linux-user: Fix syscall parameter handling for MIPS n32
The MIPS n32 ABI is basically n64 with the address space (i.e. pointer
width) shrinked to 32 bits. Meanwhile the current code treats it as
o32-like based on TARGET_ABI_BITS, which causes problems with n32
syscalls utilizing 64-bit offsets, like pread64, affecting most (if not
all) recently built n32 binaries.
This partially solves issue #909 ("qemu-mipsn32(el) user mode emulator
fails to execute any recently built n32 binaries"); with this change
applied, the built qemu-mipsn32el is able to progress beyond the
pread64, and finish _dl_start_user for the "getting ld.so load libc.so"
case. The program later dies with SIGBUS, though, due to _dl_start_user
not maintaining stack alignment after removing ld.so itself from argv,
and qemu-user starting to enforce alignment recently, but that is
orthogonal to the issue here; the more common case of chrooting is
working, verified with my own-built Gentoo n32 sysroot. (Depending on
the exact ISA used, one may have to explicitly specify QEMU_CPU, which
is the case for my chroot.)

target/i386: kvm: do not access uninitialized variable on older kernels

Commit
19db68ca68 ("x86: Grant AMX permission for guest", 2022-03-15) however
did not fully consider the behavior on older kernels. First, it warns
too aggressively. Second, it invokes the KVM_GET_DEVICE_ATTR ioctl
unconditionally and then uses the "bitmask" variable, which remains
uninitialized if the ioctl fails. Third, kvm_ioctl returns -errno rather
than -1 on errors.
While at it, explain why the ioctl is needed and KVM_GET_SUPPORTED_CPUID
is not enough.

util/osdep: Avoid madvise proto on modern Solaris
On older Solaris releases (before Solaris 11), we didn't get a
prototype for madvise, and so util/osdep.c provides its own prototype.
Some time between the public Solaris 11.4 release and Solaris 11.4.42
CBE, we started getting an madvise prototype that looks like this:
extern int madvise(void *, size_t, int);
which conflicts with the prototype in util/osdeps.c. Instead of always
declaring this prototype, check if we're missing the madvise()
prototype, and only declare it ourselves if the prototype is missing.
Move the prototype to include/qemu/osdep.h, the normal place to handle
platform-specific header quirks.
The 'missing_madvise_proto' meson check contains an obviously wrong
prototype for madvise. So if that code compiles and links, we must be
missing the actual prototype for madvise.

about loads from the vector table. Add logging where we load vector

has accidentally not put a vector table in their image at all, which
can result in confusing guest crashes at startup.
Here's an example of the new logging for a case where
the vector table contains garbage:
Loaded reset SP 0x0 PC 0x0 from vector table
Loaded reset SP 0xd008f8df PC 0xf000bf00 from vector table

nsis installer: Fix mouse-over descriptions for emulators
We use the nsis.py script to write out an installer script Section
for each emulator executable, so the exact set of Sections depends on
which executables were built. However the part of qemu.nsi which
specifies mouse-over descriptions for each Section still has a
hard-coded and very outdated list (with just i386 and alpha). This
causes two problems. Firstly, if you build the installer for a
configuration where you didn't build the i386 binaries you get
warnings like this:
warning 6000: unknown variable/constant "{Section_i386}" detected, ignoring (macro:_==:1)
warning 6000: unknown variable/constant "{Section_i386w}" detected, ignoring (macro:_==:1)
(this happens in our gitlab CI jobs, for instance).
Secondly, most of the emulators in the generated installer don't have
any mouseover text.
Make nsis.py generate a second output file which has the necessary
MUI_DESCRIPTION_TEXT lines for each Section it creates, so we can
include that at the right point in qemu.nsi to set the mouse-over
text.

target/arm: Fix handling of LPAE block descriptors
LPAE descriptors come in three forms:
* table descriptors, giving the address of the next level page table
* page descriptors, which occur only at level 3 and describe the
mapping of one page (which might be 4K, 16K or 64K)
* block descriptors, which occur at higher page table levels, and
describe the mapping of huge pages
QEMU's page-table-walk code treats block and page entries
identically, simply ORing in a number of bits from the input virtual
address that depends on the level of the page table that we stopped
at; we depend on the previous masking of descaddr with descaddrmask
to have already cleared out the low bits of the descriptor word.
This is not quite right: the address field in a block descriptor is
smaller, and so there are bits which are valid address bits in a page
descriptor or a table descriptor but which are not supposed to be
part of the address in a block descriptor, and descaddrmask does not
clear them. We previously mostly got away with this because those
descriptor bits are RES0; however with FEAT_BBM (part of Armv8.4)
block descriptor bit 16 is defined to be the nT bit. No emulated
QEMU CPU has FEAT_BBM yet, but if the host CPU has it then we might
see it when using KVM or hvf.
Explicitly zero out all the descaddr bits we're about to OR vaddr
bits into.

