From d4d9ec55c589156df4edc227a86b4a8c41048d58 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Tue, 11 Oct 2016 23:19:46 +0200 Subject: [PATCH] radeonsi: implement TC-compatible HTILE MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit so that decompress blits aren't needed and depth texturing needs less memory bandwidth. Z16 and Z24 are promoted to Z32_FLOAT by the driver, because TC-compatible HTILE only supports Z32_FLOAT. This doubles memory footprint for Z16. The format promotion is not visible to state trackers. This is part of TC-compatible renderbuffer compression, which has 3 parts: DCC, HTILE, FMASK. Only TC-compatible FMASK compression is missing now. I don't see a measurable increase in performance though. (I tested Talos Principle and DiRT: Showdown, the latter is improved by 0.5%, which is almost noise, and it originally used layered Z16, so at least we know that Z16 promoted to Z32F isn't slower now) Tested-by: Edmondo Tommasina Reviewed-by: Nicolai Hähnle --- src/gallium/drivers/radeon/r600_pipe_common.h | 3 + src/gallium/drivers/radeon/r600_texture.c | 67 ++++++++++++++++--- src/gallium/drivers/radeon/radeon_winsys.h | 4 ++ src/gallium/drivers/radeonsi/si_blit.c | 11 ++- src/gallium/drivers/radeonsi/si_descriptors.c | 7 +- src/gallium/drivers/radeonsi/si_shader.c | 18 ++++- src/gallium/drivers/radeonsi/si_state.c | 39 +++++++++-- src/gallium/drivers/radeonsi/si_state_draw.c | 3 +- .../winsys/amdgpu/drm/amdgpu_surface.c | 57 ++++++++++++++-- 9 files changed, 185 insertions(+), 24 deletions(-) diff --git a/src/gallium/drivers/radeon/r600_pipe_common.h b/src/gallium/drivers/radeon/r600_pipe_common.h index 290b228b73f..5cfcad688c4 100644 --- a/src/gallium/drivers/radeon/r600_pipe_common.h +++ b/src/gallium/drivers/radeon/r600_pipe_common.h @@ -245,6 +245,7 @@ struct r600_htile_info { unsigned height; unsigned xalign; unsigned yalign; + unsigned alignment; }; struct r600_texture { @@ -252,6 +253,7 @@ struct r600_texture { uint64_t size; unsigned num_level0_transfers; + enum pipe_format db_render_format; bool is_depth; bool db_compatible; bool can_sample_z; @@ -273,6 +275,7 @@ struct r600_texture { /* Depth buffer compression and fast clear. */ struct r600_htile_info htile; struct r600_resource *htile_buffer; + bool tc_compatible_htile; bool depth_cleared; /* if it was cleared at least once */ float depth_clear_value; bool stencil_cleared; /* if it was cleared at least once */ diff --git a/src/gallium/drivers/radeon/r600_texture.c b/src/gallium/drivers/radeon/r600_texture.c index 57cdbcf615d..625d091fe40 100644 --- a/src/gallium/drivers/radeon/r600_texture.c +++ b/src/gallium/drivers/radeon/r600_texture.c @@ -192,7 +192,8 @@ static int r600_init_surface(struct r600_common_screen *rscreen, struct radeon_surf *surface, const struct pipe_resource *ptex, unsigned array_mode, - bool is_flushed_depth) + bool is_flushed_depth, + bool tc_compatible_htile) { const struct util_format_description *desc = util_format_description(ptex->format); @@ -256,11 +257,22 @@ static int r600_init_surface(struct r600_common_screen *rscreen, if (!is_flushed_depth && is_depth) { surface->flags |= RADEON_SURF_ZBUFFER; + if (tc_compatible_htile && + array_mode == RADEON_SURF_MODE_2D) { + /* TC-compatible HTILE only supports Z32_FLOAT. + * Promote Z16 to Z32.
