2017-09-15hdata: Parse NVLink informationOliver O'Halloran1-0/+168
Add the per-chip structures that descibe how the A-Bus/NVLink/OpenCAPI phy is configured. This generates the npu@xyz nodes for each chip on systems that support it. Signed-off-by: Oliver O'Halloran <oohall@gmail.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2017-09-15hdata: Add xscom_to_pcrd()Oliver O'Halloran1-0/+39
Iterating the SPPCRD structures (per chip data) is a fairly common operation in the HDAT parser. Iterating the tuples directly is somewhat irritating since we need to check for disabled chips, etc on every pass. A better way to handle this is to iterate throught he xscom nodes (generated from the SPPCRD data) and map from the xscom node to the originating structure. This patch adds a function to do that.

2017-08-22HDAT/device-tree: only add lid-type on pre-POWER9 systemsStewart Smith1-2/+4
Largely a relic of back when we had multiple entry points into OPAL depending on which mechanism on an FSP we were using to get loaded, this isn't needed on modern P9 as we only have one entry point (we don't do the PHYP LID hack).

90% of what we print isn't useful to a normal user. This dramatically reduces the amount of messages printed by OPAL in normal circumstances.

ISAv3 added the STOP instruction to act as a front end to the various power saving modes.

2016-09-27core/init: create the dt root in main_cpu_entryOliver O'Halloran1-2/+0

2016-09-27core/init: remove master_cpu parameterOliver O'Halloran1-9/+6
master_cpu is used to determine the ChipTOD master if no ChipTOD information is available in the HDAT. However, it is set to zero at every skiboot entry point (fdt_entry, the 0x180 FSP entry and opal_boot_trampoline) and is otherwise unused. This patch removes this passing around and uses the boot CPU PIR to find the ChipTOD master rather than zero.

2016-04-01hdata: Enable SPIRA-HVasant Hegde1-0/+48
Update the SPIRA-H pointer in the NACA so that the FSP can build and pass the SPIRA-S structure to OPAL instead of the legacy SPIRA. Older systems (which does not support SPIRA-H) ignores SPIRA-H pointer and continue to pass legacy SPIRA. "spira" is a global structure and referred everywhere inside hdata dir. Once we enable SPIRA-H we get data in SPIRA-S area, not in legacy spira. Hence fixup spira structure, so that we don't break building device tree.

2016-04-01hdata: Initialize SPIRA-H structureVasant Hegde1-0/+46
Previous patch reduced reserved space in spira structure. Now its safe to reduce the memory for spira section from 2K to 1K. Create separate memory section with 1K size for SPIRA-H.

On FSP based machine, FSP controls System Attention Indicator. This indicator detail (location code) is passed to OPAL via HDAT. OPAL can get/set this indicator via normal MBOX command. This patch takes care of parsing SLCA entry and populating device tree with SAI location code. Device Tree: We create '/ibm,opal/led' node which contains all location code LED information. 'led-types' property under each node tells LED type. For SAI indicator 'led-types' property will be 'attention'.

2014-08-01ATTN: Set up attention area to handle attentionAruna Balakrishnaiah1-0/+36
At present CPU control area ntuple in SPIRA structure is NULL. ATTN component in Service Processor side checks for this field and if its empty, it logs hardcoded SRC (0xBB821410) and generates SYSDUMP. So we have 1 SRC for all failure (assert call) from OPAL side. This makes difficult to debug the issue. Service processor provides attention area interface (FIPS PHyp Attentions spec), so that we can pass SRC and user data (error message) to service processor. This will helps us identify different failures in OPAL. This patch enables attention area and provides interface (update_sp_attn_area()) to add src and user data (error message) through assert macro. Attention SRC format: 1st byte - Opal src type 2-4 bytes - Holds the address of the assert function call Signed-off-by: Aruna Balakrishnaiah <aruna@linux.vnet.ibm.com> Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
