2020-01-14display/gtk: get proper refreshrateNikola Pavlica
Because some VMs in QEMU can get GPU virtualization (using technologies such as iGVT-g, as mentioned previously), they could produce a video output that had a higher display refresh rate than of what the GTK display was displaying. (fxp. Playing a video game inside of a Windows VM at 60 Hz, while the output stood locked at 33 Hz because of defaults set in include/ui/console.h) Since QEMU does indeed have internal systems for determining frame times as defined in ui/console.c. The code checks for a variable called update_interval that it later uses for time calculation. This variable, however, isn't defined anywhere in ui/gtk.c and instead ui/console.c just sets it to GUI_REFRESH_INTERVAL_DEFAULT which is 30 update_interval represents the number of milliseconds per display refresh, and by doing some math we get that 1000/30 = 33.33... Hz This creates the mentioned problem and what this patch does is that it checks for the display refresh rate reported by GTK itself (we can take this as a safe value) and just converts it back to a number of milliseconds per display refresh.

2020-01-09semihosting: add qemu_semihosting_console_inc for SYS_READCKeith Packard
Provides a blocking call to read a character from the console using semihosting.chardev, if specified. This takes some careful command line options to use stdio successfully as the serial ports, monitor and semihost all want to use stdio. Here's a sample set of command line options which share stdio between semihost, monitor and serial ports: qemu \ -chardev stdio,mux=on,id=stdio0 \ -serial chardev:stdio0 \ -semihosting-config enable=on,chardev=stdio0 \ -mon chardev=stdio0,mode=readline This creates a chardev hooked to stdio and then connects all of the subsystems to it. A shorter mechanism would be good to hear about.

2020-01-08chardev: use QEMUChrEvent instead of intPaolo Bonzini
This uses the QEMUChrEvent enum everywhere except in IOEventHandler. The IOEventHandler change needs to happen at once for all front ends and is done with Coccinelle in the next patch. (Extracted from a patch by Philippe Mathieu-Daudé). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-01-08ppc/pnv: fix check on return value of blk_getlength()Cédric Le Goater
blk_getlength() returns an int64_t but the result is stored in a uint32_t. Errors (negative values) won't be caught by the check in pnv_pnor_realize() and blk_blockalign() will allocate a very large buffer in such cases. Fixes Coverity issue CID 1412226.

2020-01-08spapr, pnv, xive: Add a "xive-fabric" link to the XIVE routerGreg Kurz
In order to get rid of qdev_get_machine(), first add a pointer to the XIVE fabric under the XIVE router and make it configurable through a QOM link property. Configure it in the spapr and pnv machine. In the case of pnv, the XIVE routers are under the chip, so this is done with a QOM alias property of the POWER9 pnv chip.

2020-01-08mos6522: remove anh registerLaurent Vivier
Register addr 1 is defined as buffer A with handshake (vBufAH), register addr 15 is also defined as buffer A without handshake (vBufA). As both addresses access the same register, remove the definition of 'anh' and use only 'a' (with VIA_REG_ANH and VIA_REG_A).
