d0fb9657a3 docs: fix references to docs/devel/tracing.rst
Commit e50caf4a5c ("tracing: convert documentation to rST")
converted docs/devel/tracing.txt to docs/devel/tracing.rst.

We still have several references to the old file, so let's fix them
with the following command:

  sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt)

f9c481247f hw/input/hid: Add support for keys of jp106 keyboard.
Add support for the following keys: KATAKANAHIRAGANA, HENKAN, MUHENKAN,
RO, and YEN.  Before this commit, these keys did not work as expected
when a jp106 keyboard was connected to the guest as a usb-kbd device.

9d74e6c3e7 pckbd: clear outport_present in outer pre_load()
The variable outport_present is a flag to show if the outport
subsection was loaded. Clear the outport_present flag in the
outer pre_load() function. This method is recommended in the QEMU
manual for developers in the chapter "Migration, Subsections".

314f9064b6 pckbd: remove duplicated keyboard and mouse defines
In 2005 the author of commit daa579632d "PS2 mouse and keyboard
separation (Paul Brook)" and 0e43e99c04 "PS2 mouse and keyboard
separation (Paul Brook)" separated the PS/2 controller code and
the PS/2 keyboard and mouse code. It seems he forgot to remove
a few defines. Remove them now.

f6f57a8298 pckbd: correctly disable PS/2 communication
Currently the PS/2 controller command KBD_CCMD_MOUSE_DISABLE
doesn't disable the PS/2 mouse communication at all, and the
PS/2 controller commands KBD_CCMD_KBD_DISABLE and
KBD_CCMD_KBD_ENABLE only disable and enable the keyboard
interrupt, which is very different from what a real PS/2
controller does. A guest may notice the difference.

Mask out pending data on disabled queues to correctly disable
the PS/2 controller communication.

aa67a42f8d pckbd: add controller response queue
Add a separate queue for PS/2 controller responses. The
responses no longer get queued in the keyboard or mouse queues.
The advantage of this can be seen after the next two patches,
where the guest can disable the PS/2 communication with keyboard
and mouse and still talk to the PS/2 controller.

d1e45668d2 pckbd: PS/2 keyboard throttle
Limit the keyboard data rate to the serial link speed. Some old
DOS software relies on being able to read an incoming scan-code
more than once. After reading keyboard data from the i8042
controller, the guest software has 1ms to read the same data
again.

Use -global i8042.kbd-throttle=on to enable this feature.

To see how this patch works, start a FreeDOS 1.2 guest with the
qemu option -global i8042.kbd-throttle=on and open a text file
with the vim 7.3 32 bit for DOS executable. Then use the cursor
keys (not the cursor keys on the numeric keypad) to move through
the text. Without the kbd-throttle option enabled each keystroke
will move the cursor two positions.

ff6e1624b3 pckbd: don't update OBF flags if KBD_STAT_OBF is set
Don't update the OBF flags in the status register and the cor-
responding IRQ lines if KBD_STAT_OBF is set. Otherwise this
may change the PS/2 event type. If the guest ISR was already
scheduled, the changed event type will be rather surprising for
the guest.

This fixes a mouse event stream corruption. To reproduce the
problem start a FreeDOS 1.2 guest with -machine pc,accel=kvm
and -display gtk. The KVM in-kernel irqchip has to be enabled.
Now open a text file with edit.exe in the guest and hold down
the cursor right key and at the same time move the mouse around.
You will quickly notice erratic mouse movements and unexpected
mouse clicks.

A trace file shows the mouse event stream corruption. Guest
rip 0xce93 (f000:ce93) is the in al,0x60 instruction in the
seabios mouse ISR, guest rip 0xceca (f000:ceca) is the
in al,0x60 instruction in the seabios keyboard ISR.

cutable in a FreeDOS client started with -display sdl and move the
mouse around for a few seconds. You will quickly see erratic mouse
movements and unexpected mouse clicks. CuteMouse (ctmouse.exe) in
FreeDOS doesn't try to re-sync the mouse stream.

019294db68 hw/input/ps2.c: Remove remnants of printf debug
In commit 5edab03d40 we added tracepoints to the ps2 keyboard
and mouse emulation. However we didn't remove all the debug-by-printf
support. In fact there is only one printf() remaining, and it is
redundant with the trace_ps2_write_mouse() event next to it.
Remove the printf() and the now-unused DEBUG* macros.

db1015e92e Move QOM typedefs and add missing includes

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

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

167f1667b1 adb: fix adb-mouse read length and revert disable-reg3-direct-writes workaround
Commit 84051eb400 "adb: add property to disable direct reg 3 writes" introduced
a workaround for spurious writes to ADB register 3 when MacOS 9 enables
autopoll on the mouse device. Further analysis shows that the problem is that
only a partial request is sent, and since the len parameter is ignored then
stale data from the previous request is used causing the incorrect address
assignment.

Remove the disable-reg3-direct-writes workaround and instead check the length
parameter when the write is attempted, discarding the invalid request.
