e36a25cb47 arm: Move systick device creation from NVIC to ARMv7M object
There's no particular reason why the NVIC should be owning the
SysTick device objects; move them into the ARMv7M container object
instead, as part of consolidating the "create the devices which are
built into an M-profile CPU and map them into their architected
locations in the address space" work into one place.

This involves temporarily creating a duplicate copy of the
nvic_sysreg_ns_ops struct and its read/write functions (renamed as
v7m_sysreg_ns_*), but we will delete the NVIC's copy of this code in
a subsequent patch.

2f9db77ea8 arm: Move M-profile RAS register block into its own device
Currently we implement the RAS register block within the NVIC device.
It isn't really very tightly coupled with the NVIC proper, so instead
move it out into a sysbus device of its own and have the top level
ARMv7M container create it and map it into memory at the right
address.

ab17a3fe74 ppc/pnv: Use a simple incrementing index for the chip-id

modeled a two socket system with dual chip modules as found on some P8
Tuleta systems (8286-42A). But this is hardly used and not relevant

62fffaa6c9 stubs: Remove unused arch_type.c stub
We added a stub for the arch_type global in commit 5964ed56d9 so
that we could compile blockdev.c into the tools.  However, in commit
9db1d3a2be we removed the only use of arch_type from blockdev.c.
The stub is therefore no longer needed, and we can delete it again,
together with the QEMU_ARCH_NONE value that only the stub was using.

4f9205be45 monitor: Use accel_find("kvm") instead of kvm_available()
The kvm_available() function reports whether KVM support was
compiled into the QEMU binary; it returns the value of the
CONFIG_KVM define.

The only place in the codebase where we use this function is
in qmp_query_kvm(). Now that accelerators are based on QOM
classes we can instead use accel_find("kvm") and remove the
kvm_available() function.

Since commit 9894dc0cdc "char: convert

can actually be a QIOChannel, which is not a GIOChannel (but a QEMU
Object).

Even though we never used that pointer, change the callback type to warn
the users. Possibly a better fix later, we may want to store the
callback and call it from intermediary functions.

14c7e06e72 ppc/vof: Fix Coverity issues
Coverity reported issues which are caused by mixing of signed return codes
from DTC and unsigned return codes of the client interface.

This introduces PROM_ERROR and makes distinction between the error types.

This fixes NEGATIVE_RETURNS, OVERRUN issues reported by Coverity.

This adds a comment about the return parameters number in the VOF hcall.
The reason for such counting is to keep the numbers look the same in
vof_client_handle() and the Linux (an OF client).

vmc->client_architecture_support() returns target_ulong and we want to
propagate this to the client (for example H_MULTI_THREADS_ACTIVE).
The VOF path to do_client_architecture_support() needs chopping off
the top 32bit but SLOF's H_CAS does not; and either way the return values
are either 0 or 32bit negative error code. For now this chops
the top 32bits.

This makes "claim" fail if the allocated address is above 4GB as
the client interface is 32bit. This still allows claiming memory above
4GB as potentially initrd can be put there and the client can read
the address from the FDT's "available" property.

Commit db1ffc32dd ("qemu/bitops.h: add bitrev8 implementation") introduced
a bitrev8() function to reverse the bit ordering required for storing the
MAC address in the q800 PROM.

This function is not required since QEMU implements its own revbit8()
function which does exactly the same thing. Remove the extraneous
bitrev8() function and switch its only caller in hw/m68k/q800.c to
use revbit8() instead.

584af1f1d9 ui/gtk: add a keyboard fifo to the VTE consoles
Since commit 8eb13bbbac ("ui/gtk: vte: fix sending multiple
characeters") it's very easy to lock up QEMU with the GTK ui.
If you configure a guest with a serial device and the guest
doesn't listen on this device, QEMU will lock up after
entering two characters in the serial console. That's because
current code uses a busy loop for the chardev write retries
and the busy loop doesn't terminate in this case.

To fix this problem add a fifo to the VTE consoles and use the
chr_accept_input() callback function to write the remaining
characters in the queue to the chardev.

The fifo has a size of 4096 bytes, so one can copy and paste
a fairly large URL or file path.

f7e68c9c99 tcg/plugins: implement a qemu_plugin_user_exit helper
In user-mode emulation there is a small race between preexit_cleanup
and exit_group() which means we may end up calling instrumented
instructions before the kernel reaps child threads. To solve this we
implement a new helper which ensures the callbacks are flushed along
with any translations before we let the host do it's a thing.

While we are at it make the documentation of
qemu_plugin_register_atexit_cb clearer as to what the user can expect.

18fa3ebc45 qapi: introduce forwarding visitor
This new adaptor visitor takes a single field of the adaptee, and exposes it
with a different name.

This will be used for QOM alias properties.  Alias targets can of course
have a different name than the alias property itself (e.g. a machine's
pflash0 might be an alias of a property named 'drive').  When the target's
getter or setter invokes the visitor, it will use a different name than
what the caller expects, and the visitor will not be able to find it
(or will consume erroneously).

The solution is for alias getters and setters to wrap the incoming
visitor, and forward the sole field that the target is expecting while
renaming it appropriately.

8a13b9bc0f hw/display: fix virgl reset regression
Before commit 49afbca3b0 ("virtio-gpu: drop
use_virgl_renderer"), use_virgl_renderer was preventing calling GL
functions from non-GL context threads. The innocuously looking

  g->parent_obj.use_virgl_renderer = false;

was set the first time virtio_gpu_gl_reset() was called, during
pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset()
calls in IO threads, without associated GL context, were thus skipping
GL calls and avoided warnings or crashes (see also
https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).

84f1561629 accel/tcg: Add CF_NO_GOTO_TB and CF_NO_GOTO_PTR
Move the -d nochain check to bits on tb->cflags.
These will be used for more than -d nochain shortly.

Set bits during curr_cflags, test them in translator_use_goto_tb,
assert we're not doing anything odd in tcg_gen_goto_tb.  The test
in tcg_gen_exit_tb is redundant with the assert for goto_tb_issue_mask.

043e35d98c accel/tcg: Move curr_cflags into cpu-exec.c
We will shortly have more than a simple member read here,
with stuff not necessarily exposed to exec/exec-all.h.

78ff82bb1b accel/tcg: Reduce CF_COUNT_MASK to match TCG_MAX_INSNS
The space reserved for CF_COUNT_MASK was overly large.
Reduce to free up cflags bits and eliminate an extra test.

be9568b4e0 tcg: Rename helper_atomic_*_mmu and provide for user-only
Always provide the atomic interface using TCGMemOpIdx oi
and uintptr_t retaddr.  Rename from helper_* to cpu_* so
as to (mostly) match the exec/cpu_ldst.h functions, and
to emphasize that they are not callable from TCG directly.

9ef0c6d6a7 qemu/atomic: Add aligned_{int64,uint64}_t types
Use it to avoid some clang-12 -Watomic-alignment errors,
forcing some structures to be aligned and as a pointer when
we have ensured that the address is aligned.
