When GPU crashes aren't reproducable in renderdoc, it helps to have someway to figure out what exactly is going on when a crash happens or what operation caused it. Add a checkpoint system that reports the GPU execution state in perfetto in time with actual GPU execution, and use flow events to show the event's path through execution, vulkan record and executor record stages.
Full pipeline barriers between every RP can be extremely expensive on HW, by analysing the inputs and outputs of a draw it's possible to construct a much more optimal barrier that only syncs what is neccessary.
This can reuse a fair bit of the now-commonised Maxwell 3D code and mostly consists of compute-specific pipeline code which was deemed not suitable for being commonised (e.g. descriptor update code is somewhat duplicated). Of note is how compute lacks any active state at all de to its use of QMDs which bundle up all state into a single object in memory.
