Tony Luck 2c86963b09 [IA64] implement ticket locks for Itanium ... Back in January 2008 Nick Piggin implemented "ticket" spinlocks for X86 (See commit 314cdbefd1). IA64 implementation has a couple of differences because of the available atomic operations ... e.g. we have no fetchadd2 instruction that operates on a 16-bit quantity so we make ticket locks use a 32-bit word for each of the current ticket and now-serving values. Performance on uncontended locks is about 8% worse than the previous implementation, but this seems a good trade for determinism in the contended case. Performance impact on macro-level benchmarks is in the noise. Signed-off-by: Tony Luck <tony.luck@intel.com>		2009-09-25 08:42:16 -07:00
