The device occasionally wakes up from suspend with missing input on the internal keyboard and the following suspend attempt results in an instant wake-up. The quirks fix both issues for this device.

2025-10-01Drivers: hv: Add CONFIG_HYPERV_VMBUS optionMukesh Rathor
At present VMBus driver is hinged off of CONFIG_HYPERV which entails lot of builtin code and encompasses too much. It's not always clear what depends on builtin hv code and what depends on VMBus. Setting CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin adds even more confusion. VMBus is an independent module and should have its own config option. Also, there are scenarios like baremetal dom0/root where support is built in with CONFIG_HYPERV but without VMBus. Lastly, there are more features coming down that use CONFIG_HYPERV and add more dependencies on it. So, create a fine grained HYPERV_VMBUS option and update Kconfigs for dependency on VMBus.

2025-02-25Input: i8042 - swap old quirk combination with new quirk for more devicesWerner Sembach
Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. We could not activly retest these devices because we no longer have them in our archive, but based on the other old Clevo barebones we tested where the new quirk had the same or a better behaviour I think it would be good to apply it on these too.

2025-01-15Input: i8042 - Add support for platform filter contextsArmin Wolf
Currently the platform filter cannot access any driver-specific state which forces drivers installing a i8042 filter to have at least some kind of global pointer for their filter. Allow callers of i8042_install_filter() to submit a context pointer which is then passed to the i8042 filter. This frees drivers from the responsibility of having to manage this global pointer themself. Also introduce a separate type for the i8042 filter (i8042_filter_t) so that the function definitions can stay compact. Tested on a Dell Inspiron 3505.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/input/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in a few drivers.

2024-09-27[tree-wide] finally take no_llseek outAl Viro
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

2024-09-13Input: i8042 - add TUXEDO Stellaris 15 Slim Gen6 AMD to i8042 quirk tableWerner Sembach
The Gen6 devices have the same problem and the same Solution as the Gen5 ones. Some TongFang barebones have touchpad and/or keyboard issues after suspend, fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use, no negative effects could be observed when setting all four.

disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.

2024-08-18Input: i8042 - use new forcenorestore quirk to replace old buggy quirk ↵Werner Sembach
combination The old quirk combination sometimes cause a laggy keyboard after boot. With the new quirk the initial issue of an unresponsive keyboard after s3 resume is also fixed, but it doesn't have the negative side effect of the sometimes laggy keyboard.

2024-08-18Input: i8042 - add forcenorestore quirk to leave controller untouched even on s3Werner Sembach
On s3 resume the i8042 driver tries to restore the controller to a known state by reinitializing things, however this can confuse the controller with different effects. Mostly occasionally unresponsive keyboards after resume. These issues do not rise on s0ix resume as here the controller is assumed to preserved its state from before suspend. This patch adds a quirk for devices where the reinitialization on s3 resume is not needed and might be harmful as described above. It does this by using the s0ix resume code path at selected locations. This new quirk goes beyond what the preexisting reset=never quirk does, which only skips some reinitialization steps.
