Support for bufferDeviceAddressCaptureReplay feature of VK_KHR_buffer_device_address (for RenderDoc 1.36 raytracing capture support)..

[oscarbg]

Hi,
new Renderdoc 1.36 adds support for "Raytracing capture" of both DX12 and Vulkan programs..
see "Raytracing capture" chapter in https://github.com/baldurk/renderdoc/releases/tag/v1.36 ..
I have been testing with both samples:

https://github.com/KhronosGroup/Vulkan-Samples/tree/main/samples/extensions/ray_tracing_basic
https://github.com/KhronosGroup/Vulkan-Samples/tree/main/samples/extensions/ray_queries

both samples run ok with AMDVLK 2024.q4.3:

./vulkan_samples sample raytracing_basic
./vulkan_samples sample ray_queries

but both fail to capture:
for example on Renderdoc 1.35 trying to capture "raytracing_basic" it failed with:

[error] [framework/core/device.cpp:155] Required device extension VK_KHR_deferred_host_operations not available, cannot run
[error] [framework/core/device.cpp:155] Required device extension VK_KHR_buffer_device_address not available, cannot run
[error] [framework/core/device.cpp:155] Required device extension VK_KHR_ray_tracing_pipeline not available, cannot run
[error] [framework/core/device.cpp:155] Required device extension VK_KHR_acceleration_structure not available, cannot run
[error] [framework/platform/platform.cpp:149] Error Message: Extensions not present : ERROR_EXTENSION_NOT_PRESENT
[error] [framework/platform/platform.cpp:150] Failed when running application raytracing_basic

with 1.36 fails with :

[error] [framework/core/device.cpp:155] Required device extension VK_KHR_buffer_device_address not available, cannot run
[error] [framework/platform/platform.cpp:149] Error Message: Extensions not present : ERROR_EXTENSION_NOT_PRESENT
[error] [framework/platform/platform.cpp:150] Failed when running application raytracing_basic

this is due to needing support from AMDVLK for "bufferDeviceAddressCaptureReplay" feature of VK_KHR_buffer_device_address..

this is my report showing no support for it:
https://vulkan.gpuinfo.org/displayreport.php?id=35585#features_extensions
Nvidia for example supports bufferDeviceAddressCaptureReplay..

@oscarbg what GPU are you using? bufferDeviceAddressCaptureReplay support is relying on gfxip:
https://github.com/GPUOpen-Drivers/xgl/blob/62710fd4e7ccc159a3609aa4c307a81ac0a8453c/icd/api/vk_physical_device.cpp#L5915

Gfx1036.. raphael.. zen4 igpu.. rdna2..
At least radv on this igpu exposes it..

@jinjianrong - it's not really clear why supportCaptureReplay is disabled for GFX10 APU parts, perhaps it is to do with memory mappings on these ASICs, but I think we should probably confirm internally if it really does need to be disabled.
