* i965: Share the register file enum between the two backends.Eric Anholt2013-05-027-34/+24
| | | | | | | | | | I need this so I can look at vec4 and fs registers' files from the same .cpp file without namespaces. As far as I can tell we never rely on the particular numerical values of the files, though I thought it sounded like a good idea when doing the VS (it turns out having 0 be BAD_FILE is nicer).

* i965: Fix SNB GPU hangs when a blorp batch is the first thing to execute.Eric Anholt2013-05-021-0/+35
| | | | | | | | | | | | | | The GPU apparently goes looking for constants even though there are no shader stages enabled, and gets stuck because we haven't told it there are no constants to collect. If any other user of the 3D pipeline had run (even the Render accel of the X server!) since power on, then the in-GPU constant buffers would have been set up with some contents we didn't use, and we would succeed.

* mesa: simplify dispatch for glDraw* functionsBrian Paul2013-05-028-401/+17
| | | | | | | | | | | | Remove all the glDraw* functions from the GLvertexformat structure. The point of that dispatch struct is to handle all the functions which dispatch differently depending on whether we're inside glBegin/End. glDraw* are never allowed inside glBegin/End so we can remove those entries. This simplifies the code paths and gets rid of quite a bit of code. Reviewed-by: Jose Fonseca <[email protected]>

* mesa: change _mesa_inside_dlist_begin_end() to handle PRIM_UNKNOWNBrian Paul2013-05-022-5/+3
| | | | | | | | | | | | If the currently compiled primitive state is PRIM_UNKNOWN we should not return true from _mesa_inside_dlist_begin_end(). This lets us simplify the calls to that function. Note, the call to _mesa_inside_dlist_begin_end() in vbo_save_EndList() should have probably been checking for PRIM_UNKNOWN too, but it wasn't. So there's no code change change.

| | | | | | | | | | | | | | | | The _save_OBE_DrawArrays/Elements/RangeElements() functions are called when building a display list and we know we're outside glBegin/End. We shouldn't call the normal _mesa_validate_DrawArrays/Elements() functions here because those functions only work properly in immediate mode or during dlist execution. At dlist compile time, we can't call _mesa_update_state(), etc. and examine the current state since it won't apply when the list is executed later.

* mesa: fix save_ShadeModel() logic and add new commentsBrian Paul2013-05-021-4/+5
| | | | | | | | | | | | | | | | This removes the test for _mesa_inside_dlist_begin_end(). If ctx->Driver.CurrentSavePrimitive==PRIM_UNKNOWN (the initial value), _mesa_inside_dlist_begin_end() will, confusingly, return TRUE. So we didn't set the ctx->ListState.Current.ShadeModel value and it remained in its indeterminate state. This didn't effect correctness, but it defeated the intended optimization of dropping redundant glShadeModel() state changes in order to coalesce sequences of drawing commands.

* i965: Lower textureGrad() for samplerCubeShadow.Kenneth Graunke2013-05-013-6/+27
| | | | | | | | | | | | | | | | | | | | | | | According to the Ivybridge PRM, Volume 4 Part 1, page 130, in the section for the sample_d message: "The r coordinate contains the faceid, and the r gradients are ignored by hardware." This doesn't match GLSL, which provides gradients for all of the coordinates. So we would need to do some math to compute the face ID before using sample_d. We currently don't have any code to do that. However, we do have a lowering pass that converts textureGrad to textureLod, which solves this problem. Since textureGrad on three components is sufficiently obscure, it's not a performance path. For now, only handle samplerCubeShadow; we need tests for samplerCube and samplerCubeArray. Fixes es3conform's shadow_comparison_frag test on Haswell. NOTE: This is a candidate for stable branches. Signed-off-by: Kenneth Graunke <[email protected]>

* i965: Implement color clears using a simple shader in blorp.Eric Anholt2013-04-308-14/+344
| | | | | | | | | | | | | | | | | | | | | | | The upside is less CPU overhead in fiddling with GL error handling, the ability to use the constant color write message in most cases, and no GLSL clear shaders appearing in MESA_GLSL=dump output. The downside is more batch flushing and a total recompute of GL state at the end of blorp. However, if we're ever going to use the fast color clear feature of CMS surfaces, we'll need this anyway since it requires very special state setup. This increases the fail rate of some the GLES3conform ARB_sync tests, because of the initial flush at the start of blorp. The tests already intermittently failed (because it's just a bad testing procedure), and we can return it to its previous fail rate by fixing the initial flush.

More importantly, once color glClear()s are done through blorp in the next commit, this reduces regression in GLES3 conformance tests that rely on queueing up many glClear()s and having the GPU report being still busy in an ARB_sync query after that.
