[Linux-kernel-mentees] [PATCH 00/11] PCI: Move symbols to drivers/pci/pci.h

[skunberg.kelsey]

Move symbols defined in include/linux/pci.h that are only used in
drivers/pci/ to drivers/pci/pci.h.

Symbols only used in drivers/pci/ do not need to be visible to the rest of
the kernel.

Kelsey Skunberg (11):
  PCI: Move #define PCI_PM_* lines to drivers/pci/pci.h
  PCI: Move PME declarations to drivers/pci/pci.h
  PCI: Move *_host_bridge_device() declarations to drivers/pci.pci.h
  PCI: Move PCI Virtual Channel declarations to drivers/pci/pci.h
  PCI: Move pci_hotplug_*_size declarations to drivers/pci/pci.h
  PCI: Move pci_bus_* declarations to drivers/pci/pci.h
  PCI: Move pcie_update_link_speed() to drivers/pci/pci.h
  PCI: Move pci_ats_init() to drivers/pci/pci.h
  PCI: Move ECRC declarations to drivers/pci/pci.h
  PCI: Move PTM declaration to drivers/pci/pci.h
  PCI: Move pci_*_node() declarations to drivers/pci/pci.h

[Linux-kernel-mentees] [PATCH 04/11] PCI: Move PCI Virtual Channel declarations to drivers/pci/pci.h

[Kelsey Skunberg]

PCI Virtual Channel declarations are only called within drivers/pci/.
Since declarations do not need to be visible to the rest of the kernel,
move to drivers/pci/pci.h.

Hi Kelsey,

I didn't get these applied before v5.3-rc1, so now they don't apply
cleanly.  Would you mind refreshing them and posting a v2 that does
apply to my "master" branch (v5.3-rc1)?

[Linux-kernel-mentees] [PATCH v2 00/11] Hide PCI symbols that don't need to be global

[skunberg.kelsey]

The include/linux/pci.h header file defines several symbols that are used
only in drivers/pci/. These symbols do not need to be visible to the rest

drivers/pci/pci.h.

Changes in v2:
        - Built patches to work with v5.3-rc1
        - Changed line lengths on commit logs to stay below 80 characters
	- Changed cover-letter log to better explain patch series

Unrelated to *this* patch, but while reviewing, I noticed this a few
lines below:

  static inline void pci_wakeup_event(struct pci_dev *dev)
  {
    /* Wait 100 ms before the system can be put into a sleep state. */
    pm_wakeup_event(&dev->dev, 100);
  }

I'm curious about what this 100ms is and whether it's related to
something in the PCIe spec.  E.g., is this another way of writing
PCI_PM_D3COLD_WAIT?

This constant was added to drivers/pci/pci.c as PCI_WAKEUP_COOLDOWN by
c125e96f0444 ("PM: Make it possible to avoid races between wakeup and
system sleep") and then moved to drivers/pci/pci.h and the name
removed by b6e335aeeb11 ("PCI/PM: Use pm_wakeup_event() directly for
reporting wakeup events").

[Linux-kernel-mentees] [PATCH v2 04/11] PCI: Move PCI Virtual Channel declarations to drivers/pci/pci.h

[Kelsey Skunberg]

PCI Virtual Channel declarations are only called within drivers/pci/.
Since declarations do not need to be visible to the rest of the kernel,
move to drivers/pci/pci.h.

[Linux-kernel-mentees] [PATCH v2 08/11] PCI: Move pci_ats_init() to drivers/pci/pci.h

[Kelsey Skunberg]

pci_ats_init() is only called with drivers/pci/. Since declarations do not
need to be visible to the rest of the kernel, move to drivers/pci/pci.h.
