[Pkg-xen-devel] Bug#1032480: xen: Important cherry-picks for bookworm/updates

[Elliott Mitchell]

Package: src:xen
Version: 4.17.0+46-gaaf74a532c-1
Severity: important

Two major bugs have shown with the release of new hardware from AMD.
Since the new hardware is likely to become common during the life of
Debian/bookworm, you may wish to grab them early:

ad15a0a8ca2515d8ac58edfc0bc1d3719219cb77
x86/time: prevent overflow with high frequency TSCs

Turns out the latest generation is fast enough to cause overflows.



I haven't found a patch for the other one yet.  There is some issue with
the latest generation which needs "x2apic=false" on Xen's command-line
in order to get interrupts to domain 0.  I'm guessing the latest from AMD
broke the PIC emulation.

If this isn't actually patched yet, I suspect it soon will be.  I haven't
observed anything on xen-devel, so perhaps the workaround was found too
quickly to get noticed as urgent.


Now to continuing the work on figuring out the consequences from
upgrading hardware a bit too early...
