threeeye bc1d038eac REVVL 6 Pro kernel bring-up: full working tree snapshot (2026-09-12)
Squashed backup commit (no shallow-clone history issues) of
xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream
commit 9eece662e) plus all fixes applied to get everpal_defconfig building
clean against a modern (GCC 15.2.0) toolchain -- see the previous commit
message on the lineage-23.2 branch (also in this repo history is not
available here since this is a squashed snapshot; full incremental history
lives in the local DL380 checkout and the upstream GitHub remote).

Select this option to enable driver support for IBM Coherent
Accelerators (CXL). CXL is otherwise known as Coherent Accelerator
Processor Interface (CAPI). CAPI allows accelerators in FPGAs to be
coherently attached to a CPU via an MMU. This driver enables
userspace programs to access these accelerators via /dev/cxl/afuM.N
devices.
CAPI adapters are found in POWER8 based systems.
If unsure, say N.

Select this option to enable support for bi-modal CAPI cards, such as
the Mellanox CX-4.
