------- Comment #11 from [email protected] 2007-08-22 17:51 ------- acpi-cpufreq works on the system at hand,
and so I advocate that this sighting be closed as WILL_NOT_FIX.

Nobody is maintaining speedstep-centrino, and I do not advocate that it be enhanced.

------- Comment #12 from [email protected] 2007-10-18 13:01 ------- I have laptop (MAxdata 8100X) with dothan 1.6GHz and no luck - both speedstep-centrino and acpi-cpufreq (kernel 2.6.22 from gutsy). So there are STILL some old laptops with are in need for hardcoded freq tables (everyting was working on old ubuntu kernels with were pathed this way). Please don't ignore old machines...

------- Comment #13 from [email protected] 2007-10-18 13:44 ------- I asked davej about this and he said:

The only safe way to use scaling on 'dothan' cores is with ACPI. We just have no way to tell which of the four sets of voltages is in use. People keep proposing patches to hardcode a set of tables for them which "works for them", but could do *anything* on someone elses system.
Even if we added it as a CONFIG option, I'm worried that people will turn it on not understanding the consequences
and either plague us with crappy bug reports of flaky kernels (or worse). (And you guarantee some distros will turn it on to
"make hardware 'just work'")

All-round crappy situation really, we're between a rock and a hard place, and ACPI is the best hope we've got.

Thanks.

------- Comment #17 from [email protected] 2008-04-18 01:23 ------- Hello,
since i have upgraded my notebook with a latest beta of available bios,
everything started to work. From then, also acpi_cpufreq works. I think we would need info from someone whos bios still does not handle the CPU correctly. I am sorry, I can not post more relevant results.

Thanks a lot,
Oldrich Plchot
