* mesa: Disable certain error checks when transform feedback is pausedPaul Berry2011-12-231-1/+2
| | | | | | | | | | When transform feedback is paused, it is legal to change programs or to perform drawing operations using a drawing mode that doesn't match the transform feedback mode.

* mesa: Ensure that Paused is reset to false on EndTransformFeedback.Paul Berry2011-12-231-0/+1
| | | | | | | | | | | | If a client calls BeginTransformFeedback(), then PauseTransformFeedback(), then EndTransformFeedback(), we need to make sure that the transform feedback object is not left in a "paused" state, otherwise the next call to BeginTransformFeedback() will leave transform feedback paused.

* mesa: Remove unnecessary FLUSH_VERTICES in bind_buffer_rangePaul Berry2011-12-201-1/+5
| | | | | | | | | | It isn't necessary to call FLUSH_VERTICES from bind_buffer_range, because transform feedback buffers are not allowed to be changed when transform feedback is active. Thanks to Marek Olšák for pointing out this bug. Reviewed-by: Marek Olšák <[email protected]>
* 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: implement DrawTransformFeedback from ARB_transform_feedback2Marek Olšák2011-12-151-55/+6
| | | | | | | | | | | | | | It's like DrawArrays, but the count is taken from a transform feedback object. This removes DrawTransformFeedback from dd_function_table and adds the same function to GLvertexformat (with the function parameters matching GL). The vbo_draw_func callback has a new parameter "struct gl_transform_feedback_object *tfb_vertcount". The rest of the code just validates states and forwards the transform feedback object into vbo_draw_func.
* mesa: Track changes to transform feedback state.Paul Berry2011-12-071-1/+8
| | | | | | | | | | | This patch adds a new bit to the ctx->NewState bitfield, _NEW_TRANSFORM_FEEDBACK, to track state changes that affect ctx->TransformFeedback. This bit can be used by driver back-ends to avoid expensive recomputations when transform feedback state has not been modified.

* mesa: Fix many printf-like warnings.Eric Anholt2010-09-011-1/+2
| | | | | | | | Most of these are just typecasting to long to match the arg type. I don't really care too much about getting a GLsizei or whatever appropriate type in. However, there were a number of real bugs, like missing arguments or passing floats to integer format specifiers. My favorite: printflike("%s, argument") is missing an argument.
* mesa: Always initialize transform feedback state.Chia-I Wu2010-07-061-8/+42
| | | | | | Assert ctx->Driver.NewTransformFeedback if the feature is enabled; Use the default callbacks otherwise. The rest of core mesa expects the state to be initialized.
