* Avoid address_space_rw() with a constant is_write argumentPeter Maydell2020-02-202-10/+9Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address_space_rw() function allows either reads or writes depending on the is_write argument passed to it; this is useful when the direction of the access is determined programmatically (as for instance when handling the KVM_EXIT_MMIO exit reason). Under the hood it just calls either address_space_write() or address_space_read_full(). We also use it a lot with a constant is_write argument, though, which has two issues: * when reading "address_space_rw(..., 1)" this is less immediately clear to the reader as being a write than "address_space_write(...)" * calling address_space_rw() bypasses the optimization in address_space_read() that fast-paths reads of a fixed length This commit was produced with the included Coccinelle script scripts/coccinelle/exec_rw_const.cocci.

* sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster2019-08-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

* target/i386: kvm: Add support for KVM_CAP_EXCEPTION_PAYLOADLiran Alon2019-06-212-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Kernel commit c4f55198c7c2 ("kvm: x86: Introduce KVM_CAP_EXCEPTION_PAYLOAD") introduced a new KVM capability which allows userspace to correctly distinguish between pending and injected exceptions. This distinguish is important in case of nested virtualization scenarios because a L2 pending exception can still be intercepted by the L1 hypervisor while a L2 injected exception cannot. Furthermore, when an exception is attempted to be injected by QEMU, QEMU should specify the exception payload (CR2 in case of #PF or DR6 in case of #DB) instead of having the payload already delivered in the respective vCPU register. Because in case exception is injected to L2 guest and is intercepted by L1 hypervisor, then payload needs to be reported to L1 intercept (VMExit handler) while still preserving respective vCPU register unchanged. This commit adds support for QEMU to properly utilise this new KVM capability (KVM_CAP_EXCEPTION_PAYLOAD).
