[PATCH v2 00/24] [uq/master] Patch queue, part II

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Version 2 of part II. Changes:
 - Fixed "Unconditionally reenter kernel after IO exits" to take
   self-INIT into account
 - Fixed misplaced hunk in "Fix race between timer signals and vcpu
   entry under !IOTHREAD" (rebase artifact)
 - Factor out block_synchronous_signals (analogue to block_io_signals)
 - Additional fix to break out of SMP VCPU loop on pending IO event
 - Fork qemu_kvm_init_cpu_signals over CONFIG_IOTHREAD
 - Additional cleanup, flattening the main loop

Hope I addressed all review comments (except for passing env to
qemu_cpu_kick_self which I think is better as it is).

Thanks,
Jan
