* mesa: if MESA_DEBUG=context, create a debug contextBrian Paul2016-11-161-0/+2
| | | | | | | | | | | | | | | | | | | A number of drivers report useful debug/perf information accessible through GL_ARB_debug_output and with debug contexts (i.e. setting the GLX_CONTEXT_DEBUG_BIT_ARB flag). But few applications actually use the GL_ARB_debug_output extension. This change lets one set the MESA_DEBUG env var to "context" to force-set a debug context and report debug/perf messages to stderr (or whatever file MESA_LOG_FILE is set to). This is a useful debugging tool. The small change in st_api_create_context() is needed so that st_update_debug_callback() gets called to hook up the driver debug callbacks when ST_CONTEXT_FLAG_DEBUG was not set, but MESA_DEBUG=context. v2: use %.*s format string instead of allocating temporary buffer.

* st/mesa: initialize members of glsl_to_tgsi_instruction in emit_asm()Brian Paul2016-11-051-0/+4
| | | | | | | | | | | | | | This fixes random crashes with MSVC release builds. It seems the members are implicitly initialized to zero with gcc, but not MSVC. In particular, the tex_offset_num_offset field was non-zero causing a loop over the NULL tex_offsets array to crash. Zero-init those fields and a few others to be safe. The regression began with acc23b04cfd64e "ralloc: remove memset from ralloc_size". Reviewed-by: Marek Olšák <[email protected]>
* st/mesa: fix the layer of VDPAU surface samplersNicolai Hähnle2016-11-043-17/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A (latent) bug in VDPAU interop was exposed by commit e5cc84dd43be066c1dd418e32f5ad258e31a150a. Before that commit, the st_vdpau code created samplers with first_layer == last_layer == 1 that the general texture handling code would immediately delete and re-create, because the layer does not match the information in the GL texture object. This was correct behavior at least in the DMABUF case, because the imported resource is supposed to have the correct offset already applied. In the non-DMABUF case, this was just plain wrong but apparently nobody noticed. After that commit, the state tracker assumes that an existing sampler is correct at all times. Existing samplers are supposed to be deleted when they may become invalid, and they will be created on-demand. This meant that the sampler with first_layer == last_layer == 1 stuck around, leading to rendering artefacts (on radeonsi), command stream failures (on r600), and assertions (in debug builds everywhere). This patch fixes the problem by simply not creating a sampler at all in st_vdpau_map_surface. We rely on the generic texture code to do the right thing, adding the layer_override to make the non-DMABUF case work. v2: add the layer_override Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98512 Cc: 13.0 <[email protected]> Cc: Christian König <[email protected]> Cc: Ilia Mirkin <[email protected]> Reviewed-by: Marek Olšák <[email protected]> (v1) Reviewed-by: Christian König <[email protected]>

* st/mesa/r200/i915/i965: use rzalloc() to create gl_programTimothy Arceri2016-11-031-6/+12
| | | | | | | | | | | | | | | | | This allows us to use ralloc_parent() to see which data structure owns shader_info which allows us to fix a regression in nir_sweep(). This will also allow us to move some fields from gl_linked_shader to gl_program, which will allow us to do some clean-ups like storing gl_program directly in the CurrentProgram array in gl_pipeline_object enabling some small validation optimisations at draw time. Also it is error prone to depend on the gl_linked_shader for programs in current use because a failed linking attempt will free infomation about the current program. In i965 we could be trying to recompile a shader variant but may have lost some required fields. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | The term "client array" is a legacy thing dating back to the pre-VBO era when _all_ vertex arrays lived in client memory. Nowadays, it only contains vertex array state which is derived from gl_array_attributes and gl_vertex_buffer_binding. It's used by the VBO module and some drivers.
