[Qemu-devel] Sparc patch 16

[Blue Swirl]

Hi,

What's new:
* Serial ports updated. With a suitably enhanced Proll (not included, too 
ugly) you can use the serial ports for prom console.
* Interrupt controller and timer updated, it should be trivial to add 
support for max. 16 CPUs.
* There is a bug in bypass load and store instructions: if -nographic flag 
is set, the cpu_physical_memory_set_dirty etc. can corrupt memory. We would 
need something between ldl/stl_raw and ldl/stl_kernel that bypasses the MMU 
entirely but still can use memory-mapped I/O. Fabrice?
* Gave a shot at linux-user for sparc. Signals cause the handler to be 
called. On return from handler, the trampoline put to stack by qemu is 
executed, causing a sigreturn system call. Even that works (the registers 
are same as before the signal), but when the glibc function raising the 
signal in the first place returns, the CPU wants to jump to trampoline 
again.

Fabrice, it would be nice to get the most of this merged so that the patch 
doesn't get too large. I can split it or whatever, if you give me some 
direction.
