Could you paste in the name of the patch in the description? +x86_init_early(BIT(X86_SUBARCH_INTEL_MID), NULL, NULL, + x86_intel_mid_early_setup); Is an example, so users of the subarch. Likewise the macro helpers to make these smaller, see x86_init_early_all() on the patch "x86/init: add linker table support". And then of course the checkers: +static bool x86_init_fn_supports_subarch(struct x86_init_fn *fn) +{ + if (!fn->supp_hardware_subarch) { + pr_err("Init sequence fails to declares any supported subarchs: %pF\n", fn->early_init); + WARN_ON(1); + } + if (BIT(boot_params.hdr.hardware_subarch) & fn->supp_hardware_subarch) + return true; + return false; +} Luis _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
