2010-10-01QMP: Introduce qmp_call_cmd()Luiz Capitulino
Calls a QObject handler and emits the QMP response, also drops monitor_call_handler() which is now unused. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Directly call QObject handlersLuiz Capitulino
This avoids handle_user_command() calling monitor_call_handler(), which is currently shared with QMP. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Rename monitor_handler_is_async()Luiz Capitulino
Let's follow the convention introduced by the previous commit and call it handler_is_async(). Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Rename monitor_handler_ported()Luiz Capitulino
That name makes no sense anymore, as dispatch tables have been split, a better name is handler_is_qobject(), which really communicates the handler's type. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Drop monitor_cmd_user_only()Luiz Capitulino
This function was only needed when QMP and HMP were sharing dispatch tables, this is no longer true so just drop it. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Drop QMP info from the qemu-monitor.hx fileLuiz Capitulino
QMP has its own dispatch table and documentation file (qmp-commands.hx), we can now drop the following QMP specific info from qemu-monitor.hx: o SQMP/EQMP sections o The qmp_capabilities command o The query-commands command However, note that QObject handlers entries are not being removed. This will only happen when we introduce a proper QMP call interface. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: Small cleanup in handle_qmp_command()Luiz Capitulino
QMP has its own dispatch tables, we can now drop the following checks: o 'info' command: this command doesn't exist in QMP's dispatch table, the right thing will happen when it's issued by a client (ie. command not found error) o monitor_handler_ported(): all QMP handlers are 'ported', no need to check for that o monitor_cmd_user_only(): no HMP handler will exist in QMP's dispatch tables, that's why we have split them after all :-) Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: Simplify do_info_commands()Luiz Capitulino
We now iterate over QMP's dispatch tables, no need to check for QMP-only handlers anymore. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: Introduce query commands dispatch tableLuiz Capitulino
The new table is a copy of HMP's table, containing only QObject handlers. In the near future HMP will be making QMP calls and then we will be able to drop QObject handlers from HMP's table. From now on, QMP and HMP have different query command dispatch tables. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: Introduce command dispatch tableLuiz Capitulino
Also update QMP functions to use it. The table is generated from the qmp-commands.hx file. From now on, QMP and HMP have different command dispatch tables. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: Introduce qmp_find_cmd()Luiz Capitulino
Next commit needs this new function: it will introduce the the QMP's command dispatch table and qmp_find_cmd() will be used to search on it. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Introduce the qmp-commands.hx fileLuiz Capitulino
This file contains a copy of the following information from the qemu-monitor.hx file: o QObject handlers entries o QMP documentation (all SQMP/EQMP sections) Right now it's only used to generate the QMP docs in QMP/, but next commits will turn this into QMP's command dispatch table. It's important to note that QObject handlers entries are going to get duplicated: they will exist in both QMP's and HMP's dispatch tables. This will be fixed in the near future, when we add a proper QMP call interface and HMP is converted to use it. This way we can completely drop QObject handlers entries from HMP's tables. NOTE: HMP specific constructions, like "q|quit", have been dropped. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Convert do_info() back to HMPLuiz Capitulino
This is a HMP specific handler, it makes no sense to have it under QMP. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Drop is_async_return()Luiz Capitulino
If I understood it correcty, the is_async_return() logic was only used to prevent QMP from issuing duplicated success responses for asynchronous handlers. However, QMP doesn't use do_info() anymore so this is dead logic and (hopefully) can be safely dropped. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Drop QMP bits from do_info()Luiz Capitulino
As of last commit, QMP doesn't use do_info() anymore. Simplify it. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: Don't use do_info()Luiz Capitulino
Since its inception, QMP has been using HMP's do_info() function to run query commands. This was a bad choice, as it made do_info() more complex and contributed to couple QMP and HMP. This commit fixes that by doing the following changes: 1. Introduce qmp_find_query_cmd() and use it to directly lookup the info_cmds table 2. Introduce qmp_call_query_cmd() so that QMP code is able to call query handlers without using do_info() 3. Drop do_info() usage (via monitor_find_command("info")) We need all the three changes in one shot so that we don't break the calling of query commands in QMP. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01QMP: handle_qmp_command(): Move 'cmd' sanity checkLuiz Capitulino
Next commit will change how query commands are handled in a way that the 'cmd' sanity check is also going to be needed for query commands handling. Let's move it out of the else body then. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Monitor: Introduce search_dispatch_table()Luiz Capitulino
It's a generic version of monitor_find_command() which searches the dispatch table passed as an argument. Future commits will introduce new dispatch tables, so we need common code to search them. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01disable guest-provided stats on "info balloon" commandEduardo Habkost
The addition of memory stats reporting to the virtio balloon causes the 'info balloon' command to become asynchronous. This is a regression because in some cases it can hang the user monitor. This is an alternative to Adam Litke's patch. Adam's patch disabled the corresponding (guest-visible) virtio feature bit, causing issues for migration. Original discussion is available at: http://marc.info/?l=qemu-devel&m=128448124328314&w=2 Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Acked-by: Adam Litke <agl@us.ibm.com Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Add option to turn on JSON pretty printing in monitorDaniel P. Berrange
Expaned '-mon' arg to allow a 'pretty=on' flag. This makes the monitor pretty print its replies to easy human debugging / reading Signed-off-by: Daniel P. Berrange <berrange@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-10-01Add support for JSON pretty printingDaniel P. Berrange
The monitor does not pretty-print JSON output, so that everything will be on a single line reply. When JSON docs get large this is quite unpleasant to read. For the future command line capabilities query ability, huge JSON docs will be available. This needs the ability to pretty-print. This introduces a new API qobject_to_json_pretty() that does a minimal indentation of list and dict members. As an example, this makes {"QMP": {"version": {"micro": 50, "minor": 12, "package": "", "major": 0}, "capabilities": []}} Output as { "QMP": { "version": { "micro": 50, "minor": 12, "package": "", "major": 0 }, "capabilities": [ ] } } NB: this is not turned on for the QMP monitor.

