Kernel/kvm patches are already in[1]. Watchpoint on powerpc TCG guest is not supported and thus 2nd DAWR is not enabled for TCG mode. Patches apply fine on qemu/master branch (9e2e9fe3df9f). v2: https://lore.kernel.org/r/20210329041906.213991-1-ravi.bangoria@linux.ibm.com v2->v3: - Don't introduce pa_features_310[], instead, reuse pa_features_300[] for 3.1 guests, as there is no difference between initial values of them atm. - Call gen_spr_book3s_310_dbg() from init_proc_POWER10() instead of init_proc_POWER8(). Also, Don't call gen_spr_book3s_207_dbg() from gen_spr_book3s_310_dbg() as init_proc_POWER10() already calls it. v1: https://lore.kernel.org/r/20200723104220.314671-1-ravi.bangoria@linux.ibm.com [Apologies for long gap] v1->v2: - Introduce machine capability cap-dawr1 to enable/disable the feature. By default, 2nd DAWR is OFF for guests even when host kvm supports it. User has to manually enable it with -machine cap-dawr1=on if he wishes to use it. - Split the header file changes into separate patch.
