I've also increased the timeout for check-tcg due to TCI timesouts. The main bulk of this series is register reading support for TCG plugins. The main change to the API is that the get/read_register functions are now implicitly vCPU context only so have dropped the vcpu index parameter and use current_cpu instead. This avoids the need for locking the gdbstub structures in case there is a cross-vCPU access. I've pulled in some patches from Pierrick's inline enhancement series that allow this to happen (making sure the init callback is in the vCPU context). Changes for v2: After lots of back and forth in the last review I've dropped trying to be clever with CPUClass as it was pointed out even with a common CPUClass we might see different sets of registers depending on what features are enabled on a CPU. Now I just have a hash per CPUState (stored in the new CPUPluginState structure) with a simple reg_num key. I also fixed a bug in nios2-linux-user. The following still need review: contrib/plugins: extend execlog to track register changes tests/tcg: expand insn test case to exercise register API plugins: create CPUPluginState and migrate plugin_mask gdbstub: expose api to find registers linux-user: ensure nios2 processes queued work tests/tcg: bump TCG test timeout to 120s But I'd like to get this merged soon so its not a mad rush before soft freeze and so we can get the new inline support stabilised and merged.
