Subject: [RFC][PATCH 0/3] smp_cond_load_acquire + cmpwait
Date: Mon, 04 Apr 2016 14:22:50 +0200 [thread overview]
Message-ID: <20160404122250.340636238@infradead.org> (raw)
As Will reminded me last week; we still had some pending changes.
A number of patches that allow arm64 to use a monitor/mwait like construct to
avoid most spin waiting.
Compile and boot tested on x86_64, but I seem to have misplaced my arm64
compiler so that part is still a rough sketch mostly.
