By calling radeon_draw_buffers (which sets the necessary flags in radeon->NewGLState) and revalidating if NewGLState is non-zero in r200TclPrimitive. This fixes an assert in libdrm (the color-/ depthbuffer was changed but not yet validated) and and stops the kernel cs checker from complaining about them (when they're too small).
Thanks to Mario Kleiner for the hint to call radeon_draw_buffer (instead of my half-broken hack). v2: Also fix the swtcl r200 path. Cc: Mario Kleiner <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> --- I've also tested on my rv570 agp. r300c seems to suffer from the same problem: it crashes glxgears with and without this patch. r300g seems to be fine. I'll see whether I can create a r300c patch, too (after this patch survived review). Please review and apply.
