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).

Description: Writes are equivalent to writing to
/sys/devices/system/cpu/cpuN/dscr on all CPUs.
Reads return the last written value or 0.
This value is not a global default: it is a way to set
all per-CPU defaults at the same time.
Values: 64 bit unsigned integer (bit field)
What: /sys/devices/system/cpu/cpu[0-9]+/dscr
Date: 13-May-2014
KernelVersion: v3.15.0
Contact:
Description: Default value for the Data Stream Control Register (DSCR) on
a CPU.
This default value is used when the kernel is executing and
for any process that has not set the DSCR itself.
If a process ever sets the DSCR (via direct access to the
SPR) that value will be persisted for that process and used
on any CPU where it executes (overriding the value described
here).
If set by a process it will be inherited by child processes.
Values: 64 bit unsigned integer (bit field)
