What I should have said was 'anyone running Linux in LE mode on ppc'. But that's also very interesting that you're running mcos in LE mode. I'm really curious as to why.. because PCI is little endian maybe?

RE: IBM PPC 405 series little endian?
I don't know why you want to run the 405 in LE... but one feature that comes in handy for me is mapping pages as LE, even though the CPU is running in BE... this might be what you're looking for. felix -Original Message- From: Troy Benjegerdes [mailto:[EMAIL PROTECTED]] Sent: Monday, June 11, 2001 11:40 AM To: Zehetbauer Thomas Cc: '[EMAIL PROTECTED]' Subject: Re: IBM PPC 405 series little endian?

Well, first, I have to ask, why?? First, if you need to deal with little endian data, on a PPC stwbrx & lwbrx are your friends.

Somebody at Matrox posted a patch for little-endian on the 74xx. You need a bit more than that though; you need to change the way page table bits get set and modify head_4xx.S IIRC. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
