Subject: [PATCH] PCI: Update platform power state when updating PCI state
|
|
|
|
|
Date: Mon, 9 Nov 2020 14:23:00 +0100
|
|
|
|
|
Subject: [PATCH] PCI: Run platform power transition on initial D0 entry
|
|
|
|
|
|
|
|
|
|
On some devices and platforms, the initial platform power state is not
|
|
|
|
|
in sync with the power state of the PCI device.
|
|
|
|
|
|
|
|
|
|
Specifically, on the Surface Book 2 and 3, some ACPI power regions that
|
|
|
|
|
should be "on" for the D0 state (and others) are initialized as "off" in
|
|
|
|
|
ACPI, whereas the PCI device is in D0. As the state is updated in
|
|
|
|
|
pci_enable_device_flags() without ensuring that the platform state is
|
|
|
|
|
also updated, the power resource will never be properly turned on.
|
|
|
|
|
Instead, it lives in a sort of on-but-marked-as-off zombie-state, which
|
|
|
|
|
confuses things down the line when attempting to transition the device
|
|
|
|
|
into D3cold: As the resource is already marked as off, it won't be
|
|
|
|
|
turned off and the device does not fully enter D3cold, causing increased
|
|
|
|
|
power consumption during (runtime-)suspend.
|
|
|
|
|
pci_enable_device_flags() updates the state of a PCI device by reading
|
|
|
|
|
from the the PCI_PM_CTRL register. This may change the stored power
|
|
|
|
|
state of the device without running the appropriate platform power
|
|
|
|
|
transition.
|
|
|
|
|
|
|
|
|
|
Ensuring that the platform power state is in sync with the PCI power
|
|
|
|
|
state when updating the latter guarantees that all required ACPI power
|
|
|
|
|
regions are powered on/off in accordance with the requirements
|
|
|
|
|
(specified in the ACPI _PRn fields) for the current PCI power state.
|
|
|
|
|
Due to the stored power-state being changed, the later call to
|
|
|
|
|
pci_set_power_state(..., PCI_D0) in do_pci_enable_device() can evaluate
|
|
|
|
|
to a no-op if the stored state has been changed to D0 via that. This
|
|
|
|
|
will then prevent the appropriate platform power transition to be run,
|
|
|
|
|
which can on some devices and platforms lead to platform and PCI power
|
|
|
|
|
state being entirely different, i.e. out-of-sync. On ACPI platforms,
|
|
|
|
|
this can lead to power resources not being turned on, even though they
|
|
|
|
|
are marked as required for D0.
|
|
|
|
|
|
|
|
|
|
Specifically, on the Microsoft Surface Book 2 and 3, some ACPI power
|
|
|
|
|
regions that should be "on" for the D0 state (and others) are
|
|
|
|
|
initialized as "off" in ACPI, whereas the PCI device is in D0. As the
|
|
|
|
|
state is updated in pci_enable_device_flags() without ensuring that the
|
|
|
|
|
platform state is also updated, the power resource will never be
|
|
|
|
|
properly turned on. Instead, it lives in a sort of on-but-marked-as-off
|
|
|
|
|
zombie-state, which confuses things down the line when attempting to
|
|
|
|
|
transition the device into D3cold: As the resource is already marked as
|
|
|
|
|
off, it won't be turned off and the device does not fully enter D3cold,
|
|
|
|
|
causing increased power consumption during (runtime-)suspend.
|
|
|
|
|
|
|
|
|
|
By replacing pci_set_power_state() in do_pci_enable_device() with
|
|
|
|
|
pci_power_up(), we can force pci_platform_power_transition() to be
|
|
|
|
|
called, which will then check if the platform power state needs updating
|
|
|
|
|
and appropriate actions need to be taken.
