2011-03-28eeepc-wmi: asus generic asus-wmi.ko moduleCorentin Chary6-498/+681
New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.

New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load a module named eeepc-laptop on Asus Notebooks, start by copying all the code to asus-wmi.c. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2011-03-28hp-wmi: add rfkill support for wireless query 0x1bAnssi Hannula1-1/+187
Some recent HP laptops use a new wireless query command type 0x1b. Add support for it. Tested on HP Mini 5102. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2011-03-28hp-wmi: make rfkill initialization failure non-fatalAnssi Hannula1-3/+1
hp_wmi_rfkill_setup cleans up after itself now, so failing completely is no longer necessary. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2011-03-28hp-wmi: clear rfkill device pointers when appropriateAnssi Hannula1-0/+8
NULLify rfkill pointers during initialization. This prevents dereference of invalid pointer in case the driver is rebound and some rfkill device isn't detected anymore. Clear them also in hp_wmi_rfkill_setup failure path so that an rfkill initialization failure doesn't need to be fatal for the whole driver.

2011-03-28hp-wmi: split rfkill initialization out of hp_wmi_bios_setupAnssi Hannula1-17/+29
Split initialization of rfkill devices from hp_wmi_bios_setup() to hp_wmi_rfkill_setup(). This makes the code somewhat cleaner, especially with the future command 0x1b rfkill support. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2011-03-28hp-wmi: allow setting input and output buffer sizes separatelyAnssi Hannula1-24/+39
Split buffersize parameter of hp_wmi_perform_query to insize and outsize. Existing callers are changed to use the same value for insize and outsize to avoid any regressions, with the exception of hp_wmi_set_block where the output buffer is unused and therefore outsize is set to 0 (this change is not seen by BIOS code). The maximum input buffer size is kept at 4 bytes as per struct bios_args. Some commands exist that take longer buffers, but they haven't been implemented. The data portion of bios_args can be trivially made dynamically allocated later when such larger buffers become needed.

2011-03-28hp-wmi: remove a variable that is never readAnssi Hannula1-2/+1
Remove the status variable from hp_wmi_perform_query which holds the return value from wmi_evaluate_method(). It is never checked as the function bails out if the output buffer hasn't been allocated which indicates the call failed.

2011-03-28hp-wmi: check query return value in hp_wmi_perform_queryAnssi Hannula1-0/+16

Printing is suppressed for HPWMI_RET_UNKNOWN_CMDTYPE which is returned when the command type is unsupported.

2011-03-28sony-laptop: implement new backlight control methodMattia Dongili1-30/+79
Reasonably recent Vaios have a 0x12f or 0x137 handler that exposes a fine lid backlight regulation with values ranging from 0 to 255.

2011-03-28sony-laptop: implement keyboard backlight supportMattia Dongili1-1/+175
Recent Vaios have the opportunity to control the keyboard backlight via ACPI calls to the SNC device.

2011-03-28asus-laptop: remove deprecated interfaces (lcd_switch and display_get)Corentin Chary1-160/+3
I should have done that one year ago, so it's more than time to do it. These two features use non-standard interfaces. There are the only features that really need multiple path to guess what's the right method name on a specific laptop. Removing them allow to remove a lot of code an significantly clean the driver. This will affect the backlight code which won't be able to know if the backlight is on or off. The platform display file will also be write only (like the one in eeepc-laptop).

2011-03-28eeepc-wmi: serialize access to wmi methodCorentin Chary1-6/+72
\AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...

2011-03-28eeepc-wmi: add hotplug code for Eeepc 1000HCorentin Chary1-1/+273
Implement wireless like hotplug handling (code stolen from eeepc-laptop). Reminder: on some models rfkill is implemented by logically unplugging the wireless card from the PCI bus. Despite sending ACPI notifications, this does not appear to be implemented using standard ACPI hotplug - nor does the firmware provide the _OSC method required to support native PCIe hotplug. The only sensible choice appears to be to handle the hotplugging directly in the platform driver. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>
