Message

Juergen Gross Sept. 4, 2019, 1:46 p.m. UTC

Another debugtrace enhancement I needed for core scheduling debugging,
plus some cleanup.

Changes in V4:
- replaced patch 1 (original one was committed, new one requested by
  Jan Beulich)
- several comments by Jan addressed

Changes in V3:
- rebase to current staging

Changes in V2:
- added new patch 1 (preparing the move of debugtrace coding)
- patch 4 (v1 patch 3): avoid leaking buffer

Juergen Gross (4):
  xen: fix debugtrace clearing
  xen: move debugtrace coding to common/debugtrace.c
  xen: refactor debugtrace data
  xen: add per-cpu buffer option to debugtrace
