acpi_processor_get_per: Unsupported address space

acpi_processor_get_per: Unsupported address space

[Jan Rychter]

On a Toshiba Dynabook SS S7/290LNKW (Centrino-based), kernel 2.4.22-pre7
(also tested with pre5).

I am getting the following message at bootup:

acpi_processor-0899 [31] acpi_processor_get_per: Unsupported address space [127] (control_register)
ACPI: Processor [CPU0] (supports C1 C2 C3)
ACPI: Thermal Zone [THRM] (44 C)

What does this mean? Does it indicate problems?

It means that the "performance states" == SpeedStep states are only
available using the binary-only processor.o replacement module available at
Intel's ACPI site, or using the cpufreq speedstep-centrino module [patches
in 2.5., or at http://www.codemonkey.org.uk/cpufreq/ once davej's server is
back online]

Dave's server is still down, it seems. Is there a 2.4 port of these
drivers? I don't think I'm ready for 2.5 yet, having just achieved a
stable 2.4 kernel on my laptop, which took about 1.5 years.

The binary-only driver is for 2.4.21-rc1 only, so it's of no use to me
(I have 2.4.22-pre7 and have to follow the -pre series because of USB
bugs).

I have to say I feel kind of silly playing this hide and seek game with
Intel. On one hand Intel says they support Linux
(http://news.com.com/2100-1006-993896.html). On the other hand we get no
support for speedstep (what on earth do you lose by telling people how
to program your hardware?), no support for Centrino wireless LAN. I find
it both ridiculous and sad.

I can live with it :).
