Subject: [dpdk-dev] [PATCH v3 0/3] rwlock: reimplement rwlock with atomic and add relevant perf test case
Date: Thu, 14 Mar 2019 21:15:01 +0800	[thread overview]
Message-ID: <1552569304-74817-1-git-send-email-joyce.kong@arm.com> (raw)
Message-ID: <20190314131501.Fm-6NMg8QCNlbLyj0yqNomGmR-jd0ft0VnIFC4Gu-qw@z> (raw)
In-Reply-To: <1544672265-219262-2-git-send-email-joyce.kong@arm.com>

v3: Fix headline format error.

v2: Rebase and modify the rwlock test case to address the comments in v1.

v1: Reimplement rwlock with atomic builtins, and add a rwlock perf test
    on all available cores to benchmark the improvement.

	We tested the patches on three arm64 platforms.
	ThundeX2 gained 20% performance, Qualcomm gained 36% and
	the 4-Cortex-A72 Marvell MACCHIATObin gained 19.6%.
	
	Below is the detailed test result on ThunderX2:

	*** rwlock_autotest without atomic builtins ***
	Rwlock Perf Test on 128 cores...
	Core [0] count = 281
	Core [1] count = 252
	Core [2] count = 290
	Core [3] count = 259
	Core [4] count = 287
	...
	Core [209] count = 3
	Core [210] count = 31
	Core [211] count = 120
	Total count = 18537

	*** rwlock_autotest with atomic builtins ***
	Rwlock Perf Test on 128 cores...
	Core [0] count = 346
	Core [1] count = 355
	Core [2] count = 259
	Core [3] count = 285
	Core [4] count = 320
	...
	Core [209] count = 2
	Core [210] count = 23
	Core [211] count = 63
	Total count = 22194
