[PATCH] ACPI: Add ASPT test

Colin King colin.king at canonical.com
Tue Dec 8 14:32:51 UTC 2015


From: Colin Ian King <colin.king at canonical.com>

This table is not well described anywhere, however it is a frequently
used table on AMD machines and the format is relatively simple set of
4 32 bit addresses.  This table has been discussed on the ACPICA
devel mailing list:

https://lists.acpica.org/pipermail/devel/2015-November/000850.html

and this description matches the various acpi dumps of this table
on AMD machines that I have access too. I believe the table refers
to an AMD performance monitoring feature.
