Some newer Sony laptops (seems to be -limited to new FX series laptops, at least the FX501 and the FX702) lack a -sonypi device and are not supported at all by this driver. - -It will give access (through a user space utility) to some events those laptops -generate, like: - - jogdial events (the small wheel on the side of Vaios) - - capture button events (only on Vaio Picturebook series) - - Fn keys - - bluetooth button (only on C1VR model) - - programmable keys, back, help, zoom, thumbphrase buttons, etc. - (when available) - -Those events (see linux/sonypi.h) can be polled using the character device node -/dev/sonypi (major 10, minor auto allocated or specified as a option). -A simple daemon which translates the jogdial movements into mouse wheel events -can be downloaded at: <http://popies.net/sonypi/> - -Another option to intercept the events is to get them directly through the -input layer. - -This driver supports also some ioctl commands for setting the LCD screen -brightness and querying the batteries charge information (some more -commands may be added in the future). - -This driver can also be used to set the camera controls on Picturebook series -(brightness, contrast etc), and is used by the video4linux driver for the -Motion Eye camera. - -Please note that this driver was created by reverse engineering the Windows -driver and the ACPI BIOS, because Sony doesn't agree to release any programming -specs for its laptops. If someone convinces them to do so, drop me a note. - -Driver options: ---------------- - -Several options can be passed to the sonypi driver using the standard -module argument syntax (<param>=<value> when passing the option to the -module or sonypi.<param>=<value> on the kernel boot line when sonypi is -statically linked into the kernel). Those options are: - - minor: minor number of the misc device /dev/sonypi, - default is -1 (automatic allocation, see /proc/misc - or kernel logs) - - camera: if you have a PictureBook series Vaio (with the - integrated MotionEye camera), set this parameter to 1 - in order to let the driver access to the camera - - fnkeyinit: on some Vaios (C1VE, C1VR etc), the Fn key events don't - get enabled unless you set this parameter to 1. - Do not use this option unless it's actually necessary, - some Vaio models don't deal well with this option. - This option is available only if the kernel is - compiled without ACPI support (since it conflicts - with it and it shouldn't be required anyway if - ACPI is already enabled). - - verbose: set to 1 to print unknown events received from the - sonypi device. - set to 2 to print all events received from the - sonypi device. - - compat: uses some compatibility code for enabling the sonypi - events. If the driver worked for you in the past - (prior to version 1.5) and does not work anymore, - add this option and report to the author. - - mask: event mask telling the driver what events will be - reported to the user. This parameter is required for - some Vaio models where the hardware reuses values - used in other Vaio models (like the FX series who does - not have a jogdial but reuses the jogdial events for - programmable keys events). The default event mask is - set to 0xffffffff, meaning that all possible events - will be tried. You can use the following bits to - construct your own event mask (from - drivers/char/sonypi.h): - SONYPI_JOGGER_MASK 0x0001 - SONYPI_CAPTURE_MASK 0x0002 - SONYPI_FNKEY_MASK 0x0004 - SONYPI_BLUETOOTH_MASK 0x0008 - SONYPI_PKEY_MASK 0x0010 - SONYPI_BACK_MASK 0x0020 - SONYPI_HELP_MASK 0x0040 - SONYPI_LID_MASK 0x0080 - SONYPI_ZOOM_MASK 0x0100 - SONYPI_THUMBPHRASE_MASK 0x0200 - SONYPI_MEYE_MASK 0x0400 - SONYPI_MEMORYSTICK_MASK 0x0800 - SONYPI_BATTERY_MASK 0x1000 - SONYPI_WIRELESS_MASK 0x2000 - - useinput: if set (which is the default) two input devices are - created, one which interprets the jogdial events as - mouse events, the other one which acts like a - keyboard reporting the pressing of the special keys. - -Module use: ------------ - -In order to automatically load the sonypi module on use, you can put those -lines in your /etc/modprobe.conf file: - - alias char-major-10-250 sonypi - options sonypi minor=250 - -This supposes the use of minor 250 for the sonypi device: - - # mknod /dev/sonypi c 10 250 - -Bugs: ------ - - - several users reported that this driver disables the BIOS-managed - Fn-keys which put the laptop in sleeping state, or switch the - external monitor on/off. There is no workaround yet, since this - driver disables all APM management for those keys, by enabling the - ACPI management (and the ACPI core stuff is not complete yet). If - you have one of those laptops with working Fn keys and want to - continue to use them, don't use this driver. - - - some users reported that the laptop speed is lower (dhrystone - tested) when using the driver with the fnkeyinit parameter. I cannot - reproduce it on my laptop and not all users have this problem. - This happens because the fnkeyinit parameter enables the ACPI - mode (but without additional ACPI control, like processor - speed handling etc). Use ACPI instead of APM if it works on your - laptop. - - - sonypi lacks the ability to distinguish between certain key - events on some models. - - - some models with the nvidia card (geforce go 6200 tc) uses a - different way to adjust the backlighting of the screen. There - is a userspace utility to adjust the brightness on those models, - which can be downloaded from - http://www.acc.umu.se/~erikw/program/smartdimmer-0.1.tar.bz2 - - - since all development was done by reverse engineering, there is - _absolutely no guarantee_ that this driver will not crash your - laptop. Permanently. |
