Thanks Alex.
I am trying to understanding the generated code for the x86 target. On
EPILOGUE code below:
0x7fff9800: 55 pushq%rbp
0x7fff9801: 53 pushq%rbx
0x7fff9802: 41 54pushq%r12

Got it working. I can see the
Ah I had my .tlb_fill callback set to an empty function with just

Hi,
Some background: I am trying to write a CPU emulator for MSP430 with
Qemu. I am loading the MSP430 program as follows using the generic
device loader:
/qemu-system-msp430 -machine msp430-launchpad -device
loader,file=simple_test -d in_asm,out_asm
I have implemented somewhat the TranslatorOps

Hi,
I am going through some translation code for existing targets.
I would like to know if there are any good resources on deeper
understanding of translation blocks? Also some advice on the best way
to read code related to translation in Qemu and trying it out maybe
using the debugger, printing

I should be using the -bios switch for loading the bare metal firmware, correct?

I am trying to emulate the TI MSP430 microcontroller.

Hi,
I am to implement a very simple microcontroller for my understanding
of Qemu development. This microcontroller runs its code from
programmable flash which is bit-, byte- and word addressable. To do
some initial tests of my nascent microcontroller implementation I
would like to load a very simp

Hi,
I am confused with the usage of PCI bus for connecting different
peripherals. If I want to emulate an ARM board which doesn't have a
PCI controller how can I emulate it to be as close to the real board
as possible? Is there an ARM interconnect or something where I can
connect the peripheral co
Hi All,
I am interested in knowing what are the pain points in using Qemu as a
Software Virtual Development Platform from not only CPU perspective but a
complete PCB (CPU + different peripherals).
In most of the engineering firms that I have worked at, the PCB board was
the problem. There would e
Hi,
I want to add some I2C based temperature sensors to the -M Q35 machine. I
want to update the ACPI tables to add this device information. How can I go
about doing this?
Thanks,
Gautam.
