== Comment: #1 - Application Cdeadmin <cdead...@us.ibm.com> - 2017-03-28 03:25:08 == ==== State: Open by: fekareem on 28 March 2017 03:17:53 ==== Problem Description ====================== /sys/kernel/debug/powerpc/scom missing and hence getscom and putscom are not working. Seems like Ubuntu compiled the kernel without the CONFIG_PPC_SCOM option I discussed with Mahesh Salgaonkar and seems like Ubuntu needs to build kernel with following config options to get scoms to work CONFIG_PPC_SCOM=y CONFIG_SCOM_DEBUGFS=y Please mirror bug to Ubuntu root@grsfp23p01:~# getscom -l Error accessing sysfs scom directory: No such file or directory root@grsfp23p01:~# root@grsfp23p01:~# ls /sys/kernel/debug/powerpc/scom ls: cannot access '/sys/kernel/debug/powerpc/scom': No such file or directory root@grsfp23p01:~# ls /sys/kernel/debug/powerpc eeh_enable lpc PCI0001 PCI0003 PCI0005 PCI0033 PCI0035 eeh_max_freezes PCI0000 PCI0002 PCI0004 PCI0030 PCI0034 root@grsfp23p01:~# root@grsfp23p01:~# cat /etc/os-release NAME="Ubuntu" VERSION="17.04 (Zesty Zapus)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu Zesty Zapus (development branch)" VERSION_ID="17.04" HOME_URL="https://www.ubuntu.com/"; SUPPORT_URL="https://help.ubuntu.com/"; BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"; PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"; VERSION_CODENAME=zesty UBUNTU_CODENAME=zesty root@grsfp23p01:~# == Comment: #2 - MAHESH J.
