I tried to get the sysctls more in line with our other ACPI extras drivers,= =20 which all reside under hw.acpi.<brand> and hence the rename of e.g.=20 brightness->lcd_brightness and the relocation of the tree.

Writing to the EC directly is nothing more that accessing the locations via= =20 acpi_SetInteger. While I would highly prefer the latter method, the problem= =20 is, that several places of the EC in the DSDT aren't even named or only=20 named on some models. Consider e.g. setting volume and mute. Here is a=20 snippet of a T41p DSDT: Device (EC) { [...] OperationRegion (ECOR, EmbeddedControl, 0x00, 0x0100) Field (ECOR, ByteAcc, NoLock, Preserve) { HDBM, 1, , 1, , 1, [...] HFSP, 8, , 6, <-- Volume HMUT, 1, <-- Mute Offset (0x31), HBRV, 8, <-- Brightness HWPM, 1, Volume doesn't have a name on any Thinkpad I have seen so far, Mute and=20 Brightness only on some. But the offset for directly accessing the EC is=20 always the same. > > led(4) interface for the thinklight (thanks simon) > > support for reading the fan status and speed > > support for reading up to 8 thermal sensors > > Works great.
