* [MIPS] Cleanup memory managment initialization.Ralf Baechle2006-06-19
| | | | | | | | | | Historically plat_mem_setup did the entire platform initialization. This was rather impractical because it meant plat_mem_setup had to get away without any kind of memory allocator. To keep old code from breaking plat_setup was just renamed to plat_setup and a second platform initialization hook for anything else was introduced. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [PATCH] Fix BCM1480 doubled process accounting times.[MIPS] James E Wilson2006-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <ralf@linux-mips.org>

* [MIPS] Fix deadlock on MP with cache aliases.Ralf Baechle2006-05-31
| | | | | | | | | | | | | A proper fix would involve introducing the notion of shared caches but at this stage of 2.6.17 that's going to be too intrusive and not needed for current hardware; aside I think some discussion will be needed. So for now on the affected SMP configurations which happen to suffer from cache aliases we make use of the fact that a single cache will be shared by all processors. This solves the deadlock issue and will improve performance by getting rid of the smp_call_function overhead. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
