Hi,
How to test it:
- This series can be applied on git/andersson/remoteproc.git for-next branch (7486f29e5e60)
+ the "Restructure the rpmsg char to decorrelate the control part" series[3]
[1] https://patchwork.kernel.org/project/linux-remoteproc/list/?series=475217
[2] https://patchwork.kernel.org/project/linux-remoteproc/list/?series=505873
[3] https://patchwork.kernel.org/project/linux-remoteproc/list/?series=483793Just did test this patchset v3 again. With the same protocol
Works for me, /dev/rpmsg0 is created on NS announcement, and removed when stopping the remote processor.
I can do a repeated series of open /read/write/close, and got EBUSY if I try to open it more than once
at a time.
Firmware used for testing is derived from:
https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/ipc/openamp_rsc_table
with:
#define RPMSG_CHAN_NAME "rpmsg-raw"
Thanks Arnaud for your work.
