From ff9ba54ce190da0b5df5306b1fe99c796265e30e Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Tue, 9 Feb 2021 17:38:23 +0200 Subject: sb,soc/amd: Drop OSFL method in ASL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Variable OSVR had a static value of 3 and OSFL() did not actually call _OSI or _OS methods. The conditional in HDA _INI method of OSVR is dropped and use of DMA NoSnoop attribute remains disabled to retain previous behaviour. For soc/amd/picasso a different decision was made in CB:40782 as HDA _INI method was just dropped and default configuration enables use of DMA NoSnoop attribute.
