Hi, Currently we register all vCPUs to the global 'cpus_queue' queue, however we can not discriminate per accelerator or per target architecture (which might happen in a soon future). This series tries to add an accelerator discriminator, so accelerator specific code can iterate on its own vCPUs. This is required to run a pair of HW + SW accelerators like the (HVF, TCG) or (KVM, TCG) combinations. Otherwise, i.e. the HVF core code could iterate on TCG vCPUs... To keep it simple and not refactor heavily the code base, we introduce the CPU_FOREACH_TCG/HVF/KVM() macros, only defined for each accelerator. This is just a RFC to get some thoughts whether this is heading in the correct direction or not ;) Regards, Phil.
