Agreed; we already have one nasty set of bugs in the framebuffer devices because a function drops the BQL briefly: https://lore.kernel.org/qemu-devel/CAFEAcA9odnPo2LPip295Uztri7JfoVnQbkJ=wn+k8dqneb_...@mail.gmail.com/T/#u so let's avoid introducing any more of a similar kind. Side note, the pause_all_vcpus()/resume_all_vcpus() calls in hw/i386/vapic.c are probably a bit suspect for similar reasons. -- PMM
