* [POWERPC] Fix build of modular drivers/macintosh/apm_emu.cGuido Guenther2008-03-131-1/+1
| | | | | | | | | | | | | | | | Currently, if drivers/macintosh/apm_emu is a module and the config doesn't have CONFIG_SUSPEND we get: ERROR: "pmu_batteries" [drivers/macintosh/apm_emu.ko] undefined! ERROR: "pmu_battery_count" [drivers/macintosh/apm_emu.ko] undefined! ERROR: "pmu_power_flags" [drivers/macintosh/apm_emu.ko] undefined! on PPC32. The variables aren't wrapped in '#if defined(CONFIG_SUSPEND)' so we probably shouldn't wrap the exports either. This removes the CONFIG_SUSPEND part of the export, which fixes compilation on ppc32.

* [POWERPC] Fix sleep on some powerbooksBenjamin Herrenschmidt2008-03-131-2/+3
| | | | | | | | | | | | | The PMU backlight code would kick in during sleep/resume even on machines that use a different backlight method. This breaks sleep on some PowerBooks. This fixes it by adding a flag to indicate whether the backlight is controlled by the PMU, and testing that before trying to use the PMU to turn off the backlight during sleep.

* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

* [POWERPC] Disable G5 NAP mode during SMU commands on U3Benjamin Herrenschmidt2008-02-081-1/+24
| | | | | | | | | | | | | | | | | | | It appears that with the U3 northbridge, if the processor is in NAP mode the whole time while waiting for an SMU command to complete, then the SMU will fail. It could be related to the weird backward mechanism the SMU uses to get to system memory via i2c to the northbridge that doesn't operate properly when the said bridge is in napping along with the CPU. That is on U3 at least, U4 doesn't seem to be affected. This didn't show before NO_HZ as the timer wakeup was enough to make it work it seems, but that is no longer the case. This fixes it by disabling NAP mode on those machines while an SMU command is in flight.

* | [POWERPC] Fix for via-pmu based backlight controlBenjamin Herrenschmidt2007-12-212-34/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a few issues with via-pmu based backlight control. First, it fixes a sign problem with the setup of the backlight curve since the `range' value there -can- (and will) go negative. Then, it reworks the interaction between this and the via-pmu sleep code to properly restore backlight on wakeup from sleep.

* | [POWERPC] Implement arch disable/enable irq hooks.Scott Wood2007-12-211-42/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These hooks ensure that a decrementer interrupt is not pending when suspending; otherwise, problems may occur on 6xx/7xx/7xxx-based systems (except for powermacs, which use a separate suspend path). For example, with deep sleep on the 831x, a pending decrementer will cause a system freeze because the SoC thinks the decrementer interrupt would have woken the system, but the core must have interrupts disabled due to the setup required for deep sleep. Changed via-pmu.c to use the new ppc_md hooks, and made the arch_* functions call the generic_* functions unconditionally. -- paulus Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds platform_suspend_ops for PMU based machines, directly in the PMU driver. This allows suspending via /sys/power/state on powerbooks. The patch also replaces the PMU ioctl with a simple call to pm_suspend(PM_SUSPEND_MEM). Additionally, it cleans up some debug code.

* | [POWERPC] Fix sleep on powerbook 3400Paul Mackerras2007-12-191-136/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

I thought about making it use kthread_stop() instead of the `state' variable and the `ctrl_complete' completion, but that isn't simple and will require changing the way that `state' is used.

* | [POWERPC] Convert adb.c to use kthread API and not spin on ADB requestsPaul Mackerras2007-12-191-57/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts adb.c to use the kthread API. It also changes adb_request so that if the ADBREQ_SYNC flag is specified, we now sleep waiting for the request to finish using an on-stack completion rather than spinning. To implement this, we now require that if the ADBREQ_SYNC flag is set, the `done' parameter must be NULL. All of the existing callers of adb_request that pass ADBREQ_SYNC appear to be in process context and have done == NULL. Doing this allows us to get rid of an awful hack in adb_request() where we used to test whether the request was coming from the adb probe task and use a completion if it was, and otherwise spin. This also gets rid of a static request block that was used if the req parameter to adb_request was NULL. None of the callers do that any more, so the static request block is no longer necessary.
