* toshiba_acpi: Fix machines that don't support HCI_SYSTEM_EVENTSeth Forshee2011-12-051-5/+16
| | | | | | | | | | | | | The Satellite C670-10V generates notifications for hotkeys but does not support HCI_SYSTEM_EVENT. As a result when a hotkey is pressed it gets stuck in an infinite loop in toshiba_acpi_notify. To fix this, detect whether or not HCI_SYSTEM_EVENT is supported up-front and don't try to read system events if it isn't supported. In addition, limit the number of retries when reading HCI_SYSTEM_EVENT fails so that this loop cannot run unbounded.

The driver doesn't check the result and directly uses it as some sort of divisor in some places: msleep(lis3->pwron_delay / lis3lv02d_get_odr()); Under this circumstances, this could very well cause the "divide by zero" exception from above. For now, I fixed it the easiest and most obvious way: Check if the result is sane and if it isn't use a sane default instead. I went for "100" in the latter case, simply because /sys/devices/platform/lis3lv02d/rate returns it on a successful boot.

Some of machines still keep the old WMID_GUID1 method but more and more machines were already removed old wmi methods from DSDT. So, this patch add a new ACER_WMID_v2 interface flag to represent new acer notebooks, the following is definition: + ACER_WMID: It means this machine only provides WMID_GUID1/2 methods. + ACER_WMID_v2: It means this machine provide new WMID_GUID3 and WMID_EVENT_GUID methods. Some ACER_WMID_v2 machines also provide old WMID_GUID1/2 methods, but we still query/set communication device's state by new WMID_GUID3 method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add three new rfkill switches in this driver that are specific to Pegatron Lucid tablet. Please note that you might not need all three switches. For example if you don't have a 3G module inside your tablet. Also, on my device, the gpio for the wifi/bt module is connected to the bluetooth line. Therefore to activate your wireless lan interface, you need to use the "pega-bt" rfkill switch. Finally, the rfkill switch only works before the wireless module is loaded the first time. Unloading ath9k doesn't help, a reboot is necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Novo key is the Lenovo define key on every ideapads, which has two definition. Long press and short click. Driver will report KEY_PROG1 on short click and KEY_PROG2 when long press. On pre-install OS for ideapads there are application waiting for the event and there is no such application for Linux yet, so I think to report KEY_PROG is fine in anyway. Also change the scancode from hex to decimal because they are related to vpc bit in notify function which is in decimal.

| * Platform: Detect samsung laptop quirk when initial level is zeroJohn Serock2011-10-241-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch depends on the "Platform: Brightness quirk for samsung laptop driver" patch from Jason Stubbs. This patch adds a check for an initial brightness level of 0; if the level is 0, this patch changes the brightness level to 1 before the driver attempts to detect the brightness quirk. The Samsung N150 netbook experiences the brightness quirk. Without Jason's patch, the only brightness levels available on the N150 are 0, 1, and 8. This patch ensures that, when the initial brightness level is 0, the samsang-laptop driver detects the brightness quirk on the N150, thereby making brightness levels 0 through 8 available.
