c1087f1206 block: Add bdrv_child_refresh_perms()
If a block node uses bdrv_child_try_set_perm() to change the permission
it takes on its child, the result may be very short-lived.  If anything
makes the block layer recalculate the permissions internally, it will
invoke the node driver's .bdrv_child_perm() implementation.  The
permission/shared permissions masks that returns will then override the
values previously passed to bdrv_child_try_set_perm().

If drivers want a child edge to have specific values for the
permissions/shared permissions mask, it must return them in
.bdrv_child_perm().  Consequentially, there is no need for them to pass
the same values to bdrv_child_try_set_perm() then: It is better to have
a function that invokes .bdrv_child_perm() and calls
bdrv_child_try_set_perm() with the result.  This patch adds such a
function under the name of bdrv_child_refresh_perms().

094e363944 file-posix: Update open_flags in raw_set_perm()
raw_check_perm() + raw_set_perm() can change the flags associated with
the current FD.  If so, we have to update BDRVRawState.open_flags
accordingly.  Otherwise, we may keep reopening the FD even though the
current one already has the correct flags.

b23c580c94 block: drop bs->job
Drop remaining users of bs->job:
1. assertions actually duplicated by assert(!bs->refcnt)
2. trace-point seems not enough reason to change stream_start to return
   BlockJob pointer
3. Restricting creation of two jobs based on same bs is bad idea, as
   3.1 Some jobs creates filters to be their main node, so, this check
   don't actually prevent creating second job on same real node (which
   will create another filter node) (but I hope it is restricted by
   other mechanisms)
   3.2 Even without bs->job we have two systems of permissions:
   op-blockers and BLK_PERM
   3.3 We may want to run several jobs on one node one day

And finally, drop bs->job pointer itself. Hurrah!

We are going to remove bs->job pointer. Drop it's usage in
blk_iostatus_reset.

blk_iostatus_reset() has only two callers:

1. blk_attach_dev(). This doesn't have anything to do with jobs and
    attaching a new guest device won't solve any problem the job
    encountered, so no reason to reset the iostatus for the job.

2. qmp_cont(). This resets the iostatus for everything. We can just
    call block_job_iostatus_reset() for all block jobs instead of going
    through BlockBackend.

subclass. Flags are still in use for the monitor_init() interface.

1d95db745b monitor: Split out monitor/monitor.c
Move the monitor core infrastructure from monitor/misc.c to
monitor/monitor.c. This is code that can be shared for all targets, so
compile it only once.

What remains in monitor/misc.c after this patch is mostly monitor
command implementations (which could move to hmp-cmds.c or qmp-cmds.c
later) and code that requires a system emulator or is even
target-dependent (including HMP command completion code).

The amount of function and particularly extern variables in
monitor_int.h is probably a bit larger than it needs to be, but this way
no non-trivial code modifications are needed. The interfaces between all
monitor parts can be cleaned up later.

b8e31d6ccc monitor: Make MonitorQMP a child class of Monitor
Currently, struct Monitor mixes state that is only relevant for HMP,
state that is only relevant for QMP, and some actually shared state.
In particular, a MonitorQMP field is present in the state of any
monitor, even if it's not a QMP monitor and therefore doesn't use the
state.

As a first step towards a clean separation between QMP and HMP, let
MonitorQMP extend Monitor and create a MonitorQMP object only when the
monitor is actually a QMP monitor.

Some places accessed Monitor.qmp unconditionally, even for HMP monitors.
They can't keep doing this now, so during the conversion, they are
either changed to become conditional on monitor_is_qmp() or to assert()
that they always get a QMP monitor.

b6c7c2e4a3 monitor: Split monitor_init in HMP and QMP function
Instead of mixing HMP and QMP monitors in the same function, separate
the monitor creation function for both.

While in theory, one could pass both MONITOR_USE_CONTROL and
MONITOR_USE_READLINE before this patch and both flags would do
something, readline support is tightly coupled with HMP: QMP never feeds
its input to readline, and the tab completion function treats the input
as an HMP command. Therefore, this configuration is useless.

