Hello everyone,
Lately i've been trying to share memory between two cells using uio_ivshmem
driver (https://github.com/henning-schild-work/ivshmem-guest-code), as it has
been recommended here in multiple threads, in Ultrascale+ (arm64).
So firstly, i am using ivshmem-demo.bin to run on non-root cell and test
uio_ivshmem driver. I am using a customized ivshmem-demo.c from another user
that tweaked ivshmem-demo to work in arm64. When debugging this source file
(using printks), i've noticed that the code stops running when mmio_read16() is
called (the printks stop there).
Any ideas of what might be the problem??
I attach the log file of the session where i issue the commands to enable
ivshmem and the cells to share memory.
