2022-11-30xhci: disable U3 suspended ports in S4 hibernate poweroff_late stageMathias Nyman1-0/+52
Disable U3 suspended ports in hibernate S4 poweroff_late for systems with XHCI_RESET_TO_DEFAULT quirk, if wakeup is not enabled. This reduces the number of self-powered usb devices from surviving in U3 suspended state into next reboot. Bootloader/firmware on these systems can't handle usb ports in U3, and will timeout, causing extra delay during reboot/restore from S4. Add pci_poweroff_late() callback to struct usb_hcd to get this done at the correct stage in hibernate.

2022-11-30xhci: Apply XHCI_RESET_TO_DEFAULT quirk to ADL-NReka Norman1-1/+3
ADL-N systems have the same issue as ADL-P, where a large boot firmware delay is seen if USB ports are left in U3 at shutdown. So apply the XHCI_RESET_TO_DEFAULT quirk to ADL-N as well. This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset host back to default state at shutdown"). The issue it fixes is a ~20s boot time delay when booting from S5. It affects ADL-N devices, and ADL-N support was added starting from v5.16.

2022-11-09usb: xhci-pci: Set PROBE_PREFER_ASYNCHRONOUSBrian Norris1-3/+4
This driver often takes on the order of 10ms to start, but in some cases takes more than 100ms. It shouldn't have many cross-device dependencies to race with, nor racy access to shared state with other drivers, so this should be a relatively low risk change. This driver was pinpointed as part of a survey of top slowest initcalls (i.e., are built in, and probing synchronously) on a lab of ChromeOS systems.

2022-10-25xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later devicesMario Limonciello1-28/+4
For optimal power consumption of USB4 routers the XHCI PCIe endpoint used for tunneling must be in D3. Historically this is accomplished by a long list of PCIe IDs that correspond to these endpoints because the xhci_hcd driver will not default to allowing runtime PM for all devices. As both AMD and Intel have released new products with new XHCI controllers this list continues to grow. In reviewing the XHCI specification v1.2 on page 607 there is already a requirement that the PCI power management states D3hot and D3cold must be supported. In the quirk list, use this to indicate that runtime PM should be allowed on XHCI controllers. The following controllers are known to be xHC 1.2 and dropped explicitly: * AMD Yellow Carp * Intel Alder Lake * Intel Meteor Lake * Intel Raptor Lake [keep PCI ID for Alder Lake PCH for recently added quirk -Mathias] Cc: stable@vger.kernel.org Suggested-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/extensible-host-controler-interface-usb-xhci.pdf Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20221024142720.4122053-4-mathias.nyman@intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2022-10-25xhci: Add quirk to reset host back to default state at shutdownMathias Nyman1-0/+4
Systems based on Alder Lake P see significant boot time delay if boot firmware tries to control usb ports in unexpected link states. This is seen with self-powered usb devices that survive in U3 link suspended state over S5. A more generic solution to power off ports at shutdown was attempted in commit 83810f84ecf1 ("xhci: turn off port power in shutdown") but it caused regression. Add host specific XHCI_RESET_TO_DEFAULT quirk which will reset host and ports back to default state in shutdown.

2021-03-11usb: xhci: Fix ASMedia ASM1042A and ASM3242 DMA addressingForest Crossman1-2/+6
I've confirmed that both the ASMedia ASM1042A and ASM3242 have the same problem as the ASM1142 and ASM2142/ASM3142, where they lose some of the upper bits of 64-bit DMA addresses. As with the other chips, this can cause problems on systems where the upper bits matter, and adding the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.

2021-03-11usb: xhci: do not perform Soft Retry for some xHCI hostsStanislaw Gruszka1-0/+5
On some systems rt2800usb and mt7601u devices are unable to operate since commit f8f80be501aa ("xhci: Use soft retry to recover faster from transaction errors") Seems that some xHCI controllers can not perform Soft Retry correctly, affecting those devices. To avoid the problem add xhci->quirks flag that restore pre soft retry xhci behaviour for affected xHCI controllers. Currently those are AMD_PROMONTORYA_4 and AMD_PROMONTORYA_2, since it was confirmed by the users: on those xHCI hosts issue happen and is gone after disabling Soft Retry.

2020-02-10xhci: fix runtime pm enabling for quirky Intel hostsMathias Nyman1-3/+3
Intel hosts that need the XHCI_PME_STUCK_QUIRK flag should enable runtime pm by calling xhci_pme_acpi_rtd3_enable() before usb_hcd_pci_probe() calls pci_dev_run_wake(). Otherwise usage count for the device won't be decreased, and runtime suspend is prevented. usb_hcd_pci_probe() only decreases the usage count if device can generate run-time wake-up events, i.e. when pci_dev_run_wake() returns true. This issue was exposed by pci_dev_run_wake() change in commit 8feaec33b986 ("PCI / PM: Always check PME wakeup capability for runtime wakeup support") and should be backported to kernels with that change Cc: <stable@vger.kernel.org> # 4.13+ Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20200210134553.9144-4-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
