* xlib: handle _mesa_initialize_visual()'s return valueBrian Paul2012-12-311-9/+12
| | | | | | | | | If the call fails, we should return NULL from XMesaCreateVisual(). This was found when Waffle tried to create a visual with depth/stencil bits = -1. That's an illegal value for glXChooseFBConfig() and we should return NULL in that situation. Note: This is a candidate for the stable branches.
* i965: Fail to blit rather than assert on invalid pitch requirements.Kenneth Graunke2012-12-291-2/+2
| | | | | | | | | | | | | | | | | | | Dungeon Defenders hits TexImage()'s try_pbo_upload() path where image->Width == 2, which doesn't meet intelEmitCopyBlit's requirement that the pitch needs to be a multiple of 4. Since intelEmitCopyBlit can already fail for a myriad of other reasons, and it's not clear that other callers are immune to this failure mode, simply make it return false rather than assert. Fixes Dungeon Defenders on i965/Ivybridge. Now playable (aside from having to work around the EXT_bindable_uniform issue). NOTE: This is probably a candidate for the 9.0 branch.

* mesa: Allow glReadBuffer(GL_NONE) for winsys framebuffers.Paul Berry2012-12-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | Previously, Mesa code assumed that glReadBuffer(GL_NONE) was only valid for user-created framebuffer objects. However, the spec is quite clear that is should also be valid for the default framebuffer. From section 18.2.1 ("Obtaining Pixels from the Framebuffer") of the GL 4.3 spec: "When READ_FRAMEBUFFER_BINDING is zero, i.e. the default framebuffer, src must be one of the values listed in table 17.4, including NONE." Similar language exists in the GLES 3.0 spec, and in desktop GL all the way back to ARB_framebuffer_object. Partially fixes GLES3 conformance test "CoverageES30.test".

| | | | | | | | | | | | | | | | | | ARB/EXT_timer_query's definition of GL_TIME_ELAPSED match precisely the subtraction of two GL_TIMESTAMP queries. And for a lot of drivers, that's precisely how they have to implement internally -- by emitting two hardware timestamp queries. So, to simplify driver implementation, simply allow doing so in the state tracker. Eventually if no driver implements PIPE_QUERY_TIME_ELAPSED then we could retire it.

| | | | | | | | | | | | 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.

* 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.
