To limit a CPU to a certain C-state, you can pass the processor.max_cstate=X
option in the kernel
line of /boot/grub/grub.conf
.
Here we limit the system to only C-State 1:
kernel /vmlinuz-2.6.18-371.1.2.el5 ... processor.max_cstate=1
On some systems, the kernel can override the BIOS setting, and the parameter intel_idle.max_cstate=0
may be required to ensure sleep states are not entered:

First of all: YUV pixel formats and Recommended 8-Bit YUV Formats for Video Rendering. Chromium's source code contains good documentation about those formats too: chromium/src/media/base/video_types.h and chromium/src/media/base/video_frame.cc (search for RequiresEvenSizeAllocation()
, NumPlanes()
and those kinds of functions).
You can think of an image as a superposition of several planes (or layers in a more natural language). YUV formats have three planes: Y
, U
, and V
.
Y
is the luma plane, and can be seen as the image as grayscale. U
and V
are reffered to as the chroma planes, which are basically the colours. All the YUV formats have these three planes, and differ by the different orderings of them.
