Thus enabling debug messages will be +useful for finding unknown event codes. + +EC ACPI interface description +============================= + +The ``INOU0000`` ACPI device is a virtual device used to access various hardware registers +available on notebooks manufactured by Uniwill. Reading and writing those registers happens +by calling ACPI control methods. The ``uniwill-laptop`` driver uses this device to communicate +with the EC because the ACPI control methods are faster than the WMI methods described above. + +ACPI control methods used for reading registers take a single ACPI integer containing the address +of the register to read and return a ACPI integer containing the data inside said register. ACPI +control methods used for writing registers however take two ACPI integers, with the additional +ACPI integer containing the data to be written into the register. Such ACPI control methods return +nothing. + +System memory +------------- + +System memory can be accessed with a granularity of either a single byte (``MMRB`` for reading and +``MMWB`` for writing) or four bytes (``MMRD`` for reading and ``MMWD`` for writing). Those ACPI +control methods are unused because they provide no benefit when compared to the native memory +access functions provided by the kernel. + +EC RAM +------ + +The internal RAM of the EC can be accessed with a granularity of a single byte using the ``ECRR`` +(read) and ``ECRW`` (write) ACPI control methods, with the maximum register address being ``0xFFF``. +The OEM software waits 6 ms after calling one of those ACPI control methods, likely to avoid +overwhelming the EC when being connected over LPC. + +PCI config space +---------------- + +The PCI config space can be accessed with a granularity of four bytes using the ``PCRD`` (read) and +``PCWD`` (write) ACPI control methods. The exact address format is unknown, and poking random PCI +devices might confuse the PCI subsystem. Because of this those ACPI control methods are not used. + +IO ports +-------- + +IO ports can be accessed with a granularity of four bytes using the ``IORD`` (read) and ``IOWD`` +(write) ACPI control methods. Those ACPI control methods are unused because they provide no benefit +when compared to the native IO port access functions provided by the kernel. + +CMOS RAM +-------- + +The CMOS RAM can be accessed with a granularity of a single byte using the ``RCMS`` (read) and +``WCMS`` ACPI control methods. Using those ACPI methods might interfere with the native CMOS RAM +access functions provided by the kernel due to the usage of indexed IO, so they are unused. + +Indexed IO +---------- + +Indexed IO with IO ports with a granularity of a single byte can be performed using the ``RIOP`` +(read) and ``WIOP`` (write) ACPI control methods.
