Re: ACPI OSI disaster on latest HP laptops - critical temperatureshutdown

[Len Brown]

Thomas,

re: OSI(Windows...)

Linux will continue to claim OSI compatibility with Windows
until the day when the majority of Linux systems
have passed a Linux compatibility test rather than
a Windows compatibility test.

Re: OSI(Linux)

I've looked at O(100) DSDT's that look at OSI(Linux),
and all but serveral systems from two vendors do it by mistake.
They simply copied it from the bugged Intel reference code.

OSI(Linux) will _never_ be restored to Linux, ever.

re: the HP BIOS bug at hand.

Linux deletes the entire thermal zone when we see this.
(arguably, we could have just disabled the CRT
and kept the rest of the thermal zone).
If HP cared about testing Linux on this laptop
and had tools such that they could actually
test Linux compatiblity, it would be pretty clear
from user-space that their thermal zone was missing.

thanks,
-Len
