[parisc-linux] Xfree-server and Xhp ?

[Joel Soete]

Hi all,

I just discover some days ago (when trying to rebuild 4.3) that in XFree-4.2 still exists (not anymore
in 4.3?) the sources of a Xhp server supporting the builtin gfx of my testing b180 (into build-tree/xc/programs/Xserver/hw/hp/).

Juliusz Chroboczek <jch@pps.jussieu.fr <mailto:jch@pps.jussieu.fr>> kindly explain me:

It doesn't build :-(

But I also found some additional patch which HP supplied for suport of X11R6.3 into mklinux project.
It would be helpful as this patch supplied (among other things) the asm src of an object supplying requested ngleDepth8_CopyAreaFromToScreen() and ngleDepth24_CopyAreaFromToScreen() functions.
Into mklinux sources I also find back <machine/asm.h> it would be easy with the help of kernel documentation to 'reverse' it for parisc linux (seems to be trivial).
My only pb is that src seems to be writen for 'som' env:

(arg[0..3], r[0..], t[1..4] beeing labels defined <machine/asm.h>)

Does it exist some doc or tips to do this kind of obj translation 'som' -> 'elf'?

Thanks in advance for advises,
