PCI/PM: Drain runtime-idle callbacks before driver removal

PCI/PM: Drain runtime-idle callbacks before driver removal

[ Upstream commit 9d5286d4e7f68beab450deddbb6a32edd5ecf4bf ]

A race condition between the .runtime_idle() callback and the .remove()
callback in the rtsx_pcr PCI driver leads to a kernel crash due to an
unhandled page fault [1].

The problem is that rtsx_pci_runtime_idle() is not expected to be running
after pm_runtime_get_sync() has been called, but the latter doesn't really
guarantee that. It only guarantees that the suspend and resume callbacks
will not be running when it returns.

However, if a .runtime_idle() callback is already running when
pm_runtime_get_sync() is called, the latter will notice that the runtime PM
status of the device is RPM_ACTIVE and it will return right away without
waiting for the former to complete. In fact, it cannot wait for
.runtime_idle() to complete because it may be called from that callback (it
arguably does not make much sense to do that, but it is not strictly
prohibited).

Thus in general, whoever is providing a .runtime_idle() callback needs
to protect it from running in parallel with whatever code runs after
pm_runtime_get_sync(). [Note that .runtime_idle() will not start after
pm_runtime_get_sync() has returned, but it may continue running then if it
has started earlier.]

One way to address that race condition is to call pm_runtime_barrier()
after pm_runtime_get_sync() (not before it, because a nonzero value of the
runtime PM usage counter is necessary to prevent runtime PM callbacks from
being invoked) to wait for the .runtime_idle() callback to complete should
it be running at that point. A suitable place for doing that is in
pci_device_remove() which calls pm_runtime_get_sync() before removing the
driver, so it may as well call pm_runtime_barrier() subsequently, which
will prevent the race in question from occurring, not just in the rtsx_pcr
driver, but in any PCI drivers providing .runtime_idle() callbacks.

PCI/PM: Mark devices disconnected if upstream PCIe link is down on resume

PCI/PM: Mark devices disconnected if upstream PCIe link is down on resume

Mark Blakeney reported that when suspending system with a Thunderbolt
dock connected and then unplugging the dock before resume (which is
pretty normal flow with laptops), resuming takes long time.

What happens is that the PCIe link from the root port to the PCIe switch
inside the Thunderbolt device does not train (as expected, the link is
unplugged):

pcieport 0000:00:07.2: restoring config space at offset 0x24 (was 0x3bf12001, writing 0x3bf12001)
pcieport 0000:00:07.0: waiting 100 ms for downstream link
pcieport 0000:01:00.0: not ready 1023ms after resume; giving up

However, at this point we still try to resume the devices below that
unplugged link:

pcieport 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
...
pcieport 0000:01:00.0: restoring config space at offset 0x38 (was 0xffffffff, writing 0x0)
...
pcieport 0000:02:02.0: waiting 100 ms for downstream link, after activation

And this is the link from PCIe switch downstream port to the xHCI on the
dock:

xhci_hcd 0000:03:00.0: not ready 65535ms after resume; giving up
xhci_hcd 0000:03:00.0: Unable to change power state from D3cold to D0, device inaccessible
xhci_hcd 0000:03:00.0: restoring config space at offset 0x3c (was 0xffffffff, writing 0x1ff)

This ends up slowing down the resume time considerably. For this reason
mark these devices as disconnected if the link above them did not train
properly.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Add locking to read/modify/write PCIe Capability Register accessors
for Link Control and Root Control
- Use pci_dev_id() when possible instead of manually composing ID
from dev->bus->number and dev->devfn

Resource management:
- Move prototypes for __weak sysfs resource files to linux/pci.h to
fix 'no previous prototype' warnings
- Make more I/O port accesses depend on HAS_IOPORT
- Use devm_platform_get_and_ioremap_resource() instead of open-coding
platform_get_resource() followed by devm_ioremap_resource()

Power management:
- Ensure devices are powered up while accessing VPD
- If device is powered-up, keep it that way while polling for PME
- Only read PCI_PM_CTRL register when available, to avoid reading the
wrong register and corrupting dev->current_state

Virtualization:
- Avoid Secondary Bus Reset on NVIDIA T4 GPUs

Error handling:
- Remove unused pci_disable_pcie_error_reporting()
- Unexport pci_enable_pcie_error_reporting(), used only by aer.c
- Unexport pcie_port_bus_type, used only by PCI core

VGA:
- Simplify and clean up typos in VGA arbiter

Apple PCIe controller driver:

process LINK_DOWN events
- Add suspend/resume support, including manual
PME_Turn_off/PME_TO_Ack handshake
- Save Link Capabilities during probe so they can be restored when
handling a link-up event, since the controller loses the Link Width

hibernate if MSI/MSI-X hasn't been enabled

NVIDIA Tegra194 PCIe controller driver:
- Revert 'PCI: tegra194: Enable support for 256 Byte payload' because
Linux doesn't know how to reduce MPS from to 256 to 128 bytes for
endpoints below a switch (because other devices below the switch
might already be operating), which leads to 'Malformed TLP' errors

Qualcomm PCIe controller driver:
- Add DT and driver support for interconnect bandwidth voting for

suspend/resume ops, and a controller callback to send PME_Turn_Off
