7969cf4639 vfio/igd: Remove generation limitation for IGD passthrough
Starting from Intel Core Ultra Series (Meteor Lake), Data Stolen Memory
has became a part of LMEMBAR (MMIO BAR2) [1][2], meaning that BDSM and
GGC register quirks are no longer needed on these platforms.

To support Meteor/Arrow/Lunar Lake and future IGD devices, remove the
generation limitation in IGD passthrough, and apply BDSM and GGC quirks
only to known Gen6-12 devices.

16cbb43302 vfio/igd: Enable OpRegion by default
As the presence of OpRegion is used to detect IGD device now, and
guest driver usually depends on OpRegion to work. Enable OpRegion
on IGD devices by default for out-of-the-box passthrough experience
(except pre-boot display output), especially for libvirt users.

Example of IGD passthrough with libvirt:
<hostdev mode="subsystem" type="pci" managed="yes">
  <source>
    <address domain="0x0000" bus="0x00" slot="0x02" function="0x0"/>
  </source>
  <rom file="/path/to/igd/rom"/>
  <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0"/>
 </hostdev>

106cdbcef4 vfio/igd: Check OpRegion support on GVT-g mdev
The Intel GVT-g backend `kvmgt` always emulates OpRegion for vGPU,
make sure the OpRegion is present for enabling access to it
automatically later.

Also, hotplugging GVT-g vGPU is now always disallowed regardless of
OpRegion to prevent potential issues. Intel has never claimed support
for GVT-g hotplugging.

2bd33abcf1 vfio/igd: Check vendor and device ID on GVT-g mdev
Check the vendor and device ID on GVT-g mdev to ensure it is a supported
device [1]. This extra check is required for automatically enabling
OpRegion access later.

Note that Cherryview and Gemini Lake are marked as supported here since
current code cannot distinguish them with other Gen8 and Gen9 devices.
Since mdev cannot be created on these devices, this has no functional
impact.

graphics device is IGD or discrete GPU. However, only IGD devices have
OpRegion. Use the presence of VFIO_REGION_SUBTYPE_INTEL_IGD_OPREGION

1d5f84f349 vfio/igd: Always emulate ASLS (OpRegion) register
ASLS register represents the base address of OpRegion, and it is
programmed with HPA. In IGD passthrough scenario, it needs to be
reprogrammed with GPA by guest firmware. To prevent guest accessing
wrong memory range, ASLS should always be emulated and cleared.

In GVT-g scenario, emulating ASLS is unnecessary as access is handled
by kvmgt backend [1].

dd69d84604 vfio/igd: Restrict legacy mode to Gen6-9 devices
Intel only provides legacy VBIOS for IGD up to Gen9, and there is no
CSM support on later devices. Additionally, Seabios can only handle
32-bit BDSM register used until Gen9. Since legacy mode requires VGA
capability, restrict it to Gen6 through Gen9 devices.

4b1f5b73e0 tests/functional: Use -no-shutdown in the hppa_seabios test
qemu-system-hppa shuts down automatically when the BIOS is
unable to boot from any device. So this test currently fails
occasionally when QEMU already quit, but the test still
expected it to be around (e.g. to shut it down cleanly).
Adding a "-no-shutdown" seems to make it reliable.
While we're at it, also remove the stray "self.machine" in
there that does not have any purpose.

eba837a31b hw/gpio/imx_gpio: Fix interpretation of GDIR polarity
According to the i.MX 8M Plus reference manual, a GPIO pin is
configured as an output when the corresponding bit in the GDIR
register is set.  The function imx_gpio_set_int_line() is intended to
be a no-op if the pin is configured as an output, returning early in
such cases.  However, it inverts the condition.  Fix this by
returning early when the bit is set.

d3a161cdd5 target/arm/kvm: Drop support for kernels without KVM_ARM_PREFERRED_TARGET
Our KVM code includes backwards compatibility support for ancient
kernels which don't support the KVM_ARM_PREFERRED_TARGET ioctl.  This
ioctl was introduced in kernel commit 42c4e0c77ac91 in September
2013 and is in v3.12, so it's reasonable to assume it's present.

(We already dropped support for kernels without KVM_CAP_DEVICE_CTRL,
a feature added to the kernel in April 2013, in our commit
84f298ea3e; so there are only about six months' worth of kernels,
from v3.9 to v3.11, that we don't already fail to run on and that
this commit is dropping handling for.)

82707dd4f0 docs: Don't define duplicate label in qemu-block-drivers.rst.inc
Sphinx requires that labels within documents are unique across the
whole manual.  This is because the "create a hyperlink" directive
specifies only the name of the label, not a filename+label.  Some
Sphinx versions will warn about duplicate labels, but even if there
is no warning there is still an ambiguity and no guarantee that the
hyperlink will be created to the right target.

For QEMU this is awkward, because we have various .rst.inc fragments
which we include into multiple .rst files.  If you define a label in
the .rst.inc file then it will be a duplicate label.  We have mostly
worked around this by not putting labels into those .rst.inc files,
or by adding "insert a label" functionality into the hxtool extension
(see commit 1eeb432a95 "doc/sphinx/hxtool.py: add optional label
argument to SRST directive").

