Improvements in our ACPI device matching code led to the question of what devices are out there we might match and add drivers for. The catch is that there are devices that we have drivers for but which we don't match that driver to device by the HID. In that case, the kernel may emit a "not configured" message even though the underlying device really is configured and used just fine. Adding those to the acpi_skip_hids[] array in acpi.c would quiet some of the noise. For example: > "PNP0400" at acpi0 not configured This is lpt0 at isa0 port 0x378/4 irq 7 > "PNP0501" at acpi0 not configured com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo > "PNP0501" at acpi0 not configured com1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo > "MSFT0001" at acpi0 not configured The "irq 1" part of: pckbc0 at isa0 port 0x60/5 irq 1 irq 12 > "MSFT0003" at acpi0 not configured pms0 at pckbc0 (aux slot) > "BCM2E64" at acpi0 not configured Antenna control button? > "BCM4752" at acpi0 not configured GPS receiver? > "SMO91D0" at acpi0 not configured A sensor hub? > "INTCF1C" at acpi0 not configured The camera, or something related to it? > "MSFT0002" at acpi0 not configured i2c bus? > "PNP0C0B" at acpi0 not configured Fan. Probably handled indirectly via acpitz0. So, looks like the first five can be ignored (and we should perhaps add to the skip_hids table) but at least a couple of the others might be interesting for targets for devices...for someone with the hardware... > acpicpu0 at acpi0 > C2: state 6: substate 8 >= num 3 > C3: state 7: substate 4 >= num 3: C1(1000@1 mwait.1), PSS > acpicpu1 at acpi0 > C2: state 6: substate 8 >= num 3 > C3: state 7: substate 4 >= num 3: C1(1000@1 mwait.1), PSS > acpicpu2 at acpi0 > C2: state 6: substate 8 >= num 3 > C3: state 7: substate 4 >= num 3: C1(1000@1 mwait.1), PSS > acpicpu3 at acpi0 > C2: state 6: substate 8 >= num 3 > C3: state 7: substate 4 >= num 3: C1(1000@1 mwait.1), PSS Harumph. Can you install the "cpuid" package and show the output of "cpuid 5"? Run as a normal user should be fine. Philip Guenther
