Hi there, My portmsaster run just broke on the recent openblas upgrade, with version stamp in head/math/openblas/Makefile 409114 26-02-18 16:35:48Z rakuco. Now that I’ve hacked on this to make it build, I remember having done something like this the last time, so perhaps nothing has actually changed in this respect, there’s just been a version increase that still doesn’t know about my CPU.
My build/target machine is, according to sysctl: hw.machine: amd64 hw.model: AMD A6-3500 APU with Radeon(tm) HD Graphics hw.ncpu: 3 The auto-config system for openblas has determined that this is (in config.h): #define AMD_UNKNOWN but also #define CORE_BARCELONA #define CHAR_CORENAME “BARCELONA” So on the assumption that the AMD_UNKNOWN should be BARCELONA, I have tweaked cpuid_x86.c to add case 3 along with case 1 and case 10 in the switch(exfamily) to return CPUTYPE_BARCELONA. I’m not sure if it wouldn’t have been better to slide that in with case 6, because model=1 and support_avx()->0, so that would have worked too. the full set of get_cputype() values for my machine are: family=0xf, exfamily=0x3, model=0x1, exmodel=0x0, support_avx=0 The code in cpuid_x86.c thinks that NUM_CORES is 1, despite the sysctl information above, so I guess that only one core is going to be used, but since this is not a high performance machine and is generally thermally challenged, I’m not too concerned about that. Just want it to build at all. With this couple of tweaks the math/openblas port seems to have built OK, so I hope that this change can be included in the port or the up-stream so that I don’t have to remember to do this all again next time!
