└─>ARM SMMU QCOM implementation defined debug support
In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Support for implementation specific debug features in ARM SMMU
hardware found in QTI platforms. This include support for
the Translation Buffer Units (TBU) that can be used to obtain
additional information when debugging memory management issues
like context faults.
Say Y here to enable debug for issues such as context faults
or TLB sync timeouts which requires implementation defined
register dumps.
