| | | | | | | | | | | | | | | | | | | Switch to adding compat properties incrementaly instead of completly overwriting compat_props per machine type. That removes data duplication which we have due to nested [PC|SPAPR]_COMPAT_* macros. It also allows to set default device properties from default foo_machine_options() hook, which will be used in following patch for putting VMGENID device as a function if ISA bridge on pc/q35 machines.

| | | | | | | | | | | | | | | | | | Instead of reusing DT_SDL for Cocoa, use DT_COCOA to indicate that a Cocoa display was requested. configure already ensures CONFIG_COCOA and CONFIG_SDL are never set at the same time. The only case where DT_SDL is used outside a #ifdef CONFIG_SDL block is in the no_frame/alt_grab/ctrl_grab check. That means the only user-visible change is that we will start printing a warning if the SDL-specific options are used in Cocoa mode. This is a bugfix, because no_frame/alt_grab/ctrl_grab are not used by Cocoa code.

* qom: -object error messages lost location, restore itMarkus Armbruster2016-04-281-4/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qemu_opts_foreach() runs its callback with the error location set to the option's location. Any errors the callback reports use the option's location automatically. Commit 90998d5 moved the actual error reporting from "inside" qemu_opts_foreach() to after it. Here's a typical hunk: if (qemu_opts_foreach(qemu_find_opts("object"), - object_create, - object_create_initial, NULL)) { + user_creatable_add_opts_foreach, + object_create_initial, &err)) { + error_report_err(err); exit(1); } Before, object_create() reports from within qemu_opts_foreach(), using the option's location. Afterwards, we do it after qemu_opts_foreach(), using whatever location happens to be current there. Commonly a "none" location. This is because Error objects don't have location information. Problematic. Reproducer: $ qemu-system-x86_64 -nodefaults -display none -object secret,id=foo,foo=bar qemu-system-x86_64: Property '.foo' not found Note no location. This commit restores it: qemu-system-x86_64: -object secret,id=foo,foo=bar: Property '.foo' not found Note that the qemu_opts_foreach() bug just fixed could mask the bug here: if the location it leaves dangling hasn't been clobbered, yet, it's the correct one.

This was a fairly complex change, this will preserve the order of fw_cfg for older versions no matter what order the firmware files actually come in. A list is kept of the correct legacy order and the entries will be inserted based upon their order in the list. Except that some entries are ordered (in a specific area of the list) based upon what order they appear on the command line. Special handling is added for those entries.

* vl: Move cpu_synchronize_all_states() into qemu_system_reset()David Gibson2016-04-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | There are currently 3 calls to qemu_system_reset() in vl.c. Two of them are immediately preceded by a cpu_synchronize_all_states9) and the remaining one should be. The one which doesn't is the very first reset called directly from main(). Without a cpu_synchronize_all_states(), kvm_vcpu_dirty is false at this point from the earlier cpu_synchronize_all_post_init(). That's incorrect because the reset path is quite likely to update the CPU state, and that updated state should be pushed back to KVM, not overwritten with stale data pushed to KVM immediately after init. This patch moves the call to cpu_synchronize_all_states() into qemu_system_reset() for safety, so it is always called. AFAICT this should be safe for the handful of callers outside vl.c - these all appear to be in places where the cpu state is already synchronized so the extra call will be a no-op.

* input: linux evdev supportGerd Hoffmann2016-03-081-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for reading input events directly from linux evdev devices and forward them to the guest. Unlike virtio-input-host which simply passes on all events to the guest without looking at them this will interpret the events and feed them into the qemu input subsystem. Therefore this is limited to what the qemu input subsystem and the emulated input devices are able to handle. Also there is no support for absolute coordinates (tablet/touchscreen). So we are talking here about basic mouse and keyboard support. The advantage is that it'll work without virtio-input drivers in the guest, the events are delivered to the usual ps/2 or usb input devices (depending on what the machine happens to have). And for keyboards qemu is able to switch the keyboard between guest and host on hotkey. The hotkey is hard-coded for now (both control keys), initialy the guest owns the keyboard. Probably most useful when assigning vga devices with vfio and using a physical monitor instead of vnc/spice/gtk as guest display. Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command line. Note that udev has rules which populate /dev/input/by-{id,path} with static names, which might be more convinient to use.

* qom: add helpers for UserCreatable object typesDaniel P. Berrange2016-02-161-62/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QMP monitor code has two helper methods object_add and qmp_object_del that are called from several places in the code (QMP, HMP and main emulator startup). The HMP and main emulator startup code also share further logic that extracts the qom-type & id values from a qdict. We soon need to use this logic from qemu-img, qemu-io and qemu-nbd too, but don't want those to depend on the monitor, nor do we want to duplicate the code. To avoid this, move some code out of qmp.c and hmp.c adding new methods to qom/object_interfaces.c - user_creatable_add - takes a QDict holding a full object definition & instantiates it - user_creatable_add_type - takes an ID, type name, and QDict holding object properties & instantiates it - user_creatable_add_opts - takes a QemuOpts holding a full object definition & instantiates it - user_creatable_add_opts_foreach - variant on user_creatable_add_opts which can be directly used in conjunction with qemu_opts_foreach. - user_creatable_del - takes an ID and deletes the corresponding object The existing code is updated to use these new methods.

