Tracing the state of the voltage and current regulators enables a developer
to attribute power consumption measurements to specific perhipherals and
cores. Unlike other indirect methods of tracing when peripherals and cores
are toggled, the regulator ftrace event indicates the exact point in time
when the kernel switches on or off the device. For example, in the following
trace, a developer can see exactly when the krait2 core starts receiving
power, and and when the voltage is set for voltage scaling.

Some time before kitkat, a workaround was put in place to keep tuna
working with obsolete PowerVR GPU drivers. The tuna product was dropped
in AOSP for kitkat, but the workaround remained.
There are still a number of devices shipping with OMAP4 processors, and
this workaround continues to be applied on those products even when it
is not required. The effect is that virtual display CTS will fail on
those devices.
This option doesn't work with the current selinux protections and
doesn't serve much of a purpose. You can get the same results running
this:

This seems to have the same layout as OMX_COLOR_FormatYUV420SemiPlanar,
but used under this value on some devices.

Fix regression from 6701fbe5f0 .
The rdhwr instruction is unsupported by mips32r1 cpus, but is
supported via kernel emulation on those cpus.
