- Say Y if you want to enable SmartReflex.
-
- SmartReflex can perform continuous dynamic voltage
- scaling around the nominal operating point voltage
- according to silicon characteristics and operating
- conditions. Enabling SmartReflex reduces power
- consumption.
+ Say Y to enable AVS(Adaptive Voltage Scaling)
+ support on OMAP containing the version 1 or
+ version 2 of the SmartReflex IP.
+ V1 is the 65nm version used in OMAP3430.
+ V2 is the update for the 45nm version of the IP used in OMAP3630
+ and OMAP4430
Please note, that by default SmartReflex is only
- initialized. To enable the automatic voltage
- compensation for vdd mpu and vdd core from user space,
+ initialized and not enabled. To enable the automatic voltage
+ compensation for vdd mpu and vdd core from user space,
user must write 1 to
- /debug/voltage/vdd_<X>/smartreflex/autocomp,
- where X is mpu or core for OMAP3.
+ /debug/smartreflex/sr_<X>/autocomp,
+ where X is mpu_iva or core for OMAP3.
Optionally autocompensation can be enabled in the kernel
by default during system init via the enable_on_init flag
which an be passed as platform data to the smartreflex driver.
