2014-09-29console: add graphic_console_set_hwopsGerd Hoffmann1-2/+9
Add a function to allow display emulations to switch the hwops function pointers. This is useful for devices which have two completely different operation modes. Typical case is the vga compatibility mode vs. native mode in qxl and the upcoming virtio-vga device. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-16qemu-char: Rename register_char_driver_qapi() to register_char_driver()Peter Maydell1-2/+1
Now we have removed the legacy register_char_driver() we can rename register_char_driver_qapi() to the more obvious and shorter name. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1409653457-27863-6-git-send-email-peter.maydell@linaro.org
2014-09-05console: Remove unused QEMU_BIG_ENDIAN_FLAGBenjamin Herrenschmidt1-7/+0
If we need to, we should use the pixman formats instead but for now this is unused except in commented out code so take it out to avoid further confusion about surface endianness. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-05console: add dpy_gfx_update_dirtyGerd Hoffmann1-0/+61
Calls dpy_gfx_update for all dirty scanlines. Works for DisplaySurfaces backed by guest memory (i.e. the ones created using qemu_create_displaysurface_guestmem). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-05console: add qemu_create_displaysurface_guestmemGerd Hoffmann1-0/+37
This patch adds a qemu_create_displaysurface_guestmem helper function. Works simliar to qemu_create_displaysurface_from, but accepts a guest address instead of a host pointer and it handles cpu_physical_memory_{map,unmap} for you. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-05console: stop using PixelFormatGerd Hoffmann1-23/+10
With this patch the qemu console core stops using PixelFormat and pixman format codes side-by-side, pixman format code is the primary way to specify the DisplaySurface format: * DisplaySurface stops carrying a PixelFormat field. * qemu_create_displaysurface_from() expects a pixman format now. Functions to convert PixelFormat to pixman_format_code_t (and back) exist for those who still use PixelFormat. As PixelFormat allows easy access to masks and shifts it will probably continue to exist. [ xenfb added by Benjamin Herrenschmidt ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-05console: reimplement qemu_default_pixelformatGerd Hoffmann1-113/+4

2014-05-26console: rework text terminal cursor logicGerd Hoffmann1-18/+32
Have a global timer. Update all visible terminal windows syncronously. Right now this can be the active_console only, but that will change soon. The global timer will disable itself if not needed, so we only have to care start it if needed. Which might be at console switch time or when a new displaychangelistener is registered.

2014-05-26console: update text terminal surface unconditionallyGerd Hoffmann1-71/+56
These days each QemuConsole has its own private DisplaySurface, so we can simply render updates all the time. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-05-26console: nicer initial screenGerd Hoffmann1-8/+11
Now that we have a function to create a fancy DisplaySurface with a message for the user, to handle non-existing graphics hardware, we can make it more generic and use it for other things too. This patch adds a text line to the in initial DisplaySurface, notifying the user that the display isn't initialized yet by the guest. You can see this in action when starting qemu with '-S'. Also when booting ovmf in qemu (which needs a few moments to initialize itself before it initializes the vga). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-05-26console: Abort on property access errorsKirill Batuzov1-17/+13
All defined properties of QemuConsole are mandatory and no access to them should fail. Nevertheless not checking returned errors is bad because in case of unexpected failure it will hide the bug and cause a memory leak. Abort in case of unexpected property access errors. This change exposed a bug where an attempt was made to write to a read-only property "head". Set "head" property's value at creation time and do not attempt to change it later. This fixes the bug mentioned above. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi1-0/+1
There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi1-1/+3
Some object_property_add_link() callers expect property deletion to unref the link property object. Other callers expect to manage the refcount themselves. The former are currently broken and therefore leak the link property object. This patch adds a flags argument to object_property_add_link() so the caller can specify which refcount behavior they require. The new OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be unreferenced when the property is deleted. This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c, s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c. Rationale for refcount behavior: * hw/core/qdev.c - bus children are explicitly unreferenced, don't interfere - parent_bus is essentially a read-only property that doesn't hold a refcount, don't unref - hotplug_handler is leaked, do unref * hw/dma/xilinx_axidma.c - rx stream "dma" links are set using set_link, therefore they need unref - tx streams are set using set_link, therefore they need unref * hw/net/xilinx_axienet.c - same reasoning as hw/dma/xilinx_axidma.c * hw/pcmcia/pxa2xx.c - pxa2xx bypasses set_link and therefore does not use refcounts * hw/s390x/s390-virtio-bus.c * hw/virtio/virtio-pci.c * hw/virtio/virtio-rng.c * ui/console.c - set_link is used and there is no explicit unref, do unref Cc: Peter Crosthwaite <peter.crosthwaite@petalogix.com> Cc: Alexander Graf <agraf@suse.de> Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

2013-06-10qemu-char: don't issue CHR_EVENT_OPEN in a BHMichael Roth1-0/+4
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET, and it was issued as a bottom-half: 86e94dea5b740dad65446c857f6959eae43e0ba6 Which we basically used to print out a greeting/prompt for the monitor. AFAICT the only reason this was ever done in a BH was because in some cases we'd modify the chr_write handler for a new chardev backend *after* the site where we issued the reset (see: 86e94d:qemu_chr_open_stdio()) At some point this event was renamed to CHR_EVENT_OPENED, and we've maintained the use of this BH ever since. However, due to 9f939df955a4152aad69a19a77e0898631bb2c18, we schedule the BH via g_idle_add(), which is causing events to sometimes be delivered after we've already begun processing data from backends, leading to: known bugs: QMP: session negotation resets with OPENED event, in some cases this is causing new sessions to get sporadically reset potential bugs: hw/usb/redirect.c: can_read handler checks for dev->parser != NULL, which may be true if CLOSED BH has not been executed yet. In the past, OPENED quiesced outstanding CLOSED events prior to us reading client data. If it's delayed, our check may allow reads to occur even though we haven't processed the OPENED event yet, and when we do finally get the OPENED event, our state may get reset. qtest.c: can begin session before OPENED event is processed, leading to a spurious reset of the system and irq_levels gdbstub.c: may start a gdb session prior to the machine being paused To fix these, let's just drop the BH. Since the initial reasoning for using it still applies to an extent, work around that by deferring the delivery of CHR_EVENT_OPENED until after the chardevs have been fully initialized, toward the end of qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This defers delivery long enough that we can be assured a CharDriverState is fully initialized before CHR_EVENT_OPENED is sent. Also, rather than requiring each chardev to do an explicit open, do it automatically, and allow the small few who don't desire such behavior to suppress the OPENED-on-init behavior by setting a 'explicit_be_open' flag. We additionally add missing OPENED events for stdio backends on w32, which were previously not being issued, causing us to not recieve the banner and initial prompts for qmp/hmp.

2013-04-16console: simplify screendumpGerd Hoffmann1-19/+53
Screendumps are alot simpler as we can update non-active QemuConsoles now. So we only need to update the QemuConsole we want write out, then dump the DisplaySurface content into a ppm file. Done. No console switching needed. No special support code in the gfx card emulation needed. Zap it all. Also move ppm_save out of the vga code and next to the qmp_screendump function. For now screen dumping is limited to console #0 (like it used to be), even though it is dead simple to extend it to other consoles.
