hw: aspeed_gpio: Fix memory size
The macro used to calculate the maximum memory size of the MMIO region
had a mistake, causing all GPIO models to create a mapping of 0x9D8.
The intent was to have it be 0x9D8 - 0x800.
This extra size doesn't matter on ast2400 and ast2500, which have a 4KB
region set aside for the GPIO controller.
On the ast2600 the 3.3V and 1.8V GPIO controllers are 2KB apart, so the
regions would overlap. Worse was the 1.8V controller would map over the
top of the following peripheral, which happens to be the RTC.
The mmio region used by each device is a maximum of 2KB, so avoid the
calculations and hard code this as the maximum.

target/arm: Add missing 'return's after calling v7m_exception_taken()
In do_v7m_exception_exit(), we perform various checks as part of
performing the exception return. If one of these checks fails, the
architecture requires that we take an appropriate exception on the
existing stackframe. We implement this by calling
v7m_exception_taken() to set up to take the new exception, and then
immediately returning from do_v7m_exception_exit() without proceeding
any further with the unstack-and-exception-return process.
In a couple of checks that are new in v8.1M, we forgot the "return"
statement, with the effect that if bad code in the guest tripped over
these checks we would set up to take a UsageFault exception but then
blunder on trying to also unstack and return from the original
exception, with the probable result that the guest would crash.
Add the missing return statements.

target/arm: Enforce that M-profile SP low 2 bits are always zero
For M-profile, unlike A-profile, the low 2 bits of SP are defined to be
RES0H, which is to say that they must be hardwired to zero so that
guest attempts to write non-zero values to them are ignored.
Implement this behaviour by masking out the low bits:
* for writes to r13 by the gdbstub
* for writes to any of the various flavours of SP via MSR
* for writes to r13 via store_reg() in generated code
Note that all the direct uses of cpu_R[] in translate.c are in places
where the register is definitely not r13 (usually because that has
been checked for as an UNDEFINED or UNPREDICTABLE case and handled as
UNDEF).
All the other writes to regs[13] in C code are either:
* A-profile only code
* writes of values we can guarantee to be aligned, such as
- writes of previous-SP-value plus or minus a 4-aligned constant
- writes of the value in an SP limit register (which we already
enforce to be aligned)

hw/nvme: fix controller hot unplugging
Prior to this patch the nvme-ns devices are always children of the
NvmeBus owned by the NvmeCtrl. This causes the namespaces to be
unrealized when the parent device is removed. However, when subsystems
are involved, this is not what we want since the namespaces may be
attached to other controllers as well.
This patch adds an additional NvmeBus on the subsystem device. When
nvme-ns devices are realized, if the parent controller device is linked
to a subsystem, the parent bus is set to the subsystem one instead. This
makes sure that namespaces are kept alive and not unrealized.

accel/tcg: Remove unnecessary check on icount_extra in cpu_loop_exec_tb()
In cpu_loop_exec_tb(), we decide whether to look for a TB with
exactly insns_left instructions in it using the condition
(!cpu->icount_extra && insns_left > 0 && insns_left < tb->icount)
The check for icount_extra == 0 is unnecessary, because we just set
insns_left = MIN(0xffff, cpu->icount_budget);
icount_extra = icount_budget - insns_left;
and so icount_extra can only be non-zero if icount_budget > 0xffff
and insns_left == 0xffff. But in that case insns_left >= tb->icount
because 0xffff is much larger than TCG_MAX_INSNS, so the condition
will be false anyway.
Remove the unnecessary check, and instead assert:
* that we are only going to execute a partial TB here if the
icount budget has run out (ie icount_extra == 0)
* that the number of insns we're going to execute does fit into
the CF_COUNT_MASK

In cpu_loop_exec_tb() we were bounding the number of insns we might
try to execute in a TB using CF_COUNT_MASK. This is incorrect,
because we can validly put up to 0xffff into icount_decr.u16.low. In
particular, since commit
78ff82bb1b67c0d7 reduced CF_COUNT_MASK to
511 this meant that we would incorrectly only try to execute 511
instructions in a 512-instruction TB, which could result in QEMU
hanging when in icount mode.
Use the actual maximum value, which is 0xffff. (This brings this code
in to line with the similar logic in icount_prepare_for_run() in
tcg-accel-ops-icount.c.)

It could mostly happen with postcopy, but that shouldn't be required, e.g., I

migration-test break reported by either Dave or PMM:
https://lore.kernel.org/qemu-devel/YPamXAHwan%2FPPXLf@work-vm/
The issue is: from_dst_file is reset in the rp_thread, so if the thread reset
it to NULL fast enough then the migration thread will assume there's no
rp_thread at all.
This could potentially cause more severe issue (e.g. crash) after the yank code.
Fix it by using a boolean to keep "whether we've created rp_thread".

