Subject: [PATCH V11 0/3] powernv : Add support for OPAL-OCC command/response interface
Date: Thu, 10 Aug 2017 09:01:17 +0530 [thread overview]
Message-ID: <1502335880-30686-1-git-send-email-shilpa.bhat@linux.vnet.ibm.com> (raw)
In P9, OCC (On-Chip-Controller) supports shared memory based
commad-response interface. Within the shared memory there is an OPAL
command buffer and OCC response buffer that can be used to send
inband commands to OCC. The following commands are supported:
1) Set system powercap
2) Set CPU-GPU power shifting ratio
3) Clear min/max for OCC sensor groups
Changes from V10:
- Rebased on powerpc-next
- Add sysfs interface instead of IOCTL
(Skiboot patch for Patch3 is posted below:
https://lists.ozlabs.org/pipermail/skiboot/2017-August/008553.html )
