The patches the Intel guys are submitting at the minute are mainly for the off-SoC devices at least as far as I noticed. This'll impact anyone who ends up using ACPI, we need to at least pay attention to what's going on there. > with plain ACPI-5.0.

It's going to be way more than that for the whole system, and you can't assume that all the system integrators are going to pay a blind bit of notice to the reference designs. Some will just clone them but others will bin them and do their own thing. --STPqjqpCrtky8aYs Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBAgAGBQJSp2nlAAoJELSic+t+oim9kiUP/0P+O+z8QpfJzsFiOBAQtvtj +/z7FJPJf1VMeDaNeu3Z+eqd3gnsBSDAVROBJq5tBJV+x4TiRqBjb0EtB+Rnlss9 KudNuP/+x/Fh6p6RJWGl4zWMN6L7b410UNzSLNyNYdUw0NYEykLFOKnTz9CEYMLW YEpxWql4Liv66G/rauilsMnF4iwoYhx7w/BfV2xr/OB59XPsbAyVBJFlwAjw6M56 NTFg7z8iAq0xRRhZiKmCCv5SnCluqqpRvjNuZyj7z5VObgH03akJ4Pzd4r/9viQM 7AP/Qg12vUJaauOS17+1TRkS5w5j/eWX5or+RdBuPPiIhp5qJ3/gCcLXGzUAZnsC NJnhKW2HGBQfboliWeRyMLgJ9Dm+pgRQdHCDpOD+K6GdUm3Q64n8CgviA91aB4Jq 1moEkFp+TwJ+ArQJ4j01ZgavqFwYizc+/wJ7aRggh1IfM5TCSlXE04C6ZICpMn3v RbKYN6b+xRLX0XX2Mt8MnXXo2y57m6LcejPRlJj6mn2RXNEIZlLM9LVfwF/U6Np6 z3pZFnEzfnC/FAziyANq3YRBqV9mW4H1cQSsTmczmt4rx0mzMkOnoBuC2ua8J4Wi y5AjlaLyZqU6l2TtWEND20y3pNmEyYZT7jNwxvWT7vpfOq4etFKm5T/FwBhFGwax 9Q3k/PjLAue/fMHpx/z1 =cosg -----END PGP SIGNATURE----- --STPqjqpCrtky8aYs--
