Sleep on the powerbook 3400 has been broken since the change that made powerbook_sleep_3400 call pmac_suspend_devices(), which disables interrupts. There are a couple of loops in powerbook_sleep_3400 that depend on interrupts being enabled, and in fact it has to have interrupts enabled at the point of going to sleep since it is an interrupt from the PMU that wakes it up. This fixes it by using pmu_wait_complete() instead of a spinloop, and by explicitly enabling interrupts before putting the CPU into sleep mode (which is OK since all interrupts except the PMU interrupt have been disabled at the interrupt controller by this stage). This changes the logic so that it keeps putting the CPU into sleep mode until the completion of the interrupt transaction from the PMU that signals the end of sleep. Also, we now call pmu_unlock() before sleep so that the via_pmu_interrupt() code can process the interrupt event from the PMU properly. Now that generic code saves and restores PCI state, it is no longer necessary to do that here. Thus pbook_pci_save/restore and related functions are no longer necessary, so this removes them. Lastly, this moves the ioremap of the memory controller to init code rather than doing it on every sleep/wakeup cycle. Signed-off-by: Paul Mackerras <paulus@samba.org> |
