Subject: [PATCH v2 0/8] agp: Convert to generic power management

From: Bjorn Helgaas <[email protected]>

Vaibhav converted several AGP drivers from legacy PCI power management to
generic power management [1]. This series converts the rest of them.

v1 posted at [2].

Changes from v1 to v2:
- Convert from SIMPLE_DEV_PM_OPS() (which is deprecated) to
DEFINE_SIMPLE_DEV_PM_OPS() and remove __maybe_unused annotations.

Subject: [PATCH v2 6/8] agp/amd64: Update to DEFINE_SIMPLE_DEV_PM_OPS()

From: Bjorn Helgaas <[email protected]>

As of 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old
ones"), SIMPLE_DEV_PM_OPS() is deprecated in favor of
DEFINE_SIMPLE_DEV_PM_OPS(), which has the advantage that the PM callbacks
don't need to be wrapped with #ifdef CONFIG_PM or tagged with
__maybe_unused.

Convert to DEFINE_SIMPLE_DEV_PM_OPS(). No functional change intended.

Subject: [PATCH v2 4/8] agp/ati: Convert to generic power management

From: Bjorn Helgaas <[email protected]>

Convert agpgart-ati from legacy PCI power management to the generic power
management framework.

Previously agpgart-ati used legacy PCI power management, and
agp_ati_suspend() and agp_ati_resume() were responsible for both
device-specific things and generic PCI things like saving and restoring
config space and managing power state:

agp_ati_suspend
pci_save_state <-- generic PCI
pci_set_power_state(PCI_D3hot) <-- generic PCI

agp_ati_resume
pci_set_power_state(PCI_D0) <-- generic PCI
pci_restore_state <-- generic PCI
ati_configure <-- device-specific

With generic power management, the PCI bus PM methods do the generic PCI
things, and the driver needs only the device-specific part, i.e.,

suspend_devices_and_enter
dpm_suspend_start(PMSG_SUSPEND)
pci_pm_suspend # PCI bus .suspend() method
agp_ati_suspend <-- not needed at all; removed
suspend_enter
dpm_suspend_noirq(PMSG_SUSPEND)
pci_pm_suspend_noirq # PCI bus .suspend_noirq() method
pci_save_state <-- generic PCI
pci_prepare_to_sleep <-- generic PCI
pci_set_power_state
...
dpm_resume_end(PMSG_RESUME)
pci_pm_resume # PCI bus .resume() method
pci_restore_standard_config
pci_set_power_state(PCI_D0) <-- generic PCI
pci_restore_state <-- generic PCI
agp_ati_resume # driver->pm->resume
ati_configure <-- device-specific

Based on 0aeddbd0cb07 ("via-agp: convert to generic power management") by
Vaibhav Gupta <[email protected]>.

Do you want to merge through the PCI tree?
