The Chardev events are listed in the QEMUChrEvent enum.
By using the enum in the IOEventHandler typedef we:
- make the IOEventHandler type more explicit (this handler
process out-of-band information, while the IOReadHandler
is in-band),
- help static code analyzers.
This patch was produced with the following spatch script:
@match@
expression backend, opaque, context, set_open;
identifier fd_can_read, fd_read, fd_event, be_change;
@@
qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event,
be_change, opaque, context, set_open);
@depends on match@
identifier opaque, event;
identifier match.fd_event;
@@
static
-void fd_event(void *opaque, int event)
+void fd_event(void *opaque, QEMUChrEvent event)
{
...
}
Then the typedef was modified manually in
include/chardev/char-fe.h.

With stereo playback, they need about 375 minutes of continuous audio
playback to overflow, which is usually not a problem (as stopping and
later resuming playback resets the counters). But with 7.1 audio, they
only need about 95 minutes to overflow.
After the overflow, the buf->prod % USBAUDIO_PACKET_SIZE(channels)
assertion no longer holds true, which will result in overflowing the
buffer. With 64 bit variables, it would take about 762000 years to
overflow.

sysemu/sysemu.h is a rather unfocused dumping ground for stuff related

objects (not counting tests and objects that don't depend on
qemu/osdep.h, down from 5400 due to the previous two commits).
* It pulls in more than a dozen additional headers.

Almost a third of its inclusions are actually superfluous. Delete

from char/serial.h to char/serial.c.
hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it. The compiler is cool with that, but include it anyway.

In my "build everything" tree, changing migration/qemu-file-types.h
triggers a recompile of some 2600 out of 6600 objects (not counting
tests and objects that don't depend on qemu/osdep.h).
The culprit is again hw/hw.h, which supposedly includes it for
convenience.
Include migration/qemu-file-types.h only where it's needed. Touching
it now recompiles less than 200 objects.

The USB_EHCI entry currently include PCI code. Since the EHCI
implementation is already split in sysbus/PCI, add a new
USB_EHCI_PCI. There are no logical changes, but the Kconfig

A Xen public header have been imported into QEMU (by
f65eadb639 "xen: import ring.h from xen"), but there are other header
that depends on ring.h which come from the system when building QEMU.
This patch resolves the issue of having headers from the system
importing a different copie of ring.h.
This patch is prompt by the build issue described in the previous
patch: 'Revert xen/io/ring.h of "Clean up a few header guard symbols"'
ring.h and the new imported headers are moved to
"include/hw/xen/interface" as those describe interfaces with a guest.
The imported headers are cleaned up a bit while importing them: some
part of the file that QEMU doesn't use are removed (description
of how to make hypercall in grant_table.h have been removed).
Other cleanup:
- xen-mapcache.c and xen-legacy-backend.c don't need grant_table.h.
- xenfb.c doesn't need event_channel.h.

Seems some devices become confused when we call
libusb_set_configuration(). So before calling the function check
whenever the device has multiple configurations in the first place, and
in case it hasn't (which is the case for the majority of devices) simply
skip the call as it will have no effect anyway.

Some machines (like the pxa2xx-based ARM machines) only have a sysbus
OHCI controller, but no PCI. With the new Kconfig-style build system,
it will soon be possible to create QEMU binaries that only contain
such PCI-less machines. However, the two OHCI controllers, for sysbus
and for PCI, are currently both located in one file, so the PCI code
is still required for linking here. Move the OHCI-PCI device code
into a separate file, so that it is possible to use the sysbus OHCI
device also without the PCI dependency.

The ohci_die() function always assumes to be running with a PCI OHCI
controller and calls the PCI-specific functions pci_set_word(). However,
this function might also get called for the sysbus OHCI devices, so it
likely fails in that case. To fix this issue, change the code now, so that
there are two implementations now, one for sysbus and one for PCI, and
use the right function via a function pointer in the OHCIState structure.
