Running a UP kernel on a bcm1480 board, I get nonsensical timing results, like this: release@unknown:~/tmp$ time ./a.out real 0m22.906s user 0m45.792s sys 0m0.010s According to my watch, this program took 23 seconds to run, so the real time clock is OK. It is process accounting that is broken. I tracked this down to a problem with the function bcm1480_timer_interrupt in the file sibyte/bcm1480/time.c. This function calls ll_timer_interrupt for cpu0, and ll_local_timer_interrupt for all cpus. However, both of these functions do process accounting. Thus processes running on cpu0 end up with doubled times. This is very obvious in a UP kernel where all processes run on cpu0. The correct way to do this is to only call ll_local_timer interrupt if this is not cpu0. This can be seen in the mips-board/generic/time.c file, and also in the sibyte/sb1250/time.c file, both of which handle this correctly. I fixed the bcm1480/time.c file by copying over the correct code from the sb1250/time.c file. With this fix, I now get sensible results. release@unknown:~/tmp$ time ./a.out real 0m22.903s user 0m22.894s sys 0m0.006s Signed-off-by: Ralf Baechle --- arch/mips/sibyte/bcm1480/time.c | 17 +++++++++-------- 1 file changed, 9 insertions(+), 8 deletions(-) diff --git a/arch/mips/sibyte/bcm1480/time.c b/arch/mips/sibyte/bcm1480/time.c index e545752695a1..efaf83efd2e4 100644 --- a/arch/mips/sibyte/bcm1480/time.c +++ b/arch/mips/sibyte/bcm1480/time.c @@ -110,17 +110,18 @@ void bcm1480_timer_interrupt(struct pt_regs *regs) __raw_writeq(M_SCD_TIMER_ENABLE|M_SCD_TIMER_MODE_CONTINUOUS, IOADDR(A_SCD_TIMER_REGISTER(cpu, R_SCD_TIMER_CFG))); - /* - * CPU 0 handles the global timer interrupt job - */ if (cpu == 0) { + /* + * CPU 0 handles the global timer interrupt job + */ ll_timer_interrupt(irq, regs); } - - /* - * every CPU should do profiling and process accouting - */ - ll_local_timer_interrupt(irq, regs); + else { + /* + * other CPUs should just do profiling and process accounting + */ + ll_local_timer_interrupt(irq, regs); + } } /* From 0307e8d024dffc00743fb54b9afa920a346f1adb Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Sun, 11 Jun 2006 23:25:43 +0900 Subject: [PATCH 08/51] [MIPS] Fix futex_atomic_op_inuser.

Most architecture definitions of kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM on i386 and MIPS even as 0; the 0-definition will result in kmem_ptr_validate always failing which in turn will cause d_validate to always fail. d_validate's only two users are smbfs and ncpfs, so the 0 definition ended breaking those ...
