Subject: [patch v1 0/3] arm: support pmu irq routed from CTI
Date: Wed, 2 Mar 2011 00:58:28 +0800 [thread overview]
Message-ID: <1298998711-8165-1-git-send-email-tom.leiming@gmail.com> (raw)
Hi,
This patches support pmu irq routed from CTI, such as implemented
on OMAP4:
- introduce some CTI helpers and registers' definition
- introduce platform_data to pmu driver, so perf irq handler
can handle irq correctly if it is routed from CTI
- configure CTI on OMAP4 so that perf can work on OMAP4
The patches have been tested Ok on Pandaboard, and 'perf' does work
after applying them.
v1:
- rebase the patch set against 2.6.38-rc6-next-20110301, fix
conflicts, which is pointed out by Will Deacon
