hdata: Fix DIMM size property

2018-04-23T05:02:43+00:00

Today we parse vpd blob to get DIMM size information. This is limited to FSP based system. HDAT provides DIMM size value. Lets use that to populate device tree. So that we can get size information on BMC based system as well. Signed-off-by: Vasant Hegde CC: Oliver O'Halloran Signed-off-by: Stewart Smith

hdata/spira: parse vpd to add part-number and serial-number to xscom@ node

2018-04-11T22:59:57+00:00

Expected by FWTS and associates our processor with the part/serial number, which is obviously a good thing for one's own sanity. Signed-off-by: Stewart Smith Reviewed-by: Vasant Hegde Signed-off-by: Stewart Smith

hdata/vpd: Fix DTC warnings

2018-01-15T04:38:55+00:00

All the nodes under the vpd heirachy have a unit address (their SLCA index) but no reg properties. Add them and their size/address cells to squash the warnings. Signed-off-by: Oliver O'Halloran Signed-off-by: Stewart Smith

lock: Add additional lock auditing code

2017-12-21T04:15:36+00:00

Keep track of lock owner name and replace lock_depth counter with a per-cpu list of locks held by the cpu. This allows us to print the actual locks held in case we hit the (in)famous message about opal_pollers being run with a lock held. It also allows us to warn (and drop them) if locks are still held when returning to the OS or completing a scheduled job.

hdata/tpmrel.c: add firmware event log info to the tpm node

2017-12-19T03:30:57+00:00

This parses the firmware event log information from the secureboot_tpm_info HDAT structure and add it to the tpm device tree node. There can be multiple secureboot_tpm_info entries with each entry corresponding to a master processor that has a tpm device, however, multiple tpm is not supported.

hdata: Add memory hierarchy under xscom node

2017-12-18T23:58:32+00:00

We have memory to chip mapping but doesn't have complete memory hierarchy. This patch adds memory hierarchy under xscom node. This is specific to P9 system as these hierarchy may change between processor generation. It uses memory controller ID details and populates nodes like: xscom@/mcbist@/mcs@/mca@/dimm@ Also this patch adds few properties under dimm node. Finally make sure xscom nodes created before calling memory_parse(). Signed-off-by: Vasant Hegde Signed-off-by: Stewart Smith

make check: Make valgrind optional

2017-12-18T23:58:32+00:00

To (slightly) lower the barrier for contributions, we can make valgrind optional with just a small amount of plumbing. This allows make check to run successfully without valgrind. Signed-off-by: Michael Ellerman Signed-off-by: Stewart Smith

hdata/vpd: Rework vpd node creation logic

2017-10-17T02:51:28+00:00

Presently we traverse SLCA structure to create various FRU nodes under /vpd node. We assumed that children are always contiguous. It happened to be contiguous in P8 and worked fine, but failed in P9 system. So it ended up populating duplicate node under wrong parent. Also failed to populate some of the nodes. Unfortunately there is no way to reach all the children of a given parent from parent node :-( Hence we have to rework vpd creation logic. This patch goes through all the SLCA entries serially and creates vpd node. Assumptions: - SLCA index is always serial (0..n) - When we traverse serially parent entry comes before child - Redundant resources are always consecutive - Populate node if SLCA has 'installed' and 'VPD collected' bit set CC: Ananth N Mavinakayanahalli Signed-off-by: Vasant Hegde Reviewed-by: Oliver O'Halloran Signed-off-by: Stewart Smith
