PCI: Fix bridge_d3 update on device removal
Starting with v4.8, we allow a PCIe port to runtime suspend to D3hot if the
port itself and its children satisfy a number of conditions. Once a child
is removed, we recheck those conditions in case the removed device was
blocking the port from suspending.
The rechecking needs to happen *after* the device has been removed from the
bus it resides on. Otherwise when walking the port's subordinate bus in
pci_bridge_d3_update(), the device being removed would erroneously still be
taken into account.
However the device is removed from the bus_list in pci_destroy_dev() and we
currently recheck *before* that. Fix it.

thunderbolt: Fix resume quirk for Falcon Ridge 4C.
The quirk 'quirk_apple_wait_for_thunderbolt' did not fire on Falcon
Ridge 4C controllers with subdevice/subvendor set to zero. This lead
to lost pci devices on system resume.
Older thunderbolt controllers (pre Falcon Ridge) used the same device id
for bridges and for the controller. On Apple hardware the subvendor- &
subdevice-ids were set for the controller, but not for bridges. So that
is what was used to differentiate between the two. Starting with Falcon
Ridge bridges and controllers received different device ids.
Additionally on some MacBookPro models (but not all) the
subvendor/subdevice was zeroed.

cxl: use pcibios_free_controller_deferred() when removing vPHBs
When cxl removes a vPHB, it's possible that the pci_controller may be freed before all references to the devices on the vPHB have been released. This in turn causes an invalid memory access when the devices are eventually released, as pcibios_release_device() attempts to call the phb's release_device hook. In cxl_pci_vphb_remove(), remove the existing call to pcibios_free_controller(). Instead, use pcibios_free_controller_deferred() to free the pci_controller after all devices have been released. Export pci_set_host_bridge_release() so we can do this. Cc: stable@vger.kernel.org Signed-off-by: Andrew Donnellan <andrew.donnellan@au1.ibm.com> Reviewed-by: Matthew R.

PCI: Call pci_intx() when using legacy interrupts in pci_alloc_irq_vectors()
ahci currently insists on an explicit call to pci_intx() before falling back from MSI or MSI-X to legacy IRQs. As pci_intx() is a no-op if the command register already contains the right value it seems safe and useful to add this call to pci_alloc_irq_vectors() so that ahci can just use pci_alloc_irq_vectors().

PCI: Use positive flags in pci_alloc_irq_vectors()
Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of certain interrupt types, pass positive flags like PCI_IRQ_LEGACY, PCI_IRQ_MSI, etc., to specify the acceptable interrupt types. This is based on a number of pending driver conversions that just happend to be a whole more obvious to read this way, and given that we have no users in the tree yet it can still easily be done. I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting all interrupt types very simple.

genirq/msi: Make sure PCI MSIs are activated early
Bharat Kumar Gogada reported issues with the generic MSI code, where the
end-point ended up with garbage in its MSI configuration (both for the vector
and the message).
It turns out that the two MSI paths in the kernel are doing slightly different
things:
generic MSI: disable MSI -> allocate MSI -> enable MSI -> setup EP
PCI MSI: disable MSI -> allocate MSI -> setup EP -> enable MSI
And it turns out that end-points are allowed to latch the content of the MSI
configuration registers as soon as MSIs are enabled. In Bharat's case, the
end-point ends up using whatever was there already, which is not what you
want.
In order to make things converge, we introduce a new MSI domain flag
(MSI_FLAG_ACTIVATE_EARLY) that is unconditionally set for PCI/MSI. When set,
this flag forces the programming of the end-point as soon as the MSIs are
allocated.
A consequence of this is that we have an extra activate in irq_startup, but
that should be without much consequence.
tglx:
- Several people reported a VMWare regression with PCI/MSI-X passthrough. It
turns out that the patch also cures that issue.
- We need to have a look at the MSI disable interrupt path, where we write
the msg to all zeros without disabling MSI in the PCI device. Is that
correct?

ACPI / hotplug / PCI: Runtime resume bridges before bus rescans
If a PCI bridge (or PCIe port) that is runtime-suspended gets an ACPI hotplug notification, such as a bus check, it has to be resumed before re-scanning the devices below it, or those devices will not be accessible and will be treated as hot-removed. Make that happen and let the bridge suspend again after the bus below it has been re-scanned. This is a replacement for commit |

tree-wide: replace config_enabled() with IS_ENABLED()
The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

PCI: artpec: Add PCI_MSI_IRQ_DOMAIN dependency
The DesignWare PCIe driver requires MSI support, so we get a warning for the artpec6 glue driver if that is not enabled: warning: (PCIE_ARTPEC6) selects PCIE_DW which has unmet direct dependencies (PCI && PCI_MSI_IRQ_DOMAIN) Add the same dependency that all other such drivers have.

PCI: Add ACS quirk for Solarflare SFC9220
The Solarflare SFC9220 apparently lacks an ACS capability, but does not perform peer-to-peer between functions. Add a quirk so we know about this isolation. [bhelgaas: changelog] Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

The cpufreq changes that stand out somewhat are the governor interface rework and improvements related to the handling of frequency tables. Apart from those, there are fixes and new device/CPU IDs in drivers, cleanups and an improvement of the new schedutil governor. Next, there are some changes in the hibernation core, including a fix for a nasty problem related to the MONITOR/MWAIT usage by CPU offline during resume from hibernation, a few core improvements related to memory management during resume, a couple of additional debug features and cleanups. Finally, we have some fixes and cleanups in the devfreq subsystem, generic power domains framework improvements related to system suspend/resume, support for some new chips in intel_idle and in the power capping RAPL driver, a new version of the AnalyzeSuspend utility and some assorted fixes and cleanups.

PCI: tegra: Program PADS_REFCLK_CFG* registers with per-SoC values
The value that should be programmed into the PADS_REFCLK register varies per SoC. Fix the Tegra PCIe driver to program the correct values. Future SoCs will require different values in cfg0/1, so the two values are stored separately in the per-SoC data structures. For reference, the values are all documented in NV bug 1771116 comment 20. The ASIC team has validated all these values, except for the Tegra20 value which is simply left unchanged in this patch.

PCI: tegra: Stop setting pcibios_min_mem
pcibios_min_mem only exists on 32-bit ARM, so using it in pci-tegra.c prevents the driver from being used on other arches. In __pci_assign_resource(), we clip the available area based on PCIBIOS_MIN_MEM. On 32-bit ARM, this is pcibios_min_mem, with a default value of 0x01000000. For Tegra, we discover the space available for PCI resource allocation from the device tree, and the lowest address that will ever be available is 0x12000000 (on Tegra124). The Tegra windows are always higher than the default pcibios_min_mem, so the __pci_assign_resource() has no effect, so there's no need to adjust pcibios_min_mem here.
