Subject: [PATCH 01/13] hperf_hmp: add new config for arm and arm64.
Date: Fri, 06 Nov 2015 15:02:35 +0300 [thread overview]
Message-ID: <1446811367-23783-2-git-send-email-a.krasnov@samsung.com> (raw)
In-Reply-To: <1446811367-23783-1-git-send-email-a.krasnov@samsung.com>
New config option which enables new scheduler logic: HPERF_HMP. Also
adds the following options:
'HPERF_HMP_DEBUG': enables extra runtime checks of balancing parameteres.
'HMP_FAST_CPU_MASK': CPU mask of A15 cluster(in hex string).
'HMP_SLOW_CPU_MASK': CPU mask of A7 cluster(in hex string).
