the TES will trigger the need for recompiles. 3. The TCS is optional from an API perspective, but required by the hardware whenever tessellation is enabled. So, atoms that deal with the TCS must check brw->tess_eval_program (BRW_NEW_TESS_EVAL_PROGRAM?) rather than brw->tess_ctrl_program to tell whether tessellation is enabled. So, not only is it unlikely to be useful, it's a bit confusing to get right. Simply using one flag for both simplifies this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we've moved a bunch of CACHE_NEW_* bits to BRW_NEW_*, the only ones that are left are legitimately related to the program cache. Yet, it seems a bit wasteful to have an entire bitfield for only 7 bits. State upload is one of the hottest paths in the driver. For each atom in the list, we call check_state() to see if it needs to be emitted. Currently, this involves comparing three separate bitfields (mesa, brw, and cache). Consolidating the brw and cache bitfields would save a small amount of CPU overhead per atom. Broadwell, for example, has 57 state atoms, so this small savings can add up. CACHE_NEW_*_PROG covers the brw_*_prog_data structures, as well as the offset into the program cache BO (prog_offset). Since most uses refer to brw_*_prog_data, I decided to use BRW_NEW_*_PROG_DATA as the name. Removing "cache" completely is a bit painful, so I decided to do it in several patches for easier review, and to separate mechanical changes from manual ones. This one simply renames things, and was made via: $ for file in *.[ch]; do sed -i -e 's/CACHE_NEW_\([A-Z_\*]*\)_PROG/BRW_NEW_\1_PROG_DATA/g' \ -e 's/BRW_NEW_WM_PROG_DATA/BRW_NEW_FS_PROG_DATA/g' $file done Note that BRW_NEW_*_PROG_DATA is still in .cache, not .brw!
