Submit current command buffer in wined3d_context_vk_get_command_buffer() and return a new one if the total size of retired buffer objects on that command buffer crosses a predefined threshold.

Should we guard "retired_bo_counter" against overflow? On 32-bit builds that has a maximum of 4GiB, which is perhaps not as much as it once was in terms of VRAM.

I'd prefer not having the WINED3D_RETIRED_BO_COUNTER_THRESHOLD #define in the middle of a structure. Perhaps next to the other allocator constants (i.e., WINED3D_ALLOCATOR_CHUNK_SIZE and the like) would be a good place. I think "retired_bo_counter" is perhaps a little awkward, in the sense that it doesn't count the number of retired bo's, but tracks their size; "retired_bo_size", perhaps?
In terms of the commit message, it's perhaps helpful to mention that one way this can occur is by the application doing resource updates without flushing either explicitly or implicitly, causing retired staging bo's for the current command buffer to accumulate.

Right, that wouldn’t hurt even if it’s not that likely to happen, would you mind if I simply changed it to VkDeviceSize instead of doing overflow checks?

I think that's fine too.
