[Freedreno] [PATCH 1/2] nir: allow texture offsets with cube maps

GL doesn't have this, but some hardware supports it. This is convenient for lowering tg4 to plain texture calls, which is necessary on Adreno A4xx hardware. Signed-off-by: Ilia Mirkin --- src/compiler/nir/nir.h | 15 +-- 1 file changed, 13 insertions(+), 2

[Freedreno] [PATCH 2/2] freedreno/ir3: add a pass to lower tg4 to txl, enable gather on a4xx

Unfortunately Adreno A4xx hardware returns incorrect results with the GATHER4 opcodes. As a result, we have to lower to 4 individual texture calls (txl since we have to force lod to 0). We achieve this using offsets, including on cube maps which normally never have offsets. Signed-off-by: Ilia

[Freedreno] [PATCH] freedreno/a4xx: add stencil texturing support

Copied from a5xx, should be identical. Signed-off-by: Ilia Mirkin --- docs/features.txt| 6 ++--- src/gallium/drivers/freedreno/a4xx/fd4_emit.c| 2 ++ src/gallium/drivers/freedreno/a4xx/fd4_format.c | 11 +---
