The value previously chosen overlaps GUSA_MASK.

Rename all DELAY_SLOT_* and GUSA_* defines to emphasize

tcg/ppc: Optimize 26-bit jumps

PowerPC64 processors handle direct branches better than indirect
ones, resulting in less stalled cycles and branch misses.

However, PPC's tb_target_set_jmp_target() was only using direct
branches for 16-bit jumps, while PowerPC64's unconditional branch
instructions are able to handle displacements of up to 26 bits.
To take advantage of this, now jumps whose displacements fit in
between 17 and 26 bits are also converted to direct branches.

accel/tcg: Use DisasContextBase in plugin_gen_tb_start

Use the pc coming from db->pc_first rather than the TB.

Use the cached host_addr rather than re-computing for the
first page.  We still need a separate lookup for the second
page because it won't be computed for DisasContextBase until
the translator actually performs a read from the page.

Use g_new() & friends where that makes obvious sense

g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch

Hexagon (gen_tcg_funcs.py): avoid duplicated tcg code on A_CVI_NEW

Hexagon instructions with the A_CVI_NEW attribute produce a vector value
that can be used in the same packet. The python function responsible for
generating code for such instructions has a typo ("if" instead of
"elif"), which makes genptr_dst_write_ext() be executed twice, thus also
generating the same tcg code twice. Fortunately, this doesn't cause any
problems for correctness, but it is less efficient than it could be. Fix
it by using an "elif" and avoiding the unnecessary extra code gen.

x86: re-initialize RNG seed when selecting kernel

We don't want it to be possible to re-read the RNG seed after ingesting
it, because this ruins forward secrecy. Currently, however, the setup
data section can just be re-read. Since the kernel is always read after
the setup data, use the selection of the kernel as a trigger to
re-initialize the RNG seed, just like we do on reboot, to preserve
forward secrecy.

configure, meson: move C++ compiler detection to meson.build

The test is slightly weaker than before, because it does not
call an extern "C" function from a C source file.  However,
in practice what we seek to detect is ABI compatibility of the

anything with CC and link it with CXX.

Hexagon (target/hexagon) move store size tracking to translation

The store width is needed for packet commit, so it is stored in
ctx->store_width.  Currently, it is set when a store has a TCG
override instead of a QEMU helper.  In the QEMU helper case, the
ctx->store_width is not set, we invoke a helper during packet commit
that uses the runtime store width.

This patch ensures ctx->store_width is set for all store instructions,
so performance is improved because packet commit can generate the proper
TCG store rather than the generic helper.

- Use the attributes from the instructions during translation to
  set ctx->store_width
- Remove setting of ctx->store_width from genptr.c

block/qcow2: Keep auto_backing_file if possible

qcow2_do_open() is used by qcow2_co_invalidate_cache(), i.e. may be run
on an image that has been opened before.  When reading the backing file
string from the image header, compare it against the existing
bs->backing_file, and update bs->auto_backing_file only if they differ.

auto_backing_file should ideally contain the filename the backing BDS
will actually have after opening, i.e. a post-bdrv_refresh_filename()
version of what is in the image header.  So for example, if the image
header reports the following backing file string:

    json:{"driver": "qcow2", "file": {
        "driver": "file", "filename": "/tmp/backing.qcow2"
    }}

Then auto_backing_file should contain simply "/tmp/backing.qcow2".

Because bdrv_refresh_filename() only works on existing BDSs, though, the
way how we get this auto_backing_file value is to have the format driver
set it to whatever is in the image header, and when the backing BDS is
opened based on that, we update it with the filename the backing BDS
actually got.

However, qcow2's qcow2_co_invalidate_cache() implementation breaks this
because it just resets auto_backing_file to whatever is in the image
file without opening a BDS based on it, so we never get
auto_backing_file back to the "refreshed" version, and in the example
above, it would stay "json:{...}".

Then, bs->backing->bs->filename will differ from bs->auto_backing_file,
making bdrv_backing_overridden(bs) return true, which will lead
bdrv_refresh_filename(bs) to generate a json:{} filename for bs, even
though that may not have been necessary.  This is reported in the issue
linked below.

Therefore, skip updating auto_backing_file if nothing has changed in the
image header since we last read it.

gluster: stop using .bdrv_needs_filename

The gluster protocol driver used to parse URIs (filenames) but was

("block/gluster: add support for multiple gluster servers"). The gluster

even though the JSON parser is equipped to parse the same
volume/path/sockaddr details as the URI parser. Let's allow JSON parsing
for these drivers too.

Note that the gluster+rdma driver actually uses TCP because RDMA support
is not available, so the JSON server.type field must be "inet".

Drop .bdrv_needs_filename since both the filename and the JSON parsers
can handle gluster+unix and gluster+rdma. This change is in preparation
for eventually removing .bdrv_needs_filename across the entire codebase.

* block_acct_setup() inside blockdev_init() is called before

hw/arm/virt: Use "msi-map" devicetree property for PCI

The "msi-parent" property can be used on the PCI node when MSIs do not
contain sideband data (device IDs) [1]. In QEMU, MSI transactions
contain the requester ID, so the PCI node should use the "msi-map"
property instead of "msi-parent". In our case the property describes an
identity map between requester ID and sideband data.

This fixes a warning when passing the DTB generated by QEMU to dtc,
following a recent change to the GICv3 node:

cpu64.c has ended up in a slightly odd order -- it starts with the
initfns for most of the models-real-hardware CPUs; after that comes a
bunch of support code for SVE, SME, pauth and LPA2 properties.  Then

that one more models-real-hardware CPU initfn, for a64fx.  (This
ordering is partly historical and partly required because a64fx needs
the SVE properties.)

target/arm: Update SDCR_VALID_MASK to include SCCD

by the current architecture.  In particular in commit 0b42f4fab9d3 we
forgot to add SCCD, which meant that an AArch32 guest couldn't
actually use the SCCD bit to disable counting in Secure state.

Add all the currently defined bits; we don't implement all of them,

valid and matches how we currently handle most of the others in the

target/arm: Make writes to MDCR_EL3 use PMU start/finish calls

In commit 01765386a88868 we fixed a bug where we weren't correctly
bracketing changes to some registers with pmu_op_start() and
pmu_op_finish() calls for changes which affect whether the PMU
counters might be enabled.  However, we missed the case of writes to
the AArch64 MDCR_EL3 register, because (unlike its AArch32
counterpart) they are currently done directly to the CPU state struct
without going through the sdcr_write() function.

Give MDCR_EL3 a writefn which handles the PMU start/finish calls.
The SDCR writefn then simplfies to "call the MDCR_EL3 writefn after
masking off the bits which don't exist in the AArch32 register".
