[Qemu-devel] [PATCH] Fix udp slirp to always set from address and port
Attached is a patch to always set the from address and port when using slirp "-net user" type networking. It fixes the case so that the target can boot from udp NFS as well as the case where different instances of an application over time go through the same redirection port with different source ports or addresses. A possible approach for the future if advanced use cases are required is to allow specification of 3 different categories of redirection access. 1) Dynamic port and address (the default with this patch) 2) Dynamic port with static address 3) Dynamic address with static port 4) static port and address The last 3 would mainly be for security type options if you wanted to restrict things. Items 2-4 can go into a ToDo list somewhere. signed-off-by: [EMAIL PROTECTED] Jason.

Maybe I'm totally wrong, but env->pc is set some times to the same value again and again. And other debug output indicates, that sometimes a portion of code containing an FPU instruction is executed more than one time. Hence, it looks like the pc is always set to the pc of the tb, and not to the pc of the interrupted function. If the tb ands with the interrupted function this does not seem to be a problem, but in case of FPU interrupts it may be raised everywhere...

A "save_state(dc);" call was missing before all invocations of "gen_op_trap_ifnofpu();" in translate.c.

RE: RE: [Qemu-devel] [PATCH 1/5] single step with no IRQs and timers
The single stepping actually only gets turned off if you do: Qqemu.sstep=0 I am guessing you probably don't want to do this. But as with anything there are reasons you might, such as debugging internals of QEMU. The bit is in there for future use more than anything, and to maintain compatibility with what is out there.

Re: [Qemu-devel] [PATCH 1/5] single step with no IRQs and timers
Hi, I agree that the feature is useful, but I am not sure yet if I will apply as is. I am adding support in QEMU for deterministic execution and your patch won't be needed once this new feature is released. BTW, why do you stop real time timers ? These timers are only used for things which do not interfere with the VM (such as VGA refresh). Fabrice. Jason Wessel wrote: This patch adds the functionality to the gdb-stub to single step with the IRQs and timers disabled. It greatly improves gdb's ability to perform run control while running a linux kernel and stepping off of breakpoints or stepping into certain types of functions. I have also included individual controls for IRQs and timers to restore the original behavior, since it is useful as well. signed-off-by: [EMAIL PROTECTED] Jason. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

RE: [Qemu-devel] [PATCH 1/5] single step with no IRQs and timers
Fabrice, I will defer to you on the real time timers. I had not examined the code thoroughly enough to understand if there was more to the real time timers. I had wanted to guard against any kind of interrupts or triggers that might fire off. Just call it a lack of total understanding of the complete QEMU infrastructure. I would say the real time timers can run if you feel the dependencies for precise single instruction execution are not violated. I found gdb against a linux kernel to be next to useless for any real run control debugging with out the patch. Deterministic execution sounds great. I would be happy to add debugger hook controls to further control it at runtime with GDB, if your deterministic execution controls are not already there at time. I have found QEMU to be very useful for the analysis of strange run control issues which is where the patch came from in the first place. Just let me know if you want me to re-gen the patch or if it will ultimately go to the bit bucket in favor of something better. It is a great stopgap in the in mean time.

Hi!
Here is a patch fixing the problem by calling save_state before all possible
