Doubt about powerpc7447a

Is it possible to change operating speed of powerpc7447a processor?can we configure it? I m not asking if this can be done in linux. I m asking if the hardware has some support for this.If yes,then how? -sumedh ___ Linuxppc-dev mailing list Linuxppc-dev@

I found out the problem...it was somewhere in my code...actually the link register was getting over-written... Thanks for help... Regards, Sumedh On Tue, Feb 24, 2009 at 5:23 PM, sumedh tirodkar wrote: > The reason that i m using bla is that i am writing the interrupt > handler from dec

Problem with decrementer interrupt

In the handler for decrementer interrupt...there is a call to a C function... Now if the call is removed...the decrementer interrupt works perfectly fine... But if the C function is present, then the decrementer interrupt stops coming after say 5-6 times... Not able to find any reasoning for the sa

PowerPC 7447A Paging table Search

How will i confirm if PowerPC 7447A processor has or does not have a dedicated hardware for page table search algorithm? If it does not have, then which interrupt handler is written for page address translation mechanism? -Sumedh ___ Linuxppc-dev mailin

hash-table creation...

Hello, I wanted algorithm for creating hash tables used in paging mechanism.. In the manual that i read i got algorithm to convert Effective Address to Real Address using these hash tables that are created..but i could not find how these hash tables are created in first place using the Real addres

Re: yaboot: text mode or graphics mode?

Isn't there any other way that i can access the VGA registers? So as to reconfigure them... -Sumedh On Wed, Dec 31, 2008 at 4:15 AM, Matt Sealey wrote: > sumedh tirodkar wrote: >> >> I just found out that openfirmware boots into graphics mode(non-text >> mode). Now i w
