* add cpu_test_interrupt()/cpu_set_interrupt() helpers and use them tree wideIgor Mammedov2025-08-291-1/+1
| | | | | | | | | | | | | | | | The helpers form load-acquire/store-release pair and ensure that appropriate barriers are in place in case checks happen outside of BQL. Use them to replace open-coded checkers/setters across the code, to make sure that barriers are not missed. Helpers also make code a bit more readable.

* target/sparc: Move cpu_put_fsr(env, 0) call to resetPeter Maydell2024-11-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently we call cpu_put_fsr(0) in sparc_cpu_realizefn(), which initializes various fields in the CPU struct: * fsr_cexc_ftt * fcc[] * fsr_qne * fsr It also sets the rounding mode in env->fp_status. This is largely pointless, because when we later reset the CPU this will zero out all the fields up until the "end_reset_fields" label, which includes all of these (but not fp_status!) Move the cpu_put_fsr(env, 0) call to reset, because that expresses the logical requirement: we want to reset FSR to 0 on every reset. This isn't a behaviour change because the fields are all zero anyway.

* target: Set TCGCPUOps::cpu_exec_halt to target's has_work implementationPeter Maydell2024-07-111-0/+1
| | | | | | | | | | | | | | | | | | Currently the TCGCPUOps::cpu_exec_halt method is optional, and if it is not set then the default is to call the CPUClass::has_work method (which has an identical function signature). We would like to make the cpu_exec_halt method mandatory so we can remove the runtime check and fallback handling. In preparation for that, make all the targets which don't need special handling in their cpu_exec_halt set it to their cpu_has_work implementation instead of leaving it unset. (This is every target except for arm and i386.) In the riscv case this requires us to make the function not be local to the source file it's defined in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The output of "-cpu help" is currently rather confusing to the users: It might not be fully clear which part of the output defines the CPU names since the CPU names contain white spaces (which we later have to convert into dashes internally). At best it's at least a nuisance since the users might need to specify the CPU names with quoting on the command line if they are not aware of the fact that the CPU names could be written with dashes instead. So let's finally clean up this mess by using dashes instead of white spaces for the CPU names, like we're doing it internally later (and like we're doing it in most other targets of QEMU). Note that it is still possible to pass the CPU names with spaces to the "-cpu" option, since sparc_cpu_type_name() still translates those to "-".

The "+" character was meant to be included in this set, so we had to add a hack there to still allow the legacy names of POWER and Sparc64 CPUs. However, instead of putting such a hack in the common QOM code, there is a much better place to do this: The sparc_cpu_class_by_name() function which is used to look up the names of all Sparc CPUs. Thus let's finally get rid of the "+" in the Sparc CPU names, and provide backward compatibility for the old names via some simple checks in the sparc_cpu_class_by_name() function.

| | | | | | | | | | | | | | | | | | | | | | | | | We pass a ResetType argument to the Resettable class enter phase method, but we don't pass it to hold and exit, even though the callsites have it readily available. This means that if a device cared about the ResetType it would need to record it in the enter phase method to use later on. Pass the type to all three of the phase methods to avoid having to do that.
