This is caused by the +c0_compare_int_usable() routine in cevt-r4k.c returning false which +causes the system to disable the timer and hang later. The false +return happens because the routine is using a series of four calls to +irq_disable_hazard() as a delay while it waits for the timer changes +to propagate to the cp0 cause register. On newer MIPS cores, like the 74K, +the series of irq_disable_hazard() calls turn into ehb instructions and +can take as little as a few clock ticks for all 4 instructions. This +is not enough of a delay, so the routine thinks the timer is not working. +This fix uses up to a max number of cycle counter ticks for the delay +and uses back_to_back_c0_hazard() instead of irq_disable_hazard() to +handle the hazard condition between cp0 writes and cp0 reads. + +Signed-off-by: Al Cooper <alcooperx@gmail.com> + +--- +arch/mips/kernel/cevt-r4k.c | 38 +++++++++++++++++++------------------- + 1 files changed, 19 insertions(+), 19 deletions(-) + +--- a/arch/mips/kernel/cevt-r4k.c ++++ b/arch/mips/kernel/cevt-r4k.c +@@ -103,19 +103,10 @@ static int c0_compare_int_pending(void) + + /* + * Compare interrupt can be routed and latched outside the core, +- * so a single execution hazard barrier may not be enough to give +- * it time to clear as seen in the Cause register. 4 time the +- * pipeline depth seems reasonably conservative, and empirically +- * works better in configurations with high CPU/bus clock ratios. ++ * so wait up to worst case number of cycle counter ticks for timer interrupt ++ * changes to propagate to the cause register. + */ +- +-#define compare_change_hazard() \ +- do { \ +- irq_disable_hazard(); \ +- irq_disable_hazard(); \ +- irq_disable_hazard(); \ +- irq_disable_hazard(); \ +- } while (0) ++#define COMPARE_INT_SEEN_TICKS 50 + + int c0_compare_int_usable(void) + { +@@ -126,8 +117,12 @@ int c0_compare_int_usable(void) + * IP7 already pending?
