From: Kan Liang Date: Tue, 29 Aug 2017 17:11:10 +0000 (-0400) Subject: perf mem: Support physical address X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c35aeb9dfe512422ca9ea28aae692c8f1d052b2d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf mem: Support physical address Add option phys-data in "perf mem" to record/report physical address. The default mem sort order for physical address is changed accordingly.
