Convert sis-agp from legacy PCI power management to the generic power management framework. Previously, sis-agp used legacy PCI power management, and agp_sis_suspend() and agp_sis_resume() were responsible for both device-specific things and generic PCI things: agp_sis_suspend pci_save_state(pdev) <-- generic PCI pci_set_power_state(pdev, pci_choose_state(pdev, state)) <-- generic PCI agp_sis_resume pci_set_power_state(pdev, PCI_D0) <-- generic PCI pci_restore_state(pdev) <-- generic PCI sis_driver.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_sis_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_sis_resume # dev->driver->pm->resume sis_driver.configure() <-- device-specific [bhelgaas: commit log] Link: https://lore.kernel.org/r/20211208193305.147072-3-helgaas@kernel.org Signed-off-by: Vaibhav Gupta <vaibhavgupta40@gmail.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Dave Airlie <airlied@redhat.com> |
