From: Alison Schofield <alison.schofi...@intel.com> Changes since v9: - Replace the multi-use 'name' var, with multiple descriptive flavors: memdev_name, region_name, decoder_name (DaveJ) - Use a static string table for poison source lookup (DaveJ) - Rebased on latest pending Link to v9: https://lore.kernel.org/r/cover.1709253898.git.alison.schofi...@intel.com/
Add the option to add a memory devices poison list to the cxl-list json output. Offer the option by memdev and by region. Sample usage: # cxl list -m mem1 --media-errors [ { "memdev":"mem1", "pmem_size":1073741824, "ram_size":1073741824, "serial":1, "numa_node":1, "host":"cxl_mem.1", "media_errors":[ { "dpa":0, "length":64, "source":"Internal" }, { "decoder":"decoder10.0", "hpa":1035355557888, "dpa":1073741824, "length":64, "source":"External" }, { "decoder":"decoder10.0", "hpa":1035355566080, "dpa":1073745920, "length":64, "source":"Injected" } ] } ] # cxl list -r region5 --media-errors [ { "region":"region5", "resource":1035355553792, "size":2147483648, "type":"pmem", "interleave_ways":2, "interleave_granularity":4096, "decode_state":"commit", "media_errors":[ { "decoder":"decoder10.0", "hpa":1035355557888, "dpa":1073741824, "length":64, "source":"External" }, { "decoder":"decoder8.1", "hpa":1035355566080, "dpa":1073745920, "length":64, "source":"Internal" } ] } ] Alison Schofield (7): libcxl: add interfaces for GET_POISON_LIST mailbox commands cxl: add an optional pid check to event parsing cxl/event_trace: add a private context for private parsers cxl/event_trace: add helpers to retrieve tep fields by type cxl/list: collect and parse media_error records cxl/list: add --media-errors option to cxl list cxl/test: add cxl-poison.sh unit test Documentation/cxl/cxl-list.txt | 79 +++++++++- cxl/event_trace.c | 82 ++++++++++- cxl/event_trace.h | 14 +- cxl/filter.h | 3 + cxl/json.c | 257 +++++++++++++++++++++++++++++++++ cxl/lib/libcxl.c | 47 ++++++ cxl/lib/libcxl.sym | 2 + cxl/libcxl.h | 2 + cxl/list.c | 3 + test/cxl-poison.sh | 137 ++++++++++++++++++ test/meson.build | 2 + 11 files changed, 624 insertions(+), 4 deletions(-) create mode 100644 test/cxl-poison.sh base-commit: e0d0680bd3e554bd5f211e989480c5a13a023b2d -- 2.37.3
