Title:
"accel/tcg: demacro cputlb" break qemu-system-x86_64 on 32-bit x86
host
Status in QEMU:
In Progress
Bug description:
As described in https://lists.gnu.org/archive/html/qemu-
devel//2019-05/msg07362.html I run into TCG regression in qemu-git.
Unfortunately, fix from bug
https://bugs.launchpad.net/qemu/+bug/1830872 seems to be nonn-
effective for my case.
For reproduction (on 32-bit x86 host, in my case Slackware with gcc
5.5.0):
./configure --target-list=x86_64-softmmu --disable-werror --enable-
debug-tcg
make (-j5 in my case)
try to boot any 64-bit kernel:
x86_64-softmmu/qemu-system-x86_64 -kernel /boot/bzImage-4.12.0-x64
-accel tcg
result is - qemu appear to hang right after "Booting the kernel" line.
Decompression (xz) was ok.
Tested with qemu-git commit e2a58ff493a2e00db3e963c1839c5374500110f2
32-bit OS can be booted fine, and -enable-kvm also allow 64 bit
kernel/os to boot.
