Hi, This is v3 of the MexTxAttrs update alongside the current state of gdbstub/next (as fixing current_cpu from gdbstub was the original motivation).
Following feedback I've drastically simplified the first patch and push the all the setting of requester_id to the per-arch tlb_fill and get_phys_page_attrs_debug helpers to fill in correctly. There is also a new patch to fix up HVF on Aarch64 which rely mostly on software modelled devices. The later re-factoring is unchanged having sailed through review without any comments. The following are left for review: - qtest: make read/write operation appear to be from CPU - target/arm: ensure HVF traps set appropriate MemTxAttrs - target/arm: enable tracking of CPU index in MemTxAttrs - hw: encode accessing CPU index in MemTxAttrs Alex Bennée (11): hw: encode accessing CPU index in MemTxAttrs target/arm: enable tracking of CPU index in MemTxAttrs target/arm: ensure HVF traps set appropriate MemTxAttrs qtest: make read/write operation appear to be from CPU hw/intc/gic: use MxTxAttrs to divine accessing CPU hw/timer: convert mptimer access to attrs to derive cpu index configure: move detected gdb to TCG's config-host.mak gdbstub: move into its own sub directory gdbstub: move sstep flags probing into AccelClass gdbstub: move breakpoint logic to accel ops gdbstub: move guest debug support check to ops configure | 7 ++ meson.build | 4 +- accel/kvm/kvm-cpus.h | 4 + gdbstub/internals.h | 17 ++++ gdbstub/trace.h | 1 + include/exec/memattrs.h | 17 +++- include/qemu/accel.h | 12 +++ include/sysemu/accel-ops.h | 7 ++ include/sysemu/cpus.h | 3 + include/sysemu/kvm.h | 20 ----- accel/accel-common.c | 10 +++ accel/kvm/kvm-accel-ops.c | 9 ++ accel/kvm/kvm-all.c | 44 +++++----- accel/stubs/kvm-stub.c | 16 ---- accel/tcg/tcg-accel-ops.c | 98 +++++++++++++++++++++ accel/tcg/tcg-all.c | 17 ++++ gdbstub.c => gdbstub/gdbstub.c | 156 ++++----------------------------- gdbstub/softmmu.c | 51 +++++++++++ gdbstub/user.c | 68 ++++++++++++++ hw/intc/arm_gic.c | 39 +++++---- hw/timer/arm_mptimer.c | 25 +++--- softmmu/cpus.c | 7 ++ softmmu/qtest.c | 26 +++--- target/arm/hvf/hvf.c | 4 +- target/arm/ptw.c | 3 + MAINTAINERS | 2 +- gdbstub/meson.build | 9 ++ gdbstub/trace-events | 29 ++++++ trace-events | 28 ------ 29 files changed, 461 insertions(+), 272 deletions(-) create mode 100644 gdbstub/internals.h create mode 100644 gdbstub/trace.h rename gdbstub.c => gdbstub/gdbstub.c (95%) create mode 100644 gdbstub/softmmu.c create mode 100644 gdbstub/user.c create mode 100644 gdbstub/meson.build create mode 100644 gdbstub/trace-events -- 2.34.1
