From 054b93e444550a72aef17115363cdef253b9ee7c Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Tue, 15 Dec 2009 22:02:47 +1000 Subject: [PATCH] drm/nv40: implement ctxprog/state generation The context programs are *very* simple compared to the ones used by the binary driver. There's notes in nv40_grctx.c explaining most of the things we don't implement. If we discover if/why any of it is required further down the track, we'll handle it then. The PGRAPH state generated for each chipset should match what NVIDIA do almost exactly (there's a couple of exceptions). If someone has a lot of time on their hands, they could figure out the mapping of object/method to PGRAPH register and demagic the initial state a little, it's not terribly important however. At time of commit, confirmed to be working at least well enough for accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46, NV49, NV4A, NV4B and NV4E. A module option has been added to force the use of external firmware blobs if it becomes required.
