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).

1) perf build
|
|
=============
|
|
The perf build process consists of several separated building blocks,
|
|
which are linked together to form the perf binary:
|
|
- libperf library (static)
|
|
- perf builtin commands
|
|
- traceevent library (static)
|
|
- GTK ui library
|
|
|
|
Several makefiles govern the perf build:
|
|
|
|
- Makefile
|
|
top level Makefile working as a wrapper that calls the main
|
|
Makefile.perf with a -j option to do parallel builds.
|
|
|
|
- Makefile.perf
|
|
main makefile that triggers build of all perf objects including
|
|
installation and documentation processing.
|
|
|
|
- tools/build/Makefile.build
|
|
main makefile of the build framework
|
|
|
|
- tools/build/Build.include
|
|
build framework generic definitions
|
|
|
|
- Build makefiles
|
|
makefiles that defines build objects
|
|
|
|
Please refer to tools/build/Documentation/Build.txt for more
|
|
information about build framework.

|
2) perf build
|
|
=============
|
|
The Makefile.perf triggers the build framework for build objects:
|
|
perf, libperf, gtk
|
|
|
|
resulting in following objects:
|
|
$ ls *-in.o
|
|
gtk-in.o libperf-in.o perf-in.o
|
|
|
|
Those objects are then used in final linking:
|
|
libperf-gtk.so <- gtk-in.o libperf-in.o
|
|
perf <- perf-in.o libperf-in.o
|
|
|
|
|
|
NOTE this description is omitting other libraries involved, only
|
|
focusing on build framework outcomes
