2017-08-08maint: Include bug-reporting info in --help outputEric Blake1-0/+2
These days, many programs are including a bug-reporting address, or better yet, a link to the project web site, at the tail of their --help output. However, we were not very consistent at doing so: only qemu-nbd and qemu-qa mentioned anything, with the latter pointing to an individual person instead of the project. Add a new #define that sets up a uniform string, mentioning both bug reporting instructions and overall project details, and which a downstream vendor could tweak if they want bugs to go to a downstream database. Then use it in all of our binaries which have --help output. The canned text intentionally references http:// instead of https:// because our https website currently causes certificate errors in some browsers. That can be tweaked later once we have resolved the web site issued. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P.

2017-07-21bsd-user/main.c: Fix unused variable warningPeter Maydell1-3/+4
On OpenBSD the compiler warns: bsd-user/main.c:622:21: warning: variable 'sig' set but not used [-Wunused-but-set-variable] This is because a lot of the signal delivery code is #if-0'd out as unused. Reshuffle #ifdefs a bit to silence the warning. (We make the minimum change here rather than removing all the bsd-user patchset which should make this all work correctly and there's no point giving them an awkward rebase task.)

2016-10-12trace: provide mechanism for registering trace eventsDaniel P. Berrange1-0/+1
Remove the notion of there being a single global array of trace events, by introducing a method for registering groups of events. The module_call_init() needs to be invoked at the start of any program that wants to make use of the trace support. Currently this covers system emulators qemu-nbd, qemu-img and qemu-io. [Squashed the following fix from Daniel P. Berrange <berrange@redhat.com>: linux-user/bsd-user: initialize trace events subsystem The bsd-user/linux-user programs make use of the CPU emulation code and this now requires that the trace events subsystem is enabled, otherwise it'll crash trying to allocate an empty trace events bitmap for the CPU object. --Stefan] Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Daniel P.

2016-06-20log: Fix qemu_set_log_filename() error handlingMarkus Armbruster1-1/+2
When qemu_set_log_filename() detects an invalid file name, it reports an error, closes the log file (if any), and starts logging to stderr (unless daemonized or nothing is being logged). This is wrong. Asking for an invalid log file on the command line should be fatal. Asking for one in the monitor should fail without messing up an existing logfile. Fix by converting qemu_set_log_filename() to Error. Pass it &error_fatal, except for hmp_logfile report errors. This also permits testing without a subprocess, so do that.

2013-05-02target-i386: Replace cpuid_*features fields with a feature word arrayEduardo Habkost1-2/+2
This replaces the feature-bit fields on both X86CPU and x86_def_t structs with an array. With this, we will be able to simplify code that simply does the same operation on all feature words (e.g. kvm_check_features_against_host(), filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit property lookup/registration, and the proposed "feature-words" property) The following field replacements were made on X86CPU and x86_def_t: (cpuid_)features -> features[FEAT_1_EDX] (cpuid_)ext_features -> features[FEAT_1_ECX] (cpuid_)ext2_features -> features[FEAT_8000_0001_EDX] (cpuid_)ext3_features -> features[FEAT_8000_0001_ECX] (cpuid_)ext4_features -> features[FEAT_C000_0001_EDX] (cpuid_)kvm_features -> features[FEAT_KVM] (cpuid_)svm_features -> features[FEAT_SVM] (cpuid_)7_0_ebx_features -> features[FEAT_7_0_EBX] Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-26qemu-log: default to stderr for logging outputPeter Maydell1-10/+8
Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

Rename the public-facing function cpu_set_log to qemu_set_log. This requires us to rename the internal-only qemu_set_log() to do_qemu_set_log(). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

Rename cpu_str_to_log_mask() to qemu_str_to_log_mask(), since the qemu_log functionality is no longer restricted to TCG CPU debug logging. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2013-02-16qemu-log: Abstract out "print usage message about valid log categories"Peter Maydell1-5/+1
Abstract out the "print a human readable list of all the valid log categories" functionality which is currently duplicated in three separate places. (We leave the monitor.c help_cmd() implementation as-is since it wants to send the message to the monitor and add its own information.)

2013-02-01linux-user: bsd-user: Don't reset X86CPU twiceAndreas Färber1-1/+1
Since commit 65dee38052597b6285eb208125369f01b29ba6c1 (target-i386: move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through cpu_init() but was still reset immediately after in linux-user and bsd-user. Clean this up. Similarly in linux-user/syscall.c it is also reset after cpu_copy(). But that's a bug of its own, fixing which poses a semantic change.
