Subject: [PATCH 0/3] arm: support pmu irq routed from CTI
Date: Tue, 1 Mar 2011 21:17:11 +0800 [thread overview]
Message-ID: <1298985434-3009-1-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.
