[PATCH v4 0/6] tests/qemu: Add program for tracing and analyzing boot times.
v4:
- Lots more analysis of the /init script and other parts.
- Display a list of the longest to shortest activities.
- Rebase on top of current head.

[PATCH v2 00/21] drm: Clean up VBLANK callbacks in struct drm_driver
VBLANK handlers in struct drm_driver are deprecated. Only legacy,
non-KMS drivers are supposed to used them. DRM drivers with kernel
modesetting are supposed to use VBLANK callbacks of the CRTC
infrastructure.
This patchset converts all DRM drivers to CRTC VBLANK callbacks and
cleans up struct drm_driver. The remaining VBLANK callbacks in struct
drm_driver are only used by legacy drivers.

[PATCH v3 0/11] tests/qemu: Add program for tracing and analyzing boot times.
Lots of changes since v2, too much to remember or summarize.
Please ignore patch 11/11, it's just for my testing.

[PATCH v2 0/7] tests/qemu: Add program for tracing and analyzing boot times.
v1 was here:
https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157
Not running the 'hwclock' command reduces boot times considerably.
However I'm not sure if it is safe. See the question I posted on
qemu-devel:
http://thread.gmane.org/gmane.comp.emulators.qemu/402194
At the moment, about 50% of the time is consumed by SeaBIOS. Of this,
about ⅓rd is SGABIOS
