[Qemu-devel] Potential sparc32 MMU bug

2007-02-16 Thread Peter
While working on getting SunOS to boot under qemu, I ran into a very odd bug, and I'm not sure whose fault it is. The SunOS bootloader tries to install trap 0 by writing to the trap table. The trap table is in the .text (read-only) section of the OpenBIOS ROM. The bug is that the write to the

[Qemu-devel] Expanding the size of the vram for GDM5446?

2007-02-16 Thread Ben Taylor
I was wondering about the possibility of expanding the amount of vram for the Cirrus Logic GDM5446 emulation. 8MB of ram would give the ability to do 1600x1200 24 bit color. I know, this would probably completely break windows and other drivers, but am wondeirng if the Cirrus Xorg driver could

It definitely gets blocked by something: if I leave the the trap table in the .text section, the write silently fails. If I move the trap table to the .data section, the write succeeds. If I move the trap table over to .rodata, the write fails again. What are you looking at that suggests the

Re: [Qemu-devel] Potential sparc32 MMU bug

2007-02-16 Thread Paul Brook
I don't know about sparc, but it's normal for writes to ROM to be ignored. However by my reading the sparc bios is loaded into RAM anyway, so it shouldn't matter. It definitely gets blocked by something: if I leave the the trap table in the .text section, the write silently fails. If I

Re: [Qemu-devel] Potential sparc32 MMU bug

2007-02-16 Thread Peter
Where is the policy of silently ignoring ROM writes implemented? It may not be the proper behavior for sparc, and I'd like to tinker with it. I'm just not sure where the write is getting suppressed (or, alternatively, where the exception is getting suppressed). On 2/16/07, Paul Brook [EMAIL
