2022-11-08usb: phy: phy-gpio-vbus-usb: Add device tree probingLinus Walleij2-1/+17
Make it possible to probe the GPIO VBUS detection driver from the device tree compatible for GPIO USB B connectors. Since this driver is using the "gpio-usb-b-connector" compatible, it is important to discern it from the role switch connector driver (which does not provide a phy), so we add some Kconfig text and depend on !USB_CONN_GPIO.

2022-11-03USB: core: Change configuration warnings to noticesAlan Stern1-41/+41
It has been pointed out that the kernel log messages warning about problems in USB configuration and related descriptors are vexing for users. The warning log level has a fairly high priority, but the user can do nothing to fix the underlying errors in the device's firmware. To reduce the amount of useless information produced by tools that filter high-priority log messages, we can change these warnings to notices, i.e., change dev_warn() to dev_notice(). The same holds for a few messages that currently use dev_err(): Unless they indicate a failure that might make a device unusable (such as inability to transfer a config descriptor), change them to dev_notice() also.

2022-10-26usb: dwc3: gadget: Don't set IMI for no_interruptThinh Nguyen1-2/+2
The gadget driver may have a certain expectation of how the request completion flow should be from to its configuration. Make sure the controller driver respect that. That is, don't set IMI (Interrupt on Missed Isoc) when usb_request->no_interrupt is set. Also, the driver should only set IMI to the last TRB of a chain.

2022-10-26usb: dwc3: gadget: Stop processing more requests on IMIThinh Nguyen1-0/+4
When servicing a transfer completion event, the dwc3 driver will reclaim TRBs of started requests up to the request associated with the interrupt event. Currently we don't check for interrupt due to missed isoc, and the driver may attempt to reclaim TRBs beyond the associated event. This causes invalid memory access when the hardware still owns the TRB. If there's a missed isoc TRB with IMI (interrupt on missed isoc), make sure to stop servicing further. Note that only the last TRB of chained TRBs has its status updated with missed isoc.

2022-10-25xhci: Remove device endpoints from bandwidth list when freeing the deviceMathias Nyman1-8/+12
Endpoints are normally deleted from the bandwidth list when they are dropped, before the virt device is freed. If xHC host is dying or being removed then the endpoints aren't dropped cleanly due to functions returning early to avoid interacting with a non-accessible host controller. So check and delete endpoints that are still on the bandwidth list when freeing the virt device. Solves a list_del corruption kernel crash when unbinding xhci-pci, caused by xhci_mem_cleanup() when it later tried to delete already freed endpoints from the bandwidth list. This only affects hosts that use software bandwidth checking, which currenty is only the xHC in intel Panther Point PCH (Ivy Bridge) Cc: [email protected] Reported-by: Marek Marczykowski-Górecki <[email protected]> Tested-by: Marek Marczykowski-Górecki <[email protected]> Signed-off-by: Mathias Nyman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
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: [email protected] Suggested-by: Mathias Nyman <[email protected]> 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 <[email protected]> Reviewed-by: Mika Westerberg <[email protected]> Signed-off-by: Mathias Nyman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2022-10-25xhci: Add quirk to reset host back to default state at shutdownMathias Nyman3-2/+13
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.

Since commit fc274c1e9973 ("USB: gadget: Add a new bus for gadgets"), the gadget devices are proper driver core devices, which caused each device to request pinmux settings: aspeed_vhub 1e6a0000.usb-vhub: Initialized virtual hub in USB2 mode aspeed-g5-pinctrl 1e6e2080.pinctrl: pin A7 already requested by 1e6a0000.usb-vhub; cannot claim for gadget.0 aspeed-g5-pinctrl 1e6e2080.pinctrl: pin-232 (gadget.0) status -22 aspeed-g5-pinctrl 1e6e2080.pinctrl: could not request pin 232 (A7) from group USB2AD on device aspeed-g5-pinctrl g_mass_storage gadget.0: Error applying setting, reverse things back The vhub driver has already claimed the pins, so prevent the gadgets from requesting them too by setting the magic of_node_reused flag. This causes the driver core to skip the mux request.

2022-10-22usb: gadget: uvc: fix sg handling during video encodeJeff Vanhoof1-2/+2
In uvc_video_encode_isoc_sg, the uvc_request's sg list is incorrectly being populated leading to corrupt video being received by the remote end. When building the sg list the usage of buf->sg's 'dma_length' field is not correct and instead its 'length' field should be used.

2022-10-22usb: gadget: uvc: fix sg handling in error caseDan Vacura2-7/+19
If there is a transmission error the buffer will be returned too early, causing a memory fault as subsequent requests for that buffer are still queued up to be sent. Refactor the error handling to wait for the final request to come in before reporting back the buffer to userspace for all transfer types (bulk/isoc/isoc_sg). This ensures userspace knows if the frame was successfully sent.

2022-10-22usb: gadget: uvc: fix dropped frame after missed isocDan Vacura1-1/+2
With the re-use of the previous completion status in 0d1c407b1a749 ("usb: dwc3: gadget: Return proper request status") it could be possible that the next frame would also get dropped if the current frame has a missed isoc error. Ensure that an interrupt is requested for the start of a new frame.

2022-10-22usb: dwc3: gadget: Don't delay End Transfer on delayed_statusThinh Nguyen1-1/+11
The gadget driver may wait on the request completion when it sets the USB_GADGET_DELAYED_STATUS. Make sure that the End Transfer command can go through if the dwc->delayed_status is set so that the request can complete. When the delayed_status is set, the Setup packet is already processed, and the next phase should be either Data or Status. It's unlikely that the host would cancel the control transfer and send a new Setup packet during End Transfer command. But if that's the case, we can try again when ep0state returns to EP0_SETUP_PHASE.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam Howlett. An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths. For optimizations by PMEM drivers, DRM drivers, etc. - vma merging improvements from Jakub Matěn. - NUMA hinting cleanups from David Hildenbrand. - xu xin added aditional userspace visibility into KSM merging activity. - THP & KSM code consolidation from Qi Zheng. - more folio work from Matthew Wilcox. - KASAN updates from Andrey Konovalov. - DAMON cleanups from Kaixu Xia. - DAMON work from SeongJae Park: fixes, cleanups. - hugetlb sysfs cleanups from Muchun Song. - Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.
