c11b3a1dd3 docs/sphinx: change default role to "any"
This interprets single-backtick syntax in all of our Sphinx docs as a
cross-reference to *something*, including Python symbols.

From here on out, new uses of `backticks` will cause a build failure if
the target cannot be referenced.

450e0f28a4 docs: remove non-reference uses of single backticks
The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.

This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.

Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.

e86a93f554 virtio-gpu: splitting one extended mode guest fb into n-scanouts
When guest is running Linux/X11 with extended multiple displays mode enabled,
the guest shares one scanout resource each time containing whole surface
rather than sharing individual display output separately. This extended frame
is properly splited and rendered on the corresponding scanout surfaces but
not in case of blob-resource (zero copy).

This code change lets the qemu split this one large surface data into multiple
in case of blob-resource as well so that each sub frame then can be blitted
properly to each scanout.

v2: resizing qemu console in virtio_gpu_update_dmabuf to scanout's width and
    height

v3: updating stub function of virtio_gpu_update_dmabuf to match the type

25ddb946e6 e1000: fix tx re-entrancy problem
The fact that the MMIO handler is not re-entrant causes an infinite
loop under certain conditions:

Guest write to TDT ->  Loopback -> RX (DMA to TDT) -> TX

We now eliminate the effect of this problem locally in e1000, by adding
a boolean in struct E1000State indicating when the TX side is busy. This
will cause any entering new call to return early instead of interfering
with the ongoing work, and eliminates any risk of looping.

This is intended to address CVE-2021-20257.

This series adds support for the Hexagon Vector eXtensions (HVX)

These instructions are documented here
https://developer.qualcomm.com/downloads/qualcomm-hexagon-v66-hvx-programmer-s-reference-manual

Hexagon HVX is a wide vector engine with 128 byte vectors.

See patch 01 Hexagon HVX README for more information.

*** Changes in v2 ***
Remove HVX tests from makefile to avoid need for toolchain upgrade

357af9be5c plugins: try and make plugin_insn_append more ergonomic
Currently we make the assumption that the guest frontend loads all
op code bytes sequentially. This mostly holds up for regular fixed
encodings but some architectures like s390x like to re-read the
instruction which causes weirdness to occur. Rather than changing the
frontends make the plugin API a little more ergonomic and able to
handle the re-read case.

Stuff will still get strange if we read ahead of the opcode but so far
no front ends have done that and this patch asserts the case so we can
catch it early if they do.

a00e37a4be chardev: don't exit() straight away on C-a x
While there are a number of uses in the code-base of the exit(0)
pattern it gets in the way of clean exit which can do all of it's
house-keeping. In particular it was reported that you can crash
plugins this way because TCG can still be running on other threads
when the atexit callback is called.

Use qmp_quit() instead which takes care of some housekeeping before
triggering the shutdown.

b8312e04c8 docs/tcg-plugins: add L2 arguments to cache docs
cache plugin now allows optional L2 per-core cache emulation that can be
configured through plugin arguments, this commit adds this functionality
to the docs.

While I'm at it, I editted the bullet point for cache plugin to say:
    contrib/plugins/cache.c
instead of
    contrib/plugins/cache
to match other plugins.

14f3110a99 plugins/cache: implement unified L2 cache emulation
This adds an implementation of a simple L2 configuration, in which a
unified L2 cache (stores both blocks of instructions and data) is
maintained for each core separately, with no inter-core interaction
taken in account. The L2 cache is used as a backup for L1 and is only
accessed if the wanted block does not exist in L1.

In terms of multi-threaded user-space emulation, the same approximation
of L1 is done, a static number of caches is maintained, and each and
every memory access initiated by a thread will have to go through one of
the available caches.

An atomic increment is used to maintain the number of L2 misses per
instruction.

The default cache parameters of L2 caches is:

    2MB cache size
    16-way associativity
    64-byte blocks
