Input: soc_button_array - add use_low_level_irq module parameter 2022-11-07T18:33:25+00:00 Hans de Goede hdegoede@redhat.com 2022-11-07T18:30:25+00:00 8e9ada1d0e72b4737df400fe1bba48dc42a68df7 It seems that the Windows drivers for the ACPI0011 soc_button_array device use low level triggered IRQs rather then using edge triggering. Some ACPI tables depend on this, directly poking the GPIO controller's registers to clear the trigger type when closing a laptop's/2-in-1's lid and re-instating the trigger when opening the lid again. Linux sets the edge/level on which to trigger to both low+high since it is using edge type IRQs, the ACPI tables then ends up also setting the bit for level IRQs and since both low and high level have been selected by Linux we get an IRQ storm leading to soft lockups. As a workaround for this the soc_button_array already contains a DMI quirk table with device models known to have this issue. Add a module parameter for this so that users can easily test if their device is affected too and so that they can use the module parameter as a workaround.
