Hi Andrew,

As specified in samples/trace_events/Makefile:

      If you include a trace header outside of include/trace/events
      then the file that does the #define CREATE_TRACE_POINTS must
      have that tracer file in its main search path. This is because
      define_trace.h will include it, and must be able to find it from
      the include/trace directory.

Without this the following compilation error is seen:

        CC      drivers/soc/qcom/pmic_pdcharger_ulog.o
      In file included from drivers/soc/qcom/pmic_pdcharger_ulog.h:36,
                       from drivers/soc/qcom/pmic_pdcharger_ulog.c:15:
      ./include/trace/define_trace.h:95:42: fatal error: ./pmic_pdcharger_ulog.h: No such file or directory
         95 | #include TRACE_INCLUDE(TRACE_INCLUDE_FILE)
            |                                          ^
      compilation terminated.

I never experienced such error, and no CI even reported it, can you explain how you got this ?

To be honest, I am unsure why I'm experiencing this (and until I saw
another thread about it today I thought maybe I had screwed something
up!).

I just took it as an opportunity to try and read up on the tracing
infrastructure and sent this series. Definitely no expertise with the
in's and out's of tracing :)

I'm able to reproduce this on next-20231211:

     ahalaney@fedora ~/git/linux-next (git)-[b4/b4-stmmac-handle-mdio-enodev] % ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make mrproper
     <snip>
     ahalaney@fedora ~/git/linux-next (git)-[b4/b4-stmmac-handle-mdio-enodev] % ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig
     <snip>
     *** Default configuration is based on 'defconfig'
     #
     # configuration written to .config
     #

Realized I missed a step, actually enabling tracing and the driver at
play here... but the result is the same.

Attached is a config where I hit this.

     130 ahalaney@fedora ~/git/linux-next (git)-[b4/b4-stmmac-handle-mdio-enodev] % ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make drivers/soc/qcom/pmic_pdcharger_ulog.o
       HOSTCC  scripts/dtc/dtc.o
     <snip>
       CC      drivers/soc/qcom/pmic_pdcharger_ulog.o
     In file included from drivers/soc/qcom/pmic_pdcharger_ulog.h:36,
		     from drivers/soc/qcom/pmic_pdcharger_ulog.c:15:
     ./include/trace/define_trace.h:95:42: fatal error: ./pmic_pdcharger_ulog.h: No such file or directory
        95 | #include TRACE_INCLUDE(TRACE_INCLUDE_FILE)
     <snip>
     2 ahalaney@fedora ~/git/linux-next (git)-[b4/b4-stmmac-handle-mdio-enodev] %

I even tried it in a fedora container with the above build commands and
the following podman invocation (plus some package installs) and saw the error:

     podman run -it -v ~/git/linux-next:/linux-next:z quay.io/fedora/fedora:latest /bin/bash

So I'm unsure if it's a fedora package version thing (which I'm running on my host)
or something else... Once I saw it was sort of spelled out in the
examples I referenced here I just decided it was something needed
fixing, regardless of why I'm hitting it while others seem ok.

Interesting, I don't get the problem with the same tag, same .config but with gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu

I'll try with gcc 13.

Thanks,
Neil
