Using the 6.18 kernel I get the following result:
from RiscvProfile import *
a = RiscvProfile.read_cpuinfo()
a.assert_rva23_ready()
Traceback (most recent call last):
File "<python-input-8>", line 1, in <module>
a.assert_rva23_ready()
~~~~~~~~~~~~~~~~~~~~^^
File "/tmp/RiscvProfile.py", line 284, in assert_rva23_ready
raise RiscvProfileException(f'Missing extension {ext}')
RiscvProfile.RiscvProfileException: Missing extension ziccrse
The extension ziccrse is not described in the device-tree of the vendor
kernel. But it exists in the upstream device-tree. Adjusting the 6.18
kernel seems plausible.
