* | ARM: 5901/2: arm/oprofile: reserve the PMU when starting | Jamie Iles | 2010-02-12 |
| | | | | | | | | | | Make sure that we have access to the performance counters and that they aren't being used by perf events or anything else.

* | ARM: 5849/1: ARMv7: fix Oprofile events count | Jean PIHET | 2009-12-22 |
| | | | | | | | | | | | | | | On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs and so to decrease the risk of errata #628216 from appearing. The effect of setting the PMNC_D bit is that the CCNT counter is divided by 64, making the program counter events count inaccurate. The new OMAP3 r4 cores should have that errata fixed. The PMNC_D bit should not be set, this patch fixes it. Signed-off-by: Jean Pihet <jpihet@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> | ||
