Hi Henning,
As part of the TI SDK, we were integrating the ivhsmem_uio as external
module
from https://github.com/henning-schild-work/ivshmem-guest-code
Since the ivshmem changes in the Jailhouse, that driver no more works
(because of the vendor ID change)
Do you plan to host the updated version of the driver in this repo?
I know that the driver is already part of the siemens repo but it is
much simpler to integrate an external module in yocto.
Actually, that new driver is a complete rewrite, not just an ID update.
It allows to securely pass access to unprivileged users and provides all
features of the new ivshmem interface. For that, it requires to patch
the kernel with [1]. But given that you have to patch your kernel anyway
for other Jailhouse details and given that this is trivial in yocto, I
don't get the point of having an external module package being easier.
