Hi,
I'm adding Sun4d support to Qemu and I was wondering if there are any
docs for Sun4d, especially interrupt handling (SBI, BW, counters, SMP
issues, boards). Any pointers?
Looking at Linux sources, it seems that SBI handles SBus interrupts
and then BW masks all interrupt sources. Is BW CPU spe

Hi,
I've tried to add support to Qemu (and OpenBIOS) for more than 4G of
memory for the Sparc32 target. But now it seems that Linux can't use
this memory after all. The first show stopper is this code in
arch/sparc/prom/memory.c:
111 /* Grrr, have to traverse the prom device tree

Thanks! So basically the virtual to physical translation can be
emulated by the following code:

Hi,
I'm trying to add Sun4c (SS-2) support to Qemu. I'm using Linux source
as the reference, but some things are not very clear.
Specifically, how are the interrupts routed, which interrupts (ZS,
ESP, Lance, timers, floppy, cgthree) go through the interrupt
controller? How do the controller bits

I don't think so, my Ultra60 installed perf
Hi,
I'm testing the Aurora CDROM on Qemu (current CVS version). The
install seems to run fine, but at start Qemu gives the following error
messages a few times:
scsi-disk: Inquiry buffer too small (4)
Maybe this message is related to esp errors?

Hi,
This version adds support for ESP SCSI controller (not the real, but Qemu
one), Type 5 keyboard, and some more escape codes. Now Qemu can boot from a
CD and one can use keyboard to select SILO options in graphical mode. I've
also merged a patch from Debian.

Where do they come from, I wonder? What part of your distro produces them?
My RHL did not print any escape sequences for colored "[ok]" on serial
console.
Linux prints the escape sequences at boot when console=prom. Proll prints
the text to graphical console (TCX, black text on white bg). Later, w
Hi,
I've added basic VT100 escape sequence processing to Proll, so that the
screen is not full of garbage at boot. The code is stolen from Linux itself.
Could someone with a real Javastation try the updated version?

It branches to "trap_setup" which is what sets
up %g6 via the LOAD_CURRENT() macro we discussed
earlier.
Thanks, I found the bug: PS flag was always equal to S, so %g6 was assumed
OK. Now we reach the userland:
RAMDISK: Loading 64KiB [1 disk] into ram disk... done.

Hi,
%g6 is loaded at "arch/sparc/kernel/etrap.S:trap_setup_from_user" by the
"LOAD_CURRENT()" macro.
Yes, I used that when patching.
At context switch time, it is updated by the switch_to() macro.
There has been no context switch yet.
At bootup, the first cpu sets up it's %g6 in arch/sparc/kernel/h
Hi,
Qemu's Sparc32 system emulator is getting to the point where the first user
space application almost executes. But there is some strangeness with
kernel's use of %g6, it's used for example in do_sparc_fault, but nothing is
restoring it before that, so there is a kernel zero page access as a
