2020-11-15nomaintainer: Fix Lesser GPL version numberChetan Pant
There is no "version 2" of the "Lesser" General Public License. It is either "GPL version 2.0" or "Lesser GPL version 2.1". This patch replaces all occurrences of "Lesser GPL version 2" with "Lesser GPL version 2.1" in comment section. This patch contains all the files, whose maintainer I could not get from ‘get_maintainer.pl’ script.

2020-09-09Move QOM typedefs and add missing includesEduardo Habkost
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2020-07-10apic: Report current_count via 'info lapic'Jan Kiszka
This is helpful when debugging stuck guest timers. As we need apic_get_current_count for that, and it is really not emulation specific, move it to apic_common.c and export it.

2019-08-16include: Make headers more self-containedMarkus Armbruster
Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.

2017-03-27Revert "apic: save apic_delivered flag"Paolo Bonzini
This reverts commit 07bfa354772f2de67008dc66c201b627acff0106. The global variable is only read as part of a apic_reset_irq_delivered(); qemu_irq_raise(s->irq); if (!apic_get_irq_delivered()) { sequence, so the value never matters at migration time.

Every configuration has only up to one APIC class and we'll be extending the class with a function that can be called without an instanced object, so a direct access to the class is convenient.

2016-07-20apic: Use apic_id as apic's migration instance_idIgor Mammedov
instance_id is generated by last_used_id + 1 for a given device type so for QEMU with 3 CPUs instance_id for APICs is a seti of [0, 1, 2] When CPU in the middle is hot-removed and migration started APICs with instance_ids 0 and 2 are transferred in migration stream. However target starts with 2 CPUs and APICs' instance_ids are generated from scratch [0, 1] hence migration fails with error Unknown savevm section or instance 'apic' 2 Fix issue by manually registering APIC's vmsd with apic_id as instance_id, in this case instance_id on target will always match instance_id on source as apic_id is the same for a given cpu instance.
