futarisIRCcloudI've got some free time to look at the interrupt stuff. Looks like we can inplement the vexriscv specific interrupt handler, or create a new generic litex risc-v PLIC.01:26

ambro718When doing a ready-valid pipeline, is it commonly true that the state of ready is irrelevant when valid is 0? In other words, ready might as well be called accepted (indicating if valid data was accepted)?08:47
Dolu1Else system where ready is relevant when valid is 0, can be called as "non bubble collapsing pipeline"09:04
ambro718Great, thanks.09:05