target/arm: Fix sve2 ldnt1 and stnt1
For both ldnt1 and stnt1, the meaning of the Rn and Rm are different
from ld1 and st1: the vector and integer registers are reversed, and
the integer register 31 refers to XZR instead of SP.
Secondly, the 64-bit version of ldnt1 was being interpreted as
32-bit unpacked unscaled offset instead of 64-bit unscaled offset,
which discarded the upper 32 bits of the address coming from
the vector argument.
Thirdly, validate that the memory element size is in range for the
vector element size for ldnt1. For ld1, we do this via independent
decode patterns, but for ldnt1 we need to do it manually.

hw/display/vga: Report a proper error when adding a 2nd ISA VGA
QEMU currently abort()s if the user tries to add a second ISA VGA
device, for example:
$ ./qemu-system-x86_64 -device isa-vga -device isa-vga
RAMBlock "vga.vram" already registered, abort!
Aborted (core dumped)
$ ./qemu-system-x86_64 -device isa-cirrus-vga -device isa-cirrus-vga

Aborted (core dumped)
$ ./qemu-system-mips64el -M pica61 -device isa-vga
RAMBlock "vga.vram" already registered, abort!

Such a crash should never happen just because of giving bad parameters
at the command line. Let's return a proper error message instead.
(The idea is based on an original patch by Jose R. Ziviani for the
isa-vga device, but this now fixes it for the isa-cirrus-vga device, too)

aio-posix: fix spurious ->poll_ready() callbacks in main loop
When ->poll() succeeds the AioHandler is placed on the ready list with
revents set to the magic value 0. This magic value causes
aio_dispatch_handler() to invoke ->poll_ready() instead of ->io_read()
for G_IO_IN or ->io_write() for G_IO_OUT.
This magic value 0 hack works for the IOThread where AioHandlers are
placed on ->ready_list and processed by aio_dispatch_ready_handlers().
It does not work for the main loop where all AioHandlers are processed
by aio_dispatch_handlers(), even those that are not ready and have a
revents value of 0.
As a result the main loop invokes ->poll_ready() on AioHandlers that are
not ready. These spurious ->poll_ready() calls waste CPU cycles and
could lead to crashes if the code assumes ->poll() must have succeeded
before ->poll_ready() is called (a reasonable asumption but I haven't
seen it in practice).
Stop using revents to track whether ->poll_ready() will be called on an
AioHandler. Introduce a separate AioHandler->poll_ready field instead.
This eliminates spurious ->poll_ready() calls in the main loop.

ui/cocoa: add option to swap Option and Command
On Mac OS X the Option key maps to Alt and Command to Super/Meta. This change
swaps them around so that Alt is the key closer to the space bar and Meta/Super
is between Control and Alt, like on non-Mac keyboards.
It is a cocoa display option, disabled by default.

ui/cocoa: capture all keys and combos when mouse is grabbed
Applications such as Gnome may use Alt-Tab and Super-Tab for different
purposes, some use Ctrl-arrows so we want to allow qemu to handle
everything when it captures the mouse/keyboard.
However, Mac OS handles some combos like Command-Tab and Ctrl-arrows
at an earlier part of the event handling chain, not letting qemu see it.
We add a global Event Tap that allows qemu to see all events when the
mouse is grabbed. Note that this requires additional permissions.

ui/cocoa: release mouse when user switches away from QEMU window
This resolves an issue where using command-tab to switch between QEMU

By releasing the mouse when the user switches away, the user must left
click on the QEMU window when switching back in order to hide the
pointer and return control to the guest.
This appraoch ensures that the calls to NSCursor hide and unhide are
always balanced and thus work correctly when invoked.

Kernel allocates 4K xstate buffer by default. For XSAVE features
which require large state component (e.g. AMX), Linux kernel
dynamically expands the xstate buffer only after the process has

enabled XSAVE features (or dynamic xfeatures).
There are separate permissions for native tasks and guests.
Qemu should request the guest permissions for dynamic xfeatures
which will be exposed to the guest. This only needs to be done
once before the first vcpu is created.
KVM implemented one new ARCH_GET_XCOMP_SUPP system attribute API to
get host side supported_xcr0 and Qemu can decide if it can request
dynamically enabled XSAVE features permission.
