From: Ben Skeggs Date: Tue, 17 Mar 2009 22:22:35 +0000 (+1000) Subject: nouveau: rewrite winsys in terms of drm_api, support dri2 state tracker X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e00ae524e236afba1305150cacd634eaa1f5460b;p=mesa.git nouveau: rewrite winsys in terms of drm_api, support dri2 state tracker drm_api is a set of hooks used by the dri2 state tracker, this wraps our dri1 code around the same set of hooks. Currently the dri2 build will produce nouveau_dri2.so which you'll need to install as nouveau_dri.so if you wish to try it. The dri2 state tracker doesn't make it easy for a driver to support both paths in the same binary. --- diff --git a/src/gallium/drivers/nouveau/nouveau_winsys.h b/src/gallium/drivers/nouveau/nouveau_winsys.h index 4fcadbae3f9..ff7dd1c51c8 100644 --- a/src/gallium/drivers/nouveau/nouveau_winsys.h +++ b/src/gallium/drivers/nouveau/nouveau_winsys.h @@ -24,7 +24,7 @@ #define NOUVEAU_BUFFER_USAGE_TRANSFER (1 << 18) struct nouveau_winsys { - struct nouveau_context *nv;
