Hi, I noticed the following when trying to do some benchmarking for the padlock engine on a VIA Eden CPU using the "openssl speed" command on -current (as of 6 Sept) amd64:
- machdep.xcrypt=0 (should be 15; like i386 port) - no hw.sensors.cpu?.temp (shows up on i386 port) - "openssl speed ... -evp aes-256-cbc" ~ 35MB/s max. (over 415MB/s on i386 port) I have seen an external link (http://www.capnfreedom.com/home/viac7padlockaesbenchmarks) which suggests OpenBSD supports PadLock, so after a rather exhaustive search for relevant CVS commits which suggest changes for VIA CPUs. Last one I could find was this: ========== CVSROOT: /cvs Module name: src Changes by: deraadt@XXXXXXXXXXXXXXX 2009/07/22 14:33:13 Modified files: sys/arch/amd64/amd64: identcpu.c machdep.c sys/arch/amd64/include: cpu.h Log message: via nano cpus are amd64, and so we need machdep.xcrypt ========== Searched the relevant files, and found a single line (Line 571 of sys/arch/amd64/amd64/identcpu.c) to be the culprit. ================ BEGIN DIFF ==================== --- sys/arch/amd64/amd64/identcpu.c 24 Aug 2013 23:45:31 -0000 1.50 +++ sys/arch/amd64/amd64/identcpu.c 6 Sep 2013 05:42:56 -0000 @@ -568,7 +568,7 @@ identifycpu(struct cpu_info *ci) if (!strcmp(cpu_vendor, "AuthenticAMD")) amd64_errata(ci); - if (strncmp(mycpu_model, "VIA Nano processor", 18) == 0) { + if (!strcmp(cpu_vendor, "CentaurHauls")) { ci->cpu_setup = via_nano_setup; #ifndef SMALL_KERNEL strlcpy(ci->ci_sensordev.xname, ci->ci_dev->dv_xname, ================== END DIFF =================== This fix will correct feature recognition and support for VIA Eden and like CPUs.
