Bug ID: 109334
Summary: OpenGL-OpenCL interop support
Product: Mesa
Version: unspecified
Hardware: Other
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Gallium/StateTracker/Clover
Assignee: mesa-dev@lists.freedesktop.org
Reporter: yalt...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org
OpenGL-OpenCL interop, which as far as I understand is governed by the
cl_khr_gl_sharing [1, 2] extension, allows applications to use OpenGL buffer,
texture and renderbuffer objects as OpenCL memory objects.
I use it in a video capturing utility to perform OpenCL-accelerated color
conversions of OpenGL textures. Looks like it's not supported by Mesa's OpenCL
implementation.
I'm not at all familiar with the Mesa codebase so I'm not sure how much effort
supporting this would require.
