The TUXEDO Sirius 16 Gen1 and TUXEDO Sirius 16 Gen2 devices have a per-key controllable RGB keyboard backlight. The firmware API for it is implemented via WMI. To make the backlight userspace configurable this driver emulates a LampArray HID device and translates the input from hidraw to the corresponding WMI calls. This is a new approach as the leds subsystem lacks a suitable UAPI for per-key keyboard backlights, and like this no new UAPI needs to be established. v2: Integrated Armins feedback and fixed kernel test robot warnings. v3: Fixed borked the subject line of v2 Co-developed-by: Christoffer Sandberg <cs@xxxxxxxxx> Signed-off-by: Christoffer Sandberg <cs@xxxxxxxxx> Signed-off-by: Werner Sembach <wse@xxxxxxxxxxxxxxxxxxx> Link: https://lore.kernel.org/all/1fb08a74-62c7-4d0c-ba5d-648e23082dcb@xxxxxxxxxxxxxxxxxxx/ --- MAINTAINERS | 6 + drivers/platform/x86/Kconfig | 2 + drivers/platform/x86/Makefile | 3 + drivers/platform/x86/tuxedo/Kbuild | 9 + drivers/platform/x86/tuxedo/Kconfig | 14 + .../x86/tuxedo/tuxedo_nb04_wmi_ab_init.c | 90 +++ .../x86/tuxedo/tuxedo_nb04_wmi_ab_init.h | 20 + .../tuxedo_nb04_wmi_ab_virtual_lamp_array.c | 739 ++++++++++++++++++ .../tuxedo_nb04_wmi_ab_virtual_lamp_array.h | 18 + .../x86/tuxedo/tuxedo_nb04_wmi_util.c | 85 ++ .../x86/tuxedo/tuxedo_nb04_wmi_util.h | 112 +++ 11 files changed, 1098 insertions(+) create mode 100644 drivers/platform/x86/tuxedo/Kbuild create mode 100644 drivers/platform/x86/tuxedo/Kconfig create mode 100644 drivers/platform/x86/tuxedo/tuxedo_nb04_wmi_ab_init.c create mode 100644 drivers/platform/x86/tuxedo/tuxedo_nb04_wmi_ab_init.h create mode 100644 drivers/platform/x86/tuxedo/tuxedo_nb04_wmi_ab_virtual_lamp_array.c create mode 100644 drivers/platform/x86/tuxedo/tuxedo_nb04_wmi_ab_virtual_lamp_array.h create mode 100644 drivers/platform/x86/tuxedo/tuxedo_nb04_wmi_util.c create mode 100644 drivers/platform/x86/tuxedo/tuxedo_nb04_wmi_util.h diff --git a/MAINTAINERS b/MAINTAINERS index cc40a9d9b8cd1..3385ad51af194 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -23358,6 +23358,12 @@ T: git git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux.git turbostat F: tools/power/x86/turbostat/ F: tools/testing/selftests/turbostat/ +TUXEDO DRIVERS +M: Werner Sembach <wse@xxxxxxxxxxxxxxxxxxx> +L: platform-driver-x86@xxxxxxxxxxxxxxx +S: Supported +F: drivers/platform/x86/tuxedo/ + TW5864 VIDEO4LINUX DRIVER M: Bluecherry Maintainers <maintainers@xxxxxxxxxxxxxxxxx> M: Andrey Utkin <andrey.utkin@xxxxxxxxxxxxxxxxxxx> diff --git a/drivers/platform/x86/Kconfig b/drivers/platform/x86/Kconfig index ddfccc226751f..c7cffb222adac 100644 --- a/drivers/platform/x86/Kconfig +++ b/drivers/platform/x86/Kconfig @@ -1196,3 +1196,5 @@ config P2SB The main purpose of this library is to unhide P2SB device in case firmware kept it hidden on some platforms in order to access devices behind it. + +source "drivers/platform/x86/tuxedo/Kconfig" diff --git a/drivers/platform/x86/Makefile b/drivers/platform/x86/Makefile index e1b1429470674..1562dcd7ad9a5 100644 --- a/drivers/platform/x86/Makefile +++ b/drivers/platform/x86/Makefile @@ -153,3 +153,6 @@ obj-$(CONFIG_WINMATE_FM07_KEYS) += winmate-fm07-keys.o # SEL obj-$(CONFIG_SEL3350_PLATFORM) += sel3350-platform.o + +# TUXEDO +obj-y += tuxedo/ diff --git a/drivers/platform/x86/tuxedo/Kbuild b/drivers/platform/x86/tuxedo/Kbuild new file mode 100644 index 0000000000000..5a3506ab98131 --- /dev/null +++ b/drivers/platform/x86/tuxedo/Kbuild @@ -0,0 +1,9 @@ +# SPDX-License-Identifier: GPL-2.0-only +# +# TUXEDO X86 Platform Specific Drivers +# + +tuxedo_nb04_wmi_ab-y := tuxedo_nb04_wmi_ab_init.o +tuxedo_nb04_wmi_ab-y += tuxedo_nb04_wmi_util.o +tuxedo_nb04_wmi_ab-y += tuxedo_nb04_wmi_ab_virtual_lamp_array.o +obj-$(CONFIG_TUXEDO_NB04_WMI_AB) += tuxedo_nb04_wmi_ab.o diff --git a/drivers/platform/x86/tuxedo/Kconfig b/drivers/platform/x86/tuxedo/Kconfig new file mode 100644 index 0000000000000..b1f7c6ceeaae4 --- /dev/null +++ b/drivers/platform/x86/tuxedo/Kconfig @@ -0,0 +1,14 @@ +# SPDX-License-Identifier: GPL-2.0-only +# +# TUXEDO X86 Platform Specific Drivers +# + +menuconfig TUXEDO_NB04_WMI_AB + tristate "TUXEDO NB04 WMI AB Platform Driver" + default m + help + This driver implements the WMI AB device found on TUXEDO Notebooks + with board vendor NB04.
