Subject: Missing default handler for the EmbeddedControl OpRegion
Date: Mon, 29 Apr 2024 17:54:58 +0300 [thread overview]
Message-ID: <Zi+0whTvDbAdveHq@kuha.fi.intel.com> (raw)
Hi,
There's a bug that is caused by an EmbeddedControl OpRegion which is
declared inside the scope of a specific USB Type-C device (PNP0CA0):
https://bugzilla.kernel.org/show_bug.cgi?id=218789
It looks like that's not the only case where that OpRegion ID is used
outside of the EC device scope. There is at least one driver in Linux
Kernel (drivers/platform/x86/wmi.c) that already has a custom handler
for the EmbeddedControl OpRegion, and based on a quick search, the
problem "Region EmbeddedControl (ID=3) has no handler" has happened
with some other devices too.
Br,
