2014-01-03mmio: Obviously wrong notification register namehornet
The "4.2.3.3 Notifying The Device" section said "writing the index of the updated queue to the QueueNum". This is obviously wrong - should read "QueueNotify".

2013-12-02latexify document more.rusty
This change: - Turns formatted lists into real lists (itemize, etc). - Turns ascii tables into real tables. - Use \ldots for ... - Moves \footnote to immediately after what it refers to, otherwise we get awkward whitespace before the superscript. - List of stats for balloon contains values in () to match other lists. - Puts lstlisting around CCW code example - Cross references to numbered steps, rather than hardcoded (2) etc. No actual contents changed.

2013-12-02Specify requirements more clearly.rusty
The spec language is mostly written with a view to driver authors, and contains assumptions, eg: The Device Status field is updated by the OS and driver... But the spec is for both device and driver authors. It should specify exactly what is to be done, and by whom, eg: The driver MUST update the Device Status field... 1) Change from passive to active (eg "foo must be reset" => "driver must reset foo"). 2) Upcase SHOULD, MUST etc. There are probably more that I missed. 3) Make the following requirements explicit: - The driver must not clear device status bits. - Make bad on looped descriptors explicit. - Driver must not set VRING_DESC_F_INDIRECT unless negotiated feature. - Available/used ring sections rewritten to be more explicit that driver must not set VRING_AVAIL_F_NO_INTERRUPT. - Following device initialization sequence is a MUST. - Driver must not continue initialization if it sets FAILED. - "memory barriers" are now a MUST, though the weasel-word "suitable" was added. - Driver MUST notify device. 4) Misc changes: - Use "device offers" / "driver accepts" language for feature negotiation. - config space always uses little-endian, remove 'generally'. - "descriptor chain" term used everywhere. - Extraneous "+" deleted. - Remove "Unless explicitly specified otherwise" from PCI spec endian sentence. - Refer to notify_off_multiplier in queue_notify_off discussion.

2013-12-02Terminology: Device and driver, not host and guest.rusty
We've mixed both together, whereas from a spec-reader point of view, "driver" and "device" is probably clearer. CCW part incorporated: Switch the parts of the virtio-ccw specification that did not already to device/driver instead of guest/host. For more general discussions, host/guest is kept (like when talking about guest<->host notifications in general). This should make things more consistent.
