* i965 gen6+: Use 1-wide null operands for IF instructionsPaul Berry2011-12-201-4/+4
| | | | | | | | | | | | | | The Sandy Bridge PRM, volume 4, part 2, section 5.3.10 ("5.3.10 Register Region Restrictions") contains the following restriction on the execution size and operand width of instructions: "3. ExecSize must be equal to or greater than Width." When emitting an IF instruction in single program flow mode on Gen6+, we use an ExecSize of 1, therefore the Width of each operand must also be 1.

* mesa: Fix off-by-one error in transform feedback size check.Paul Berry2011-12-201-1/+1
| | | | | | | | | | | In _mesa_BindBufferRange(), we need to verify that the offset and size specified by the client do not exceed the size of the underlying buffer. We were accidentally doing this check using ">=" rather than ">", so we were generating a bogus error if the client specified an offset and size that fit exactly in the underlying buffer.

* mesa: Record transform feedback strides/offsets in linker output.Paul Berry2011-12-202-1/+14
| | | | | | | | | | | | | | | | | | | | | | This patch adds two new fields to the gl_transform_feedback_info struct: - BufferStride records the total number of components (per vertex) that transform feedback is being instructed to store in each buffer. - Outputs[i].DstOffset records the offset within the interleaved structure of each transform feedback output. These values are needed by the i965 gen6 and r600g back-ends, so it seems better to have the linker provide them rather than force each back-end to compute them independently. Also, DstOffset helps pave the way for supporting ARB_transform_feedback3, which allows the transform feedback output to contain holes between attributes by specifying gl_SkipComponents{1,2,3,4} as the varying name.

* glx: Send DestroyContext protocol at the correct timesIan Romanick2011-12-196-26/+31
| | | | | | | | | | | | | | | | | | | | | | | Send the DestroyContext protocol immediately when glXDestroyContext is called, and never call it when glXFreeContextEXT is called. In both cases, either destroy the client-side structures or, if the context is current, set xid to None so that the client-side structures will be destroyed later. I believe this restores the behavior of the original SGI code. See src/glx/x11 around commit 5df82c8. The spec doesn't say anything about glXDestroyContext not really destroying imported contexts (it acts like glXFreeContextEXT instead), but that's what the original code did. Note that glXFreeContextEXT on a non-imported context does not destroy it either. Fixes the piglit test glx-free-context. NOTE: This is a candidate for the 7.11 branch.

* glx: Don't create a shared context if the other context isn't the same kindIan Romanick2011-12-193-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each of the DRI, DRI2, and DRISW backends contain code like the following in their create-context routine: if (shareList) { pcp_shared = (struct dri2_context *) shareList; shared = pcp_shared->driContext; } This assumes that the glx_context *shareList is actually the correct derived type. However, if shareList was created as an indirect-rendering context, it will not be the expected type. As a result, shared will contain garbage. This garbage will be passed to the driver, and the driver will probably segfault. This can be observed with the following GLX code: ctx0 = glXCreateContext(dpy, visinfo, NULL, False); ctx1 = glXCreateContext(dpy, visinfo, ctx0, True); Create-context is the only case where this occurs. All other cases where a context is passed to the backend, it is the 'this' pointer (i.e., we got to the backend by call something from ctx->vtable). To work around this, check that the shareList->vtable->destroy method is the same as the destroy method of the expected type. We could also check that shareList->vtable matches the vtable or by adding a "tag" to glx_context to identify the derived type. NOTE: This is a candidate for the 7.11 branch.
