2023-02-23hw/core: Improve error message when machine doesn't provide NMIsMarkus Armbruster
The QERR_ macros are leftovers from the days of "rich" error objects. We've been trying to reduce their remaining use. Get rid of a use of QERR_UNSUPPORTED, and improve the rather vague error message (qemu) nmi Error: this feature or command is not currently supported to Error: machine does not provide NMIs Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20230207075115.1525-5-armbru@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Juan Quintela <quintela@redhat.com>

nmi_monitor_handle is wired to call the x86 nmi handler. So, we can directly use it at call sites. Signed-off-by: Bandan Das <bsd@redhat.com> Message-Id: <1463761717-26558-3-git-send-email-bsd@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-06-22qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster
These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

2015-06-11nmi: Implement inject_nmi() for non-monitor context useXu Wang
Let's introduce a general "inject_nmi()" function that doesn't rely on the cpu index of the monitor, but uses cpu index 0 as default (except for x86). This function can then later be used from a non-monitor context.

2014-08-25cpus: Define callback for QEMU "nmi" commandAlexey Kardashevskiy
This introduces an NMI (Non Maskable Interrupt) interface with a single nmi_monitor_handler() method. A machine or a device can implement it. This searches for an QOM object with this interface and if it is implemented, calls it. The callback implements an action required to cause debug crash dump on in-kernel debugger invocation. The callback returns Error**. This adds a nmi_monitor_handle() helper which walks through all objects to find the interface. The interface method is called for all found instances. This adds support for it in qmp_inject_nmi(). Since no architecture supports it at the moment, there is no change in behaviour. This changes inject-nmi command description for HMP and QMP.
