From: Eric Anholt Date: Thu, 26 Sep 2013 19:01:56 +0000 (-0700) Subject: dri: Move API version validation into dri/common. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=083f66fdd6451648fe355b64b02b29a6a4389f0d;p=mesa.git dri: Move API version validation into dri/common. i965, i915, radeon, r200, swrast, and nouveau were mostly trying to do the same logic, except where they failed to. Notably, swrast had code that appeared to try to enable GLES1/2 but forgot to set api_mask (thus preventing any gles context from being created), and the non-intel drivers didn't support MESA_GL_VERSION_OVERRIDE. nouveau still relies on _mesa_compute_version(), because I don't know what its limits actually are, and gallium drivers don't declare limits up front at all. I think I've heard talk about doing so, though. v2: Compat max version should be 30 (noted by Ken) Drop r100's custom max version check, too (noted by Emil Velikov) Reviewed-by: Kenneth Graunke --- diff --git a/src/gallium/state_trackers/dri/common/dri_screen.c b/src/gallium/state_trackers/dri/common/dri_screen.c index 779741e32e3..92cac73d5bc 100644 --- a/src/gallium/state_trackers/dri/common/dri_screen.c +++ b/src/gallium/state_trackers/dri/common/dri_screen.c @@ -438,6 +438,19 @@ dri_init_screen_helper(struct dri_screen *screen, dri_postprocessing_init(screen);
