UEFI Forum recommends FWTS for it’s ACPI tests

FWTS has had ACPI tests for a while, and it’s basically the best public set of ACPI tests available. Better than anything the UEFI Forum has, like the SCTs. They’ve been using FWTS in the UEFI plugfests for a while, for ACPI purposes. Now the UEFI Forum is more formally recommending FWTS. Alex Hung of Canonical announces a new milestone for FWTS, the FirmWare Test Suite:

FWTS 17.03.00 is recommended as the ACPI 6.1 SCT

We have achieved another important milestone! The UEFI Board of Directors recommends Firmware Test Suite (FWTS) release 17.03.00 as the ACPI v6.1 Self-Certification Test (SCT), More information is available at:
http://www.uefi.org/testtools
Thank you all for who contributed patches, reported bugs, provided feedbacks and used FWTS in your work.

Thanks, FWTS, for having the best ACPI tests available!
