[9fans] sparc64 port

[9fans] sparc64 port

[Sascha Retzki]

Hi friends,


I tried out Newshams sparc64 ports today (the latest tarball), and I experienced two and a half problems.

First of, there is a file missing in /sys/src/ape/lib/9/sparc64: getcallerpc.s.
As it is a oneliner which just returns 'something' ( I failed to parse it, honestly my asm is bad ), I just copied over the sparc/getcallerpc.s. (Hit me with your cluesticks later)

That again made ghostscript (and only ghostscript) not compile, syntax errors in gdevddrw.c arround an int64_t c; .. anyway. I won't use gs on sparci right now, anyway ;)


The other major problem is that the kernel does not build. I don't know how it is supposed to work, anyway. main.c modulglobally declares FPsave initfp which is used in main.c/miscinit(): savefpregs(&initfp); but also in trap.c/fpenable(): restorefpregs(&initfp);, which is called by trapinit() (which makes me think trap.c is a 'young' module which has never been tested).


Furthermore, I had to copy pc/pcf to sparc64/sparc64f, including a lot of tweaks of course - a working default-config may have been cool :P


That's how far I got. Tim, are you still here? Any comments? Anybody looked into this more deeply? Made it work?



Mfg, Sascha

Fixed (passing some pointer arround so that trap.c knows about it, via trapinit().. good practise?)

Now it fails with:
uc -FVw devsd2.c
devsd2.c:356 not a member of struct/union: id
devsd2.c:357 not a member of struct/union: id
devsd2.c:894 not a member of struct/union: stat
devsd2.c:895 not a member of struct/union: stat
warning: devsd2.c:897 set and not used: p
mk: uc -FVw devsd2.c  : exit status=rc 1722: uc 1724: error


The four lines in question are:
		if(sdifc[i]->id)
			sdifc[i]->id(sdlist);

			if(sdev->ifc->stat)
				p = sdev->ifc->stat(sdev, p, e);

Both structures are SDifc, ../port/sd.h. There have not been id() and stat() pointers since 2003 (/n/sourcesdump/2003/0202/plan9/sys/src/9/port/sd.h has them, but 2004 doesn't). What are the alternatives? What did the old ones do, what do the new ones do differently?

Untrue. After I fixed the mkfile today (strip(1) works differently from the 2003-strip(1), as it seems :) ), I found out there are config-files. However I managed to not see them.
