2017-01-27chardev: qom-ifyMarc-André Lureau
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

2017-01-10curses: Fix compiler warnings (Mingw-w64 redefinition of macro KEY_EVENT)Stefan Weil
For builds with Mingw-w64 as it is included in Cygwin, there are two header files which define KEY_EVENT with different values. This results in lots of compiler warnings like this one: CC vl.o In file included from /qemu/include/ui/console.h:340:0, from /qemu/vl.c:76: /usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined #define KEY_EVENT 0633 /* We were interrupted by an event */ In file included from /usr/share/mingw-w64/include/windows.h:74:0, from /usr/share/mingw-w64/include/winsock2.h:23, from /qemu/include/sysemu/os-win32.h:29, from /qemu/include/qemu/osdep.h:100, from /qemu/vl.c:24: /usr/share/mingw-w64/include/wincon.h:101:0: note: this is the location of the previous definition #define KEY_EVENT 0x1 QEMU only uses the KEY_EVENT macro from wincon.h. Therefore we can undefine the macro coming from curses.h. The explicit include statement for curses.h in ui/curses.c is not needed and was removed. Those two modifications fix the redefinition warnings.

2016-04-11ui/virtio-gpu: add and use qemu_create_displaysurface_pixmanGerd Hoffmann
Add a the new qemu_create_displaysurface_pixman function, to create a DisplaySurface backed by an existing pixman image. In that case there is no need to create a new pixman image pointing to the same backing storage. We can just use the existing image directly. This does not only simplify things a bit, but most importantly it gets the reference counting right, so the backing storage for the pixman image wouldn't be released underneath us. Use new function in virtio-gpu, where using it actually fixes use-after-free crashes.

2016-01-08ui/curses: Fix color attribute of monitor for cursesOGAWA Hirofumi
Current text_console_update() writes totally broken color attributes to console_write_ch(). The format now is writing, [WRONG] bold << 21 | fg << 12 | bg << 8 | char fg == 3bits curses color number bg == 3bits curses color number I can't see this format is where come from. Anyway, this doesn't work at all. What curses expects is actually (and vga.c is using), [RIGHT] bold << 21 | bg << 11 | fg << 8 | char fg == 3bits vga color number bg == 3bits vga color number And curses set COLOR_PAIR() up to match this format, and curses's chtype. I.e, bold | color_pair | char color_pair == (bg << 3 | fg) To fix, this simply uses VGA color number everywhere except curses.c internal. Then, convert it to above [RIGHT] format to write by console_write_ch(). And as bonus, this reduces to expose curses define to other parts (removes COLOR_* from console.c).

2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().

Because it computes the memory region on the fly for every update (with memory_region_find), it cannot enable/disable logging by itself.
