CONFIG_S3C2410_DMA_DEBUG: S3C2410 DMA support debug

General informations

The Linux kernel configuration item CONFIG_S3C2410_DMA_DEBUG has multiple definitions:

S3C2410 DMA support debug found in arch/arm/mach-s3c2410/Kconfig

The configuration item CONFIG_S3C2410_DMA_DEBUG:

• prompt: S3C2410 DMA support debug
• type: bool
• depends on: CONFIG_ARCH_S3C2410 && CONFIG_S3C2410_DMA
• defined in arch/arm/mach-s3c2410/Kconfig
• found in Linux kernels: 2.6.9–2.6.20

Help text

Enable debugging output for the DMA code. This option sends info to the kernel log, at priority KERN_DEBUG.

Note, it is easy to create and fill the log buffer in a small amount of time, as well as using an significant percantage of the CPU time doing so.
