2016-07-12input: add trace events for full queuesGerd Hoffmann3-2/+10
It isn't unusual to happen, for example during reboot when the guest doesn't reveice events for a while. So better don't flood stderr with alarming messages. Turn them into tracepoints instead so they can be enabled in case they are needed for trouble-shooting.

2016-06-29pckbd: handle A20 IRQ as GPIOEfimov Vasily1-14/+7
The i8042 device has outgouing IRQ line A20. Currently the IRQ is referenced by a pointer which normally is set during machine initialization. The pointer is never changed at runtime. So common GPIO model can be applied to A20 IRQ line. Note that checking for IRQ to be connected as in previous version of code is not required because qemu_set_irq will do it.

virtio-input is simple enough that it doesn't need to xfer any state. Still we have to wire up savevm manually, so the generic pci and virtio are saved correctly. Additionally we need to do some post-load processing to figure whenever the guest uses the device or not, so we can give input routing hints to the qemu input layer using qemu_input_handler_{activate,deactivate}.

This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster3-0/+3
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

2016-03-18qapi: Don't special-case simple union wrappersEric Blake3-11/+11
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>
2016-03-05ui: Shorten references into InputEventEric Blake3-39/+57
An upcoming patch will alter how simple unions, like InputEvent, are laid out, which will impact all lines of the form 'evt->u.XXX' (expanding it to the longer 'evt->u.XXX.data'). For better legibility in that patch, and less need for line wrapping, it's better to use a temporary variable to reduce the effect of a layout change to just the variable initializations, rather than every reference within an InputEvent. There was one instance in hid.c:hid_pointer_event() where the code was referring to evt->u.rel inside the case label where evt->u.abs is the correct name; thankfully, both members of the union have the same type, so it happened to work, but it is now cleaner.

2016-02-06virtio: move allocation to virtqueue_pop/vring_popPaolo Bonzini1-8/+16
The return code of virtqueue_pop/vring_pop is unused except to check for errors or 0. We can thus easily move allocation inside the functions and just return a pointer to the VirtQueueElement. The advantage is that we will be able to allocate only the space that is needed for the actual size of the s/g list instead of the full VIRTQUEUE_MAX_SIZE items. Currently VirtQueueElement takes about 48K of memory, and this kind of allocation puts a lot of stress on malloc. By cutting the size by two or three orders of magnitude, malloc can use much more efficient algorithms. The patch is pretty large, but changes to each device are testable more or less independently. Splitting it would mostly add churn. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.

2015-12-17qapi: Change munging of CamelCase enum valuesEric Blake3-6/+6
When munging enum values, the fact that we were passing the entire prefix + value through camel_to_upper() meant that enum values spelled with CamelCase could be turned into CAMEL_CASE. However, this provides a potential collision (both OneTwo and One-Two would munge into ONE_TWO) for enum types, when the same two names are valid side-by-side as QAPI member names. By changing the generation of enum constants to always be prefix + '_' + c_name(value, False).upper(), and ensuring that there are no case collisions (in the next patches), we no longer have to worry about names that would be distinct as QAPI members but collide as variant tag names, without having to think about what munging the heuristics in camel_to_upper() will actually perform on an enum value. Making the change will affect enums that did not follow coding conventions, using 'CamelCase' rather than desired 'lower-case'. Thankfully, there are only two culprits: InputButton and ErrorClass. We already tweaked ErrorClass to make it an alias of QapiErrorClass, where only the alias needs changing rather than the whole tree. So the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN). That part of this commit may later need reverting if we rename the enum constants from 'WheelUp' to 'wheel-up' as part of moving x-input-send-event to a stable interface; but at least we have documentation bread crumbs in place to remind us (commit 513e7cd), and it matches the fact that SDL constants are also spelled SDL_BUTTON_WHEELUP.

We have two issues with our qapi union layout: 1) Even though the QMP wire format spells the tag 'type', the C code spells it 'kind', requiring some hacks in the generator. 2) The C struct uses an anonymous union, which places all tag values in the same namespace as all non-variant members. This leads to spurious collisions if a tag value matches a non-variant member's name. Make the conversion to the new layout for input-related code.

