Hello Greg,
I tested 6.1.69-rc1 on Kalray kvx arch (not upstream yet), just to let you know everything works in our CI: running on real hw + qemu, running tests using lots of interfaces (usb, qsfp ethernet, eMMC, PCIe endpoint+RC, SPI, remoteproc, uart). LTP and uClibc-ng testsuite are also run without any regression.
Everything looks fine to us.
Thanks!
