Although this driver is a good use case for having a directory
that is not other directories and then subdirectories with more

increases complexity so to avoid that just split out the

Now that we have the redirectable Xen backend operations we can build the
PV backends even without the Xen libraries.

XC_PAGE_SIZE comes from the actual Xen libraries, while XEN_PAGE_SIZE is
provided by QEMU itself in xen_backend_ops.h. For backends which may be
built for emulation mode, use the latter.

We provided the backend-facing evtchn functions very early on as part of

Whem emulating Xen, multi-page grants are distinctly non-trivial and we

The xen-block code ends up calling aio_poll() through blkconf_geometry(),
which means we see watch events during the indirect call to
xendev_class->realize() in xen_device_realize(). Unfortunately this call
is made before populating the initial frontend and backend device nodes

Switching TTBR while the MMU is on is not safe. Now that the identity
mapping will not clash with the rest of the memory layout, we can avoid
creating temporary page-tables every time a CPU is brought up.
The arm32 code will use a different approach. So this issue is for now

From: Julien Grall
Xen is currently not fully compliant with the Arm Arm because it will
switch the TTBR with the MMU on.
In order to be compliant, we need to disable the MMU before
switching the TTBR. The implication is the page-tables should
contain an identity mapping of the code switching th

At the moment, switch_ttbr() is switching the TTBR whilst the MMU is
still on.
Switching TTBR is like replacing existing mappings with new ones. So
we need to follow the break-before-make sequence.
In this case, it means the MMU needs to be switched off while the
TTBR is upda
From: Julien Grall
In follow-up patches we will need to have part of Xen identity mapped in
order to safely switch the TTBR.
On some platform, the identity mapping may have to start at 0. If we always
keep the identity region mapped, NULL pointer dereference would lead to
access to valid mapping

Hi all,
Currently, Xen on Arm will switch TTBR whilst the MMU is on. This is
similar to replacing existing mappings with new ones. So we need to
follow a break-before-make sequence.
When switching the TTBR, we need to temporarily disable the MMU
before updating the TTBR. This
From: Julien Grall
At the moment, the temporary mapping is only used when the virtual
runtime region of Xen is clashing with the physical region.
In follow-up patches, we will rework how secondary CPU bring-up works
and it will be convenient to use the fixmap area for accessing
the root page-tab
