[CALL FOR TESTERS] pre-release of silo 0.7.3

[CALL FOR TESTERS] pre-release of silo 0.7.3

[Jakub Jelinek]

Hi!

I've put a pre-release of SILO 0.7.3 to
ftp://ultra.linux.cz/OS/Linux/Sparc/local/silo/testing/silo-pre0.7.3-1.tgz
I've welcome any feedback on it.
I haven't been able to test this on any 32bit SPARC, so please be careful
(make sure you have a running tftp server close to you with your kernel).

This release should remove the 2.5MB limit from sparc64 kernels by
dynamically relocating silo second stage loader if enough memory is found.
Also, I have tried to incorporate some of the changes a couple of people
wanted (I think mostly for sun4c with newer PROM).

There is still no support for sun4, although I started looking into it. I
think it is doable, but I'll need some way how to test it, know what
configurations should I support (if only SBUS based are enough, or if I need
to support VME based machines as well).

Also, this code should be compilable even with most recent linux ufs
headers, I hope both under libc5 and glibc. Tell me if I'm wrong.

Cheers,
    Jakub

Hello,

	I tested what I could from the pre-release.  My environment is a
sun4c running linux 2.1.115.

	The first problem was an undefined reference to S_ISLNK in
second/ufs.c, which is easily fixed by including <linux/stat.h> which
defines this macro, at least for 2.1.115.

	The second problem is a little more difficult, it seems that the
second/util program didn't like the files it was working with -- 

ld -N -Ttext 0x280000 -Bstatic -o second crt0.o decomp.o console.o
printf.o malloc.o jmp.o prom.o tree.o urem.o udiv.o stringops1.o bmark.o main.o

Distance between two changes larger than 64K 0 66337 11302
make: *** [second.b] Error 1
 
	I was confused, because 66337 - 11302 < 64K.  A quick glance at
util.c showed that the error message came from the save() function, line
50 (not 42, where a similar error message can be printed):

fprintf(stderr, "Distance between two changes larger than 64K %d %d %d\n", \
	type, curoff + j, lastv[type]);

I believe that the last argument should be lastv[type+1] as that value is
what is actually being compared in the if expression above the error
message. Upon making that change, util gives

Distance between two changes larger than 64K 0 66337 0 

as its error.  I was curious as to how far along util got and added
some debugging printf statements.  The first two calls to save() are
okay, the problem happens with the third call (line 115 in main()):

save (g, rodata_start - first_end, 0);

Any idea as to what could be happening here?

Hi Jakub,

I've got an Ultra 5 and SparcStation10 I could do some testing on. What
would I look for? I've got UltraPenguin1.0.9 installed on both right now
and that silo works great. Although, I never been able to boot the sun
OS with silo. Does this newest release fix that? Let me know.

Thanks Jakub,

Korey

Silo boots excelently :-), only S_ISLNK compile problem mentioned by
Kevin Milans.
