Dear experts,
I am running a rv64 binary program which uses hypervisor extension v0.6.1 on
QEMU with "virt" board. The same RiscV program can run on both QEMU v6.0 and
v6.1, but it led to crash of QEMU v6.2:
```
ERROR:../..target/riscv/translate.c:232:get_gpr: code should not be reached
Bail out!
Dear experts,
I am checking a working rv64 program with hypervisor extension on QEMU v6.1 via
GDB.
While V=0 and Priv=1, I can see page table pointed by $satp from GDB.
However, while V=1, I can read $hgatp from GDB, but can't read the page table
any more:
```
(gdb) p/x $hgatp
$4 = 0x80002
Sorry that I pasted wrong session in last email, it should be
```
(gdb) p/x $hgatp
$5 = 0x80002008579a
(gdb) p/x *(uint64_t*)0x8579a000
Cannot access memory at address 0x8579a000
```
Regards,
yf

Dear experts,
With `qemu-system-arm -M virt -smp 2`, it seems that secondary core is halted
upon boot and needs be brought up via PSCI later.
I am wondering if there is a way to tell QEMU to boot all cores upon boot
without having to use PSCI? I couldn't find an option in the manual yet.

Dear experts,
I am wondering how the precision of timers are with QEMU on x64 Ubuntu Linux and
TCG accelerator?

Dear experts,
I am wondering QEMU semihosting for ARM or RISCV targets allows user to control
the set of functions available in semihosting? for example, I want give read-
only host folder share and poweroff functions to a guest. Is this possible?
Regards,
yf
