Subject: egl/dri: Add error info needed for EGL_EXT_image_dma_buf_import extension
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cfc3200a35647026a0b5cf188f378ce33802044b;p=mesa.git

egl/dri: Add error info needed for EGL_EXT_image_dma_buf_import extension

Update the DRI image interface error codes to reflect the needs of the
EGL_EXT_image_dma_buf_import extension. This means updating the existing error
code documentation and adding a new __DRI_IMAGE_ERROR_BAD_ACCESS error code
so that drivers can correctly reject unsupported pitches and offsets. Hook
the new error code up in EGL to return EGL_BAD_ACCESS.
