Re: [ACPI] [PATCH, new ACPI driver] new sony_acpi driver
platform specific wart is the only way to go. But it would be best if we can make the exotic Sony/SNC look more generic to the user so that the user (and the distro supporting them) don't need to learn special things to handle this system. I agree, but unfortunately I don't think it's possible to handle them in a generic way. However, my understanding of the ACPI layer is limited, so I very well be wrong. I attached two DSDT in bugzilla, I have a few more if you want them. I will (re)work some part of the acpi_video stuff in order to make it more generic (its design is to separate a kind of 'video bus', then 'video devices' can attach. For now, its support only one kind of device, the acpi one. See acpi_viedo.c). The original goal was to atleast attach others acpi specific drivers (the toshiba at that time).
