From fdc047cb06529edebed75a185b2bab7383161470 Mon Sep 17 00:00:00 2001 From: mstsirkin Date: Wed, 22 Apr 2015 08:26:11 +0000 Subject: pci: missing documentation for dealing with 64 bit config fields pci spec says what width access to use for 32, 16 and 8 bit fields, but does not explicitly say what to do for 32 bit fields. As we have text that says driver must treat 64 bit accesses as non-atomic, this seems to imply driver should always do two 32 bit wide accesses. Let's make this an explicit requirement, and require devices to support this. VIRTIO-139 Signed-off-by: Michael S.
