Revision cc6afe2240298049585e86b1ade85efc8a7f225d authored by Paolo Bonzini on 10 October 2017, 10:12:57 UTC, committed by Thomas Gleixner on 12 October 2017, 15:10:10 UTC
Commit 594a30fb1242 ("x86/apic: Silence "FW_BUG TSC_DEADLINE disabled
due to Errata" on CPUs without the feature", 2017-08-30) was also about
silencing the warning on VirtualBox; however, KVM does expose the TSC
deadline timer, and it's virtualized so that it is immune from CPU errata.
Therefore, booting 4.13 with "-cpu Haswell" shows this in the logs:
[ 0.000000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata;
please update microcode to version: 0xb2 (or later)
Even if you had a hypervisor that does _not_ virtualize the TSC deadline
and rather exposes the hardware one, it should be the hypervisors task
to update microcode and possibly hide the flag from CPUID. So just
hide the message when running on _any_ hypervisor, not just those that
do not support the TSC deadline timer.
The older check still makes sense, so keep it.
