These are things that I keep getting hung up on. It is clear how gdb/perf work for example, by using the ptrace/open_perf_event syscalls in the linux kernel. However when it comes to gpu programming there seems to be few tools that aren't vendor specific and it is completely unclear how they work to a non-gpu expert. To open up gpu programming to a larger audience, how to perform debugging/profiling tasks should be documented better.

I presume there is some sort of synchronizing primitive in vulkan that could be used for debugging to step through the code, but how would you sample the gpu stack for example?

Non vengono indicati file, test o punti di ingresso. Inizia ricercando workflow di debugging e profiling GPU indipendenti dal fornitore, comprese le questioni relative alla sincronizzazione Vulkan e al campionamento dello stack GPU sollevate nell’issue. Il lavoro è considerato completato quando viene aggiunta documentazione che spiega approcci pratici al debugging e al profiling per chi non è esperto di GPU.
