Kevin Wolf a1678e85db Multiboot support: Fix rom_copy
ROMs need to be loaded if they are anywhere in the requested area, not
only at the very beginning. This fixes Multiboot with ELF kernels that
have more than one program header.

Gerd Hoffmann 345c22aa80 roms: remove option rom packing logic
Now that we load the option roms via fw_cfg, we can stop copying
them to the 0xc000 -> 0xe000.  The patch does just that.

Also the rom loader gets simplified as all remaining users of the
rom loader load the bits at a fixed address so the packing and
aligning logic can go away.

Gerd Hoffmann e6ea832410 fw_cfg: add API for file transfer.
This patch adds a file transfer interface to fw_cfg.  Intended to be
used for passing non-pci option roms and vgabios to seabios.  Namespace
is modeled after the existing cbfs filesystem support in seabios.

Reading the new FW_CFG_FILE_DIR entry returns a file list.
Fields there are in network byte order (aka bigendian).

Gerd Hoffmann 898829d5c7 pci romfiles: add property, add default to PCIDeviceInfo
This patch adds a romfile property to the pci bus.  It allows to specify
a romfile to load into the rom bar of the pci device.  The default value
comes from a new field in PCIDeviceInfo.  The property allows to change
the file and also to disable the rom loading using an empty string.

Anthony Liguori 72bb3c7571 Support PCI based option rom loading
Currently, we preload option roms into the option rom space in memory.  This
prevents DDIM from functioning correctly which severely limits the number
of roms we can support.

This patch introduces a pci_add_option_rom() which registers the
PCI_ROM_ADDRESS bar which points to our option rom.  It also converts over
the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this
new mechanism.

The result is that PXE boot functions even with three unique types of cards.

Anthony Liguori 4b5db3749c Fix VMware VGA depth computation
VMware VGA requires that the depth presented to the guest is the same as the
DisplaySurface that it renders to.  This is because it performs a very simple
memcpy() to blit from one surface to another.

We currently hardcode a 24-bit depth.  The surface allocator for SDL may, and
usually will, allocate a surface with a different depth causing screen
corruption.

This changes the code to allocate the DisplaySurface before initializing the
device which allows the depth of the DisplaySurface to be used instead of
hardcoding something.

Anthony Liguori 3c547d7bb7 Make sure to enable dirty tracking of VBE vram mapping
Apparently, VBE maps the VGA vram to a fixed physical location.  KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them.  Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.

This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.

Cirrus does not enable VBE so it would not be a problem when using Cirrus.

happen, we just not tell it the config space changed for now until we
implement the correct callback for that.

On hosts without high-res timers it is impossible to inject rtc interrupt
faster then 1kHz. Windows sometimes configures RTC to generate 1kHz
interrupts, so we can't inject missed interrupts when running on such
hosts. Always injecting an interrupt on REG_C read is also not an option
since Windows wait for REG_C to become zero with interrupt disabled
during boot. This patch uses mixed approach: accelerate timer + inject
up to 1000 interrupts on REG_C read.

Alexander Graf 8cb310e130 Add S390x virtio machine description
In order to use the new S390x virtio bus we just introduced, we also
