Explicit Sync gets me chubbed up bro.

You wouldn’t believe how many times I’ve fantasised about the GPU syncing up with the kernel.

Think about how hot the GPU would be when it tells the kernel it’s just about to finish (rendering).

I could just sit in my room alone, all day, curtains closed, door locked, watching the compositor display my applications without any jitter.

This is the best summary I could come up with:

In addition to all of the contributions Valve graphics engineers have been making to the open-source Radeon “RADV” Vulkan driver, they have also begun investing in improvements to the open-source Mesa NVIDIA “NVK” Vulkan driver too.

With pending patches there is now explicit GPU synchronization support working for the NVK driver in conjunction with their Gamescope compositor.

Prominent Valve Linux lead Pierre-Loup Griffais X’ed the good news on Friday night:

There is this patch to the Nouveau DRM kernel driver for handling of VM_BIND buffer object allocations with PTE kind and tile mode.

These patches have yet to be upstreamed but great to see the NVK explicit sync support on the way.

Meanwhile NVIDIA is expected to release a big binary Linux driver beta earlier this month baking their explicit sync support and other enhancements in their new driver series.
