Bug ID: 110268
Summary: enable storageBuffer16BitAccess feature in radv for SI
and CIK
Product: Mesa
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Vulkan/radeon
Assignee: mesa-dev@lists.freedesktop.org
Reporter: shuizhuyuan...@126.com
QA Contact: mesa-dev@lists.freedesktop.org
the VK_KHR_16bit_storage extension is enabled but all features are reported as
FALSE for SI and CIK.
I found those features are only enabled with VI+ in
mesa/src/amd/vulkan/radv_device.c
as contrast, the amdvlk driver support them.
16bit storage support is important for reducing shader bandwidth and gaining
speed boost. (found 20%~50% speedup with the ncnn vulkan nerual network
benchmark)
please consider implementing storageBuffer16BitAccess feature for SI and CIK.
Thanks!
case VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_16BIT_STORAGE_FEATURES:
{
VkPhysicalDevice16BitStorageFeatures *features =
(VkPhysicalDevice16BitStorageFeatures*)ext;
bool enabled = pdevice->rad_info.chip_class >= VI;
features->storageBuffer16BitAccess = enabled;
features->uniformAndStorageBuffer16BitAccess = enabled;
features->storagePushConstant16 = enabled;
features->storageInputOutput16 = enabled && HAVE_LLVM
>= 0x900;
break;
}
