[PATCH 00/10] tracing: remove dynamic vcpu state |
Date: |

The references dynamic vcpu tracing support was removed when the
original TCG trace points where removed. However there was still a
legacy of dynamic trace state to track this in cpu.h and extra hash
variables to track TBs. While the removed vcpu tracepoints are not in
generated code (or helpers) they still bring in a bunch of machinery
to manage the state so I've pulled them out. We could just replace
them with static trace points which dump vcpu->index as one of their
arguments because they don't happen that often.
While most of the changes are excising bits of the tracing code I've
also cleaned up the xxhash function use and simplified the core
function to qemu_xxhash6.
Please review.
Alex Bennée (10):
*-user: remove the guest_user_syscall tracepoints
trace-events: remove the remaining vcpu trace events
trace: remove vcpu_id from the TraceEvent structure
scripts/qapi: document the tool that generated the file
qapi: make the vcpu parameters deprecated for 8.1
trace: remove code that depends on setting vcpu
trace: remove control-vcpu.h
tcg: remove the final vestiges of dstate
hw/9pfs: use qemu_xxhash4
xxhash: remove qemu_xxhash7
