Running piglit gpu.py, the X server crashes because loader is NULL in st/dri's dri2_lookup_egl_image(), see backtrace below. Patching it to return NULL in that case, piglit runs to completion, but some Mesa errors appear in the X server's stderr: Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture2DEXT(non existant texture) Mesa: 2 similar GL_INVALID_OPERATION errors Mesa: User error: GL_INVALID_OPERATION in glTexSubImage2D(invalid texture image) Mesa: 4 similar GL_INVALID_OPERATION errors Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture2DEXT(non existant texture) And some test windows leave artifacts on the screen.

Here the error you have is in the code to create pixmaps: glamor creates an argb8888 gbm bo, then import the bo as an EGLImage. It then get a texture from the image and use the texture for the pixmap. This code is used to force all pixmaps to be argb8888, whereas by creating the texture directly you can't assert this. The bug you hit comes from this code. I already corrected a bug recently in gallium code when it was importing the gbm bo as EGLImage. A field wasn't copied. I can't say from where the bug you face comes (glamor or Mesa), but it shouldn't come from the code to import dma-bufs, since it is used only with the dri3 call to convert a fd to a pixmap.
