Title:
[Patch][Raven 2] kernel 5.0.0 cannot boot because of psp response
Status in amd:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
Description:
Raven 2 platform fails to boot on ubuntu 19.04 (disco) with kernel
5.0.0. The issue is related to a fixed patch in linux-mainline about
psp response code status.
In some cases, psp response status is not 0 even there is no problem
while the command is submitted. Some version of PSP FW doesn't write 0
to that field. So here we would like to only print a warning instead
of an error during psp initialization to avoid breaking hw_init and it
doesn't return -EINVAL.
Steps:
1. Install Ubuntu 19.04 daily build on AMD Raven 2 platform (reproduced with
2019.03.18 version)
2. Reboot and it fails at kernel initialization.
Current patch status:
A patch has already accepted in the linux mainline. (id:
