From 917814dccd4354db09a1b7bf977ef2352b74c917 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Thu, 6 Oct 2016 15:21:49 -0700 Subject: anv: Allocate hiz surface Nanley Chery: (rebase) - Use isl_surf_get_hiz_surf() (amend) - Only add a HiZ surface onto a depth/stencil attachment - Add comment above HiZ surface addition - Hide HiZ behind INTEL_VK_HIZ prior to BDW - Disable HiZ for untested cases - Remove DISABLE_AUX_BIT instead of preventing it from being added Signed-off-by: Nanley Chery Reviewed-by: Jason Ekstrand Reviewed-by: Chad Versace --- src/intel/vulkan/anv_image.c | 37 ++++++++++++++++++++++++++++++++++--- 1 file changed, 34 insertions(+), 3 deletions(-) (limited to 'src/intel/vulkan/anv_image.c') diff --git a/src/intel/vulkan/anv_image.c b/src/intel/vulkan/anv_image.c index f6e86725f9..77dcd46236 100644 --- a/src/intel/vulkan/anv_image.c +++ b/src/intel/vulkan/anv_image.c @@ -28,6 +28,7 @@ #include #include "anv_private.h" +#include "util/debug.h" #include "vk_format_info.h" @@ -60,6 +61,7 @@ choose_isl_surf_usage(VkImageUsageFlags vk_usage, default: unreachable("bad VkImageAspect"); case VK_IMAGE_ASPECT_DEPTH_BIT: + isl_usage &= ~ISL_SURF_USAGE_DISABLE_AUX_BIT; isl_usage |= ISL_SURF_USAGE_DEPTH_BIT; break; case VK_IMAGE_ASPECT_STENCIL_BIT: @@ -99,6 +101,16 @@ get_surface(struct anv_image *image, VkImageAspectFlags aspect) } } +static void +add_surface(struct anv_image *image, struct anv_surface *surf) +{ + assert(surf->isl.size > 0); /* isl surface must be initialized */ + + surf->offset = align_u32(image->size, surf->isl.alignment); + image->size = surf->offset + surf->isl.size; + image->alignment = MAX(image->alignment, surf->isl.alignment); +} + /** * Initialize the anv_image::*_surface selected by \a aspect.
