  [PATCH v3 00/17] Add watchdog support to arm/virt board
  https://patchew.org/QEMU/20260624102830.1355552-1-imammedo@redhat.com/

patches were basically rewritten to make changes simpler/easier to reson about.

patch 6/6 is partial fix with open question:

sbsa-gwdt currently mantains WVC in since VM start ticks, which works fine under
TCG. However under KVM those system counter domains diverge and CNTPCT in guest
starts to return host's value. As result WCV reads/writes got mixed up with
QEMU still assuming VM timeframe while guest using host's one.
Question is how should we fix it?

Igor Mammedov (6):
  sbsa-gwdt: reduce code ident
  arm: gwdt: consolidate clear WS0 and WS1 on explicit refresh
  arm: gwdt: simplify WCV update condition
  sbsa-gwdt: rename sbsa_gwdt_update_timer() to
    sbsa_gwdt_wor_update_timer()
  sbsa-gwdt: don't arm timer for compare values above INT64_MAX
  sbsa-gwdt: reschedule timer on direct WCV load
