Subject: No cpufreq entries with omap2plus_defconfig since "cpufreq: dt-platdev: Support building as module" (commit 3b062a08)
Date: Thu, 2 May 2024 13:04:56 +0200 [thread overview]
Message-ID: <657f402f-3c22-48bb-8102-ab35a74444c1@wizzup.org> (raw)
Hi,
I was looking at switching my Motorola Droid 4 phone from Linux 6.1 to
Linux 6.6, and it no longer gets any cpufreq entries on boot, and I
found cpufreq_dt was no longer loaded. I tried to force the issue by
modprobe it, but to no avail. The same issue occurs on the latest 6.9.
After a bit of digging it looks like the problem is that
cpufreq-dt-platdev can be built as a module and when this the case
(apparently the default), cpufreq_dt doesn't work. With the
omap2plus_defconfig, CONFIG_CPUFREQ_DT_PLATDEV is indeed set to module.
When I manually probe cpufreq-dt-platdev and cpufreq_dt, I get the
cpufreq_entries back.
Searching around I found this debian bug report [1] which just flips the
CONFIG_CPUFREQ_DT_PLATDEV back to '=y', but I think there might be a
deeper issue here.
Is there a way to define this relationship/dependency for cpufreq-dt, so
that it will automatically load this module?
Regards,
Merlijn
