2014-02-10PCI Section Reworkrusty
1) Minor changes from must to MUST etc. 2) More references using \ref. 3) Move section on capabilities first, before we talk about the common config layout. The previous order made sense for legacy. 4) Make explicit subsections for each type of capability and move more information into them. 5) Make it clear that there must be one or more. 6) Include 'struct virtio_pci_cap cap;' in struct virtio_pci_cfg_cap to match virtio_pci_notify_cap. 7) Explicitly note there's no way to negotiate the queue size for a legacy device. 8) Fix old language on config change event: config is not in the pci configuration space. 9) Explicitly state what the driver should do to use virtio_pci_cfg_cap.

2014-02-07block: legacy SCSI command fix.rusty

The order of the fields in the legacy PCI header seems to get messed up in the new spec, with the "Queue Address" moved behind "Queue Notify".

2014-01-12.exrc: rename to _vimrcmstsirkin
.exrc is not allowed in the OASIS Library, since "dot" files are special files in file system. They are specifically disallowed by the Naming Directives [1] : "Filenames and directory names must neither begin nor end with a punctuation character (period or hyphen). [...]" Rename to _vimrc which also works - from vim help: d. If the 'exrc' option is on (which is not the default), the current directory is searched for three files. The first that exists is used, the others are ignored. - The file ".vimrc" (for Unix, Amiga and OS/2) (*) "_vimrc" (for MS-DOS and Win32) (*) - The file "_vimrc" (for Unix, Amiga and OS/2) (*) ".vimrc" (for MS-DOS and Win32) (*) - The file ".exrc" (for Unix, Amiga and OS/2) "_exrc" (for MS-DOS and Win32) Signed-off-by: Michael S.
