From f8d5b377c8b1452c71d2766becad881f5541cda1 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 7 Jul 2017 06:56:57 +0100 Subject: radv: set cb base tile swizzles for MRT speedups (v4) This patch uses addrlib to workout the tile swizzles according to the surface index. It seems to produce the same values as amdgpu-pro for the deferred test. v2: don't apply swizzle to CMASK. the eg docs don't mention it, and we clearly don't align cmask for that. v3: disable surf index for dedicated images, as these will most likely be shared, and I don't think the metadata has space for this info in it yet. v4: update for shareable images, rename combined_swizzle to tile_swizzle This gets the deferred demo from 730->950fps on my rx480. (dcc cmask elim predication patches get it further) Reviewed-by: Bas Nieuwenhuizen Signed-off-by: Dave Airlie --- src/amd/vulkan/radv_device.c | 7 ++++++- src/amd/vulkan/radv_image.c | 11 ++++++++++- src/amd/vulkan/radv_private.h | 2 ++ 3 files changed, 18 insertions(+), 2 deletions(-) (limited to 'src/amd/vulkan') diff --git a/src/amd/vulkan/radv_device.c b/src/amd/vulkan/radv_device.c index 2670d47fdb8..3b405838f39 100644 --- a/src/amd/vulkan/radv_device.c +++ b/src/amd/vulkan/radv_device.c @@ -2814,7 +2814,8 @@ radv_initialise_color_surface(struct radv_device *device, } cb->cb_color_base = va >> 8; - + if (device->physical_device->rad_info.chip_class < GFX9) + cb->cb_color_base |= iview->image->surface.u.legacy.tile_swizzle; /* CMASK variables */ va = device->ws->buffer_get_va(iview->bo) + iview->image->offset; va += iview->image->cmask.offset; @@ -2823,6 +2824,8 @@ radv_initialise_color_surface(struct radv_device *device, va = device->ws->buffer_get_va(iview->bo) + iview->image->offset; va += iview->image->dcc_offset; cb->cb_dcc_base = va >> 8; + if (device->physical_device->rad_info.chip_class < GFX9) + cb->cb_dcc_base |= iview->image->surface.u.legacy.tile_swizzle; uint32_t max_slice = radv_surface_layer_count(iview); cb->cb_color_view = S_028C6C_SLICE_START(iview->base_layer) | @@ -2838,6 +2841,8 @@ radv_initialise_color_surface(struct radv_device *device, if (iview->image->fmask.size) { va = device->ws->buffer_get_va(iview->bo) + iview->image->offset + iview->image->fmask.offset; cb->cb_color_fmask = va >> 8; + if (device->physical_device->rad_info.chip_class < GFX9) + cb->cb_color_fmask |= iview->image->surface.u.legacy.tile_swizzle; } else { cb->cb_color_fmask = cb->cb_color_base; } diff --git a/src/amd/vulkan/radv_image.c b/src/amd/vulkan/radv_image.c index 17ee74b5f5b..a8af4fd6d68 100644 --- a/src/amd/vulkan/radv_image.c +++ b/src/amd/vulkan/radv_image.c @@ -32,6 +32,7 @@ #include "sid.h" #include "gfx9d.h" #include "util/debug.h" +#include "util/u_atomic.h" static unsigned radv_choose_tiling(struct radv_device *Device, const struct radv_image_create_info *create_info) @@ -210,6 +211,8 @@ si_set_mutable_tex_desc_fields(struct radv_device *device, va += base_level_info->offset; state[0] = va >> 8; + if (chip_class < GFX9) + state[0] |= image->surface.u.legacy.tile_swizzle; state[1] &= C_008F14_BASE_ADDRESS_HI; state[1] |= S_008F14_BASE_ADDRESS_HI(va >> 40); state[3] |= S_008F1C_TILING_INDEX(si_tile_mode_index(image, base_level, @@ -225,7 +228,8 @@ si_set_mutable_tex_desc_fields(struct radv_device *device, meta_va += base_level_info->dcc_offset; state[6] |= S_008F28_COMPRESSION_EN(1); state[7] = meta_va >> 8; - + if (chip_class < GFX9) + state[7] |= image->surface.u.legacy.tile_swizzle; } } @@ -473,6 +477,8 @@ si_make_texture_descriptor(struct radv_device *device, } fmask_state[0] = va >> 8; + if (device->physical_device->rad_info.chip_class < GFX9) + fmask_state[0] |= image->surface.u.legacy.tile_swizzle; fmask_state[1] = S_008F14_BASE_ADDRESS_HI(va >> 40) | S_008F14_DATA_FORMAT_GFX6(fmask_format) | S_008F14_NUM_FORMAT_GFX6(num_format); @@ -792,6 +798,9 @@ radv_image_create(VkDevice _device, image->shareable = vk_find_struct_const(pCreateInfo->pNext, EXTERNAL_MEMORY_IMAGE_CREATE_INFO_KHR) != NULL; + if (!vk_format_is_depth(pCreateInfo->format) && !create_info->scanout && !image->shareable) { + image->info.surf_index = p_atomic_inc_return(&device->image_mrt_offset_counter) - 1; + } radv_init_surface(device, &image->surface, create_info); diff --git a/src/amd/vulkan/radv_private.h b/src/amd/vulkan/radv_private.h index 2f633b4dbd9..e1fb5565494 100644 --- a/src/amd/vulkan/radv_private.h +++ b/src/amd/vulkan/radv_private.h @@ -547,6 +547,8 @@ struct radv_device { /* Backup in-memory cache to be used if the app doesn't provide one */ struct radv_pipeline_cache * mem_cache; + + uint32_t image_mrt_offset_counter; }; struct radv_device_memory { -- cgit v1.2.3
