These patches are made against current mainline kernel and also available at git://kernel.ubuntu.com/ikepanhc/ideapad-laptop.git for-upstream Once the rfkill of a laptop is set to block, it is no way to unblock with Linux without driver. Thanks for David Woodhouse wrote the first driver solving this. But the \_SB_.GECN and \_SB_.DECN are only available on Lenovo ideapad S10-3. Using EC command to control rf/camera power is better because I believe every ideapads which has VPC2004 device in its DSDT has this common method. This driver is tested on Lenovo ideapad B550 and ideapad S10-3 and also tested by Mario 'BitKoenig' Holbe on Lenovo ideapad S12-VIA. Changes after last posted: * Add schedule() to yield processor when waiting EC. * Using time_before() to check timeout. * Maximun waiting for EC execution increasing to 100ms in case that we have a slow EC. * Add parameter: no_bt_rfkill for not setup bluetooth rfkill. Next step for this driver: * Hotkey enablement. Ike Panhc (9): ideapad: add ACPI helpers ideapad: check VPC bit before sync rfkill hw status ideapad: make sure we bind on the correct device ideapad: use return value of _CFG to tell if device exist or not ideapad: use EC command to control camera ideapad: rewrite the hw rfkill notify ideapad: rewrite the sw rfkill set ideapad: Change the driver name to ideapad-laptop ideapad: Add param: no_bt_rfkill drivers/platform/x86/Kconfig | 4 +- drivers/platform/x86/Makefile | 2 +- drivers/platform/x86/ideapad-laptop.c | 394 +++++++++++++++++++++++++++++++++ drivers/platform/x86/ideapad_acpi.c | 306 ------------------------- 4 files changed, 397 insertions(+), 309 deletions(-) create mode 100644 drivers/platform/x86/ideapad-laptop.c delete mode 100644 drivers/platform/x86/ideapad_acpi.c -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
