From b88641e236fbd0187858b8a974c44c2b4c450352 Mon Sep 17 00:00:00 2001 From: John Snow Date: Mon, 11 Jan 2016 14:10:43 -0500 Subject: libqos/ahci: Switch to mutable properties ATAPI commands are, unfortunately, weird in that they can be either DMA or PIO depending on a header bit. In order to accommodate them, I'll need to make AHCI command properties mutable so we can toggle between which "flavor" of ATAPI command we want to test. The default ATAPI transfer mechanism is PIO and the default properties are adjusted accordingly.
