Subject: [PATCH] allow the highest frequency if bios think so.
Date: Tue, 21 Nov 2006 11:30:42 +0100 [thread overview]
Message-ID: <20061121103042.GI4945@poupinou.org> (raw)
Hi all,
processor_perflib.c::acpi_processor_ppc_notifier() check if the value
returned by the processor's _PPC method is 0 and return failed if so.
This is wrong since 0 indicate that the bios think the processor can go
to the highest frequency. This patch for example fix the HP NX 6125 to
allow its highest frequency to be available.
