[capture] gfxreconstruct can't capture frame in vkcube or furmark with debian os

[EthanZhang516]

Describe the capture bug:
File did not contain any frames after capture in Debian GNU/Linux 12 (bookworm) ,Linux version 6.1.44

Build Environment:
try dev and v1.0.4

Capture Settings:
GFXRECON_MEMORY_TRACKING_MODE=page_guard VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_gfxreconstruct VK_LAYER_PATH=/mnt/disk/gfxr_release/gfxreconstruct/build/layer GFXRECON_CAPTURE_FILE=/mnt/disk/gfxr/vkcube.gfxr GFXRECON_LOG_LEVEL=debug GFXRECON_CAPTURE_FRAMES=1-19 GFXRECON_LOG_DETAILED=true GFXRECON_CAPTURE_FILE_TIMESTAMP=false vkcube --c 100

[panos-lunarg]

Can you upload the capture file?

[bradgrantham-lunarg]

You can also try debug.gfxrecon.capture_file_flush true. In the case that you are exiting the program by killing it through the WM or with CTRL-C and not , the in-memory libc stdio buffers may be lost if atexit wasn't called. capture_file_flush flushes the capture file after writing every Vulkan command.

[EthanZhang516]

Can you upload the capture file?
This is capture file from cmd "GFXRECON_MEMORY_TRACKING_MODE=page_guard VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_gfxreconstruct VK_LAYER_PATH=/mnt/disk/gfxr_release/gfxreconstruct/build/layer GFXRECON_CAPTURE_FILE=/mnt/disk/gfxr/vkcube.gfxr GFXRECON_LOG_LEVEL=debug GFXRECON_CAPTURE_FRAMES=1-19 GFXRECON_LOG_DETAILED=true GFXRECON_CAPTURE_FILE_TIMESTAMP=false vkcube --c 100"

Thank you ,and I try this command with GFXRECON_CAPTURE_FILE_FLUSH=true, but there is no frame in capture file too.
my cmd is "GFXRECON_MEMORY_TRACKING_MODE=page_guard VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_gfxreconstruct VK_LAYER_PATH=/mnt/disk/gfxr_release/gfxreconstruct/build/layer GFXRECON_CAPTURE_FILE=/mnt/disk/gfxr/vkcube_file_flush.gfxr GFXRECON_LOG_LEVEL=debug GFXRECON_CAPTURE_FRAMES=1-19 GFXRECON_CAPTURE_FILE_TIMESTAMP=false GFXRECON_CAPTURE_FILE_FLUSH=true vkcube --c 100"

Looking into the json file generated from the uploaded file, the "frame loop" commands look like this:

{"index":629,"function":{"name":"vkWaitForFences","thread":1,"return":"VK_SUCCESS","args":{"device":5,"fenceCount":1,"pFences":[7],"waitAll":true,"timeout":18446744073709551615}}}

I did a capture of vkcube using the same gfxr parameters described here and the frame loop commands look like this:

{"index":263,"function":{"name":"vkWaitForFences","thread":1,"return":"VK_SUCCESS","args":{"device":5,"fenceCount":1,"pFences":[7],"waitAll":true,"timeout":18446744073709551615}}}

{"index":266,"meta":{"name":"FillMemoryCommand","args":{"memory_id":32,"offset":0,"size":4096,"data":"[Binary data]"}}}
{"index":267,"function":{"name":"vkQueueSubmit","thread":1,"sub_index":34,"return":"VK_SUCCESS","args":{"queue":6,"submitCount":1,"pSubmits":[{"sType":"VK_STRUCTURE_TYPE_SUBMIT_INFO","waitSemaphoreCount":1,"pWaitSemaphores":[8],"pWaitDstStageMask":1024,"commandBufferCount":1,"pCommandBuffers":[43],"signalSemaphoreCount":1,"pSignalSemaphores":[9],"pNext":null}],"fence":7}}}
{"index":268,"function":{"name":"vkQueuePresentKHR","thread":1,"sub_index":35,"return":"VK_SUCCESS","args":{"queue":6,"pPresentInfo":{"sType":"VK_STRUCTURE_TYPE_PRESENT_INFO_KHR","waitSemaphoreCount":1,"pWaitSemaphores":[9],"swapchainCount":1,"pSwapchains":[13],"pImageIndices":1,"pResults":null,"pNext":null}}}}
{"frame":{"marker_type":"EndMarker","frame_number":17}}

The demo_draw from cube.c (checked out from the latest main) looks like this:

vkWaitForFences
vkResetFences
vkAcquireNextImageKHR
vkQueueSubmit
vkQueuePresentKHR

I think this raises a few questions regarding the uploaded capture file.

1. Why are there 2 vkWaitForFences
2. The order in general looks modified
3. vkQueuePresentKHR is missing. I can't see think of any reason that this command is called but not captured in the file.
4. vkAcquireNextImageKHR vkImportSemaphoreFdKHR is never called from cube.c

Is it possible that you have modified cube.c resulting in this behavior?

No，I didn't modify cube.c ,I get vkcube using apt install libvulkan1 vulkan-tools. how do you genrate vkcube? I can try the way you get it

[panos-lunarg]

I build it locally from the Vulkan-Tools github repo

New capture file has same pattern. Hard to explain.

Selected GPU 0: Mali-G720-Immortalis, type: IntegratedGpu Just noticed this. Are you capturing on a phone?

not a phone,it's an Arm development board,orion o6,using arm gpu
