* mesa: Ensure that transform feedback refers to the correct program.Paul Berry2014-01-231-13/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | Previous to this patch, the _mesa_{Begin,Resume}TransformFeedback functions were using ctx->Shader.CurrentProgram[MESA_SHADER_VERTEX] to find the program that would be the source of transform feedback data. This isn't correct--if there's a geometry shader present it should be ctx->Shader.CurrentProgram[MESA_SHADER_GEOMETRY]. (These might be different if separate shader objects are in use). This patch creates a function get_xfb_source(), which figures out the correct program to use based on GL state, and updates _mesa_{Begin,Resume}TransformFeedback to call it. get_xfb_source() is written in terms of the gl_shader_stage enum, so it should not need modification when we add tessellation shaders in the future. It also creates a new driver flag, NewTransformFeedbackProg, which is flagged whenever this program changes. To reduce future confusion, this patch also rewords some comments and error message text to avoid referring to vertex shaders.

If any active objects refer to a program, LinkProgram must reject the request to relink.

* mesa: Fix corner cases of BindBufferBase with transform feedback.Paul Berry2012-12-181-15/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Berry2012-12-181-1/+18
| | | | | | | | | | | | | | | | | 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.
