119 of hardware components aggregate requests for these resources and
120 help apply the aggregated state on the resource.
123 tristate "Qualcomm RPMh Power domain driver"
124 depends on QCOM_RPMH && QCOM_COMMAND_DB
126 QCOM RPMh Power domain driver to support power-domains with
127 performance states. The driver communicates a performance state
128 value to RPMh which then translates it into corresponding voltage
129 for the voltage rail.

234 ASM, ADM and AFE modules.
236 config QCOM_ICC_BWMON
237 tristate "QCOM Interconnect Bandwidth Monitor driver"
238 depends on ARCH_QCOM || COMPILE_TEST
242 Sets up driver monitoring bandwidth on various interconnects and
243 based on that voting for interconnect bandwidth, adjusting their
244 speed to current demand.
245 Current implementation brings support for BWMON v4, used for example
246 on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last
247 Level Cache (memnoc). Usage of this BWMON allows to remove some of
248 the fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high
249 memory throughput even with lower CPU frequencies.
