[Qemu-devel] [PATCH 2/2] target/i386/monitor.c: check return value of mon_get_cpu before using it

From: Ziyue Yang This patch eliminates the segfault caused by accessing CPU that doesn't exist in hmp command "info lapic", which can be reproduced by $ qemu-system-x86_64 -nographic -M none -serial none -monitor stdio and then type "info lapic" into qemu monitor.

[Qemu-devel] [PATCH 1/2] monitor.c: make mon_get_cpu return NULL when there is no CPU

From: Ziyue Yang Currently mon_get_cpu always dereferences first_cpu without checking whether it's a valid pointer. This commit adds check before dereferencing, and reports "No CPU" info if there isn't any CPU then returns NULL. Signed-off-by: Ziyue Yang --- monitor.c | 1

[Qemu-devel] [PATCH 0/2] fix segfaults caused by accessing CPU in empty machine

From: Ziyue Yang Many QEMU monitor commands, like "info lapic", "info tlb" and so on use mon_get_cpu or related wrappers to access CPU info without checking whether the CPU exists. This patch series fix the "info lapic" case, and is the base of the incoming pa

[Qemu-devel] [Bug 1641637] Re: incorrect illegal SSE3 instructions reporting on x86_64

Hi Jie, Seems that the problem was caused by not specifying the cpu model when running QEMU. when running qemu-x86_64 ./28 QEMU would recognize the cpu model as "qemu64", which act like a cpu doesn't support advanced instruction sets like SSSE3. To workaround, you can run qemu-x86_86 -cpu core2