block/nvme: Fix VFIO_MAP_DMA failed: No space left on device
When the NVMe block driver was introduced (see commit
bdd6a90a9e5,
January 2018), Linux VFIO_IOMMU_MAP_DMA ioctl was only returning
-ENOMEM in case of error. The driver was correctly handling the
error path to recycle its volatile IOVA mappings.
To fix CVE-2019-3882, Linux commit
492855939bdb ("vfio/type1: Limit
DMA mappings per container", April 2019) added the -ENOSPC error to
signal the user exhausted the DMA mappings available for a container.
The block driver started to mis-behave:
qemu-system-x86_64: VFIO_MAP_DMA failed: No space left on device
(qemu)
(qemu) info status
VM status: paused (io-error)
(qemu) c
VFIO_MAP_DMA failed: No space left on device
(qemu) c
VFIO_MAP_DMA failed: No space left on device
(The VM is not resumable from here, hence stuck.)
Fix by handling the new -ENOSPC error (when DMA mappings are
exhausted) without any distinction to the current -ENOMEM error,
so we don't change the behavior on old kernels where the CVE-2019-3882
fix is not present.
An easy way to reproduce this bug is to restrict the DMA mapping
limit (65535 by default) when loading the VFIO IOMMU module:

ui/gtk: add a keyboard fifo to the VTE consoles
Since commit
8eb13bbbac ("ui/gtk: vte: fix sending multiple
characeters") it's very easy to lock up QEMU with the GTK ui.
If you configure a guest with a serial device and the guest
doesn't listen on this device, QEMU will lock up after
entering two characters in the serial console. That's because
current code uses a busy loop for the chardev write retries
and the busy loop doesn't terminate in this case.
To fix this problem add a fifo to the VTE consoles and use the
chr_accept_input() callback function to write the remaining
characters in the queue to the chardev.
The fifo has a size of 4096 bytes, so one can copy and paste
a fairly large URL or file path.

ui/gtk: Fix relative mouse with multiple monitors
To handle relative mouse input the event handler needs to move the mouse
away from the screen edges. Failing to do so results in the mouse
getting stuck at invisible walls. However the current implementation for
this is broken on hosts with multiple monitors.
With multiple monitors the mouse can be located outside of the current
monitor which is not handled by the current code. Also the monitor
itself might be located at coordinates different from (0, 0).

gitlab-ci: Extract OpenSBI job rules to reusable section
All jobs depending on 'docker-opensbi' job must use at most all
the rules that triggers it. The simplest way to ensure that
is to always use the same rules. Extract all the rules to a
reusable section, and include this section (with the 'extends'
keyword) in both 'docker-opensbi' and 'build-opensbi' jobs.
The problem was introduced in commit
c6fc0fc1a71 ("gitlab-ci.yml:
Add jobs to build OpenSBI firmware binaries"), but was revealed in
commit
91e9c47e50a ("docker: OpenSBI build job depends on OpenSBI
container").
This fix is similar to the one used with the EDK2 firmware job in
commit
ac0595cf6b3 ("gitlab-ci: Extract EDK2 job rules to reusable
section").

tests/tcg/configure.sh: add handling for assembler only builds
Up until this point we only handled local compilers or assumed we had
everything in the container. This falls down when we are building QEMU
inside the container.
This special handling only affects tricore for now but I put it in a
case just in case we add any other "special" targets. Setting
CROSS_CC_GUEST is a bit of a hack just to ensure the test runs as we
gate on a detected compiler even though the Makefile won't actually
use it. It also means we display something sane in the configure
output.

qom: use correct field name when getting/setting alias properties
Alias targets have a different name than the alias property itself
(e.g. a machine's pflash0 might be an alias of a property named 'drive').
When the target's getter or setter invokes the visitor, it will use
a different name than what the caller expects, and the visitor will
not be able to find it (or will consume erroneously).
The solution is for alias getters and setters to wrap the incoming
visitor, and forward the sole field that the target is expecting while
renaming it appropriately.
This bug has been there forever, but it was exposed after -M parsing
switched from QemuOptions and StringInputVisitor to keyval and
QObjectInputVisitor. Before, the visitor ignored the name. Now, it
checks "drive" against what was passed on the command line and finds
that no such property exists.

qapi: introduce forwarding visitor
This new adaptor visitor takes a single field of the adaptee, and exposes it
with a different name.
This will be used for QOM alias properties. Alias targets can of course
have a different name than the alias property itself (e.g. a machine's
pflash0 might be an alias of a property named 'drive'). When the target's

gitlab: only let pages be published from default branch
GitLab will happily publish pages generated by the latest CI pipeline
from any branch:
https://docs.gitlab.com/ee/user/project/pages/introduction.html
"Remember that GitLab Pages are by default branch/tag agnostic
and their deployment relies solely on what you specify in
.gitlab-ci.yml. You can limit the pages job with the only
parameter, whenever a new commit is pushed to a branch used
specifically for your pages."
The current "pages" job is not limited, so it is happily publishing
docs content from any branch/tag in qemu.git that gets pushed to.
This means we're potentially publishing from the "staging" branch
or worse from outdated "stable-NNN" branches
This change restricts it to only publish from the default branch
in the main repository. For contributor forks, however, we allow
it to publish from any branch, since users will have arbitrarily
named topic branches in flight at any time.

i386: do not call cpudef-only models functions for max, host, base
Some cpu properties have to be set only for cpu models in builtin_x86_defs,
registered with x86_register_cpu_model_type, and not for
cpu models "base", "max", and the subclass "host".
These properties are the ones set by function x86_cpu_apply_props,
(also including kvm_default_props, tcg_default_props),
and the "vendor" property for the KVM and HVF accelerators.
After recent refactoring of cpu, which also affected these properties,
they were instead set unconditionally for all x86 cpus.
This has been detected as a bug with Nested on AMD with cpu "host",
as svm was not turned on by default, due to the wrongful setting of
kvm_default_props via x86_cpu_apply_props, which set svm to "off".
Rectify the bug introduced in commit "i386: split cpu accelerators"
and document the functions that are builtin_x86_defs-only.
