2019-02-18build-sys: move qmp-introspect per targetMarc-André Lureau1-0/+2
The following patches are going to introduce per-target #ifdef in the schemas. The introspection data is statically generated once, and must thus be built per-target to reflect target-specific configuration. Drop "do_test_visitor_in_qmp_introspect(&qmp_schema_qlit)" since the schema is no longer in a common object. It is covered by the per-target query-qmp-schema test instead.

2019-01-24trace: add ability to do simple printf logging via systemtapDaniel P. Berrangé1-1/+10
The dtrace systemtap trace backend for QEMU is very powerful but it is also somewhat unfriendly to users who aren't familiar with systemtap, or who don't need its power right now. stap -e "....some strange script...." The 'log' backend for QEMU by comparison is very crude but incredibly easy to use: $ qemu -d trace:qio* ...some args... 23266@1547735759.137292:qio_channel_socket_new Socket new ioc=0x563a8a39d400 23266@1547735759.137305:qio_task_new Task new task=0x563a891d0570 source=0x563a8a39d400 func=0x563a86f1e6c0 opaque=0x563a89078000 23266@1547735759.137326:qio_task_thread_start Task thread start task=0x563a891d0570 worker=0x563a86f1ce50 opaque=0x563a891d9d90 23273@1547735759.137491:qio_task_thread_run Task thread run task=0x563a891d0570 23273@1547735759.137503:qio_channel_socket_connect_sync Socket connect sync ioc=0x563a8a39d400 addr=0x563a891d9d90 23273@1547735759.138108:qio_channel_socket_connect_fail Socket connect fail ioc=0x563a8a39d400 This commit introduces a way to do simple printf style logging of probe points using systemtap. In particular it creates another set of tapsets, one per emulator: /usr/share/systemtap/tapset/qemu-*-log.stp These pre-define probe functions which simply call printf() on their arguments. The printf() format string is taken from the normal trace-events files, with a little munging to the format specifiers to cope with systemtap's more restrictive syntax. With this you can now do $ stap -e 'probe qemu.system.x86_64.log.qio*{}' 22806@1547735341399856820 qio_channel_socket_new Socket new ioc=0x56135d1d7c00 22806@1547735341399862570 qio_task_new Task new task=0x56135cd66eb0 source=0x56135d1d7c00 func=0x56135af746c0 opaque=0x56135bf06400 22806@1547735341399865943 qio_task_thread_start Task thread start task=0x56135cd66eb0 worker=0x56135af72e50 opaque=0x56135c071d70 22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0 We go one step further though and introduce a 'qemu-trace-stap' tool to make this even easier $ qemu-trace-stap run qemu-system-x86_64 'qio*' 22806@1547735341399856820 qio_channel_socket_new Socket new ioc=0x56135d1d7c00 22806@1547735341399862570 qio_task_new Task new task=0x56135cd66eb0 source=0x56135d1d7c00 func=0x56135af746c0 opaque=0x56135bf06400 22806@1547735341399865943 qio_task_thread_start Task thread start task=0x56135cd66eb0 worker=0x56135af72e50 opaque=0x56135c071d70 22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0 This tool is clever in that it will automatically change the SYSTEMTAP_TAPSET env variable to point to the directory containing the right set of probes for the QEMU binary path you give it. This is useful if you have QEMU installed in /usr but are trying to test and trace a binary in /home/berrange/usr/qemu-git. In that case you'd do $ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*' And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset is used for the trace session The 'qemu-trace-stap' script takes a verbose arg so you can understand what it is running $ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*' Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64' Compiling script 'probe qemu.system.x86_64.log.qio* {}' Running script, <Ctrl>-c to quit ...trace output... It can enable multiple probes at once $ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*' By default it monitors all existing running processes and all future launched proceses.

2019-01-14build-sys: use a separate slirp-obj-y && slirp.moMarc-André Lureau1-1/+4
This will allow to have cflags for the whole slirp.mo -objs. It makes it possible to build tests that links only with slirp-obj-y (and not the whole common-obj). It is also a step towards building slirp as a shared library, although this requires a bit more thoughts to build with net/slirp.o (CONFIG_SLIRP would need to be 'm') and other build issues.

2018-06-29dump: add Windows dump format to dump-guest-memoryViktor Prutyanov1-0/+1
This patch adds Windows crashdumping feature. Now QEMU can produce ELF-dump containing Windows crashdump header, which can help to convert to a valid WinDbg-understandable crashdump file, or immediately create such file. The crashdump will be obtained by joining physical memory dump and 8K header exposed through vmcoreinfo/fw_cfg device by guest driver at BSOD time. Option '-w' was added to dump-guest-memory command. At the moment, only x64 configuration is supported.

