This commit is also only appropriate for -qemu mips based boards, and should not be applied to any general branch. - -Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> ---- - arch/mips/oprofile/op_model_mipsxx.c | 2 ++ - 1 file changed, 2 insertions(+) - -diff --git a/arch/mips/oprofile/op_model_mipsxx.c b/arch/mips/oprofile/op_model_mipsxx.c -index 1ab4f15..16ecbf4 100644 ---- a/arch/mips/oprofile/op_model_mipsxx.c -+++ b/arch/mips/oprofile/op_model_mipsxx.c -@@ -419,7 +419,9 @@ static int __init mipsxx_init(void) - } - - save_perf_irq = perf_irq; -+#if 0 - perf_irq = mipsxx_perfcount_handler; -+#endif - - if ((cp0_perfcount_irq >= 0) && (cp0_compare_irq != cp0_perfcount_irq)) - return request_irq(cp0_perfcount_irq, mipsxx_perfcount_int, --- -1.7.10.4 - |
