* meta: Push into desktop GL mode when doing meta operations.Eric Anholt2014-02-181-0/+3
| | | | | | | | This lets us simplify our shaders, and rely on GLES-prohibited functionality (like ARB_texture_multisample) when writing these driver-internal functions. Reviewed-by: Kenneth Graunke <[email protected]>
* meta: De-static some of meta's functions.Eric Anholt2014-02-121-0/+56
| | | | | | | | | | | I want split some meta.c code off to a separate file, so these functions can't be static any more. v2: Rebase on idr's changes, also expose setup_blit_shader, blit_shader_table_cleanup, setup_vertex_objects, setup_ff_tnl_for_blit.

| | | | | | | | | I'd like to split some of our code to separate files, since 4k lines and growing is pretty unreasonable for all these separate operations. v2: Rebase on idr's changes. Reviewed-by: Kenneth Graunke <[email protected]> (v1)
* mesa: Hide weirdness of 1D_ARRAY textures from Driver.CopyTexSubImage().Eric Anholt2013-06-171-1/+1
| | | | | | | | | | | | | | | | | Intel had brokenness here, and I'd like to continue moving Mesa toward hiding 1D_ARRAY's ridiculousness inside of the core, like we did with MapTextureImage. Fixes copyteximage 1D_ARRAY on intel. There's still an impedance mismatch in meta when falling back to read and texsubimage, since texsubimage expects coordinates into 1D_ARRAY as (width, slice, 0) instead of (width, 0, slice). v2: Fix offset of scanline reads from the source. (Thanks Brian!), replace dd.h comment with Paul's text and replace early exit with an assert.

* meta: Allow meta operations to pause/resume an active occlusion queryCarl Worth2013-01-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This allows for avoiding the occlusion query erroneously accumulating results during the meta operation. This functionality is made conditional on a new MESA_META_OCCLUSION_QUERY bit so that meta-operations which should generate fragments can continue to get the current behavior. The implementation of glClear is specifically augmented to request the flag since glClear is specified to not generate fragments. This fixes the following es3conform tests: occlusion_query_draw_occluded.test occlusion_query_clear occlusion_query_custom_framebuffer occlusion_query_stencil_test occlusion_query_discarded_fragments As well as the following piglit test: occlusion_query_meta_no_fragments Reviewed-by: Ian Romanick <[email protected]>
* meta: Properly save/restore GL_FRAMEBUFFER_SRGB in Meta.Paul Berry2012-09-251-0/+1
| | | | | | | | | | | | | | | | | | | Previously, meta logic was saving and restoring the value of GL_FRAMEBUFFER_SRGB in an ad-hoc fashion. As a result, it was not properly disabled and/or restored for some meta operations. This patch causes GL_FRAMEBUFFER_SRGB to be saved/restored in the conventional way of meta-ops (using _mesa_meta_begin() and _mesa_meta_end()). It is now reliably saved/restored for _mesa_meta_BlitFramebuffer, _mesa_meta_GenerateMipmap, and decompress_texture_image, and preserved for all other meta ops. Fixes piglit tests "ARB_framebuffer_sRGB/blit renderbuffer {linear_to_srgb,srgb} scaled {disabled,enabled}".

* msaa: Make meta-ops save and restore state of GL_MULTISAMPLE.Paul Berry2012-07-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | The meta-ops _mesa_meta_Clear() and _mesa_meta_glsl_Clear() need to ignore the state of GL_SAMPLE_ALPHA_TO_COVERAGE, GL_SAMPLE_ALPHA_TO_ONE, GL_SAMPLE_COVERAGE, GL_SAMPLE_COVERAGE_VALUE, and GL_SAMPLE_COVERAGE_INVERT when clearing multisampled buffers. The easiest way to accomplish this is to disable GL_MULTISAMPLE during the clear meta-ops. Note: this patch also causes GL_MULTISAMPLE to be disabled during _mesa_meta_GenerateMipmap() and _mesa_meta_GetTexImage() (since those two meta-ops use MESA_META_ALL). Arguably this isn't strictly necessary, since those meta-ops use their own non-MSAA fbo's, but it shouldn't do any harm.

Implement glClear() in terms of quad rendering, implement glBlitFramebuffer() in terms of glCopyTexImage2D + textured quad, etc. There have been several places in the drivers where we've implemented meta rendering similar to this. This is an effort to do it in a more portable and more efficient form. The _mesa_meta_begin/end() functions act like glPush/PopAttrib() but are lighter-weight. Plus, _mesa_meta_begin() resets GL state back to default values (texturing off, identity vertex transform, etc) so the meta drawing functions don't have to worry about it. For now only _mesa_mesa_blit_framebuffer() and _mesa_meta_clear() are implemented. glDrawPixels() and glCopyPixels() would be the next candidates.
