* usb: typec: tcpm: set initial svdm version based on pd revisionRD Babiera2023-09-131-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c97cd0b4b54eb42aed7f6c3c295a2d137f6d2416 upstream. When sending Discover Identity messages to a Port Partner that uses Power Delivery v2 and SVDM v1, we currently send PD v2 messages with SVDM v2.0, expecting the port partner to respond with its highest supported SVDM version as stated in Section 6.4.4.2.3 in the Power Delivery v3 specification. However, sending SVDM v2 to some Power Delivery v2 port partners results in a NAK whereas sending SVDM v1 does not. NAK messages can be handled by the initiator (PD v3 section 6.4.4.2.5.1), and one solution could be to resend Discover Identity on a lower SVDM version if possible. But, Section 6.4.4.3 of PD v2 states that "A NAK response Should be taken as an indication not to retry that particular Command." Instead, we can set the SVDM version to the maximum one supported by the negotiated PD revision. When operating in PD v2, this obeys Section 6.4.4.2.3, which states the SVDM field "Shall be set to zero to indicate Version 1.0." In PD v3, the SVDM field "Shall be set to 01b to indicate Version 2.0."

* usb: typec: tcpci: clear the fault status bitMarco Felsch2023-09-061-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | commit 23e60c8daf5ec2ab1b731310761b668745fcf6ed upstream. According the "USB Type-C Port Controller Interface Specification v2.0" the TCPC sets the fault status register bit-7 (AllRegistersResetToDefault) once the registers have been reset to their default values. This triggers an alert(-irq) on PTN5110 devices albeit we do mask the fault-irq, which may cause a kernel hang. Fix this generically by writing a one to the corresponding bit-7.

* tcpm: Avoid soft reset when partner does not support get_statusBadhri Jagan Sridharan2023-09-061-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 78e0ea4277546debf7e96797ac3b768539cc44f6 upstream. When partner does not support get_status message, tcpm right now responds with soft reset message. This causes PD renegotiation to happen and resets PPS link. Avoid soft resetting the link when partner does not support get_status message to mitigate PPS resets.

| | | | | | | | | | | | | | | | | | | If dwc3 is runtime suspended we defer processing the event buffer until resume, by setting the pending_events flag. Set this flag before triggering resume to avoid race with the runtime resume callback. While handling the pending events, in addition to checking the event buffer we also need to process it. Handle this by explicitly calling dwc3_thread_interrupt(). Also balance the runtime pm get() operation that triggered this processing.

What should happen if the transfer fails isn't entirely clear, but a reasonably conservative approach is to pretend that no media is present. A similar problem exists in a usb_stor_dbg() call in alauda_get_media_status(). In this case, when an error occurs the call is redundant, because usb_stor_ctrl_transfer() already will print a debugging message. Finally, unrelated to the uninitialized memory access, is the fact that alauda_check_media() performs DMA to a buffer on the stack. Fortunately usb-storage provides a general purpose DMA-able buffer for uses like this. We'll use it instead.

* USB: Gadget: core: Help prevent panic during UVC unconfigureAlan Stern2023-08-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avichal Rakesh reported a kernel panic that occurred when the UVC gadget driver was removed from a gadget's configuration. The panic involves a somewhat complicated interaction between the kernel driver and a userspace component (as described in the Link tag below), but the analysis did make one thing clear: The Gadget core should accomodate gadget drivers calling usb_gadget_deactivate() as part of their unbind procedure. Currently this doesn't work. gadget_unbind_driver() calls driver->unbind() while holding the udc->connect_lock mutex, and usb_gadget_deactivate() attempts to acquire that mutex, which will result in a deadlock. The simple fix is for gadget_unbind_driver() to release the mutex when invoking the ->unbind() callback. There is no particular reason for it to be holding the mutex at that time, and the mutex isn't held while the ->bind() callback is invoked. So we'll drop the mutex before performing the unbind callback and reacquire it afterward. We'll also add a couple of comments to usb_gadget_activate() and usb_gadget_deactivate(). Because they run in process context they must not be called from a gadget driver's ->disconnect() callback, which (according to the kerneldoc for struct usb_gadget_driver in include/linux/usb/gadget.h) may run in interrupt context. This may help prevent similar bugs from arising in the future.

* usb: typec: altmodes/displayport: Signal hpd when configuring pin assignmentRD Babiera2023-08-041-1/+17
| | | | | | | | | | | | | | | | | | | | When connecting to some DisplayPort partners, the initial status update after entering DisplayPort Alt Mode notifies that the DFP_D/UFP_D is not in the connected state. This leads to sending a configure message that keeps the device in USB mode. The port partner then sets DFP_D/UFP_D to the connected state and HPD to high in the same Attention message. Currently, the HPD signal is dropped in order to handle configuration. This patch saves changes to the HPD signal when the device chooses to configure during dp_altmode_status_update, and invokes sysfs_notify if necessary for HPD after configuring.

