2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster1-1/+1
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().

2015-06-22disas: Remove uses of CPU envPeter Crosthwaite1-1/+1
disas does not need to access the CPU env for any reason. Change the APIs to accept CPU pointers instead. Small change pattern needs to be applied to all target translate.c. This brings us closer to making disas.o a common-obj and less architecture specific in general. Cc: Richard Henderson <rth@twiddle.net> Cc: Peter Maydell <peter.maydell@linaro.org> Cc: "Edgar E.

2015-06-22monitor: Split mon_get_cpu fn to remove ENV_GET_CPUPeter Crosthwaite1-36/+29
The monitor currently has one helper, mon_get_cpu() which will return an env pointer. The target specific users of this API want an env, but all the target agnostic users really just want the cpu pointer. These users then need to use the target-specifically defined ENV_GET_CPU to navigate back up to the CPU from the ENV. Split the API for the two uses cases to remove all need for ENV_GET_CPU.

There's too much going on in monitor_parse_command(). Split up the arguments parsing bits into a separate function monitor_parse_arguments(). Let the original function check for command validity and sub-commands if any and return data (*cmd) that the newly introduced function can process and return a QDict.

2015-06-02monitor: Drop broken, unused asynchronous command interfaceMarkus Armbruster1-68/+2
The asynchronous monitor command interface goes back to commit 940cc30 (Jan 2010). Added a third case to command execution. The hope back then according to the commit message was that all commands get converted to the asynchronous interface, killing off the other two cases. Didn't happen. The initial asynchronous commands balloon and info balloon were converted back to synchronous long ago (commit 96637bc and d72f32), with commit messages calling the asynchronous interface "not fully working" and "deprecated". The only other user went away in commit 3b5704b. New code generally uses synchronous commands and asynchronous events. What exactly is still "not fully working" with asynchronous commands? Well, here's a bug that defeats actual asynchronous use pretty reliably: the reply's ID is wrong (and has always been wrong) unless you use the command synchronously! To reproduce, we need an asynchronous command, so we have to go back before commit 3b5704b. Run QEMU with spice: $ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio {"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} Connect a spice client in another terminal: $ remote-viewer spice://localhost:5900 Set up a migration destination dummy in a third terminal: $ socat TCP-LISTEN:12345 STDIO Now paste the following into the QMP monitor: { "execute": "qmp_capabilities", "id": "i0" } { "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } } { "execute": "query-kvm", "id": "i2" } Produces two replies immediately, one to qmp_capabilities, and one to query-kvm: {"return": {}, "id": "i0"} {"return": {"enabled": false, "present": true}, "id": "i2"} Both are correct. Two lines of debug output from libspice-server not shown. Now EOF socat's standard input to make it close the connection. This makes the asynchronous client_migrate_info complete. It replies: {"return": {}} Bug: "id": "i1" is missing. Two lines of debug output from libspice-server not shown. Cherry on top: storage for the missing ID is leaked. Get rid of this stuff before somebody hurts himself with it.

2015-04-27monitor: check return value of qemu_find_net_clients_except()Jason Wang1-4/+4
qemu_find_net_clients_except() may return a value which is greater than the size of array we provided. So we should check this value before using it, otherwise this may cause unexpected memory access. This patch fixes the net related command completion when we have a virtio-net nic with more than 255 queues.

