2024-12-02module: Convert symbol namespace to string literalPeter Zijlstra
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-11-25Revert "HID: bpf: allow write access to quirks field in struct hid_device"Linus Torvalds
This reverts commit 6fd47effe92b, and the related self-test update commit e14e0eaeb040 ("selftests/hid: add test for assigning a given device to hid-generic"). It results in things like the scroll wheel on Logitech mice not working after a reboot due to the kernel being confused about the state of the high-resolution mode. Quoting Benjamin Tissoires: "The idea of 6fd47effe92b was to be able to call hid_bpf_rdesc_fixup() once per reprobe of the device. However, because the bpf filter can now change the quirk value, the call had to be moved before the driver gets bound (which was previously ensuring the unicity of the call). The net effect is that now, in the case hid-generic gets loaded first and then the specific driver gets loaded once the disk is available, the value of ->quirks is not reset, but kept to the value that was set by hid-generic (HID_QUIRK_INPUT_PER_APP). Once hid-logitech-hidpp kicks in, that quirk is now set, which creates two inputs for the single mouse: one keyboard for fancy shortcuts, and one mouse node. However, hid-logitech-hidpp expects only one input node to be attached (it stores it into hidpp->input), and when a wheel event is received, because there is some processing with high-resolution wheel events, the wheel event is injected into hidpp->input. And of course, when HID_QUIRK_INPUT_PER_APP is set, hidpp->input gets the keyboard node, which doesn't have wheel event type, and the events are ignored" Reported-and-bisected-by: Mike Galbraith <efault@gmx.de> Link: https://lore.kernel.org/all/CAHk-=wiUkQM3uheit2cNM0Y0OOY5qqspJgC8LkmOkJ2p2LDxcw@mail.gmail.com/ Acked-by: Benjamin Tissoires <bentiss@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

mt_set_mode() accepts 2 boolean switches indicating whether the device (if it follows Windows Precision Touchpad specification) should report hardware buttons and/or surface contacts. For a casual reader it is completely not clear, as they look at the call site, which exact mode is being requested. Define report_mode enum and change mt_set_mode() to accept is as an argument instead. This allows to write: mt_set_modes(hdev, HID_LATENCY_NORMAL, TOUCHPAD_REPORT_ALL); or mt_set_modes(hdev, HID_LATENCY_HIGH, TOUCHPAD_REPORT_BUTTONS); which makes intent much more clear.

And the issue seems to be that the corresponding devres group is not allocated. Normally, devres_open_group() is called from __hid_device_probe() but Hyper-V HID driver overrides 'hid_dev->driver' with 'mousevsc_hid_driver' stub and basically re-implements __hid_device_probe() by calling hid_parse() and hid_hw_start() but not devres_open_group(). hid_device_probe() does not call __hid_device_probe() for it. Later, when the driver is removed, hid_device_remove() calls devres_release_group() as it doesn't check whether hdev->driver was initially overridden or not. The issue seems to be related to the commit 62c68e7cee33 ("HID: ensure timely release of driver-allocated resources") but the commit itself seems to be correct. Fix the issue by dropping the 'hid_dev->driver' override and using hid_register_driver()/hid_unregister_driver() instead. Alternatively, it would have been possible to rely on the default handling but HID_CONNECT_DEFAULT implies HID_CONNECT_HIDRAW and it doesn't seem to work for mousevsc as-is.

2024-10-18HID: wacom: Set eraser status when either 'Eraser' or 'Invert' usage is setJason Gerecke
Microsoft defines two slightly different behaviors for pens that are being used to erase. The first one, for pens that can be used while inverted specifies that both 'Invert' and 'Eraser' usages should be set while the pen is in contact and erasing. For pens that use an eraser button though, they specify that only the 'Eraser' usage should be set (while hovering, only the 'Invert' usage is to be set). We used our internal 'invert_state' flag to determine if a pen has an intent to erase (whether hovering or not). That flag was previously only depending on the 'Invert' usage, which was sufficient for the first type of pen (EMR) but not the second type (AES). This commit makes the flag depend on either usage being set, and also renames it to make its function more clear. This change should not normally have an impact on userspace due to both the existing driver and firmware design. The driver already only determines tool type based on the first event in an interaction (e.g. it will see the 'Invert' bit set when the eraser comes into prox and then report BTN_TOOL_RUBBER for the rest of the interaction, even if 'Invert' is cleared). AES firmware is also careful to send reports that work through a set of defined state transitions, even in the corner-case where the eraser button is pressed when the pen is already in contact with the display (Prox|Tip -> Prox -> 0 -> Invert -> Eraser). Regardless, it seems reasonable to ensure the driver's state variables match programmer expectation.

