* svga: print warning for unsupported indirect dest reg indexingBrian Paul2013-11-151-0/+4
| | | | | | | | | For DX9-level shaders, there's only limited support for indirect indexing of registers (with the loop counter register, not the general address register.) Reviewed-by: José Fonseca <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
* svga: mark dest image as defined in svga_surface_copy()Brian Paul2013-11-151-0/+2
| | | | | | | | | | | | After we blit/copy to a dest texture image we need to mark it as being defined. This fixes broken mipmap generation for quite a few texture formats. Mipgen involves making texture views and svga_texture_view_surface() skips texture images that are undefined.

* svga: do primitive trimming in translate_indices()Brian Paul2013-11-151-3/+12
| | | | | | | | | | | | | | The index translation code expects the number of indexes to be consistent with the primitive type (ex: a multiple of 3 for PIPE_PRIM_TRIANGLES). If it's not, we can write out of bounds in the destination buffer. Fixes failed assertions in the pipebuffer debug code found with Piglit primitive-restart-draw-mode test.

* svga: always return 4 for PIPE_MAX_COLOR_BUFSBrian Paul2013-11-071-5/+4

* svga: return true for the PIPE_CAP_SM3 queryBrian Paul2013-11-071-1/+3
| | | | | | | | | | This just tells the state tracker to turn on the GL_ARB_shader_texture_lod extension. This simply allows the GLSL compiler to emit TXL and TXD instructions for both vertex and fragment shaders. We already support these opcodes in the svga driver. Though, the shadow2DGrad() Piglit tests are failing. Reviewed-by: José Fonseca <[email protected]>
* draw,llvmpipe,util: add depth bias calculation for arb_depth_buffer_floatMatthew McClure2013-11-071-2/+8
| | | | | | | | | | | | | | | With this patch, the llvmpipe and draw modules will calculate the depth bias according to floating point depth buffer semantics described in the arb_depth_buffer_float specification, when the driver has a z buffer bound with a format type of UTIL_FORMAT_TYPE_FLOAT. By default, the driver will use the existing UNORM calculation for depth bias. A new function, draw_set_zs_format, was added to calculate the Minimum Resolvable Depth value and floating point depth sense for the draw module.

* draw: inject frontface info into wireframe outputsZack Rusin2013-08-021-0/+1
| | | | | | | | | | | | | | Draw module can decompose primitives into wireframe models, which is a fancy word for 'lines', unfortunately that decomposition means that we weren't able to preserve the original front-face info which could be derived from the original primitives (lines don't have a 'face'). To fix it allow draw module to inject a fake face semantic into outputs from which the backends can figure out the original frontfacing info of the primitives.

* tgsi: rename the TGSI fragment kill opcodesBrian Paul2013-07-121-9/+9
| | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional kill (if any src component < 0). The later was unconditional kill. At one time KILP was supposed to work with NV-style condition codes/predicates but we never had that in TGSI. This patch renames both opcodes: TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0) TGSI_OPCODE_KILP -> KILL (unconditional kill) Note: I didn't just transpose the opcode names to help ensure that I didn't miss updating any code anywhere. I believe I've updated all the relevant code and comments but I'm not 100% sure that some drivers had this right in the first place. For example, the radeon driver might have llvm.AMDGPU.kill and llvm.AMDGPU.kilp mixed up. Driver authors should review their code. Reviewed-by: Jose Fonseca <[email protected]>

* gallium: add condition parameter to render_conditionRoland Scheidegger2013-06-181-1/+1
| | | | | | | | | | | | | For conditional rendering this makes it possible to skip rendering if either the predicate is true or false, as supported by d3d10 (in fact previously it was sort of implied skip rendering if predicate is false for occlusion predicate, and true for so_overflow predicate). There's no cap bit for this as presumably all drivers could do it trivially (but this patch does not implement it for the drivers using true hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL functionality).

| | | | | | | | | | | | Pass in the size of the index buffer, when available, and use it to handle out of bounds conditions. The behavior in the case of an overflow needs to be the same as with other overflows in the vertex processing pipeline meaning that a vertex should still be generated but all attributes in it set to zero.

| | | | | | | | | | | | | | We would crash when stride was bigger than the size of the buffer. The correct behavior is to just fetch zero's in this case. Unfortunatly with user_buffer's there's no way to validate the size because currently we're just not getting it. Adjust the draw interface to pass the size along the mapped buffer, which works perfectly for buffer backed vertex_buffers and, in future, it will allow us to plumb user_buffer sizes through the same interface.
