* [MIPS] Make timer interrupt frequency configurable from kconfig.Atsushi Nemoto2006-06-1950-1/+510
| | | | | | | | | | Make HZ configurable. DECSTATION can select 128/256/1024 HZ, JAZZ can only select 100 HZ, others can select 100/128/250/256/1000/1024 HZ if not explicitly specified). Also remove all mach-xxx/param.h files and update all defconfigs according to current HZ value. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Cleanup memory managment initialization.Ralf Baechle2006-06-1933-45/+75
| | | | | | | | | | 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 Wilson2006-06-191-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Matt Reimer There is a subtle bug in the GPIO interrupt status register handling in arch/arm/mach-imx/irq.c:imx_gpio_ack_irq(). The documentation states that a 1 should be written to the relevant bit to acknowledge a GPIO interrupt, but that is not what the code does. The problem is that the |= writes back 1s for all the *other* interrupts represented in the register, so interrupts could get lost. For example, if interrupts are pending for GPIO B10 and B12, ISR_B would have the value 0x00001400. Then when the interrupt code handles GPIO B10, it eventually calls imx_gpio_ack_irq(IRQ_GPIOB(10)), which effectively does this: ISR_B |= 1 << 10; with the result that (0x00001400 | 0x00000400) is written, clearing the interrupt status bits for *both* GPIO B10 and B12. The fix is to write 1s only for the interrupts we want to clear. The same problem seems to be occurring in the DMA code; this patch does not address those issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing the genirq code on ARM, a condition was found whereby the Neponset IRQ handler was being re-entered, causing the system to deadlock. Under the ARM IRQ code, this would not have been a visible problem because the "simple" IRQ handling had no re-entrancy protection. Resolve this by acknowledging the parent interrupt after we mask it when we are going to handle one of our "special" level-based sources (from ethernet or USAR chip.)
