[PATCH v3 00/15] gdbstub/next (MemTxAttrs, re-factoring)

[Alex Bennée]

Hi,

Following feedback on the MemTxAttrs updates we now:

  - move unspecified to requester_type
  - document a machine specific decoding of requester_id
  - update the existing users
  - update HVF/KVM/m-profile/page-walking access functions
  - fail with MEMTX_ACCESS_ERROR if non-CPU accesses GIC

I suspect this will be my last run at this for a while so if it is
still wanting I'll split off the re-factoring work for a PR so it is
not held up. The following still need review:

 - accel/kvm: move kvm_update_guest_debug to inline stub
 - qtest: make read/write operation appear to be from CPU
 - target/arm: ensure m-profile helpers set appropriate MemTxAttrs
 - target/arm: ensure ptw accesses set appropriate MemTxAttrs
 - target/arm: ensure KVM traps set appropriate MemTxAttrs
 - target/arm: ensure HVF traps set appropriate MemTxAttrs
 - target/arm: ensure TCG IO accesses set appropriate MemTxAttrs
 - hw: encode accessing CPU index in MemTxAttrs


Alex Bennée (15):
  hw: encode accessing CPU index in MemTxAttrs
  target/arm: ensure TCG IO accesses set appropriate MemTxAttrs
  target/arm: ensure HVF traps set appropriate MemTxAttrs
  target/arm: ensure KVM traps set appropriate MemTxAttrs
  target/arm: ensure ptw accesses set appropriate MemTxAttrs
  target/arm: ensure m-profile helpers 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
  accel/kvm: move kvm_update_guest_debug to inline stub
