Subject: [PATCH v2] ARC: Enable PERF_EVENTS in nSIM driven platforms
Date: Mon, 31 Oct 2016 15:59:11 +0300 [thread overview]
Message-ID: <1477918751-28058-1-git-send-email-abrodkin@synopsys.com> (raw)
Now when we have properly working performance counters in nSIM
even with interrupt support (fix should be a part of upcoming
nSIM engineering build 2016.12-005) we may enable perf support
by default for all platforms that use nSIM for ARC cores simulation.
Note 1: PCT node was missing for some reason in nsimosci.dts
while all other nSIM-related .dts files already had
PCT node for quite some time, so adding it now.
Note 2: All defconfigs were regenerated with "make savedefconfig"
which led to some clean-ups in nsimosci_hs_smp_defconfig:
CONFIG_FRAMEBUFFER_CONSOLE=y was removed because it is
automatically selected now by DRM.