2010-09-29pulse-audio: fix bug on updating rposWu Fengguang
Fix a rpos coordination bug between qpa_run_out() and qpa_thread_out(), which shows up as playback noises. qpa_run_out() qpa_thread_out loop N critical section 1 qpa_run_out() qpa_thread_out loop N doing pa_simple_write() qpa_run_out() qpa_thread_out loop N doing pa_simple_write() qpa_thread_out loop N critical section 2 qpa_thread_out loop N+1 critical section 1 qpa_run_out() qpa_thread_out loop N+1 doing pa_simple_write() In the above scheme, "qpa_thread_out loop N+1 critical section 1" will get the same rpos as the one used by "qpa_thread_out loop N critical section 1". So it will be reading dead samples from the old rpos. The rpos can only be updated back to qpa_thread_out when there is a qpa_run_out() run between two qpa_thread_out loops. normal sequence: qpa_thread_out: hw->rpos (X0) => local rpos => pa->rpos (X1) qpa_run_out: pa->rpos (X1) => hw->rpos (X1) qpa_thread_out: hw->rpos (X1) => local rpos => pa->rpos (X2) buggy sequence: qpa_thread_out: hw->rpos (X0) => local rpos => pa->rpos (X1) qpa_thread_out: hw->rpos (X0) => local rpos => pa->rpos (X1') Obviously qpa_run_out() shall be called at least once between any two qpa_thread_out loops (after pa->rpos is set), in order for the new qpa_thread_out loop to see the updated rpos. Setting pa->live to 0 does the trick. The next loop will have to wait for one qpa_run_out() invocation in order to get a non-zero pa->live and proceed.

2010-09-25Introduce qemu_madvise()Andreas Färber
vl.c has a Sun-specific hack to supply a prototype for madvise(), but the call site has apparently moved to arch_init.c. Haiku doesn't implement madvise() in favor of posix_madvise(). OpenBSD and Solaris 10 don't implement posix_madvise() but madvise(). MinGW implements neither. Check for madvise() and posix_madvise() in configure and supply qemu_madvise() as wrapper. Prefer madvise() over posix_madvise() due to flag availability. Convert all callers to use qemu_madvise() and QEMU_MADV_*. Note that on Solaris the warning is fixed by moving the madvise() prototype, not by qemu_madvise() itself. It helps with porting though, and it simplifies most call sites. v7 -> v8: * Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl. v6 -> v7: * Adopt madvise() rather than posix_madvise() semantics for returning errors. * Use EINVAL in place of ENOTSUP. v5 -> v6: * Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID. Spotted by Blue Swirl. v4 -> v5: * Introduce QEMU_MADV_INVALID, suggested by Alexander Graf. Note that this relies on -1 not being a valid advice value. v3 -> v4: * Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl. This will currently break the check in kvm-all.c by calling madvise() with a supported flag, which will not fail. Ideas/patches welcome. v2 -> v3: * Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf. * Add configure check for madvise(), too. Add defines to Makefile, not QEMU_CFLAGS. Convert all callers, untested. Suggested by Blue Swirl. * Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf. * Display configure check results. v1 -> v2: * Don't rely on posix_madvise() availability, add qemu_madvise(). Suggested by Blue Swirl.

By moving the definition of GCC_ATTR and GCC_FMT_ATTR from audio_int.h to qemu-common.h these macros are now generally available for further patches which add the gcc format attribute. Newer gcc versions support format gnu_printf which is better suited for use in QEMU than format printf (QEMU always uses standard format strings (even with mingw32)).

2010-09-21trace: Fix user emulator dependency on trace objectsAndreas Färber
On a clean build, after generating trace.h, make would recurse into *-*-user without a clue how to build ../trace.o (added to $(obj-y) in Makefile.target) since its generation rule is in the main Makefile. The softmmus are seemingly unaffected because the $(TOOLS), which each have a dependency on $(trace-obj-y), are built first for the build-all target. Add a dependency on $(trace-obj-y) for %-user, as done for the qemu-* tools. Let's be paranoid and do the same for %-softmmu while at it, just in case someone messes with $(TOOLS) or calls the Makefile target directly.

2010-09-21ide: propagate the required alignmentChristoph Hellwig
IDE is a bit ugly in this respect. For one it doesn't really keep track of a sector size - most of the protocol is in units of 512 bytes, and we assume 2048 bytes for CDROMs which is correct most of the time. Second IDE allocates an I/O buffer long before we know if we're dealing with a CDROM or not, so increase the alignment for the io_buffer unconditionally.
