            Bug ID: 208611
           Summary: amdgpu crash on sharing image memory between Vulkan
                    and OpenGL
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.7.8-200.fc32.x86_64
          Hardware: x86-64

            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org

The kernel crash part of the log.

I have two programs: one (Vulkan) creates an image, allocates memory for it and
exports the memory as an fd. The second program (OpenGL) receives the fd,
imports it as a memory for a texture, and blits some data into the texture. The
Vulkan program subsequently maps the memory and reads pixel values from it.

Both programs follow the code of this ANGLE test for Vulkan-OpenGL interop very
closely:
https://github.com/pmatos/WebKit/blob/c42c49d3859ceb5d6e5c502373c8d3e371662ac4/Source/ThirdParty/ANGLE/src/tests/gl_tests/VulkanExternalImageTest.cpp#L434

It works fine with VK_FORMAT_R8G8B8A8_UNORM, but after changing it to
R8G8B8_UNORM (without the alpha) in (I'm fairly certain) all respective places,
I got corrupt image data on one run and a kernel crash on another run. Here are
some excerpts from the log:
