* mesa: Don't leak shared state when context initialization failsIan Romanick2013-04-121-0/+1
| | | | | | | | | | | | | | | | | Back up at line 1017 (not shown in patch), we add a reference to the shared state. Several places after that may divert to the error handler, but, as far as I can tell, nothing ever unreferences the shared state. Fixes issue identified by Klocwork analysis: Resource acquired to 'shared->TexMutex' at line 1012 may be lost here. Also there is one similar error on line 1087.

| | | | | | | | | | | | Since the vec4_visitor and vec4_generator classes are going to be re-used for geometry shaders, we can't enable their debug functionality based on (INTEL_DEBUG & DEBUG_VS) anymore. Instead, add a debug_flag boolean to these two classes, so that when they're instantiated the caller can specify whether debug dumps are needed.

* i965/vs: Generalize computation of array strides in preparation for GS.Paul Berry2013-04-112-4/+16
| | | | | | | | | | | | | | | | | | | Geometry shader inputs are arrays, but they use an unusual array layout: instead of all array elements for a given geometry shader input being stored consecutively, all geometry shader inputs are interleaved into one giant array. As a result, the array stride we use to access geometry shader inputs must be equal to the size of the input VUE, rather than the size of the array element. This patch introduces a new virtual function, vec4_visitor::compute_array_stride(), which will allow geometry shader compilation to specialize the computation of array stride to account for the unusual layout of geometry shader input arrays. It also renames the local variable that the ir_dereference_array visitor uses to store the stride, to avoid confusion.

| | | | | | | | | | | | | | | | | | | | This patch introduces a new function, vec4_visitor::emit_vertex(), which contains the code for emitting vertices that will need to be common between the vertex and geometry shaders. Geometry shaders will need to use a different message header, and a different opcode, for their URB writes, so we introduce virtual functions emit_urb_write_header() and emit_urb_write_opcode() to take care of the GS-specific behaviours. Also, since vertex emission happens at the end of the VS, but in the middle of the GS, we need to be sure to only call emit_shader_time_end() during VS vertex emission. We accomplish this by moving the call to emit_shader_time_end() into the VS implementation of emit_urb_write_opcode().

Having brw_vs_compile point to brw_vs_prog_data makes it difficult to do this cleanly. Fortunately most of the functions that use brw_vs_compile (those in the vec4_visitor class) already have access to brw_vs_prog_data through a separate pointer (vec4_visitor::prog_data). So all we have to do is use that pointer consistently, and plumb prog_data through the few remaining functions that need access to it.

No behavioral change. This prepares for selectively enabling hiz on individual miptree slices for Haswell. This refactoring had several side effects. 1. To prevent new warnings about discarding the const qualifier, I removed 'const' from some variable declarations in intel_validate_framebuffer(). The alternative was to add const qualifiers to multiple function signatures in the intel_renderbuffer_has_hiz call graph. Since the dominant convention in the Intel code is to not qualify function parameters as const, I chose to remove rather than add const qualifiers. 2. I changed the signature of brw_emit_depth_stencil_hiz() by replacing `struct intel_mipmap_tree *hiz_mt` with `bool hiz`. The function used hiz_mt mostly as a boolean indicator of the presence of hiz, so the signature change is consistent with the patch's goal.

| | | | | | | | | | | | | | | | | | | | brw_draw.c contains a trim() function which modifies the vertex count for quads and quad strips in order to discard dangling vertices. In principle this shouldn't be necessary, since hardware since Gen4 is capable of discarding dangling vertices by itself. However, it's necessary because as a hack to speed up rendering on Gen 4-5, we sometimes convert quads to trifans and quad strips to tristrips. The trim() function isn't necessary on Gen6 and up. This patch documents why and when the trim() function is necessary, and avoids calling it when it's not needed. This will avoid creating problems when we enable hardware support for primitive restart of quads and quad strips on Haswell.
