Subject: [RFC] Allow empty Trigger Error Action Table
Date: Mon, 9 Jan 2012 16:49:43 +0100 [thread overview]
Message-ID: <1326124184-10084-1-git-send-email-niklas.soderlund@ericsson.com> (raw)
When troubleshooting some BIOS code I encounter strange errors about firmware bugs. On closer inspection I found that the Trigger table returned from the firmware was empty but the header looked OK:
header_size = 16
table_size = 16
entry_count = 0
When looking at einj.c I found that this header would result in the error I was receiving. I took a quick look at the docs and from what I can tell this is a valid header, yes?
I don't know much about ACPI so I might be way off but the attached patch fix the error message for me (however I still can't detect the injected error but that might depend on my detection code or buggy firmware...)
Thanks
// Niklas
