The latency of a connection to the PulseAudio server is determined by

A setting of 15ms works fine here. To allow tweaking, I also made the

When VM access registers, QEMU firstly checks whether they have RW
permission, then check whether it is appropriately configured.
If they are defined to read only in EL0, even though they have been
appropriately configured, they still do not have write permission.

target/riscv: Convert to decodetree
Bastian: this patchset converts the RISC-V decoder to decodetree in four major steps:
1) Convert 32-bit instructions to decodetree [Patch 1-15]:
Many of the gen_* functions are called by the decode functions for 16-bit
and 32-bit functions. If we move translation code from the gen_*
functions to the generated trans_* functions of decode-tree, we get a lot of
duplication. Therefore, we mostly generate calls to the old gen_* function
which are properly replaced after step 2).
Each of the trans_ functions are grouped into files corresponding to their
ISA extension, e.g. addi which is in RV32I is translated in the file
'trans_rvi.inc.c'.
2) Convert 16-bit instructions to decodetree [Patch 16-18]:
All 16 bit instructions have a direct mapping to a 32 bit instruction. Thus,
we convert the arguments in the 16 bit trans_ function to the arguments of
the corresponding 32 bit instruction and call the 32 bit trans_ function.
3) Remove old manual decoding in gen_* function [Patch 19-29]:
this move all manual translation code into the trans_* instructions of
decode tree, such that we can remove the old decode_* functions.
Palmer: This, with some additional cleanup patches, passed Alistar's
testing on rv32 and rv64 as well as my testing on rv64, so I think it's
good to go. I've run my standard test against this exact tag.

configure: remove slirp submodule support that doesn't exist yet
The slirp code is not yet split off into a separate repository, so
configuring QEMU to use slirp as a submodule is premature. This
causes the non-existant "slirp" to be requested from git when syncing
submodules. This in turn appears to be cause of non-deterministic

file-posix: add drop-cache=on|off option
Commit dd577a26ff03b6829721b1ffbbf9e7c411b72378 ("block/file-posix:
implement bdrv_co_invalidate_cache() on Linux") introduced page cache
invalidation so that cache.direct=off live migration is safe on Linux.
The invalidation takes a significant amount of time when the file is
large and present in the page cache. Normally this is not the case for
cross-host live migration but it can happen when migrating between QEMU
processes on the same host.
On same-host migration we don't need to invalidate pages for correctness
anyway, so an option to skip page cache invalidation is useful. I
investigated optimizing invalidation and detecting same-host migration,
but both are hard to achieve so a user-visible option will suffice.
As a bonus this option means that the cache invalidation feature will
now be detectable by libvirt via QMP schema introspection.

target/riscv: make ADD/SUB/OR/XOR/AND insn use arg lists
manual decoding in gen_arith() is not necessary with decodetree. For now
the function is called trans_arith as the original gen_arith still
exists. The former will be renamed to gen_arith as soon as the old
gen_arith can be removed.
target/riscv: Move gen_arith_imm() decoding into trans_* functions
gen_arith_imm() does a lot of decoding manually, which was hard to read
in case of the shift instructions and is not necessary anymore with
decodetree.
target/riscv: Convert RV64I load/store insns to decodetree
this splits the 64-bit only instructions into its own decode file such
that we generate the decoder for these instructions only for the RISC-V
64 bit target.

curses: add option to specify VGA font encoding
This uses iconv to convert glyphs from the specified VGA font encoding to
unicode, and makes use of cchar_t instead of chtype when using ncursesw,
which allows to store all wide char as well as the WACS values. The default
charset is made CP437 since that is the charset of the hardware default VGA
font. This also makes the curses backend set the LC_CTYPE locale to "" to
allow curses to emit wide characters.

Before we do device realization and plug, we should allocate necessary
resources and check if memory-hotplug-support property is enabled.
At the piix4 and ich9, the memory-hotplug-support property is checked at
plug stage. This means that device has been realized and mapped into guest
address space 'pc_dimm_plug()' by the time acpi plug handler is called,
where it might fail and crash QEMU due to reaching g_assert_not_reached()
(piix4) or error_abort (ich9).
Fix it by checking if memory hotplug is enabled at pre_plug stage
where we can gracefully abort hotplug request.

gen_pcie_root_port: Add ACS (Access Control Services) capability
Claim ACS support in the generic PCIe root port to allow
passthrough of individual functions of a device to different
guests (in a nested virt.setting) with VFIO.
Without this patch, all functions of a device, such as all VFs of
an SR/IOV device, will end up in the same IOMMU group.
A similar situation occurs on Windows with Hyper-V.
In the single function device case, it also has a small cosmetic
benefit in that the root port itself is not grouped with
the device. VFIO handles that situation in that binding rules
only apply to endpoints, so it does not limit passthrough in
those cases.
