From: Gurchetan Singh Date: Thu, 7 Nov 2019 01:18:13 +0000 (-0800) Subject: dri_util: add driImageFormatToSizedInternalGLFormat function X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf576772ab4d9e76dae716640bed6de879f19567;p=mesa.git dri_util: add driImageFormatToSizedInternalGLFormat function This is needed to implement the EXT_EGL_image_storage spec: "If is GL_TEXTURE_2D, then the resultant texture must have a sized internal format which is colorspace and size compatible with the dma-buf. If the GL is unable to determine such a format, the error INVALID_OPERATION is generated."
