build: convert libhw to nested Makefile.objs

After this patch, the libhw* directories will have a hierarchy
that mimics the source tree. This is useful because we do have
a couple of files there that are in the top source directory.

ahci: SATA FIS is 20 bytes, not 0x20

As in the SATA and AHCI specifications, a FIS is 5 Dwords of 4 bytes
each, which comes to 20 bytes (decimal), not 0x20.

ATA: Allow WIN_SECURITY_FREEZE_LOCK as nop

When using Windows 8 with an AHCI disk drive, it issues a blue screen.
The reason is that WIN_SECURITY_FREEZE_LOCK / CFA_WEAR_LEVEL is not
supported by our ATA implementation, but Windows expects it to be there....

ide: convert ide_sector_read() to asynchronous I/O

The IDE PIO interface currently uses bdrv_read() to perform reads
synchronously. Synchronous I/O in the vcpu thread is bad because it
prevents the guest from executing code - it makes the guest
unresponsive....

ide: convert ide_sector_write() to asynchronous I/O

The IDE PIO write sector code path uses bdrv_write() and hence can make
the guest unresponsive while the I/O request is in progress. This patch
converts ide_sector_write() to use bdrv_aio_writev() by using the...

Use DMADirection type for dma_bdrv_io

Currently dma_bdrv_io() takes a 'to_dev' boolean parameter to
determine the direction of DMA it is emulating. We already have a
DMADirection enum designed specifically to encode DMA directions.
This patch uses it for dma_bdrv_io() as well. This involves removing...

ide: Add "model=s" qdev option

Allow the user to override the default disk model name "QEMU HARDDISK".

Some Linux distributions use the /dev/disk/by-id/scsi-SATA_name-of-disk-
model_serial addressing scheme when refering to partitions in /etc/fstab
and elsewhere. This causes problems when starting a disk image taken from...

ide: Adds wwn=hex qdev option

Allow the user to specify a disk's World Wide Name.

Linux guests can address disks by their unique World Wide Name number
(e.g. /dev/disk/by-id/wwn-0x5001517959123522). This patch adds support
for assigning a World Wide Name number to a virtual IDE disk....
