[Linuxppc-users] dmidecode package for ppc64le ?

Wed Nov 1 17:00:23 AEDT 2017

Hi,

Thanks to everyone for answers.  I tried to dig in the serial number; lsvpd did the trick like Dan suggested.

Another info  I’m trying to search is VM UUID;
I know this command:  cat /proc/device-tree/ibm,partition-uuid  works on some lpars (I guess this is due to some firmware level where it works and where not..? )

..but is there some other commands (like on newest AIX level uuid_get cmd https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds5/uuid_get.htm ) that would do the trick?

dmidecode is x86 specific. Most of which does not apply to POWER or PowerISA,

What are you trying to defined out?

A lot of information is in the Aux Vector:

$ LD_SHOW_AUXV=1 /bin/true
AT_DCACHEBSIZE: 0x80
AT_ICACHEBSIZE: 0x80
AT_UCACHEBSIZE: 0x0
AT_SYSINFO_EHDR: 0x3fff97e30000
AT_HWCAP: true_le archpmu vsx arch_2_06 dfp ic_snoop smt mmu fpu altivec ppc64 ppc32
AT_PAGESZ: 65536
AT_CLKTCK: 100
AT_PHDR: 0x37a50040
AT_PHENT: 56
AT_PHNUM: 8
AT_BASE: 0x3fff97e50000
AT_FLAGS: 0x0
AT_ENTRY: 0x37a51a5c
AT_UID: 1007
AT_EUID: 1007
AT_GID: 1007
AT_EGID: 1007
AT_SECURE: 0
AT_RANDOM: 0x3fffd1231912
AT_HWCAP2: htm-nosc vcrypto tar isel ebb dscr htm arch_2_07
AT_EXECFN: /bin/true
AT_PLATFORM: power8
AT_BASE_PLATFORM:power8

This documented in the 64-Bit ELF V2 ABI Specification

With newer GLIBC you can access the AUXV at runtime via getauxval:

https://www.gnu.org/software/libc/manual/html_mono/libc.html#Definition-of-getauxval

With newer GCC you can access AT_PLATFORM and AT_HWCAP/AT_HWCAP2 info via __builtin_cpu_is / __builtin_cpu_supports
