Hi,
Due to very limited space in the setup_header this patch series introduces new
kernel_info struct which will be used to convey information from the kernel to
the bootloader. This way the boot protocol can be extended regardless of the
setup_header limitations. Additionally, the patch series in
This field contains maximal allowed type for setup_data.

The setup_data is a bit awkward to use for extremely large data objects,
both because the setup_data header has to be adjacent to the data object
and because it has a 32-bit length field. However, it is important that
intermediate stages of the boot process have a way to identify which

The relationships between the headers are analogous to the various data

When using posted interrupts and the guest migrates MSI from vCPUs Xen
needs to flush any pending PIRR vectors on the previous vCPU, or else
those vectors could get wrongly injected at a later point when the MSI
fields are already updated.

The current implementation of host_maskall makes it sticky across
assign and deassign calls, which means that once a guest forces Xen to
set host_maskall the maskall bit is not going to be cleared until a
call to PHYSDEVOP_prepare_msix is performed. Such call however
shouldn't be part of the normal

Thanks Michael,
In the meantime, we're looking at just disabling BLS by default in the
grub packages within Fedora when its run on a Xen guest. This means we
should at least be at a point where Fedora guests will work reliably
again as Xen guests.
It seems to be agreed that this will stay in
