[Nouveau] [PATCH v2 0/3] ARB_viewport_array for nvc0
This patch-series implements the ARB_viewport_array for nvc0 and does
a little house-cleanig afterwords.
V2:
Add Release-Notes, mark this in GL3 as done for nvc0
Don't mark the scissors dirty when we don't need to do that
Tobias Klausmann (3):
nvc0: implement multiple viewports/scissors, enable ARB_viewport_array
docs: update GL3.txt, relnotes: mark GL_ARB_viewport_array as done for
nvc0
nv50/ir: Remove NV50_SEMANTIC_VIEWPORTINDEX

[Nouveau] [PATCH v2 1/3] nvc0: implement multiple viewports/scissors, enable ARB_viewport_array
I've made a few small fixes to this -- you forget to set the scissors/viewports dirty to ~0 on context switch, and also marking the first scissor dirty after a 3d blit (which I was forgetting to do on nv50 as well... oops). I'll push this out shortly with my modifications. Thanks for the contribution! -ilia On Sun, Jun 15, 2014 at 3:24 PM, Tobias Klausmann <tobias.johannes.klausmann at mni.thm.de> wrote:> Signed-off-by: Tobias Klausmann <tobias.johannes.klausmann at mni.thm.de> > --- > src/gallium/drivers/nouveau/nvc0/nvc0_context.h | 7 +- > src/gallium/drivers/nouveau/nvc0/nvc0_program.c | 2 +- > src/gallium/drivers/nouveau/nvc0/nvc0_screen.c | 20 ++-- > src/gallium/drivers/nouveau/nvc0/nvc0_screen.h | 3 + > src/gallium/drivers/nouveau/nvc0/nvc0_state.c | 27 +++-- > .../drivers/nouveau/nvc0/nvc0_state_validate.c | 116 +++++++++++++-------- > 6 files changed, 112 insertions(+), 63 deletions(-) > > diff --git a/src/gallium/drivers/nouveau/nvc0/nvc0_context.h b/src/gallium/drivers/nouveau/nvc0/nvc0_context.h > index 76416a0..674dd3c 100644 > --- a/src/gallium/drivers/nouveau/nvc0/nvc0_context.h > +++ b/src/gallium/drivers/nouveau/nvc0/nvc0_context.h > @@ -178,8 +178,11 @@ struct nvc0_context { > struct pipe_blend_color blend_colour;
