We fixed the bugs in it, but it's still an ugly interface, so let's see
if anybody actually depends on it. It's entirely possible that nothing
actually requires the whole "punch through read-only mappings"
semantics.
For example, gdb definitely uses the /proc/<pid>/mem interface, but it
looks like it mainly does it for regular reads of the target (that don't
need FOLL_FORCE), and looking at the gdb source code seems to fall back
on the traditional ptrace(PTRACE_POKEDATA) interface if it needs to.
If this breaks something, I do have a (more complex) version that only
enables FOLL_FORCE when somebody has PTRACE_ATTACH'ed to the target,
like the comment here used to say ("Maybe we should limit FOLL_FORCE to
actual ptrace users?").

PFs and VFs share the same structure of NDOs today,
and the VFs explicitly fails the ndo_xdp() callback stating
it doesn't support XDP.
This results in lots of:

As every dump request for the VF interface info would fail due to

Under SRIOV resource management, extra counters are allocated to VFs
from a free pool. If that pool is empty, the ALLOC_RES command for
a counter resource fails -- and this generates a misleading error
message in the message log.
Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters --
one counter per port. For ETH ports, the RoCE driver requests an
additional counter (above the guaranteed counters). If that request
fails, the VF RoCE driver simply uses the default (i.e., guaranteed)
counter for that port.
Thus, failing to allocate an additional counter does not constitute
a problem, and the error message on the PF when this occurs should
be reduced to debug level.
Finally, to identify the situation that the reason for the failure is
that no resources are available to grant to the VF, we modified the
error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded),
which more accurately describes the error.

A known weakness in ptr_ring design is that it does not handle well the
situation when ring is almost full: as entries are consumed they are
immediately used again by the producer, so consumer and producer are
writing to a shared cache line.
To fix this, add batching to consume calls: as entries are
consumed do not write NULL into the ring until we get
a multiple (in current implementation 2x) of cache lines
away from the producer. At that point, write them all out.
We do the write out in the reverse order to keep
producer from sharing cache with consumer for as long
as possible.
Writeout also triggers when ring wraps around - there's
no special reason to do this but it helps keep the code
a bit simpler.
What should we do if getting away from producer by 2 cache lines
would mean we are keeping the ring moe than half empty?
Maybe we should reduce the batching in this case,
current patch simply reduces the batching.
Notes:
- it is no longer true that a call to consume guarantees
that the following call to produce will succeed.
No users seem to assume that.
- batching can also in theory reduce the signalling rate:
users that would previously send interrups to the producer
to wake it up after consuming each entry would now only
need to do this once in a batch.
Doing this would be easy by returning a flag to the caller.
No users seem to do signalling on consume yet so this was not
implemented yet.

The only reason we called kvm_vgic_map_resources() when restoring the
ITS tables was because we wanted to have the KVM iodevs registered in
the KVM IO bus framework at the time when the ITS was restored such that
a restored and active device can inject MSIs prior to otherwise calling
kvm_vgic_map_resources() from the first run of a VCPU.
Since we now register the KVM iodevs for the redestributors and ITS as
soon as possible (when setting the base addresses), we no longer need
this call and kvm_vgic_map_resources() is again called only when first
running a VCPU.

All we need to register the ITS io device is the base address of the

set.

Instead of waiting with registering KVM iodevs until the first VCPU is
run, we can actually create the iodevs when the redist base address is
set. The only downside is that we must now also check if we need to do
this for VCPUs which are created after creating the VGIC, because there
is no enforced ordering between creating the VGIC (and setting its base
addresses) and creating the VCPUs.

As we are about to handle setting the address for the redistributor base

As we are about to fiddle with the IO device registration mechanism,
let's be a little more careful when setting base addresses as early as
possible. When setting a base address, we can check that there's
address space enough for its scope and when the last of the two
base addresses (dist and redist) get set, we can also check if the
regions overlap at that time.
This allows us to provide error messages to the user at time when trying
to set the base address, as opposed to later when trying to run the VM.
To do this, we make vgic_v3_check_base available in the core vgic-v3
code as well as in the other parts of the GICv3 code, namely the MMIO
config code.
We also return true for undefined base addresses so that the function
can be used before all base addresses are set; all callers already check
for uninitialized addresses before calling this function.

The main thing here is a new implementation of the in-kernel
XICS interrupt controller emulation for POWER9 machines, from Ben
Herrenschmidt.
POWER9 has a new interrupt controller called XIVE (eXternal Interrupt
Virtualization Engine) which is able to deliver interrupts directly
to guest virtual CPUs in hardware without hypervisor intervention.
With this new code, the guest still sees the old XICS interface but
performance is better because the XICS emulation in the host uses the
XIVE directly rather than going through a XICS emulation in firmware.
