From 7f4730d5841fd9ee528b6aa8e09748bc6b8b05ee Mon Sep 17 00:00:00 2001 From: Vasant Hegde Date: Fri, 13 Jan 2017 14:08:25 +0530 Subject: hdat: Grab system model name from HDAT when available Latest spec added system model information to IPL PARAMS ntuple. Grab this information when available instead of using hardcoded table (machine_table). Its better to parse all IPL params in one place. But on P8 we depend on model information ..which we get from sysvpd_parse(). Hence for now I've added code inside sysvpd_parse().