* usb: dwc3: pci: skip BYT GPIO lookup table for hardwired phyGratian Crisan2023-07-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware based on the Bay Trail / BYT SoCs require an external ULPI phy for USB device-mode. The phy chip usually has its 'reset' and 'chip select' lines connected to GPIOs described by ACPI fwnodes in the DSDT table. Because of hardware with missing ACPI resources for the 'reset' and 'chip select' GPIOs commit 5741022cbdf3 ("usb: dwc3: pci: Add GPIO lookup table on platforms without ACPI GPIO resources") introduced a fallback gpiod_lookup_table with hard-coded mappings for Bay Trail devices. However there are existing Bay Trail based devices, like the National Instruments cRIO-903x series, where the phy chip has its 'reset' and 'chip-select' lines always asserted in hardware via resistor pull-ups. On this hardware the phy chip is always enabled and the ACPI dsdt table is missing information not only for the 'chip-select' and 'reset' lines but also for the BYT GPIO controller itself "INT33FC". With the introduction of the gpiod_lookup_table initializing the USB device-mode on these hardware now errors out. The error comes from the gpiod_get_optional() calls in dwc3_pci_quirks() which will now return an -ENOENT error due to the missing ACPI entry for the INT33FC gpio controller used in the aforementioned table. This hardware used to work before because gpiod_get_optional() will return NULL instead of -ENOENT if no GPIO has been assigned to the requested function. The dwc3_pci_quirks() code for setting the 'cs' and 'reset' GPIOs was then skipped (due to the NULL return). This is the correct behavior in cases where the phy chip is hardwired and there are no GPIOs to control. Since the gpiod_lookup_table relies on the presence of INT33FC fwnode in ACPI tables only add the table if we know the entry for the INT33FC gpio controller is present. This allows Bay Trail based devices with hardwired dwc3 ULPI phys to continue working.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit b138e23d3dff90c0494925b4c1874227b81bddf7. AutoRetry has been found to sometimes cause controller freezes when communicating with buggy USB devices. This controller feature allows the controller in host mode to send non-terminating/burst retry ACKs instead of terminating retry ACKs to devices when a transaction error (CRC error or overflow) occurs. Unfortunately, if the USB device continues to respond with a CRC error, the controller will not complete endpoint-related commands while it keeps trying to auto-retry. [3] The xHCI driver will notice this once it tries to abort the transfer using a Stop Endpoint command and does not receive a completion in time. [1] This situation is reported to dmesg: [sda] tag#29 uas_eh_abort_handler 0 uas-tag 1 inflight: CMD IN [sda] tag#29 CDB: opcode=0x28 28 00 00 69 42 80 00 00 48 00 xhci-hcd: xHCI host not responding to stop endpoint command xhci-hcd: xHCI host controller not responding, assume dead xhci-hcd: HC died; cleaning up Some users observed this problem on an Odroid HC2 with the JMS578 USB3-to-SATA bridge. The issue can be triggered by starting a read-heavy workload on an attached SSD. After a while, the host controller would die and the SSD would disappear from the system. [1] Further analysis by Synopsys determined that controller revisions other than the one in Odroid HC2 are also affected by this. The recommended solution was to disable AutoRetry altogether. This change does not have a noticeable performance impact. [2] Revert the enablement commit. This will keep the AutoRetry bit in the default state configured during SoC design [2].

However from time to time it drops completely off the USB bus during resume. Below is captured occurrence of such an event: <Suspend> <Resume> <Reset>/<Chirp J>/<Tiny J> <Reset>/<Chirp K>/<Tiny K> <High Speed> <Corrupted packet> <Reset/Target disconnected> To fix the condition a user has to unplug and plug the device again. With USB_QUIRK_RESET_RESUME applied ("usbcore.quirks=1235:8211:b") for the Scarlett audio device the issue still reproduces. Applying USB_QUIRK_DISCONNECT_SUSPEND ("usbcore.quirks=1235:8211:m") fixed the issue and the Scarlett audio device didn't drop off the USB bus for ~5000 suspend/resume cycles where originally issue reproduced in ~100 or less suspend/resume cycles.

| | | | | | | | | | | | | | | | | Commit c4a5153e87fd ("usb: dwc3: core: Power-off core/PHYs on system_suspend in host mode") replaces check for HOST only dr_mode with current_dr_role. But during booting, the current_dr_role isn't initialized, thus the device side reset is always issued even if dwc3 was configured as host-only. What's more, on some platforms with host only dwc3, aways issuing device side reset by accessing device register block can cause kernel panic.

| | | | | | | | | | | | | | | | | | | | | | | | There are situations during the xhci_resume() sequence, which allows for re-initializing of the XHCI HC. However, in case the HCD is being removed, these operations may not be needed. Set the removal state before issuing the runtime PM get on the XHCI device, so that the XHCI resume routine will know when to bypass the re-init logic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During XHCI resume, if there was a host controller error detected the routine will attempt to re-initialize the XHCI HC, so that it can return back to an operational state. If the XHCI host controller is being removed, this sequence would be already handled within the XHCI halt path, leading to a duplicate set of reg ops/calls. In addition, since the XHCI bus is being removed, the overhead added in restarting the HCD is unnecessary. Check for the XHC state before setting the reinit_xhc parameter, which is responsible for triggering the restart.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In scenarios where pullup relies on resume (get sync) to initialize the controller and set the run stop bit, then core_init is followed by gadget_resume which will eventually set run stop bit. But in cases where the core_init fails, the return value is not sent back to udc appropriately. So according to UDC the controller has started but in reality we never set the run stop bit. On systems like Android, there are uevents sent to HAL depending on whether the configfs_bind / configfs_disconnect were invoked. In the above mentioned scnenario, if the core init fails, the run stop won't be set and the cable plug-out won't result in generation of any disconnect event and userspace would never get any uevent regarding cable plug out and we never call pullup(0) again. Furthermore none of the next Plug-In/Plug-Out's would be known to configfs. Return back the appropriate result to UDC to let the userspace/ configfs know that the pullup failed so they can take appropriate action.
