Hi,
I am trying to improve cross compiling support for kselftest recently. Right
now I am stuck when I want to enable KBUILD_OUTPUT(O=xxx). It exist in wiki of
kselftest[1]. Hope it is not a duplicated work.
It seems that only perf tools(tools/perf) support it. And I could know that the
following Makefile are called when building perf:
tools/Makefile
tools/perf/Makefile
tools/perf/Makefile.perf
tools/build/Makefile.build
But I could not get the idea that how to do it for kselftest. Is there any
existed infrastructure I could use?
I am appreciated if there is any suggestions or ideas. Thanks in advance.
Regards
Bamvor

Just want to echo the need for this feature because trying to build kselftests for a kernel built with KBUILD_OUTPUT is broken due to hard-coded assumptions about paths to headers, etc. I haven't dug any deeper into how to fix it though...
