Subject: [Qemu-devel] [PATCH 0/4]: timers thread-safe stuff
Date: Mon, 5 Aug 2013 15:33:22 +0800 [thread overview]
Message-ID: <1375688006-16780-1-git-send-email-pingfank@linux.vnet.ibm.com> (raw)
The patches has been rebased onto Alex's [RFC] [PATCHv5 00/16] aio / timers: Add AioContext timers and use ppoll
permalink.gmane.org/gmane.comp.emulators.qemu/226333
For some other complied error issue, I can not finish compiling, will fix it later.
Changes since last version:
1. drop the overlap partition and leave only thread-safe stuff
2. For timers_state, since currently, only vm_clock can be read outside BQL.
There is no protection with ticks(since the protection will cost more in read_tsc path).
3. use light weight QemuEvent to re-implement the qemu_clock_enable(foo,false)
Liu Ping Fan (2):
timer: protect timers_state's clock with seqlock
timer: make qemu_clock_enable sync between disable and timer's cb
Paolo Bonzini (2):
seqlock: introduce read-write seqlock
qemu-thread: add QemuEvent
