select QCOM_SCM
help
The On Chip Memory (OCMEM) allocator allows various clients to
allocate memory from OCMEM based on performance, latency and power
requirements. This is typically used by the GPU, camera/video, and
audio components on some Snapdragon SoCs.
config QCOM_PDR_HELPERS

depends on ARCH_QCOM || COMPILE_TEST
depends on (QCOM_COMMAND_DB || !QCOM_COMMAND_DB)
help
Support for communication with the hardened-RPM blocks in
Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
internal bus to transmit state requests for shared resources. A set
of hardware components aggregate requests for these resources and
help apply the aggregated state on the resource.
config QCOM_RPMHPD
tristate "Qualcomm RPMh Power domain driver"
depends on QCOM_RPMH && QCOM_COMMAND_DB
help
QCOM RPMh Power domain driver to support power-domains with
performance states. The driver communicates a performance state
value to RPMh which then translates it into corresponding voltage
for the voltage rail.
config QCOM_RPMPD
tristate "Qualcomm RPM Power domain driver"
depends on PM && OF
depends on QCOM_SMD_RPM
select PM_GENERIC_DOMAINS
select PM_GENERIC_DOMAINS_OF
help
QCOM RPM Power domain driver to support power-domains with
performance states. The driver communicates a performance state
value to RPM which then translates it into corresponding voltage
for the voltage rail.
config QCOM_SMEM
tristate "Qualcomm Shared Memory Manager (SMEM)"
depends on ARCH_QCOM || COMPILE_TEST
depends on HWSPINLOCK
help
Say y here to enable support for the Qualcomm Shared Memory Manager.

Current implementation brings support for BWMON v4, used for example
on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last
Level Cache (memnoc). Usage of this BWMON allows to remove some of
the fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high
memory throughput even with lower CPU frequencies.
