Ok, I'll send new patch with the commit and tree.

Taking a sha1 from your own tree is useless. My point of noting the sha1 is that it must be from a non-rebasing tree which will land in Linus' tree, so that in the future it can be found again. -Daniel > > Thanks and Regards, > Dongseong > > On Thu, Apr 21, 2016 at 7:02 PM, Emil Velikov <emil.l.velikov@gmail.com> > wrote: > > > On 21 April 2016 at 16:32, Dongseong Hwang <dongseong.hwang@intel.com> > > wrote: > > > Follow-up of kernel patch: > > https://lists.freedesktop.org/archives/dri-devel/2015-July/086041.html > > > > > > The Kodi/XBMC and ChromeOS developers want to transcode NV12 to RGB > > > with OpenGL shaders, importing the two source planes through > > > EGL_EXT_image_dma_buf_import.

Follow-up of kernel patch: https://lists.freedesktop.org/archives/dri-devel/2015-July/086041.html The Kodi/XBMC and ChromeOS developers want to transcode NV12 to RGB with OpenGL shaders, importing the two source planes through EGL_EXT_image_dma_buf_import. That requires importing the Y plane as an R8 EGLImage and the UV plane as either an RG88 or GR88 EGLImage.
