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

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.
