e016a844dd hw/display/cirrus_vga: Fix hexadecimal format string specifier
The '%u' conversion specifier is for decimal notation.
When prefixing a format with '0x', we want the hexadecimal
specifier ('%x').

ae5643ecc6 hw/display/tcx: Allow 64-bit accesses to framebuffer stippler and blitter
The S24/TCX datasheet is listed as "Unable to locate" on [1].

However the NetBSD revision 1.32 of the driver introduced
64-bit accesses to the stippler and blitter [2]. It is safe
to assume these memory regions are 64-bit accessible.
QEMU implementation is 32-bit, so fill the 'impl' fields.

Michael Lorenz (author of the NetBSD code [2]) provided us with more
information in [3]:

> IIRC the real hardware *requires* 64bit accesses for stipple and
> blitter operations to work. For stipples you write a 64bit word into
> STIP space, the address defines where in the framebuffer you want to
> draw, the data contain a 32bit bitmask, foreground colour and a ROP.
> BLIT space works similarly, the 64bit word contains an offset were to
> read pixels from, and how many you want to copy.
>
> One more thing since there seems to be some confusion - 64bit accesses
> on the framebuffer are fine as well. TCX/S24 is *not* an SBus device,
> even though its node says it is.
> S24 is a card that plugs into a special slot on the SS5 mainboard,
> which is shared with an SBus slot and looks a lot like a horizontal
> UPA slot. Both S24 and TCX are accessed through the Micro/TurboSPARC's
> AFX bus which is 64bit wide and intended for graphics.
> Early FFB docs even mentioned connecting to both AFX and UPA,
> no idea if that was ever realized in hardware though.

d73415a315 qemu/atomic.h: rename atomic_ to qatomic_
clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:

  $ CC=clang CXX=clang++ ./configure ... && make
  ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)

Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.

This patch was generated using:

  $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \
    sort -u >/tmp/changed_identifiers
  $ for identifier in $(</tmp/changed_identifiers); do
        sed -i "s%\<$identifier\>%q$identifier%g" \
            $(git grep -I -l "\<$identifier\>")
    done

I manually fixed line-wrap issues and misaligned rST tables.

b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

c7050f3f16 hw/display/artist: Refactor x/y coordination extraction
Simplify the code by using new introduced ADDR_TO_Y() and ADDR_TO_X()
macros. Those macros extract the x/y-coordinate from the given uint32.

As further simplification the extraction of the x/y coordinates for
VRAM_WRITE_INCR_Y and VRAM_WRITE_INCR_X can be done centrally in
vram_bit_write(), so move this code up into the function.

ADDR_TO_Y() is still limited to 10 bits which allow to address up to of
1024 lines - this will be increased in a follow-up patch.