* | qapi: Drop unused 'kind' for struct/enum visitEric Blake2016-02-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | visit_start_struct() and visit_type_enum() had a 'kind' argument that was usually set to either the stringized version of the corresponding qapi type name, or to NULL (although some clients didn't even get that right). But nothing ever used the argument. It's even hard to argue that it would be useful in a debugger, as a stack backtrace also tells which type is being visited. Therefore, drop the 'kind' argument as dead.

* | qapi: Swap visit_* arguments for consistent 'name' placementEric Blake2016-02-081-2/+2

This can be a bit confusing to have to mentally swap the parameter order to match JSON order. It's particularly bad for visit_start_struct(), where the 'name' parameter is smack in the middle of the otherwise-related group of 'obj, kind, size' parameters! It's time to do a global swap of the parameter ordering, so that the 'name' parameter is always immediately after the Visitor argument. Additional reason in favor of the swap: the existing include/qjson.h prefers listing 'name' first in json_prop_*(), and I have plans to unify that file with the qapi visitors; listing 'name' first in qapi will minimize churn to the (admittedly few) qjson.h clients. Later patches will then fix docs, object.h, visitor-impl.h, and those clients to match. Done by first patching scripts/qapi*.py by hand to make generated files do what I want, then by running the following Coccinelle script to affect the rest of the code base: $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'` I then had to apply some touchups (Coccinelle insisted on TAB indentation in visitor.h, and botched the signature of visit_type_enum() by rewriting 'const char *const strings[]' to the syntactically invalid 'const char*const[] strings'). The movement of parameters is sufficient to provoke compiler errors if any callers were missed. // Part 1: Swap declaration order @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_start_struct -(TV v, TObj OBJ, T1 ARG1, const char *name, T2 ARG2, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type bool, TV, T1; identifier ARG1; @@ bool visit_optional -(TV v, T1 ARG1, const char *name) +(TV v, const char *name, T1 ARG1) { ... } @@ type TV, TErr, TObj, T1; identifier OBJ, ARG1; @@ void visit_get_next_type -(TV v, TObj OBJ, T1 ARG1, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, TErr errp) { ... } @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_type_enum -(TV v, TObj OBJ, T1 ARG1, T2 ARG2, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type TV, TErr, TObj; identifier OBJ; identifier VISIT_TYPE =~ "^visit_type_"; @@ void VISIT_TYPE -(TV v, TObj OBJ, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, TErr errp) { ... } // Part 2: swap caller order @@ expression V, NAME, OBJ, ARG1, ARG2, ERR; identifier VISIT_TYPE =~ "^visit_type_"; @@ ( -visit_start_struct(V, OBJ, ARG1, NAME, ARG2, ERR) +visit_start_struct(V, NAME, OBJ, ARG1, ARG2, ERR) | -visit_optional(V, ARG1, NAME) +visit_optional(V, NAME, ARG1) | -visit_get_next_type(V, OBJ, ARG1, NAME, ERR) +visit_get_next_type(V, NAME, OBJ, ARG1, ERR) | -visit_type_enum(V, OBJ, ARG1, ARG2, NAME, ERR) +visit_type_enum(V, NAME, OBJ, ARG1, ARG2, ERR) | -VISIT_TYPE(V, OBJ, NAME, ERR) +VISIT_TYPE(V, NAME, OBJ, ERR) ) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-19-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
* | vl: Ensure qapi visitor properly ends struct visitEric Blake2016-02-081-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Guarantee that visit_end_struct() is called if visit_start_struct() succeeded. This matches the behavior of most other uses of visitors, and is a step towards the possibility of a future patch that adds and enforces some tighter semantics to the visitor interface (namely, cleanup of the visitor would no longer have to mop up as many leftovers from an aborted partial visit). The change to code here matches the flow of hmp.c:hmp_object_add(); a later patch will then further simplify the cleanup logic of both places by refactoring visit_end_struct() to not require a second local error object.

* | hmp: Drop pointless allocation during qapi visitEric Blake2016-02-081-3/+1Star
|/ | | | | | | | | | | | | | The qapi visitor contract allows us to visit a virtual structure, where we don't have any corresponding qapi struct. Most such uses pass NULL for @obj; but these two callers were passing a dummy pointer, which then gets allocated to heap memory but then immediately freed without use. Clean this up to suppress unwanted allocation, like we do elsewhere.
