[PATCH 0/6] Hexagon: fix lock, priv bugs
Posted by Brian Cain 1 week, 5 days ago
Testing with h2 and linux has uncovered some bugs in the way the locks are
implemented and privileged instructions.

Note that this will be rebased to make adjustments when the *next_pc removals
land.  See https://lore.kernel.org/qemu-devel/20261008211005.1853542-1-brian.cain@oss.qualcomm.com/

Brian Cain (6):
  target/hexagon: check privilege mode for system instructions
  target/hexagon: wake K0 and TLB lock waiters
  target/hexagon: fix stale PC on k0lock wait resume
  target/hexagon: halt on tlblock when the TLB lock is contended
  target/hexagon: set a started thread's enable bit when start retires
  tests/functional/hexagon: add MiniVM, lock tests
