* i965: Fix gl_VertexID when there are no other vertex inputs.Paul Berry2012-12-181-3/+3
| | | | | | | | | | | | brw_emit_vertices contains special case logic to handle the case where a vertex shader doesn't read any inputs. This special case logic was incorrectly activating in the case were the only vertex input is gl_VertexID. As a result, if a shader used gl_VertexID but used no other inputs, then all vertices got a gl_VertexID of zero. Fixes oglconform test "ubo-usage advanced.transform_feedback".

* mesa: Fix corner cases of BindBufferBase with transform feedback.Paul Berry2012-12-183-17/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the following behaviours, which are mandated by the GL 4.3 and GLES3 specs. 1. Regarding the GL_TRANSFORM_FEEDBACK_BUFFER_SIZE query: "If the ... size was not specified when the buffer object was bound (e.g. if it was bound with BindBufferBase), ... zero is returned." (GL 4.3 section 6.7.1 "Indexed Buffer Object Limits and Binding Queries"). 2. "BindBufferBase binds the entire buffer, even when the size of the buffer is changed after the binding is established. It is equivalent to calling BindBufferRange with offset zero, while size is determined by the size of the bound buffer at the time the binding is used." (GL 4.3 section 6.1.1 "Binding Buffer Objects to Indexed Targets"). I interpret "at the time the binding is used" to mean "at the time of the call to glBeginTransformFeedback". 3. "Regardless of the size specified with BindBufferRange, or indirectly with BindBufferBase, the GL will never read or write beyond the end of a bound buffer. In some cases this constraint may result in visibly different behavior when a buffer overflow would otherwise result, such as described for transform feedback operations in section 13.2.2." (GL 4.3 section 6.1.1 "Binding Buffer Objects to Indexed Targets"). Item 1 has been part of the spec all the way back to the inception of the EXT_transform_feedback extension. Items 2 and 3 were added in GL 4.2 and GLES 3. Prior to GL 4.2, in place of items 2 and 3, the spec simply said "BindBufferBase is equivalent to calling BindBufferRange with offset zero and size equal to the size of buffer." For transform feedback, Mesa behaved as though this meant "...equal to the size of buffer at the time of the call to BindBufferBase". However, this was problematic because it left it ambiguous what to do if the buffer is shrunk between the call to BindBuffer{Base,Range} and the call to BeginTransformFeedback. Prior to this patch, Mesa's behaviour was to try to write beyond the end of the buffer, likely resulting in memory corruption. In light of this, I'm interpreting the spec change as a clarification, not an intended behavioural change, so I'm making the change apply regardless of API version.

* mesa/gles3: Generate error on draw call if transform feedback would overflow.Paul Berry2012-12-183-1/+80
| | | | | | | | | | | | | | | | | In desktop GL, if a draw call would cause transform feedback buffers to overflow, the draw call should succeed, and the extra primitives should simply not be recorded in the transform feedback buffers. In GLES3, however, if a draw call would cause transform feedback buffers to overflow, the draw call is supposed to produce an INVALID_OPERATION error and no drawing should occur. This patch implements the GLES3-required behaviour. Fixes GLES3 conformance test "transform_feedback_overflow.test".

| | | | | | | | | | | | | | | | | Previously, the i965 driver contained code to compute the maximum number of vertices that could be written without overflowing any transform feedback buffers. This code wasn't driver-specific, and for GLES3 support we're going to need to use it in core mesa. So this patch moves the code into a core mesa function, _mesa_compute_max_transform_feedback_vertices().

This will be needed for GLES3, which requires draw calls to fail if there is not enough space available in transform feedback buffers to accommodate the primitives to be drawn.

* i965: Jump to the end of the next outer conditional block on ENDIFs.Kenneth Graunke2012-12-141-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the Ivybridge PRM, Volume 4, Part 3, section 6.24 (page 172): "The endif instruction is also used to hop out of nested conditionals by jumping to the end of the next outer conditional block when all channels are disabled." Also: "Pseudocode: Evaluate(WrEn); if ( WrEn == 0 ) { // all channels false Jump(IP + JIP); }" First, ENDIF re-enables any channels that were disabled because they didn't match the conditional. If any channels are active, it proceeds to the next instruction (IP + 16). However, if they're all disabled, there's no point in walking through all of the instructions that have no effect---it can jump to the next instruction that might re-enable some channels (an ELSE, ENDIF, or WHILE). Previously, we always set JIP on ENDIF instructions to 2 (which is measured in 8-byte units). This made it do Jump(IP + 16), which just meant it would go to the next instruction even if all channels were off. It turns out that walking over instructions while all the channels are disabled like this is worse than just instruction dispatch overhead: if there are texturing messages, it still costs a couple hundred cycles to not-actually-read from the texture results. This patch finds the next instruction that could re-enable channels and sets JIP accordingly. Reviewed-by: Eric Anholt <[email protected]>
