The test patch is a simple house keeping one to clean up some inadvertent GPLv3 tagging to GPLv2-or-later. I've also increased the timeout for check-tcg due to TCI timeouts.
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 v4 Addressed final comments from Akihiko Added BSD changes Changes for v3: Now we just use GINT_TO_POINTER to wrap the gdb_regnum with a comment this might become and opaque structure later. Either way the plugin shouldn't treat it like anything other than an anonymous handle. The following still need review: tests/tcg: expand insn test case to exercise register API gdbstub: expose api to find registers tests/vm: update openbsd image to 7.4 (0 acks, 1 sobs, 1 tbs) tests/vm: avoid re-building the VM images all the time 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.