After this patch, the QMP path asserts that MONITOR_USE_READLINE is not
set. The HMP path can be used with or without MONITOR_USE_READLINE, like
before.

9b4cc0c2d4 docs/specs/index.rst: Fix minor syntax issues
The docs/specs/index.rst has a couple of minor issues which
we didn't notice because we weren't building the manual:
 * the ToC entry for the new PPC XIVE docs points to
   a nonexistent file
 * the initial comment needs to be marked by '..', not '.',
   or it will appear in the output
 * the title doesn't match the capitialization used by
   the existing interop or devel manuals, and uses
   'full-system emulation' rather than the 'system emulation'
   that the interop manual title uses

Fix these minor issues before we start trying to build the manual.

282d36b5e2 qemu-tech.texi: Remove "QEMU compared to other emulators" section
The "QEMU compared to other emulators" section of our documentation
hasn't been updated since 2015 (and parts of the text are even older).
We're clearly not very well placed to track the evolution of a
dozen other emulation projects, and an inaccurate or out of date
comparison doesn't serve anybody, so we're best off just removing
the whole documentation section.

If anybody cares strongly about maintaining a comparison page,
it's probably better to do that on the project's wiki where
we can update it more dynamically.

1120827fa1 target/arm: Only implement doubles if the FPU supports them
The architecture permits FPUs which have only single-precision
support, not double-precision; Cortex-M4 and Cortex-M33 are
both like that. Add the necessary checks on the MVFR0 FPDP
field so that we UNDEF any double-precision instructions on
CPUs like this.

Note that even if FPDP==0 the insns like VMOV-to/from-gpreg,
VLDM/VSTM, VLDR/VSTR which take double precision registers
still exist.

83655223ac target/arm: Fix typos in trans function prototypes
In several places cut and paste errors meant we were using the wrong
type for the 'arg' struct in trans_ functions called by the
decodetree decoder, because we were using the _sp version of the
struct in the _dp function.  These were harmless, because the two
structs were identical and so decodetree made them typedefs of the
same underlying structure (and we'd have had a compile error if they
were not harmless), but we should clean them up anyway.

fd8a68cdcf target/arm: Stop using cpu_F0s for NEON_2RM_VABS_F
Where Neon instructions are floating point operations, we
mostly use the old VFP utility functions like gen_vfp_abs()
which work on the TCG globals cpu_F0s and cpu_F1s. The
Neon for-each-element loop conditionally loads the inputs
into either a plain old TCG temporary for most operations
or into cpu_F0s for float operations, and similarly stores
back either cpu_F0s or the temporary.

Switch NEON_2RM_VABS_F away from using cpu_F0s, and
update neon_2rm_is_float_op() accordingly.

a90a862b9e hw/arm: Correctly disable FPU/DSP for some ARMSSE-based boards
The SSE-200 hardware has configurable integration settings which
determine whether its two CPUs have the FPU and DSP:
 * CPU0_FPU (default 0)
 * CPU0_DSP (default 0)
 * CPU1_FPU (default 1)
 * CPU1_DSP (default 1)

Similarly, the IoTKit has settings for its single CPU:
 * CPU0_FPU (default 1)
 * CPU0_DSP (default 1)

Of our four boards that use either the IoTKit or the SSE-200:
 * mps2-an505, mps2-an521 and musca-a use the default settings
 * musca-b1 enables FPU and DSP on both CPUs

Currently QEMU models all these boards using CPUs with
both FPU and DSP enabled. This means that we are incorrect
for mps2-an521 and musca-a, which should not have FPU or DSP
on CPU0.

Create QOM properties on the ARMSSE devices corresponding to the
default h/w integration settings, and make the Musca-B1 board
enable FPU and DSP on both CPUs. This fixes the mps2-an521
and musca-a behaviour, and leaves the musca-b1 and mps2-an505
behaviour unchanged.