Unfortunately in commit 7f6314427e ("docs/devel: add a codebase
section") we accidentally added a duplicate label, because not all
Sphinx versions warn about the mistake.

In this case the link was only from the developer docs codebase
summary, so as the simplest fix for the stable branch, we drop
the link entirely.

8ed7c0b648 target/arm: Don't assert() for ISB/SB inside IT block
If the guest code has an ISB or SB insn inside an IT block, we
generate incorrect code which trips a TCG assertion:

qemu-system-arm: ../tcg/tcg-op.c:3343: void tcg_gen_goto_tb(unsigned int): Assertion `(tcg_ctx->goto_tb_issue_mask & (1 << idx)) == 0' failed.

This is because we call gen_goto_tb(dc, 1, ...) twice:

 brcond_i32 ZF,$0x0,ne,$L1
 add_i32 pc,pc,$0x4
 goto_tb $0x1
 exit_tb $0x73d948001b81
 set_label $L1
 add_i32 pc,pc,$0x4
 goto_tb $0x1
 exit_tb $0x73d948001b81

Both calls are in arm_tr_tb_stop(), one for the
DISAS_NEXT/DISAS_TOO_MANY handling, and one for the dc->condjump
condition-failed codepath.  The DISAS_NEXT handling doesn't have this
problem because arm_post_translate_insn() does the handling of "emit
the label for the condition-failed conditional execution" and so
arm_tr_tb_stop() doesn't have dc->condjump set.  But for
DISAS_TOO_MANY we don't do that.

Fix the bug by making arm_post_translate_insn() handle the
DISAS_TOO_MANY case.  This only affects the SB and ISB insns when
used in Thumb mode inside an IT block: only these insns specifically
set is_jmp to TOO_MANY, and their A32 encodings are unconditional.

For the major TOO_MANY case (breaking the TB because it would cross a
page boundary) we do that check and set is_jmp to TOO_MANY only after
the call to arm_post_translate_insn(); so arm_post_translate_insn()
sees is_jmp == DISAS_NEXT, and  we emit the correct code for that
situation.

With this fix we generate the somewhat more sensible set of TCG ops:
 brcond_i32 ZF,$0x0,ne,$L1
 set_label $L1
 add_i32 pc,pc,$0x4
 goto_tb $0x1
 exit_tb $0x7c5434001b81

(NB: the TCG optimizer doesn't optimize out the jump-to-next, but
we can't really avoid emitting it because we don't know at the
point we're emitting the handling for the condexec check whether
this insn is going to happen to be a nop for us or not.)

8e72b0eb18 util: exclude mmap-alloc.c from compilation target on Emscripten
Emscripten does not support partial unmapping of mmapped memory
regions[1]. This limitation prevents correct implementation of qemu_ram_mmap
and qemu_ram_munmap, which rely on partial unmap behavior.

As a workaround, this commit excludes mmap-alloc.c from the Emscripten
build. Instead, for Emscripten build, this modifies qemu_anon_ram_alloc to
use qemu_memalign in place of qemu_ram_mmap, and disable memory backends
that rely on mmap, such as memory-backend-file and memory-backend-shm.

0f46bf659f include/qemu/osdep.h: Add Emscripten-specific OS dependencies
On emscripten, some implementations in os-posix.c can't be used such as
daemonizing and changing user. This commit introduces os-wasm.c and
os-wasm.h which are forked from os-posix.c and os-posix.h and patched for
targetting Emscripten.

208808242f block: Fix type conflict of the copy_file_range stub
Emscripten doesn't provide copy_file_range implementation but it declares
this function in its headers. Meson correctly detects the missing
implementation and unsets HAVE_COPY_FILE_RANGE. However, the stub defined in
file-posix.c causes a type conflict with the declaration from Emscripten
during compilation.

To fix this error, this commit updates the stub implementation in
file-posix.c to exactly match the declaration in Emscripten's headers. The
manpage also aligns with this signature.

4c7c051719 util/cacheflush.c: Update cache flushing mechanism for Emscripten
Although __builtin___clear_cache is used to flush the instruction cache for
a specified memory region, this operation doesn't apply to wasm, as its
memory isn't executable. Moreover, Emscripten does not support this builtin
and fails to compile it with the following error.

> fatal error: error in backend: llvm.clear_cache is not supported on wasm

To resolve this, this commit removes the call to __builtin___clear_cache for
Emscripten build.

4cd5a25557 include/glib-compat.h: Poison g_list_sort and g_slist_sort
On Emscripten, function pointer casts can result in runtime failures due to
strict function signature checks. This affects the use of g_list_sort and
g_slist_sort, which internally perform function pointer casts that are not
supported by Emscripten. To avoid these issues, g_list_sort_with_data and
g_slist_sort_with_data should be used instead, as they do not rely on
function pointer casting.
