But for the other call, what do you propose?
My best try was to hide the availability of hpet inside hpet_emul.h
with:
#ifdef CONFIG_HPET
uint32_t hpet_in_legacy_mode(void);
else
uint32_t hpet_in_legacy_mode(void) { return 0;}
#endif

Hi all.
I am very new to dev for QEMU, so I have some very basic questions.
1) I understand that QEMU has a built-in GDB server that is somewhat a
simulation of a JTAG device on dev boards, connected directly to the CPU. Is

2) How can the GDB server handle a MMU? Would it

Hi, everyone.
I tried to test the qemu, but I found only qemu-i386 is tested.
But is there any test about other command like qemu-system-arm or
qemu-arm to make sure the function still work after modification?
Best Regards,
robert

I think this series conflicts a bit with Luiz's series which I just
pushed. Could you rebase against the latest?
You didn't apply this one yet, at least I don't see it on

This looks very promissing.
I just got a couple of observations:
