I'm sponsoring this case for Bill Yan. This project is to add the CPU,
Memory and Battery categories to the OpenSolaris Device Drive Utility
tool so that users could get information on these devices easily. A
Micro release binding is proposed.
I have marked it as "closed approved automatic" since the change is
straightforward and the interface is clear. If there is request, I'd be
happy to upgrade it to a fast track and set the timer.

4. Technical Description
4.1 Summary
The intent of this project is to add CPU, Memory and battery category to
the OpenSolaris Device Driver Utility Tool.
Requested release binding is Micro.
4.2 Details
This project propose to add the following information to the Device
Driver
Utility tool [1].
* CPU information: including CPU type, number of CPU, number of
cores per
processor and number of threads per processor.
* Memory information: including amount of physical memory, maximum
memory
supported and detail information of each memory device/module (size,
type,
speed, bit-width).
* Battery information: including model, serial, vendor, technology,
charge/discharge status, design charge level, current charge level,
design
voltage, current voltage, charge percentage and estimated remaining
time (if
battery is discharging).
On i86pc platform, CPU information is fetched through CPUID
instruction and
SMBIOS, memory information is got from SMBIOS, battery information
is got
from HAL. On sparc platform, libpicl is used to fetch CPU and memory
information. Battery information is not provided on sparc platform.
