Hi, UPD: 'CPUState::current_tb' was used in that version of QEMU by this code: /* mask must never be zero, except for A20 change call */ cpu_interrupt() has changed almost completely since that time. I'm wondering if checking 'cpu->current_tb' by this code in tb_invalidate_phys_page_range() still makes any sense: if (cpu->interrupt_request && cpu->current_tb) { BTW, I'm not sure about the purpose of this piece of code either :) Kind regards, Sergey |
