Introduce dirty-ring-size (ranges in [1024, 65536]) option so developers can play with dirty-ring and dirty-limit feature easier. To set dirty ring size with 4096 during migration test: $ ./tests/migration/guestperf.py --dirty-ring-size 4096 xxx Signed-off-by: Hyman Huang(=E9=BB=84=E5=8B=87) Message-Id: <169073391195.19893.610675378338110324-2@git.sr.ht> --- tests/migration/guestperf/engine.py | 6 +++++- tests/migration/guestperf/hardware.py | 8 ++++++-- tests/migration/guestperf/shell.py | 6 +++++- 3 files changed, 16 insertions(+), 4 deletions(-) diff --git a/tests/migration/guestperf/engine.py b/tests/migration/guestper= f/engine.py index e69d16a62c..29ebb5011b 100644 --- a/tests/migration/guestperf/engine.py +++ b/tests/migration/guestperf/engine.py @@ -325,7 +325,6 @@ class Engine(object): cmdline =3D "'" + cmdline + "'" =20 argv =3D [ - "-accel", "kvm", "-cpu", "host", "-kernel", self._kernel, "-initrd", self._initrd, @@ -333,6 +332,11 @@ class Engine(object): "-m", str((hardware._mem * 1024) + 512), "-smp", str(hardware._cpus), ] + if hardware._dirty_ring_size: + argv.extend(["-accel", "kvm,dirty-ring-size=3D%s" % + hardware._dirty_ring_size]) + else: + argv.extend(["-accel", "kvm"]) =20 argv.extend(self._get_qemu_serial_args()) =20 diff --git a/tests/migration/guestperf/hardware.py b/tests/migration/guestp= erf/hardware.py index 3145785ffd..f779cc050b 100644 --- a/tests/migration/guestperf/hardware.py +++ b/tests/migration/guestperf/hardware.py @@ -23,7 +23,8 @@ class Hardware(object): src_cpu_bind=3DNone, src_mem_bind=3DNone, dst_cpu_bind=3DNone, dst_mem_bind=3DNone, prealloc_pages =3D False, - huge_pages=3DFalse, locked_pages=3DFalse): + huge_pages=3DFalse, locked_pages=3DFalse, + dirty_ring_size=3D0): self._cpus =3D cpus self._mem =3D mem # GiB self._src_mem_bind =3D src_mem_bind # List of NUMA nodes @@ -33,6 +34,7 @@ class Hardware(object): self._prealloc_pages =3D prealloc_pages self._huge_pages =3D huge_pages self._locked_pages =3D locked_pages + self._dirty_ring_size =3D dirty_ring_size =20 =20 def serialize(self): @@ -46,6 +48,7 @@ class Hardware(object): "prealloc_pages": self._prealloc_pages, "huge_pages": self._huge_pages, "locked_pages": self._locked_pages, + "dirty_ring_size": self._dirty_ring_size, } =20 @classmethod @@ -59,4 +62,5 @@ class Hardware(object): data["dst_mem_bind"], data["prealloc_pages"], data["huge_pages"], - data["locked_pages"]) + data["locked_pages"], + data["dirty_ring_size"]) diff --git a/tests/migration/guestperf/shell.py b/tests/migration/guestperf= /shell.py index 8a809e3dda..7d6b8cd7cf 100644 --- a/tests/migration/guestperf/shell.py +++ b/tests/migration/guestperf/shell.py @@ -60,6 +60,8 @@ class BaseShell(object): parser.add_argument("--prealloc-pages", dest=3D"prealloc_pages", d= efault=3DFalse) parser.add_argument("--huge-pages", dest=3D"huge_pages", default= =3DFalse) parser.add_argument("--locked-pages", dest=3D"locked_pages", defau= lt=3DFalse) + parser.add_argument("--dirty-ring-size", dest=3D"dirty_ring_size", + default=3D0, type=3Dint) =20 self._parser =3D parser =20 @@ -89,7 +91,9 @@ class BaseShell(object): =20 locked_pages=3Dargs.locked_pages, huge_pages=3Dargs.huge_pages, - prealloc_pages=3Dargs.prealloc_pages) + prealloc_pages=3Dargs.prealloc_pages, + + dirty_ring_size=3Dargs.dirty_ring_size) =20 =20 class Shell(BaseShell): --=20 2.38.5
