2021-06-03PCI: microchip: Make the struct event_descs staticKrzysztof Wilczyński1-1/+1
The struct event_descs does not have any users outside the pcie-microchip-host.c file, and has no previous declaration, thus it can be made static. This resolves the following sparse warning: drivers/pci/controller/pcie-microchip-host.c:352:3: warning: symbol 'event_descs' was not declared. Should it be static?

2021-05-27PCI: Print a debug message on PCI device releaseNiklas Schnelle1-0/+1
Commit 62795041418d ("PCI: enhance physical slot debug information") added a debug print on releasing the PCI slot and another message on destroying it. There is however no debug print on releasing the PCI device structure itself and even with closely looking at the kernel log during hotplug testing, I overlooked several missing pci_dev_put() calls for way too long. Add a debug print in pci_release_dev() making it much easier to spot when the PCI device structure is not released when it is supposed to be.

2021-05-27PCI: Add sysfs "removable" attributeRajat Jain1-0/+22
A PCI device is "external_facing" if it's a Root Port with the ACPI "ExternalFacingPort" property or if it has the DT "external-facing" property. We consider everything downstream from such a device to be removable by user. We're mainly concerned with consumer platforms with user accessible Thunderbolt ports that are vulnerable to DMA attacks, and we expect those ports to be identified by firmware as "ExternalFacingPort". Devices in traditional hotplug slots can technically be removed, but the expectation is that unless the port is marked with "ExternalFacingPort", such devices are less accessible to user / may not be removed by end user, and thus not exposed as "removable" to userspace. This can be used to implement userspace policies tailored for user removable devices. Eg usage: https://chromium-review.googlesource.com/c/chromiumos/platform2/+/2591812 https://chromium-review.googlesource.com/c/chromiumos/platform2/+/2795038 (code uses such an attribute to remove external PCI devices or disable features on them as needed by the policy desired) Acked-by: Bjorn Helgaas <[email protected]> Signed-off-by: Rajat Jain <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2021-05-25PCI/MSI: Fix MSIs for generic hosts that use device-tree's "msi-map"Jean-Philippe Brucker2-1/+9
Since commit 9ec37efb8783 ("PCI/MSI: Make pci_host_common_probe() declare its reliance on MSI domains"), platforms that rely on the "msi-map" device-tree property don't get MSIs anymore. On the Arm Fast Model for example [1], the host bridge doesn't have a "msi-parent" property since it doesn't itself generate MSIs, and so doesn't get a MSI domain. It has an "msi-map" property instead to describe MSI controllers of child devices. As a result, due to the new msi_domain check in pci_register_host_bridge(), the whole bus gets PCI_BUS_FLAGS_NO_MSI. Check whether the root complex has an "msi-map" property before giving up on MSIs.

2021-05-24PCI: Work around Huawei Intelligent NIC VF FLR erratumChiqijun1-0/+65
pcie_flr() starts a Function Level Reset (FLR), waits 100ms (the maximum time allowed for FLR completion by PCIe r5.0, sec 6.6.2), and waits for the FLR to complete. It assumes the FLR is complete when a config read returns valid data. When we do an FLR on several Huawei Intelligent NIC VFs at the same time, firmware on the NIC processes them serially. The VF may respond to config reads before the firmware has completed its reset processing. If we bind a driver to the VF (e.g., by assigning the VF to a virtual machine) in the interval between the successful config read and completion of the firmware reset processing, the NIC VF driver may fail to load. Prevent this driver failure by waiting for the NIC firmware to complete its reset processing. Not all NIC firmware supports this feature.

2021-05-24PCI: Add pci_reset_bus_function() Secondary Bus Reset interfaceRaphael Norwitz1-8/+12
pci_parent_bus_reset() resets a device by performing a Secondary Bus Reset on a PCI-to-PCI bridge leading to the device. pci_dev_reset_slot_function() does the same, except that it uses a hotplug driver to keep the reset from looking like a hot-remove followed by a hot-add. Add a pci_reset_bus_function() wrapper, which attempts the hotplug driver slot reset and falls back to the parent bus reset if that fails. This provides a single interface for performing a Secondary Bus Reset.

2021-05-03PCI: brcmstb: Use reset/rearm instead of deassert/assertJim Quinlan1-6/+13
The Broadcom STB PCIe RC uses a reset control "rescal" for certain chips. The "rescal" implements a "pulse reset" so using assert/deassert is wrong for this device. Instead, we use reset/rearm. We need to use rearm so that we can reset it after a suspend/resume cycle; w/o using "rearm", the "rescal" device will only ever fire once. Of course for suspend/resume to work we also need to put the reset/rearm calls in the suspend and resume routines.

2021-04-30PCI: Allow VPD access for QLogic ISP2722Arun Easi1-1/+0
0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") disabled access to VPD of the ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter because reading past the end of the VPD caused NMIs. 104daa71b396 ("PCI: Determine actual VPD size on first access") limits reads to the actual size of VPD, which should prevent these NMIs. 104daa71b396 was merged *before* 0d5370d1d852, but we think the testing that prompted 0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") was done with a kernel that lacked 104daa71b396. See [1, 2]. Remove the quirk added by 0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") so customers can read the HBA VPD.

2021-04-30PCI/VPD: Make missing VPD message less alarmingHeiner Kallweit1-2/+6
Realtek RTL8169/8168/8125 NIC families indicate VPD capability and an optional VPD EEPROM can be connected via I2C/SPI. However I haven't seen any card or system with such a VPD EEPROM yet. The missing EEPROM causes the following warning whenever e.g. lscpi -vv is executed. invalid short VPD tag 00 at offset 01 The warning confuses users, and I think we should handle the situation more gently. Therefore, if first VPD byte is read as 0x00, assume a missing optional VPD PROM and replace the warning with a more descriptive message at info level.

24a1720a0841 ("cxgb4: collect serial config version from register") removed the only usage of pci_set_vpd_size(). If a device needs to override the auto-detected VPD size, then this can be done with a PCI quirk, as is done for Chelsio devices. There's no need to allow drivers to change the VPD size. Remove pci_set_vpd_size().

With zpci_configure_device() now always called on a device that has already been configured on the platform level its name has become misleading. Rename it to zpci_scan_configured_device() to signify that the function now only handles the correct scanning of a newly configured PCI function taking care of the special handling necessary for function 0 and functions parked waiting for a PCI bus that can't be created without first seeing function 0.
