[redhat] New configs in kernel/dma

CKI ARK Botrequested to merge
configs/2020-12-23/kernel/dma into os-build

Hi,

As part of the ongoing rebase effort, the following configuration options need to be reviewed.

As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.

If the value for a file that is added should be changed, please reply with a better option.

CONFIG_DMA_MAP_BENCHMARK:

Provides /sys/kernel/debug/dma_map_benchmark that helps with testing performance of dma_(un)map_page.

See tools/testing/selftests/dma/dma_map_benchmark.c

Symbol: DMA_MAP_BENCHMARK [=n] Type : bool Defined at kernel/dma/Kconfig:228 Prompt: Enable benchmarking of streaming DMA mapping Depends on: DEBUG_FS [=y] Location: -> Library routines
