virtio: Force use of power-of-two for descriptor ring sizes

2007-11-12T02:59:40+00:00

The virtio descriptor rings of size N-1 were nicely set up to be
aligned to an N-byte boundary.  But as Anthony Liguori points out, the
free-running indices used by virtio require that the sizes be a power
of 2, otherwise we get problems on wrap (demonstrated with lguest).

So we replace the clever "2^n-1" scheme with a simple "align to page
boundary" scheme: this means that all virtio rings take at least two
pages, but it's safer than guessing cache alignment.

lguest: Fix lguest virtio-blk backend size computation

2007-11-12T02:59:26+00:00

This seems like an obvious typo but it's worked in the past because the virtio
blk frontend just ignores the length field on completion.

Went through the documentation doing typo and content fixes.  This
patch contains only comment and whitespace changes.

lguest: example launcher header cleanup.

2007-10-25T04:09:25+00:00

Now the kernel headers are clean for userspace export, we don't need
to typedef kernel types before including them.  We also don't need
pci_ids.h (that was from an earlier virtio draft).

Use "struct boot_params" in example launcher

2007-10-23T05:49:57+00:00

Now that the "struct boot_params" is userspace accessible, we don't need
magic numbers.

Loading bzImage directly.

2007-10-23T05:49:57+00:00

Now arch/i386/boot/compressed/head.S understands the hardware_platform field,
we can directly execute bzImages.  No more horrific unpacking code.

Revert lguest magic and use hook in head.S

2007-10-23T05:49:57+00:00

Version 2.07 of the boot protocol uses 0x23C for the hardware_subarch
field, that for lguest is "1".  This allows us to use the standard
boot entry point rather than the "GenuineLguest" string hack.

The standard entry point also clears the BSS and copies the boot parameters
and commandline for us, saving more code.

Update lguest documentation to reflect the new virtual block device name.
