<div dir="ltr">So I have been implementing syncing mechanisms to yuzu's switch emulator, aka Tegra X1 emulation and I already have: Semaphores, Syncpoints and Queries to some extent. I'm missing the barriers (GPU waits for CPU):<div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"></div><div>I got this from RE:</div><div><span style="color:rgb(131,148,150);font-family:Consolas,"Liberation Mono",Menlo,Courier,monospace;font-size:14px;white-space:pre-wrap;background-color:rgb(47,49,54)">Barrier mode has priority (from highest to lowest):
1) 0x08 sets needsWfi=0 -> highest priority, does puller refcnt + split(0,0) + 0x100 NoOperation + rest of cmds + split(1,1)
2) 0x01 sets needsWfi=0 -> uses 0x0110 Serialize/"WaitForIdle"
3) 0x02 sets needsWfi=1 -> uses 0xDE0 (??)
4) 0x04 sets needsWfi=1 -> uses 0xF7C (??) <-- tile related? Used by nvnQueue_ctrlTiledDownsample
5) nothing; sets needsWfi=0</span> </div><div> Do you guys know any info on this and how the GPU must behave in each situation. For instance, on Serialize, what should the GPU be waiting for? I do know you guys use that one not sure on the rest.<br></div></div>
