One related issue with explicit sync using sync_file is that combined CPUs/GPUs (the CPU cores *are* the GPU cores) that do all the rendering in userspace (like llvmpipe but for Vulkan and with extra instructions for GPU tasks) but need to synchronize with other drivers/processes is that there should be some way to create an explicit fence/semaphore from userspace and later signal it. This seems to conflict with the requirement for a sync_file to complete in finite time, since the user process could be stopped or killed.
Any ideas? Jacob Lifshay _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
