From c51d125d1851b76fbee5a0d99d81e92eac705939 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 27 Dec 2018 19:37:13 -0800 Subject: [PATCH] v3d: Fix stencil sampling from a separate-stencil buffer. When the sampler view is in sample-stencil mode, we need to return uint stencil values. To do that, fill in the format table to return R8I, and have the sampler view point at the separate stencil buffer. Fixes dEQP-GLES31.functional.stencil_texturing.format.depth32f_stencil8_2d --- src/gallium/drivers/v3d/v3dx_format_table.c | 1 + src/gallium/drivers/v3d/v3dx_state.c | 6 ++++++ 2 files changed, 7 insertions(+) diff --git a/src/gallium/drivers/v3d/v3dx_format_table.c b/src/gallium/drivers/v3d/v3dx_format_table.c index 80f0dc6..18a1a86 100644 --- a/src/gallium/drivers/v3d/v3dx_format_table.c +++ b/src/gallium/drivers/v3d/v3dx_format_table.c @@ -153,6 +153,7 @@ static const struct v3d_format format_table[] = { /* Pretend we support this, but it'll be separate Z32F depth and S8. */ FORMAT(Z32_FLOAT_S8X24_UINT, D32F, DEPTH_COMP32F, SWIZ_XXXX, 32, 1), + FORMAT(X32_S8X24_UINT, S8, R8UI, SWIZ_XXXX, 16, 1), #else FORMAT(S8_UINT_Z24_UNORM, ZS_DEPTH24_STENCIL8, DEPTH24_X8, SWIZ_XXXX, 32, 1), FORMAT(X8Z24_UNORM, ZS_DEPTH24_STENCIL8, DEPTH24_X8, SWIZ_XXXX, 32, 1), diff --git a/src/gallium/drivers/v3d/v3dx_state.c b/src/gallium/drivers/v3d/v3dx_state.c index 47b7ad0..9560d3f 100644 --- a/src/gallium/drivers/v3d/v3dx_state.c +++ b/src/gallium/drivers/v3d/v3dx_state.c @@ -774,6 +774,12 @@ v3d_create_sampler_view(struct pipe_context *pctx, struct pipe_resource *prsc, so->base.reference.count = 1; so->base.context = pctx; + if (rsc->separate_stencil && + cso->format == PIPE_FORMAT_X32_S8X24_UINT) { + rsc = rsc->separate_stencil; + prsc = &rsc->base; + } + /* V3D still doesn't support sampling from raster textures, so we will * have to copy to a temporary tiled texture. */ -- 2.7.4
