Jeff Cody 03283d6433 MAINTAINERS: Replace myself with John Snow for block jobs
I'll not be involved with day-to-day qemu development, and John
Snow is a block jobs wizard.  Have him take over block job
maintainership duties.

Marc-André Lureau d8aec9d9f1 display: add -display spice-app launching a Spice client
Add a new display backend that will configure Spice to allow a remote
client to control QEMU in a similar fashion as other QEMU display
backend/UI like GTK.

For this to work, it will set up Spice server with a unix socket, and
register a VC chardev that will be exposed as Spice ports. A QMP
monitor is also exposed as a Spice port, this allows the remote client
fuller qemu control and state handling.

- doesn't handle VC set_echo() - this doesn't seem a strong
  requirement, very few front-end use it
- spice options can be tweaked with other -spice arguments
- Windows support shouldn't be hard to do, but will probably use a TCP
  port instead
- we may want to watch the child process to quit automatically if it
  crashed

Eric Auger 2b6326c0bf hw/vfio/common: Refactor container initialization
We introduce the vfio_init_container_type() helper.
It computes the highest usable iommu type and then
set the container and the iommu type.

Its usage in vfio_connect_container() makes the code
ready for addition of new iommu types.

Alex Williamson 567d7d3e6b vfio/common: Work around kernel overflow bug in DMA unmap
A kernel bug was introduced in v4.15 via commit 71a7d3d78e3c which
adds a test for address space wrap-around in the vfio DMA unmap path.
Unfortunately due to overflow, the kernel detects an unmap of the last
page in the 64-bit address space as a wrap-around.  In QEMU, a Q35
guest with VT-d emulation and guest IOMMU enabled will attempt to make
such an unmap request during VM system reset, triggering an error:

  qemu-kvm: VFIO_UNMAP_DMA: -22
  qemu-kvm: vfio_dma_unmap(0x561f059948f0, 0xfef00000, 0xffffffff01100000) = -22 (Invalid argument)

Here the IOVA start address (0xfef00000) and the size parameter
(0xffffffff01100000) add to exactly 2^64, triggering the bug.  A
kernel fix is queued for the Linux v5.0 release to address this.

This patch implements a workaround to retry the unmap, excluding the
final page of the range when we detect an unmap failing which matches
the requirements for this issue.  This is expected to be a safe and
complete workaround as the VT-d address space does not extend to the
full 64-bit space and therefore the last page should never be mapped.

This workaround can be removed once all kernels with this bug are
sufficiently deprecated.

BALATON Zoltan fb1b0fcc03 target/mips: fulong2e: Dynamically generate SPD EEPROM data
The machine comes with 256M memory module by default but it's
upgradable so it could have different memory size. There was a TODO
comment to replace static SPD EEPROM data with dynamically generated
one to support this. Now that we have a function for that, it's easy
to do. Although this would allow larger RAM sizes, the peculiar memory
map of the machine may need some special handling to map it as low and
high memory. Because I don't know what the correct place would be for
highmem, I've left memory size fixed at 256M for now and TODO is moved
there instead.

David Hildenbrand 8c6edfdd90 include/exec/helper-head.h: support "const void *" in helper calls
Especially when dealing with out-of-line gvec helpers, it is often
helpful to specify some vector pointers as constant. E.g. when
we have two inputs and one output, marking the two inputs as consts
pointers helps to avoid bugs.

Const pointers can be specified via "cptr", however behave in TCG just
like ordinary pointers. We can specify helpers like:

DEF_HELPER_FLAGS_4(gvec_vbperm, TCG_CALL_NO_RWG, void, ptr, cptr, cptr, i32)

void HELPER(gvec_vbperm)(void *v1, const void *v2, const void *v3,
                         uint32_t desc)

And make sure that here, only v1 will be written (as long as const is
not casted away, of course).

Peter Maydell 3733f80308 hw/arm/armsse: Make 0x5... alias region work for per-CPU devices
The region 0x40010000 .. 0x4001ffff and its secure-only alias
at 0x50010000... are for per-CPU devices. We implement this by
giving each CPU its own container memory region, where the
per-CPU devices live. Unfortunately, the alias region which
makes devices mapped at 0x4... addresses also appear at 0x5...
is only implemented in the overall "all CPUs" container. The
effect of this bug is that the CPU_IDENTITY register block appears
only at 0x4001f000, but not at the 0x5001f000 alias where it should
also appear. Guests (like very recent Arm Trusted Firmware-M)
which try to access it at 0x5001f000 will crash.

Fix this by moving the handling for this alias from the "all CPUs"
container to the per-CPU container. (We leave the aliases for
0x1... and 0x3... in the overall container, because there are
no per-CPU devices there.)

Peter Maydell 37e571f1e0 hw/misc/tz-ppc: Support having unused ports in the middle of the range
The Peripheral Protection Controller's handling of unused ports
is that if there is nothing connected to the port's downstream
then it does not create the sysbus MMIO region for the upstream
end of the port. This results in odd behaviour when there is
an unused port in the middle of the range: since sysbus MMIO
regions are implicitly consecutively allocated, any used ports
above the unused ones end up with sysbus MMIO region numbers
that don't match the port number.

Avoid this numbering mismatch by creating dummy MMIO regions
for the unused ports. This doesn't change anything for our
existing boards, which don't have any gaps in the middle of
the port ranges they use; but it will be needed for the Musca
board.

Peter Maydell cff21316c6 target/arm: v8M MPU should use background region as default, not always
The "background region" for a v8M MPU is a default which will be used
(if enabled, and if the access is privileged) if the access does
not match any specific MPU region. We were incorrectly using it
always (by putting the condition at the wrong nesting level). This
meant that we would always return the default background permissions
rather than the correct permissions for a specific region, and also
that we would not return the right information in response to a
TT instruction.

Move the check for the background region to the same place in the
logic as the equivalent v8M MPUCheck() pseudocode puts it.
This in turn means we must adjust the condition we use to detect
matches in multiple regions to avoid false-positives.
