nvidia-tegra-modules.git/drivers/cpufreq/Makefile, branch gpu-paging NVIDIA's kernel modules to support tegra chips (used in Jetson boards) cpufreq: introduce CPU EMC mapping table helper 2019-09-10T09:23:43+00:00 Leon Yu leoyu@nvidia.com 2019-08-23T04:59:24+00:00 589684582480c2b56306d889e5cf8b970fce9d9d We've been using duplicate code and incompatible format/name/type for CPU to EMC frequency mapping table related stuffs on different SoCs. This not only confuses users but also makes it difficult to customize and maintain these mapping tables. This change aims to provide unified interfaces and structures that can be used by existing (and also future) cpufreq drivers.

We've been using duplicate code and incompatible format/name/type for
CPU to EMC frequency mapping table related stuffs on different SoCs.
This not only confuses users but also makes it difficult to customize
and maintain these mapping tables.

This change aims to provide unified interfaces and structures that can
be used by existing (and also future) cpufreq drivers.

It has following changes from t186. - The cpufreq driver needs to get NDIV table from BPMP. This will be a single table for all clusters. T186 used two frequency tables for each cluster since they were different v/f curves. Additionally, it is no longer need vhints as this will be provided by MTS. - Support 4 clusters with 2 cores each. The read frequency of cpu is changed. It is read from each cpu NVIDIA defined system register NVFREQ_FEEDBACK. The request frequency of cpu is based on NDIV value. - Update cpu to emc frequency request mapping by provide a default mapping, which uses cpu range to emc frequency conversion. It can be overrided via device tree.
