Bug workaround patch
According to the Vulkan spec and a FIXME comment present in anv_ResetCommandPool (anv_cmd_buffer.c:~1100), vkResetCommandPool should not destroy the command buffers referenced by the command.
The destruction of the command buffers breaks the samples of an open source abstraction layer above Vulkan that I am making. The abstraction layer along with the samples and build instructions are available at: https://github.com/ronsaldo/abstract-gpu current master whose commit number is 04255a7a93812d94d1b8683b13f67558c7b76e54 .
The attached patch contains a quick workaround this problem that at least prevent the samples from crashing. The patch should be checked for potential memory leaks.
Sorry for not getting back to this sooner. Somehow it missed my radar. You are correct that our implementation is invalid. The patch you attached isn't a workaround it is in fact the correct patch. Please send it to the mesa-dev mailing list and I'll make sure it gets reviewed and committed.
