This also avoid hardcoding the IRQ callback in the OpenPIC controller, making it more easily reusable and allowing cascading.

[Qemu-devel] [SPARC] Looking for SuperSPARC User's Guide
I've been searching high and low for the SuperSPARC User's Guide. At one time it was published as Sun part number 801-4272-01 and TI part number 2647726-9761. A previous TI version was apparently published as SPKU005 (and possibly 2647726-9721, although that could be a typo). Sun and TI don't seem to have it any more. Has anyone here been able to track down a copy? Ironically, this message will probably simply add to the few extant references to this document on the Internet, all of which are searching in vain. (I found the SuperSPARC II Addendum, but it just documents the differences between the SuperSPARC I and II. It doesn't provide a full description of the processor.)

[Qemu-devel] [PATCH] add a simple 24mhz clock for the versatile
This patch implements a simple 24mhz clock for the versatile board such
that functions in the linux kernel can make use of these stamps. An
example user of this is the printk time stamps when using the time
parameter on the kernel boot line.

[Qemu-devel] [SPARC][PATCH] Generate cp_disabled trap for Cpop instructions
Hi all,
Both of the SPARC CPU currently emulated in QEMU do not have a
coprocessor. In such case executing a Cpop1 or a Cpop2 instruction
should generate a cp_disabled trap, but the current implementation
generates a illegal_instruction instead.
The patch below fixes that.
Bye,
Aurelien

[Qemu-devel] PATCH: Solaris kqemu.c
This patch further isolates the functions needed for kqemu.c by Solaris. The original include has the unintended side effect of screwing up the mips targets on Solaris 9/x86 because there are some defines that get included via sys/modctl.h that change how the CPU structure in the mips-target/cpu.h file is processed. (Bascially, the PC variable name gets changed to 14, which completely botches the compile). Kudos to Juergen Keil for another smart fix. qemu-kqemu.c-diff Description: Binary data

RE: [Qemu-devel] [PATCH] add a simple 24mhz clock for the versatile
uint64_t now = qemu_get_clock(vm_clock); return (uint32_t)((now*3)/125); The optimizer should fix this up with no floating point ops. Jason.

Of course, you'll only get 23.4Mhz that way :-) jonathan On 3/30/07, Paul Brook [EMAIL PROTECTED] wrote: + uint64_t now = qemu_get_clock(vm_clock); + return (uint32_t)(now*.024); We should be able to do this without resorting to floating point arithmetic.

Adding to the bikeshed discussion (www.bikeshed.com) this is still not correct as vm_clock is to be used with ticks_per_sec. return muldiv64(qemu_get_clock(vm_clock), 2400, ticks_per_sec); Regards, Andrzej
