Mac-On-Linux

[Alan B. <al...@ms...>]

hi,

well, an interesting Sunday...I've changed all of the kernel files that
required changes for MOL. Anyhow, the arch/ppc/kernel/head.S required
around 9 more changes to bring it in line with the official MOL patches.

the kernel compiles, but I just get a reset when I try booting into it.
frustrating! So, cant CVS submit it yet! ;-)

So, since I'm a little bit of a newbie at all this, I've put the head.S
file at the following location

http://ftfir.mols.sussex.ac.uk/linuxppc

If you download this (or take an online look at it) search for "MOL"
within the file. You'll find the MOL changes in around 10 places.
I cant see where it is failing. I'm *guessing* its the part which says

/*
 * Mac-On-Linux hook_table. Don`t put these in the data section -
 * it must be present in the first 16k of physical memory.
 */
#ifdef CONFIG_MOL
        .globl mol_interface
mol_interface:  
        .long   0x1     /* MOL interface version */
        .fill   16,4,0  /* space for 16 hooks    */
#endif

now, since on APUS we have lots of reserved memory blocks and
non-cachables, cachables, hacks, patches, ChipRAM, FastRAM, Z2_RAM etc I
think this part screws up. certainly I cant easily see why any of the
other parts would...your mileage may vary, I guess a couple of you will
see some part that will cause you to run kicking and screaming from the
VDU at what its trying to do in certain places  8-)

any help will be appreciated, I believe we're 95% to getting MOL on APUS.

PS great news on the Symbios 770 driver for the CSPPC, thats a lot of
progress made with that one now!!

Soon we'll be able to look at the USB issue on Linux, oh wait...we dont
have to! ;-)
