2017-01-31char: remove class kind fieldMarc-André Lureau
The class kind is necessary to lookup the chardev name in qmp_chardev_add() after calling qemu_chr_new_from_opts() and to set the appropriate ChardevBackend (mainly to free the right fields). qemu_chr_new_from_opts() can be changed to use a non-qmp function using the chardev class typename. Introduce qemu_chardev_add() to be called from qemu_chr_new_from_opts() and remove the class chardev kind field. Set the backend->type in the parse callback (when non-common fields are added).

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.

2016-10-24char: move front end handlers in CharBackendMarc-André Lureau
Since the hanlders are associated with a CharBackend, rather than the CharDriverState, it is more appropriate to store in CharBackend. This avoids the handler copy dance in qemu_chr_fe_set_handlers() then mux_chr_update_read_handler(), by storing the CharBackend pointer directly. Also a mux CharDriver should go through mux->backends[focused], since chr->be will stay NULL. Before that, it was possible to call chr->handler by mistake with surprising results, for ex through qemu_chr_be_can_write(), which would result in calling the last set handler front end, not the one with focus.

2016-03-18qapi: Don't special-case simple union wrappersEric Blake
Simple unions were carrying a special case that hid their 'data' QMP member from the resulting C struct, via the hack method QAPISchemaObjectTypeVariant.simple_union_type(). But by using the work we started by unboxing flat union and alternate branches, coupled with the ability to visit the members of an implicit type, we can now expose the simple union's implicit type in qapi-types.h: | struct q_obj_ImageInfoSpecificQCow2_wrapper { | ImageInfoSpecificQCow2 *data; | }; | | struct q_obj_ImageInfoSpecificVmdk_wrapper { | ImageInfoSpecificVmdk *data; | }; ... | struct ImageInfoSpecific { | ImageInfoSpecificKind type; | union { /* union tag is @type */ | void *data; |- ImageInfoSpecificQCow2 *qcow2; |- ImageInfoSpecificVmdk *vmdk; |+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2; |+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk; | } u; | }; Doing this removes asymmetry between QAPI's QMP side and its C side (both sides now expose 'data'), and means that the treatment of a simple union as sugar for a flat union is now equivalent in both languages (previously the two approaches used a different layer of dereferencing, where the simple union could be converted to a flat union with equivalent C layout but different {} on the wire, or to an equivalent QMP wire form but with different C representation). Using the implicit type also lets us get rid of the simple_union_type() hack. Of course, now all clients of simple unions have to adjust from using su->u.member to using su->u.member.data; while this touches a number of files in the tree, some earlier cleanup patches helped minimize the change to the initialization of a temporary variable rather than every single member access. The generated qapi-visit.c code is also affected by the layout change: |@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member | } | switch (obj->type) { | case IMAGE_INFO_SPECIFIC_KIND_QCOW2: |- visit_type_ImageInfoSpecificQCow2(v, "data", &obj->u.qcow2, &err); |+ visit_type_q_obj_ImageInfoSpecificQCow2_wrapper_members(v, &obj->u.qcow2, &err); | break; | case IMAGE_INFO_SPECIFIC_KIND_VMDK: |- visit_type_ImageInfoSpecificVmdk(v, "data", &obj->u.vmdk, &err); |+ visit_type_q_obj_ImageInfoSpecificVmdk_wrapper_members(v, &obj->u.vmdk, &err); | break; | default: | abort(); Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <1458254921-17042-13-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

2016-01-15qemu-char: add logfile facility to all chardev backendsDaniel P. Berrange
Typically a UNIX guest OS will log boot messages to a serial port in addition to any graphical console. An admin user may also wish to use the serial port for an interactive console. A virtualization management system may wish to collect system boot messages by logging the serial port, but also wish to allow admins interactive access. Currently providing such a feature forces the mgmt app to either provide 2 separate serial ports, one for logging boot messages and one for interactive console login, or to proxy all output via a separate service that can multiplex the two needs onto one serial port. While both are valid approaches, they each have their own downsides. The former causes confusion and extra setup work for VM admins creating disk images. The latter places an extra burden to re-implement much of the QEMU chardev backends logic in libvirt or even higher level mgmt apps and adds extra hops in the data transfer path. A simpler approach that is satisfactory for many use cases is to allow the QEMU chardev backends to have a "logfile" property associated with them. $QEMU -chardev socket,host=localhost,port=9000,\ server=on,nowait,id-charserial0,\ logfile=/var/log/libvirt/qemu/test-serial0.log -device isa-serial,chardev=charserial0,id=serial0 This patch introduces a 'ChardevCommon' struct which is setup as a base for all the ChardevBackend types. Ideally this would be registered directly as a base against ChardevBackend, rather than each type, but the QAPI generator doesn't allow that since the ChardevBackend is a non-discriminated union. The ChardevCommon struct provides the optional 'logfile' parameter, as well as 'logappend' which controls whether QEMU truncates or appends (default truncate). Signed-off-by: Daniel P.

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).

2015-01-19ui: Add dpy_gfx_check_format() to check backend shared surface supportBenjamin Herrenschmidt
This allows VGA to decide whether to use a shared surface based on whether the UI backend supports the format or not. Backends that don't provide the new callback fallback to native 32 bpp which is equivalent to what was supported before. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> [ kraxel: fix console check, allow only 32 bpp as fallback ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-09-29console: add graphic_console_set_hwopsGerd Hoffmann
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 Maydell
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 Herrenschmidt
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 Hoffmann
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 Hoffmann
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>
