IPC Souce Missing

Open Fishwaldo opened this issue 2 years ago • 6 comments

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.

any ETA?

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

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.
