If the platform supports these fan modes, set up platform_profile to change these modes. If not supported, skip enabling platform_profile. Signed-off-by: Lyndon Sanche --- v4: - Make thermal_init and thermal_cleanup static - Rearrange order of added includes, did not edit current includes - Include bits.h - Switch comment style - Return error if platform_profile registering failed - Add thermal calls to call_blacklist - Align defines with tabs - Correct separation of function and error handling - Propagate error codes up v3: - Convert smbios-thermal-ctl docs to multiline comment and wrap - Change thermal_mode_bits enum to directly be BIT() values - Convert related code to use this - Use FIELD_GET/PREP and GENNMASK for getting/setting thermal modes - Correct offset for getting current ACC mode, setting offset unchanged - Check if thermal_handler is allocated before freeing and unregistering platform_profile v2: - Wrap smbios-thermal-ctl comment - Return proper error code when invalid state returned - Simplify platform_profile_get returns - Propogate ENOMEM error --- drivers/platform/x86/dell/dell-laptop.c | 238 +++++++++++++++++++ drivers/platform/x86/dell/dell-smbios-base.c | 2 + drivers/platform/x86/dell/dell-smbios.h | 1 + 3 files changed, 241 insertions(+) diff --git a/drivers/platform/x86/dell/dell-laptop.c b/drivers/platform/x86/dell/dell-laptop.c index 42f7de2b4522..530ee6079447 100644 --- a/drivers/platform/x86/dell/dell-laptop.c +++ b/drivers/platform/x86/dell/dell-laptop.c @@ -27,6 +27,9 @@ #include #include #include +#include +#include +#include #include #include "dell-rbtn.h" #include "dell-smbios.h" @@ -95,6 +98,7 @@ static struct backlight_device *dell_backlight_device; static struct rfkill *wifi_rfkill; static struct rfkill *bluetooth_rfkill; static struct rfkill *wwan_rfkill; +static struct platform_profile_handler *thermal_handler; static bool force_rfkill; static bool micmute_led_registered; static bool mute_led_registered; @@ -2199,6 +2203,232 @@ static int mute_led_set(struct led_classdev *led_cdev, return 0; } +/* Derived from smbios-thermal-ctl + * + * cbClass 17 + * cbSelect 19 + * User Selectable Thermal Tables(USTT) + * cbArg1 determines the function to be performed + * cbArg1 0x0 = Get Thermal Information + * cbRES1 Standard return codes (0, -1, -2) + * cbRES2, byte 0 Bitmap of supported thermal modes.
