Hi Pawel, Nice commit! I only have three minor changes to suggest. 1) I usually like to be completely explicit on who should ignore values (ie. driver or device). 2) Trying to be explicit on what to do with different Device Version Number field. 3) Generally prefer form "Driver must ignore X" to "X must be ignored by driver". Cheers, Rusty. diff --git a/content.tex b/content.tex index 9d46852..4f3c0dc 100644 --- a/content.tex +++ b/content.tex @@ -1417,17 +1417,16 @@ All register values are organized as Little Endian. endfoot endlastfoot mmioreg{MagicValue}{Magic value}{0x000}{R}{% - MUST be 0x74726976 (a Little Endian equivalent of the "virt" string). + Devices MUST return 0x74726976 (a Little Endian equivalent of the "virt" string).
