Consider the case when the whole buffer is zero and end is unaligned.
If i <= tail, we return 1 and do one unaligned WRITE, RMW happens.
If i > tail, we do on aligned WRITE_ZERO (or skip if target is zeroed)
and again one unaligned WRITE, RMW happens.

First, this permission never protected a node from being changed, as
generic child-replacing functions don't check it.
Second, it's a strange thing: it presents a permission of parent node
to change its child. But generally, children are replaced by different
m
This demonstrates what happens when the block status changes in
sub-min_sparse granularity, but all of the parts are zeroed out. The
alignment logic in is_allocated_sectors() prevents that the target image
remains fully sparse as expected, but turns it into a data cluster of
explicit zeros.

The calculation in sector2cluster() is done relative to the offset of
the root directory. Any writes to blocks before the start of the root
directory (in particular, writes to the FAT) result in negative values,
which are not handled correctly in vvfat_write().
This changes sector2cluster() to ret

Here's yet another stab at enabling QEMU on systems with
pathologically reduced IPA ranges such as the Apple M1 (previous
version at [1]). Eventually, we're able to run a KVM guest with more
than just 3GB of RAM on a system with a 36bit IPA space, and at most
123 vCPUs.
This also addresses some pa
Previous patch [1] added explicit whitespace padding to OEM_ID/OEM_TABLE_ID
values used in test_oem_fields() testcase to avoid false positive and
bisection issues when QEMU is switched to \0' padding. As result
testcase ceased to test values that were shorter than max possible
length values.
Updat
The highmem attribute is nothing but another way to express the
PA range of a VM. To support HW that has a smaller PA range then
what QEMU assumes, pass this PA range to the virt_set_memmap()
function, allowing it to correctly exclude highmem devices
if they are outside of the PA range.
Signed-off
Even when the VM is configured with highmem=off, the highest_gpa
field includes devices that are above the 4GiB limit.
Similarily, nothing seem to check that the memory is within
the limit set by the highmem=off option.
This leads to failures in virt_kvm_type() on systems that have
a crippled IPA
Just like we can control the enablement of the highmem PCIe region
using highmem_ecam, let's add a control for the highmem GICv3
redistributor region.
Similarily to highmem_ecam, these redistributors are disabled when
highmem is off.

Now that the devices present in the extended memory map are checked
against the available PA space and disabled when they don't fit,
there is no need to keep the same checks against highmem, as
highmem really is a shortcut for the PA space being 32bit.
