2009-05-08i965: don't use GRF regs 126,127 for WM programsBrian Paul
They seem to be used for something else and using them for shader temps seems to lead to GPU lock-ups. Call _mesa_warning() when we run out of temps. Also, clean up some debug code.

2009-05-06i965: Remove bad constant buffer constant-reg-already-loaded optimization.Eric Anholt
Thanks to branching, the state of c->current_const[i].index at the point of emitting constant loads for this instruction may not match the actual constant currently loaded in the reg at runtime. Fixes a regression in my GLSL program for idr's class since b58b3a786aa38dcc9d72144c2cc691151e46e3d5.
2009-05-06intel: Unmap buffers if needed at DeleteBuffer time.Eric Anholt
This fixes a crash in glean's pbo test, which tripped over the assert when a context was destroyed while a buffer was still mapped (Mesa doesn't call UnmapBuffer in that case). Regression in c6bde8873fbda6d8467600b7491d8543c75b0509
2009-05-06i965: Remove the forced lack of caching for renderbuffer surface state.Eric Anholt
This snuck in with the multi-draw-buffers commit, and is a major penalty to performance. It doesn't appear to be required, as the only dependency the surface BO has is on the state key (and if there's some other dependency, it should just be in the key). This brings openarena performance up to almost 2% faster than Mesa 7.4.
2009-05-06i965: Remove _NEW_PROGRAM from brw_wm_surfaces setup dependencies.Eric Anholt
This was a leftover from the brw_wm_constant_buffer change.
2009-05-06i965: Split WM constant buffer update from other WM surfaces.Eric Anholt
This can avoid re-uploading constant data when it isn't necessary, and is a step towards not updating other surfaces just because constants change. It also brings the upload of the constant buffer next to the creation. This brings openarena performance up another 4%, to 91% of the Mesa 7.4 branch.
2009-05-06i965: Disentangle VS constant surface state from WM surface state.Eric Anholt
Also, only create VS surface state if there's a VS constant buffer to be uploaded, and set the contents of the buffer at the same time as creation.
2009-05-06i965: Don't create constant buffers if they won't be used.Eric Anholt
Really, the creation and upload of constants should be in the same place, since they should only happen together, and a state flag should be triggered by them so that we don't thrash state around so much for just updating constants. But this still recovers openarena performance by another 19%, leaving us 16% behind Mesa 7.4 branch.
2009-05-01mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXELBrian Paul
Since GL_READ_BUFFER is historically part of the gl_pixel_attrib group it made sense to signal changes with _NEW_PIXEL. But now with FBOs it's also part of the framebuffer state. Now _NEW_PIXEL strictly indicates pixels transfer state changes. This change avoids framebuffer state validation when any random bit of pixel-transfer state is set. DRI drivers updated too: don't check _NEW_COLOR when updating framebuffer state. I think that was just copied from the Xlib driver because we care about dither enable/disable state there.
2009-05-01Test either GL_FRONT_LEFT or GL_FRONT for front-buffer renderingIan Romanick
For non-stereo visuals, which is all we support, we treat GL_FRONT_LEFT as GL_FRONT. However, they are technically different, and they have different enum values. Test for either one to determine if we're in front-buffer rendering mode. This fix was suggested by Pierre Willenbrock. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>

2009-04-30r300: Increase reference count of texture objects referenced by current state.Michel Dänzer
Fixes a use-after-free reported in http://bugs.freedesktop.org/show_bug.cgi?id=20539, so this possibly fixes that bug. It has been confirmed to fix http://bugs.freedesktop.org/show_bug.cgi?id=17895 .

2009-04-27i965: only upload constant buffer data when we actually need the const bufferBrian Paul
Make the use_const_buffer field per-program and only call the code which updates the constant buffer's data if the flag is set. This should undo the perf regression from 20f3497e4b6756e330f7b3f54e8acaa1d6c92052 (cherry picked from master, commit dc9705d12d162ba6d087eb762e315de9f97bc456)

2009-04-24i965: rework GLSL/WM register allocationBrian Paul
Use a bitvector of used/free flags. If we run out of temps, examine the live intervals of the temp regs in the program and free those which are no longer alive. Also, enable the new WM const buffer code.

2009-04-24intel: Initialize region ptr to prevent assertion in intel_region_referenceIan Romanick
2009-04-24intel / DRI2: When available, use DRI2GetBuffersWithFormatIan Romanick
This interface gives the driver two important features. First, it can allocate the (fake) front-buffer only when needed. Second, it can tell the buffer allocator the format of buffers being allocated. This enables support for back-buffer and depth-buffer with different bits per pixel.

need to clamp point size to user set min/max values, even for constant point size. Fixes glean pointAtten test.
2009-04-23i965: revert part of commit 4f4907d69f9020ce17aef21b6431d2dd65e01982Brian Paul
The drm_intel_gem_bo_map_gtt() call that replaced dri_bo_map() is producing errors like: intel_bufmgr_gem.c:689: Error preparing buffer map 39 (vp_const_buffer): Invalid argument . and returning NULL, causing a segfault in the memcpy(). Just reverting until we can get to the root issue...

2009-04-23intel: Take advantage of GL_READ_ONLY_ARB to map to GEM bo_map write flag.Eric Anholt
This is a CPU win in general, but in particular reduces the pain of Mesa's calculation of min/max indices in DrawElements (wtf?).
2009-04-22i965: disable debug printfBrian Paul
2009-04-22i965: enable VS constant buffersBrian Paul
In the VS constants can now be handled in two different ways: 1. If there's room in the GRF, put constants there. They're preloaded from the CURBE prior to VS execution. This is the historical approach. The problem is the GRF may not have room for all the shader's constants and temps and misc registers. Hence... 2. Use a separate constant buffer which is read from using a READ message. This allows a very large number of constants and frees up GRF regs for shader temporaries. This is the new approach. May be a little slower than 1. 1 vs. 2 is chosen according to how many constants and temps the shader needs.

2009-04-22i965: actually use the new, second surface state cacheBrian Paul
2009-04-22i965: checkpoint commit: use two state caches instead of oneBrian Paul
The new, second cache will only be used for surface-related items. Since we can create many surfaces the original, single cache could get filled quickly. When we cleared it, we had to regenerate shaders, etc. With two caches, we can avoid doing that.
2009-04-22i965: remove unused state atom entriesBrian Paul
2009-04-22intel: fix max anisotropy supportedRoland Scheidegger
i915 actually supports up to 4 (according to header file - not tested), i965 up to 16 (code already handled this but slightly broken), so don't use 2 for all chips, even though angular dependency is very high.
2009-04-22i965: the brw_constant_buffer state atom is no longer dynamicBrian Paul
No more dynamic atoms so we can simplify the state validation code a little.

2009-04-22i965: use _NEW_PROGRAM_CONSTANTS and always create new const buffersBrian Paul
When program constants change we create a new VS constant buffer instead of re-using the old one. This allows us to have several const buffers in flight with vertex rendering.
