Subject: [patch 0/2] x86/cpu/amd: Fixup the topology rework fallout
Date: Wed, 10 Apr 2024 21:45:25 +0200 (CEST) [thread overview]
Message-ID: <20240410194002.909839385@linutronix.de> (raw)
In-Reply-To: <87il0p2era.ffs@tglx>
Testing at Collabora unearthed two issues in the new AMD topology parser
code:
1) The CPUID 0x80000008 parser initializes the wrong topology domain
level.
2) The NODEID_MSR parser uses bitfields in a union wrongly which results
in reading out the wrong value and finally in a division by zero.
Many thanks to Laura for helping to debug this issue.