Symptom: $ qemu-system-x86_64 -m 10000000 Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456: upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory Aborted (core dumped) Root cause: commit ef701d7 screwed up handling of out-of-memory conditions. Before the commit, we report the error and exit(1), in one place, ram_block_add(). The commit lifts the error handling up the call chain some, to three places. Fine. Except it uses &error_abort in these places, changing the behavior from exit(1) to abort(), and thus undoing the work of commit 3922825 "exec: Don't abort when we can't allocate guest memory". The three places are: * memory_region_init_ram() Commit 4994653 (right after commit ef701d7) lifted the error handling further, through memory_region_init_ram(), multiplying the incorrect use of &error_abort. Later on, imitation of existing (bad) code may have created more. * memory_region_init_ram_ptr() The &error_abort is still there. * memory_region_init_rom_device() Doesn't need fixing, because commit 33e0eb5 (soon after commit ef701d7) lifted the error handling further, and in the process changed it from &error_abort to passing it up the call chain. Correct, because the callers are realize() methods. Fix the error handling after memory_region_init_ram() with a Coccinelle semantic patch: @r@ expression mr, owner, name, size, err; position p; @@ memory_region_init_ram(mr, owner, name, size, ( - &error_abort + &error_fatal | err@p ) ); @script:python@ p << r.p; @@ print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column) When the last argument is &error_abort, it gets replaced by &error_fatal. This is the fix. If the last argument is anything else, its position is reported. This lets us check the fix is complete. Four positions get reported: * ram_backend_memory_alloc() Error is passed up the call chain, ultimately through user_creatable_complete(). As far as I can tell, it's callers all handle the error sanely. * fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize() DeviceClass.realize() methods, errors handled sanely further up the call chain. We're good. Test case again behaves: $ qemu-system-x86_64 -m 10000000 qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory [Exit 1 ] The next commits will repair the rest of commit ef701d7's damage.

2015-07-17hid: clarify hid_keyboard_process_keycodePaolo Bonzini1-4/+28
Coverity thinks the fallthroughs are smelly. They are correct, but everything else in this function is like "wut?". Refer explicitly to bits 8 and 9 of hs->kbd.modifiers instead of shifting right first and using (1 << 7). Document what the scancode is when hid_code is 0xe0. And add plenty of comments.

2015-06-23virtio-input: evdev passthroughGerd Hoffmann2-0/+189
This allows to assign host input devices to the guest: qemu -device virtio-input-host-pci,evdev=/dev/input/event<nr> The guest gets exclusive access to the input device, so be careful with assigning the keyboard if you have only one connected to your machine.

2015-06-23virtio-input: move properties, use virtio_instance_init_commonGerd Hoffmann1-1/+7
Move properties from virtio-*-pci to virtio-*-device. Also make better use of QOM and attach common properties to the abstract parent classes (virtio-input-device and virtio-input-pci-device). Switch the hid device instance init functions over to use virtio_instance_init_common, so we get the properties of the virtio device aliased properly to the virtio pci proxy.

2015-06-12migration: Use normal VMStateDescriptions for SubsectionsJuan Quintela2-19/+14
We create optional sections with this patch. But we already have optional subsections. Instead of having two mechanism that do the same, we can just generalize it. For subsections we just change: - Add a needed function to VMStateDescription - Remove VMStateSubsection (after removal of the needed function it is just a VMStateDescription) - Adjust the whole tree, moving the needed function to the corresponding VMStateDescription Signed-off-by: Juan Quintela <quintela@redhat.com>
2015-06-01virtio: make features 64bit wideGerd Hoffmann1-1/+1
Make features 64bit wide everywhere. On migration a full 64bit guest_features field is sent if one of the high bits is set, in addition to the lower 32bit guest_features field which must stay for compatibility reasons. That way we send the lower 32 feature bits twice, but the code is simpler because we don't have to split and compose the 64bit features into two 32bit fields.

2015-05-29virtio-input: emulated devices [device]Gerd Hoffmann2-0/+503
This patch adds the virtio-input-hid base class and virtio-{keyboard,mouse,tablet} subclasses building on the base class. They are hooked up to the qemu input core and deliver input events to the guest like all other hid devices (ps/2 kbd, usb tablet, ...). Using them is as simple as adding "-device virtio-tablet-device" to your command line, for use all transports except pci. virtio-pci support comes as separate patch, once virtio-pci got virtio 1.0 support.

2015-05-29virtio-input: core code & base class [device]Gerd Hoffmann2-0/+286
This patch adds virtio-input support to qemu. It brings a abstract base class providing core support, other classes can build on it to actually implement input devices. virtio-input basically sends linux input layer events (evdev) over virtio. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-03-09adb.c: include ADBDevice parent state in KBDState and MouseStateMark Cave-Ayland1-4/+18
The parent ADBDevice contains the device id on the ADB bus. Make sure that this state is included in both its subclasses since some clients (such as OpenBIOS) reprogram each device id after enumeration.

2015-01-22hw/input/hid.c Fix capslock hid codeDinar Valeev1-1/+1
When ever USB keyboard is used, e.g. '-usbdevice keyboard' pressing caps lock key send 0x32 hid code, which is treated as backslash. Instead it should be 0x39 code. This affects sending uppercase keys, as they typed whith caps lock active. While on x86 this can be workarounded by using ps/2 protocol. On Power it is crusial as we don't have anything else than USB. This is fixes guest automation tasts over vnc.