2018-03-23make: switch from -I to -iquoteMichael S. Tsirkin1-2/+2
Our rule right now is to use <> for external headers, "" for internal ones. The idea was to avoid conflicts between e.g. a system file named <trace.h> and an internal one by the same name. Unfortunately we use -I compiler flag so it does not help: a system file doing #include <trace.h> will still pick up ours first. To fix, switch to -iquote which is supported by both gcc and clang and only affects #include "" directives. As a side effect, this catches any future uses of #include <> for internal headers.

More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-10-06rules.mak: quiet-command: Split command name and args to printPeter Maydell1-9/+9
The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".

2016-09-06s390x/cpumodel: generate CPU feature lists for CPU modelsMichael Mueller1-1/+1
This patch introduces the helper "gen-features" which allows to generate feature list definitions at compile time. Its flexibility is better and the error-proneness is lower when compared to static programming time added statements. The helper includes "target-s390x/cpu_features.h" to be able to use named facility bits instead of numbers. The generated defines will be used for the definition of CPU models. We generate feature lists for each HW generation and GA for EC models. BC models are always based on a EC version and have no separate definitions. Base features: Features we expect to be always available in sane setups. Migration safe - will never change. Can be seen as "minimum features required for a CPU model". Default features: Features we expect to be stable and around in latest setups (e.g. having KVM support) - not migration safe. Max features: All supported features that are theoretically allowed for a CPU model. Exceeding these features could otherwise produce problems with IBC (instruction blocking controls) in KVM.

2016-06-26linux-user: Create a hostdep.h for each host architecturePeter Maydell1-4/+1
In commit 4d330cee37a21 a new hostdep.h file was added, with the intent that host architectures which needed one could provide it, and the build system would automatically fall back to a generic version if there was no version for the host architecture. Although this works, it has a flaw: if a subsequent commit switches an architecture from "uses generic/hostdep.h" to "uses its own hostdep.h" nothing in the makefile dependencies notices this and so doing a rebuild without a manual 'make clean' will fail. So we drop the idea of having a 'generic' version in favour of every architecture we support having its own hostdep.h, even if it doesn't have anything in it. (There are only thirteen of these.) If the dependency files claim that an object file depends on a nonexistent file, our dependency system means that make will rebuild the object file, and regenerate the dependencies in the process. So moving between trees prior to this commit and trees after this commit works without requiring a 'make clean'.

2016-05-27linux-user: Provide safe_syscall for fixing races between signals and syscallsTimothy E Baldwin1-1/+6
If a signal is delivered immediately before a blocking system call the handler will only be called after the system call returns, which may be a long time later or never. This is fixed by using a function (safe_syscall) that checks if a guest signal is pending prior to making a system call, and if so does not call the system call and returns -TARGET_ERESTARTSYS. If a signal is received between the check and the system call host_signal_handler() rewinds execution to before the check. This rewinding has the effect of closing the race window so that safe_syscall will reliably either (a) go into the host syscall with no unprocessed guest signals pending or or (b) return -TARGET_ERESTARTSYS so that the caller can deal with the signals. Implementing this requires a per-host-architecture assembly language fragment. This will also resolve the mishandling of the SA_RESTART flag where we would restart a host system call and not call the guest signal handler until the syscall finally completed -- syscall restarting now always happens at the guest syscall level so the guest signal handler will run. (The host syscall will never be restarted because if the host kernel rewinds the PC to point at the syscall insn for a restart then our host_signal_handler() will see this and arrange the guest PC rewind.) This commit contains the infrastructure for implementing safe_syscall and the assembly language fragment for x86-64, but does not change any syscalls to use it.

2015-12-18io: add abstract QIOChannel classesDaniel P. Berrange1-0/+2
Start the new generic I/O channel framework by defining a QIOChannel abstract base class. This is designed to feel similar to GLib's GIOChannel, but with the addition of support for using iovecs, qemu error reporting, file descriptor passing, coroutine integration and use of the QOM framework for easier sub-classing. The intention is that anywhere in QEMU that almost anywhere that deals with sockets will use this new I/O infrastructure, so that it becomes trivial to then layer in support for TLS encryption. This will at least include the VNC server, char device backend and migration code. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
