Package: src:linux
Version: 5.18.8-1
Hello,
An Armv9 architectural feature, Trace Buffer Extension (FEAT_TRBE), is
making its way into upcoming CPU cores. TRBE can be found described in
[1] and [2].
Support for this is already in the kernel (with some erratum fixes
landing in 5.18), I was going to ask if it can please be enabled with
the following Kconfig options?
CONFIG_CORESIGHT=m
CONFIG_CORESIGHT_SOURCE_ETM4X=m
CONFIG_CORESIGHT_TRBE=m
This would be to allow Neoverse-N2 parts (and others) to leverage this
feature when running on Debian Bookworm.
Cheers!
