2020-03-17cpu: Use DeviceClass reset instead of a special CPUClass resetPeter Maydell
The CPUClass has a 'reset' method. This is a legacy from when TYPE_CPU used not to inherit from TYPE_DEVICE. We don't need it any more, as we can simply use the TYPE_DEVICE reset. The 'cpu_reset()' function is kept as the API which most places use to reset a CPU; it is now a wrapper which calls device_cold_reset() and then the tracepoint function. This change should not cause CPU objects to be reset more often than they are at the moment, because: * nobody is directly calling device_cold_reset() or qdev_reset_all() on CPU objects * no CPU object is on a qbus, so they will not be reset either by somebody calling qbus_reset_all()/bus_cold_reset(), or by the main "reset sysbus and everything in the qbus tree" reset that most devices are reset by Note that this does not change the need for each machine or whatever to use qemu_register_reset() to arrange to call cpu_reset() -- that is necessary because CPU objects are not on any qbus, so they don't get reset when the qbus tree rooted at the sysbus bus is reset, and this isn't being changed here. All the changes to the files under target/ were made using the included Coccinelle script, except: (1) the deletion of the now-inaccurate and not terribly useful "CPUClass::reset" comments was done with a perl one-liner afterwards: perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c (2) this bit of the s390 change was done by hand, because the Coccinelle script is not sophisticated enough to handle the parent_reset call being inside another function: | @@ -96,8 +96,9 @@ static void s390_cpu_reset(CPUState *s, cpu_reset_type type) | S390CPU *cpu = S390_CPU(s); | S390CPUClass *scc = S390_CPU_GET_CLASS(cpu); | CPUS390XState *env = &cpu->env; |+ DeviceState *dev = DEVICE(s); | |- scc->parent_reset(s); |+ scc->parent_reset(dev); | cpu->env.sigp_order = 0; | s390_cpu_set_state(S390_CPU_STATE_STOPPED, cpu); Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20200303100511.5498-1-peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2019-04-18qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster
CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

2018-04-11icount: fix cpu_restore_state_from_tb for non-tb-exit casesPavel Dovgalyuk
In icount mode, instructions that access io memory spaces in the middle of the translation block invoke TB recompilation. After recompilation, such instructions become last in the TB and are allowed to access io memory spaces. When the code includes instruction like i386 'xchg eax, 0xffffd080' which accesses APIC, QEMU goes into an infinite loop of the recompilation. This instruction includes two memory accesses - one read and one write. After the first access, APIC calls cpu_report_tpr_access, which restores the CPU state to get the current eip. But cpu_restore_state_from_tb resets the cpu->can_do_io flag which makes the second memory access invalid. Therefore the second memory access causes a recompilation of the block. Then these operations repeat again and again. This patch moves resetting cpu->can_do_io flag from cpu_restore_state_from_tb to cpu_loop_exit* functions. It also adds a parameter for cpu_restore_state which controls restoring icount. There is no need to restore icount when we only query CPU state without breaking the TB. Restoring it in such cases leads to the incorrect flow of the virtual time. In most cases new parameter is true (icount should be recalculated). But there are two cases in i386 and openrisc when the CPU state is only queried without the need to break the TB. This patch fixes both of these cases.

2018-03-19cpu: add CPU_RESOLVING_TYPE macroIgor Mammedov
it will be used for providing to cpu name resolving class for parsing cpu model for system and user emulation code. Along with change add target to null-machine tests, so that when switch to CPU_RESOLVING_TYPE happens, it would ensure that null-machine usecase still works.

2018-02-21target/*/cpu.h: remove softfloat.hAlex Bennée
As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.
