* glsl: Prohibit illegal mixing of redeclarations inside/outside gl_PerVertex.Paul Berry2013-11-215-1/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From section 7.1 (Built-In Language Variables) of the GLSL 4.10 spec: Also, if a built-in interface block is redeclared, no member of the built-in declaration can be redeclared outside the block redeclaration. We have been regarding this text as a clarification to the behaviour established for gl_PerVertex by GLSL 1.50, so we apply it regardless of GLSL version. This patch enforces the rule by adding an enum to ir_variable to track how the variable was declared: implicitly, normally, or in an interface block. Fixes piglit tests: - gs-redeclares-pervertex-out-after-global-redeclaration.geom - vs-redeclares-pervertex-out-after-global-redeclaration.vert - gs-redeclares-pervertex-out-after-other-global-redeclaration.geom - vs-redeclares-pervertex-out-after-other-global-redeclaration.vert - gs-redeclares-pervertex-out-before-global-redeclaration - vs-redeclares-pervertex-out-before-global-redeclaration Cc: "10.0" <[email protected]> v2: Don't set "how_declared" redundantly in builtin_variables.cpp. Properly clone "how_declared".

* i965: Take "bookend" OA snapshots at the start/end of each batch.Kenneth Graunke2013-11-213-9/+379
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, our hardware only has one set of aggregating performance counters shared between all 3D programs, and their values are not saved or restored by hardware contexts. Also, at least on Sandybridge and Ivybridge, the counters lose their values if the GPU goes to sleep. To work around both of these problems, we have to snapshot the performance counters at the beginning and end of each batch, similar to how we handle query objects on platforms that don't support hardware contexts. I call these "bookend" snapshots. Since there can be multiple performance monitors active at a time, we store the bookend snapshots in a global BO, shared by all monitors. For monitors that span multiple batches, acquiring results involves adding up three segments: BeginPerfMonitor --> End of Batch 1 ("head") Start of Batch 2 --> End of Batch 2 ... ("middle") Start of Batch N-1 --> End of Batch N-1 Start of Batch N --> EndPerfMonitor ("tail") Monitors that refer to bookend BO snapshots are considered "unresolved". We delay resolving them (and adding up deltas to obtain the results) as long as possible to avoid blocking on mapping monitor->oa_bo. We can also run out of space in the bookend BO, at which point we have to resolve all unresolved monitors. Then we can throw away the snapshots and begin writing at the beginning of the buffer.

* i965: Reserve batchbuffer space for a closing MI_REPORT_PERF_COUNT.Kenneth Graunke2013-11-211-1/+7
| | | | | | | | | | | | | | | | | | | In order to use the Observability Architecture effectively, we'll need to take snapshots of the OA counters via MI_REPORT_PERF_COUNT at the start and end of each batch. Experimentation reveals that we need to flush before and after each MI_REPORT_PERF_COUNT to get working values. For simplicitly, I chose to use intel_batchbuffer_emit_mi_flush(), which unfortunately expands to triple pipe controls on Sandybridge. We may want to start computing per-generation reserved batch space to avoid the insanity of Sandybridge's PIPE_CONTROL cost. That said, much of this cost existed before I rewrote the query object support to use hardware contexts, so it's at least not entirely new.

| | | | | | | | | | | | | We need to start OA at the beginning of each batch where monitors are active. OACONTROL isn't part of the hardware context, so to avoid leaving counters enabled for other applications, we turn them off at the end of the batch too. We also need to start them at BeginPerfMonitor time (unless they've already been started). We stop them when the monitor last ends as well.

* i965: Enumerate Observability Architecture counters on Gen5+.Kenneth Graunke2013-11-212-0/+306
| | | | | | | | | | | | | | | In addition to listing the counter names, we include several "remap" tables. Confusingly, counters are documented with names like "A23", are written to some buffer offset other than 23, and exposed by core Mesa under a counter ID that is different still. The first is inevitable; MI_REPORT_PERF_COUNT writes certain counters to fixed locations in the buffer. The latter could be avoided, but core Mesa uses the "Counters" array index as the ID for a counter. We could do remapping there, but it would just complicate the core Mesa code.

| | | | | | | | | | | | | | | | | | | Without hardware contexts, the pipeline statistics registers are free-running and include data from every 3D application running. In order to find out the contributions of one particular context, we need to take a snapshot at the start and end of each batch. Previously, we emitted the PIPE_CONTROL necessary to capture PS_DEPTH_COUNT when drawing primitives. Special tracking ensured it happened only on the first draw of the batch, rather than on every draw. Moving this to brw_new_batch increases symmetry, since the final snapshot has always been in brw_finish_batch, which is just a few lines below. It should be basically equivalent.

* llvmpipe: calculate more accurate interpolation value at originRoland Scheidegger2013-11-211-6/+82
| | | | | | | | | | | | | | | | | Some rounding errors could crop up when calculating a0. Use a more accurate method (barycentric interpolation essentially) to fix this, though to fix the REAL problem (which is that our interpolation will give very bad results with small triangles far away from the origin when they have steep gradients) this does absolutely nothing (actually makes it worse). (To fix the real problem, either would need to use a vertex corner (or some other point inside the tri) as starting point value instead of fb origin and pass that down to interpolation, or mimic what hw does, use barycentric interpolation (using the coordinates extracted from the rasterizer edge functions) - maybe another time.) Some (silly) tests though really want a high accuracy at fb origin and don't care much about anything else (Just. Don't. Ask.). Reviewed-by: Jose Fonseca <[email protected]>

This adds overhead to _mesa_load_state_parameter, which is uncomfortable, but I'm pretty sure that giant switch statement is super slow already.

| | | | | | | | | | | | | | | | | | | It's not necessary to scale down cubemap texture coords when generating mipmaps: we are doing a 2x minification therefore it's guaranteed that the texture coords will always be at least 1 texel away of the edges. Scaling down can actually be harmful, as it may cause artefacts when generating mipmaps with nearest filtering. Sample points will lie exactly in the middle each 2x2 texels, so the scaling factor was causing different texels to be take on each quadrant of the cube face. This is apparent with a 1x1 checkerboard pattern in the base mipmap level: instead of next mipmap level receiving a constant color throughout the face, it will have different colors for each quadrant of the face. The behaviour for blits is left untouched for now, but the cubemap texture coord scaling hack should be reconsidered eventually. Reviewed-by: Brian Paul <[email protected]>
