We replace the RTL9300 timer with a +Clock Event Timer (CEVT), which is VSMP aware and can be instantiated +as part of brining a VSMTP cpu up instead of the R4K CEVT source. +For this we place the RTL9300 CEVT timer in arch/mips/kernel +together with other MIPS CEVT timers, initialize the SoC IRQs +from a modified smp-mt.c and instantiate each timer as part +of the MIPS time setup in arch/mips/include/asm/time.h instead +of the R4K CEVT, similarly as is done by other MIPS CEVT timers. + +Submitted-by: Birger Koblitz <git@birger-koblitz.de> +--- + arch/mips/kernel/Makefile | 1 + + arch/mips/include/asm/time.h | 7 +++++++ + 2 files changed, 8 insertions(+) + --- a/arch/mips/kernel/Makefile +++ b/arch/mips/kernel/Makefile @@ -27,6 +27,7 @@ obj-$(CONFIG_CEVT_BCM1480) += cevt-bcm14 |
