pci resource address
Hello,
we have a own xxx.c32 file. With syslinux 4.07
With this file we read some information from a pci device.

return (void *)(pci_readl(addr + 0x10) & ~0xf);

void *fpga_addr;
struct pci_domain *domain;
struct pci_device *dev;
domain = pci_scan();...

[PATCH v3 0/5] hvmloader: Make ROM dependencies optional
This patch set mainly allows the user to build a seabios or rombios only
version of hvmloader.
In addition, when building a seabios only hvmloader, Option ROMs like
vgabios and etherboot are no longer required, and therefore can be disabled
from the build. Dependency on the bcc compiler can also be avoided the
same way.

GFX Passthrough
Hi List,
many People seem to be interested in the Graphic-Card Passthrough Feature (for
more or less obvious reasons).
Official Support is still under development, and i hope not to interfere with it
in any (bad) way ...
But i remember my own painfull and timeconsuming research when i wanted this
feature to work, so i thought perhaps this spares some time for the unpatient
users like me :)
