* main: Fix deprecation of glLineWidth()Paul Berry2013-08-091-1/+2
| | | | | | | | | | | | | | | | | | | | | From section E.1 (Profiles and Deprecated Features of OpenGL 3.0) of the OpenGL 3.0 spec: "LineWidth is not deprecated, but values greater than 1.0 will generate an INVALID VALUE error" From context it is clear that values greater than 1.0 should only generate an INVALID VALUE error in a forward-compatible context. The code was correctly quoting this spec text, but it was disallowing all line widths in forward-compatible contexts, instead of just widths greater than 1.0. This patch introduces the correct check, so that setting a line width of 1.0 or less is permitted. Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* i965: Initialize the intel_context::bufmgr pointer earlier.Kenneth Graunke2013-08-061-2/+1
| | | | | | | | | | | | | | | | | This prevents a crash in a future patch. _mesa_initialize_context() creates a default transform feedback object by calling the NewTransformFeedbackObject() driver hook. Eventually, we'll want to subclass that and allocate a buffer object. This means passing brw->bufmgr to drm_intel_alloc_bo(), and crashing if it isn't initialized yet. The buffer manager is actually already initialized; we just hadn't copied the pointer from intel_screen to intel_context quite early enough.

* i965: Tidy preprocessor macros for SO_PRIM_STORAGE_NEEDED registers.Kenneth Graunke2013-08-061-5/+2
| | | | | | | | | | | | | | | Gen7+ supports four transform feedback streams. Using a function-like macro makes it easy to access them by stream number or loop over them. "GEN7_" prefixes are more common than "_IVB" suffixes, so use that. Gen6 only supports a single stream, so the single #define should be fine. However, SO_NUM_PRIM_STORAGE_NEEDED was a poor name. For one, the word "NUM" doesn't appear in the actual name of the register. It's also confusingly generic, as it doesn't exist on Gen7+. Add a "GEN6_" prefix for clarity.

| | | | | | | | | | | | | | | | | | | | | Previously we would always find the 2D sub-surface of interest, and then program the surface to this location. Now we always program the 3DSTATE_DEPTH_BUFFER at the start of the surface. To select the lod/slice, we utilize the lod & minimum array element fields. As part of this change, we must revert 1f112ccf: Revert "i965/gen7: Align all depth miplevels to 8 in the X direction." We also must disable brw_workaround_depthstencil_alignment for gen >= 7.

* gen7 fbo: make unmatched depth/stencil configs return unsupportedJordan Justen2013-08-041-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | For gen >= 7, we will use the lod/minimum-array-element fields to support layered rendering. This means that we must restrict the depth & stencil attachments to match in various more retrictive ways. (Now the width, height, depth, LOD and layer must match) The reason width, height, and depth must match is that the hardware has a single set of width, height, and depth settings (in 3DSTATE_DEPTH_BUFFER) that affect both the depth and stencil buffers. Since these controls determine the miptree layout, they need to be set correctly in order for lod and minimum-array-element to work properly. So the only way rendering can work is if the width, height, and depth match. In the future, if this restriction proves to be a problem (say because some crucial client application relies on rendering to different levels/layers of stencil and depth buffers), then we can always work around the restriction by copying depth and/or stencil data to a temporary buffer prior to rendering (much in the same way that brw_workaround_depthstencil_alignment() does today for gen < 7), but hopefully that won't be necessary.

| | | | | | | | | | | | | | | | | | | | | | Previously, we assumed that the only way Mesa would expose geometry shader support was via the ARB_geometry_shader4 extension. But this extension has some extra complications over GL 3.2 (interactions with compatibility-only features, and link-time initialization of the constant gl_VerticesIn). So we want to allow for the possibility of supporting GL 3.2 (with GLSL 1.50 style geometry shaders) even if ctx->Extensions.ARB_geometry_shader4 is false. This patch adds a new function, _mesa_has_geometry_shaders(), which returns true if either ARB_geometry_shader4 is supported or the GL version is at least 3.2 desktop. Since compute_version() only enables GL 3.2 functionality when GLSL 1.50 support is present, a sufficient way for a back-end to advertise geometry shader support is to set ctx->Const.GLSLVersion >= 150. v2: Remove unnecessary ctx->Const.GeometryShaders150 constant.
