Wysocki" , Len Brown , Robert Moore Cc: linux-acpi@vger.kernel.org, acpica-devel@lists.linux.dev Subject: Missing default handler for the EmbeddedControl OpRegion Message-ID: Precedence: bulk X-Mailing-List: linux-acpi@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline 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.