2015-04-27monitor: Make client_migrate_info synchronousMarkus Armbruster1-3/+2
Live migration with spice works like this today: (1) client_migrate_info monitor cmd (2) spice server notifies client, client connects to target host. (3) qemu waits until spice client connect is finished. (4) send over vmstate (i.e. main part of live migration). (5) spice handover to target host. (3) is implemented by making client_migrate_info a async monitor command. This is the only async monitor command we have. The original reason to implement this dance was that qemu did not accept new tcp connections while the incoming migration was running, so (2) and (4) could not be done in parallel. That issue was fixed long ago though. Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp connects while the incoming migration runs. Time to drop step (3). This patch does exactly that, by making the monitor command synchronous and removing the code needed to handle the async monitor command in ui/spice-core.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-04-26Switch non-CPU callers from ld/st*_phys to address_space_ld/st*Peter Maydell1-1/+2
Switch all the uses of ld/st*_phys to address_space_ld/st*, except for those cases where the address space is the CPU's (ie cs->as). This was done with the following script which generates a Coccinelle patch. A few over-80-columns lines in the result were rewrapped by hand where Coccinelle failed to do the wrapping automatically, as well as one location where it didn't put a line-continuation '\' when wrapping lines on a change made to a match inside a macro definition. ===begin=== #!/bin/sh -e # Usage: # ./ldst-phys.spatch.sh > ldst-phys.spatch # spatch -sp_file ldst-phys.spatch -dir . | sed -e '/^+/s/\t/ /g' > out.patch # patch -p1 < out.patch for FN in ub uw_le uw_be l_le l_be q_le q_be uw l q; do cat <<EOF @ cpu_matches_ld_${FN} @ expression E1,E2; identifier as; @@ ld${FN}_phys(E1->as,E2) @ other_matches_ld_${FN} depends on !cpu_matches_ld_${FN} @ expression E1,E2; @@ -ld${FN}_phys(E1,E2) +address_space_ld${FN}(E1,E2, MEMTXATTRS_UNSPECIFIED, NULL) EOF done for FN in b w_le w_be l_le l_be q_le q_be w l q; do cat <<EOF @ cpu_matches_st_${FN} @ expression E1,E2,E3; identifier as; @@ st${FN}_phys(E1->as,E2,E3) @ other_matches_st_${FN} depends on !cpu_matches_st_${FN} @ expression E1,E2,E3; @@ -st${FN}_phys(E1,E2,E3) +address_space_st${FN}(E1,E2,E3, MEMTXATTRS_UNSPECIFIED, NULL) EOF done ===endit=== Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.

2015-04-24qmp: Give saner messages related to qmp_capabilities misuseEric Blake1-4/+19
Pretending that QMP doesn't understand a command merely because we are not in the right mode doesn't help first-time users figure out what to do to correct things. Although the documentation for QMP calls out capabilities negotiation, we should also make it clear in our error messages what we were expecting. With this patch, I now get the following transcript: $ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults {"QMP": {"version": {"qemu": {"micro": 93, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} {"execute":"huh"} {"error": {"class": "CommandNotFound", "desc": "The command huh has not been found"}} {"execute":"quit"} {"error": {"class": "CommandNotFound", "desc": "Expecting capabilities negotiation with 'qmp_capabilities' before command 'quit'"}} {"execute":"qmp_capabilities"} {"return": {}} {"execute":"qmp_capabilities"} {"error": {"class": "CommandNotFound", "desc": "Capabilities negotiation is already complete, command 'qmp_capabilities' ignored"}} {"execute":"quit"} {"return": {}} {"timestamp": {"seconds": 1429110729, "microseconds": 181935}, "event": "SHUTDOWN"} Signed-off-by: Eric Blake <eblake@redhat.com> Tested-By: Kashyap Chamarthy <kchamart@redhat.com> Reviewed-by: Paulo Vital <paulo.vital@profitbricks.com> Reviewed-by: John Snow <jsnow@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2015-03-18profiler: Reenable built-in profilerAlexey Kardashevskiy1-3/+3
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile when configured with --enable-profiler. Turned out the profiler has been broken for a while. This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode. This also fixes the compile error. This changes profile_getclock() to return nanoseconds rather than CPU ticks as the "profile" HMP command prints seconds and there is no platform-independent way to get ticks-per-second rate. Since TCG is quite slow and get_clock() returns nanoseconds (fine enough), this should not affect precision much. This removes unused qemu_time_start and tlb_flush_time.

2015-03-17monitor usb: Inline monitor_read_bdrv_key_start()'s first partMarkus Armbruster1-18/+11
monitor_read_bdrv_key_start() does several things: 1. If no key is needed, call completion_cb() and succeed 2. If we're in QMP context, call qerror_report_err() and fail 3. Start reading the key in the monitor. This is two things too many. Inline 1. and 2. into its callers monitor_read_block_device_key() and usb_msd_realize_storage(). Since monitor_read_block_device_key() only ever runs in HMP context, drop 2. there. The next commit will clean up the result in usb_msd_realize_storage().
