IPC Souce Missing #48

Open Fishwaldo opened 1 year ago

Fishwaldo commented 1 year ago

Hi, we have the header bl808_ipc.h present, but the source for IPC is missing. I found a copy in the bl_linux repo, but wondering if it could be added to this repo?

It is in refactoring not used now, so removed.

Fishwaldo commented 1 year ago

any ETA?

sakumisu commented 1 year ago

Do you prepare to port with rpmsg or openmap? Maybe uncertain time.

Fishwaldo commented 1 year ago

Using rpmsg-lite.

if you API is not completed yet, can I make a suggestion. In the old implementation, you divided the 32 interupt Sources equally between the 2 other CPU's (so we had 16 "sources" per CPU). In the new implementation, why dont you reserve IPC_INT_SRC_BIT31 as a flag to indicate which CPU sent the IPC, and that gives applications 31 sources to use for signalling instead of 16.

If both cpu trigger int, one bit cannot work.
