CONFIG_CORESIGHT_CATU: Coresight Address Translation Unit (CATU) driver

General informations

The Linux kernel configuration item CONFIG_CORESIGHT_CATU has multiple definitions:

Coresight Address Translation Unit (CATU) driver found in drivers/hwtracing/coresight/Kconfig

The configuration item CONFIG_CORESIGHT_CATU:

• prompt: Coresight Address Translation Unit (CATU) driver
• type: tristate
• depends on: CONFIG_CORESIGHT_LINK_AND_SINK_TMC
• defined in drivers/hwtracing/coresight/Kconfig
• found in Linux kernels: 5.10–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: coresight-catu

Help text

Enable support for the Coresight Address Translation Unit (CATU). CATU supports a scatter gather table of 4K pages, with forward/backward lookup. CATU helps TMC ETR to use a large physically non-contiguous trace buffer by translating the addresses used by ETR to the physical address by looking up the provided table. CATU can also be used in pass-through mode where the address is not translated.

To compile this driver as a module, choose M here: the module will be called coresight-catu.
