Subject: [PATCH 0/2] bus: efi: add basic ACPI bus infrastructure
Date: Wed, 4 Dec 2019 15:07:19 +0100 [thread overview]
Message-ID: <20191204140721.20299-1-ahmad@a3f.at> (raw)
Microsoft specifies an ACPI Watchdog Action Table for its server
offerings that abstracts away hardware-specifics of watchdog devices.
This can be an alternative to implementing many different watchdog
driver in barebox for x86 H/W, as the driver is implemented in the
BIOS and barebox would only need to implement the H/W.
Unfortunately, I don't H/W handy that provides the WDAT table.
I've implemented the ACPI bus nevertheless, so here's the patch.
I haven't found anything else I'd like to do with ACPI, so I wrote a
sample driver to test the API. Not sure if it should go into the tree,
but I'd be in favor of adding it till there is a real user of the ACPI
bus (besides devinfo).
Cheers
Ahmad