Patch for Goodix 27c6:0d42 touchpads found in Inspiron 5515 laptops. After resume from suspend, one can communicate with this device just fine. We can read data from it or request a reset, but for some reason the interrupt line will not go up when new events are available. (it can correctly respond to a reset with an interrupt tho) The only way I found to wake this device up is to send anything to it after ~1.5s mark, for example a simple read request, or power mode change. In this patch, I simply delay the resume steps with msleep, this will cause the set_power request to happen after the ~1.5s barrier causing the device to resume its event interrupts. Sleep was used rather than delayed_work to make this workaround as non-invasive as possible.

A default case statement with a bare unreachable() was recently added to fetch_item(), which by itself introduces undefined behavior. objtool points this out with a few different warnings, depending on configuration and compiler: vmlinux.o: warning: objtool: fetch_item() falls through to next function ... vmlinux.o: warning: objtool: hid_open_report() falls through to next function hid_parser_main() vmlinux.o: warning: objtool: hid_scan_report() falls through to next function hid_allocate_device() vmlinux.o: warning: objtool: hid_open_report+0x21b: can't find jump dest instruction at .text.hid_open_report+0x40f Replacing unreachable() with BUG() is a typical fix to eliminate the undefined behavior and make the default case well defined. However, in this case, all possible values are enumerated in the switch statement, so the default case can never actually happen, as proven with the comment next to the item->size assignment. Just remove the default case altogether, as the return statement would still be valid if the switch statement were ever to be skipped.

2024-10-11HID: intel-ish-hid: Add firmware version sysfs attributesZhang Lixu
Introduce sysfs attributes to the intel-ish-ipc driver to expose the base and project firmware versions for ISH devices that load firmware from the host. The build tool embeds these versions into the ISH global manifest within the firmware binary during the firmware build process. The driver, upon loading the firmware, extracts this version information from the manifest and makes it accessible via sysfs. The base version corresponds to the firmware version provided in Intel's Firmware Development Kit (FDK), while the project version reflects the vendor-customized firmware derived from the FDK. These attributes provide userspace tools and applications with the ability to easily query the firmware versions, which is essential for firmware validation and troubleshooting. Example usages: $ cat /sys/devices/pci0000\:00/0000\:00\:12.0/firmware/base_version 5.8.0.7716 $ cat /sys/devices/pci0000\:00/0000\:00\:12.0/firmware/project_version 5.8.0.12472 Signed-off-by: Zhang Lixu <lixu.zhang@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>

2024-10-11HID: wacom: Hardcode (non-inverted) AES pens as BTN_TOOL_PENJason Gerecke
Unlike EMR tools which encode type information in their tool ID, tools for AES sensors are all "generic pens". It is inappropriate to make use of the wacom_intuos_get_tool_type function when dealing with these kinds of devices. Instead, we should only ever report BTN_TOOL_PEN or BTN_TOOL_RUBBER, as depending on the state of the Eraser and Invert bits.

Using the device-managed version allows to simplify clean-up in probe() error path. Additionally, this device-managed ensures proper cleanup, which helps to resolve memory errors, page faults, btrfs going read-only, and btrfs disk corruption.

The behavior of HONOR MagicBook Art 14 touchpad is not consistent after reboots, as sometimes it reports itself as a touchpad, and sometimes as a mouse. Similarly to GLO-GXXX it is possible to call MT_QUIRK_FORCE_GET_FEATURE as a workaround to force set feature in mt_set_input_mode() for such special touchpad device.
