591209c7 - cxl/memdev: Replace ENXIO with EBUSY for inject poison limit reached

Sun, 07 Jul 2024 01:53:43 +0000

cxl/memdev: Replace ENXIO with EBUSY for inject poison limit reachedThe CXL driver provides a debugfs interface offering users theability to inject and clear poison to a memdev. Once a user hasinjected up to the devices limit further injection requests failwith ENXIO until a clear poison is issued.Users may not have device specs in hand or may want to intentionallyhit the limit and then clear. Replace the usual ENXIO return statuswith EBUSY so users can recognize this failure.Signed-off-by: Alison Schofield Tested-by: Xingtao Yao Reviewed-by: Dan Williams Reviewed-by: Davidlohr Bueso Link: https://patch.msgid.link/825bd4c67fb55a4373c4182d999ad49d4e6b4fe7.1720316188.git.alison.schofield@intel.comSigned-off-by: Dave Jiang List of files: /linux-6.15/Documentation/ABI/testing/debugfs-cxl

Documentation/ABI/testing/debugfs-cxl: Fix "Unexpected indentation"Stephen reported that an htmldocs build hit: Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation.It turns out that line was fine but the tool was unhappy about some linebreaks in the table of values to error types.It turns out that: make V=1 SPHINXDIRS="admin-guide" htmldocs...can not be used to get more info about what is behind a documentationbuild error. It was only pure luck that reflowing the text resulted inan error message that seemed a imply a problem later on with line breaksaround the table.Fixes: 8039804cfa73 ("cxl/core: Add CXL EINJ debugfs files")Cc: Jonathan Corbet Reported-by: Stephen Rothwell Closes: http://lore.kernel.org/r/20240314141313.7ba04aff@canb.auug.org.auCc: Ben Cheatham Signed-off-by: Dan Williams List of files: /linux-6.15/Documentation/ABI/testing/debugfs-cxl

8039804c - cxl/core: Add CXL EINJ debugfs files

Mon, 11 Mar 2024 14:25:07 +0000

cxl/core: Add CXL EINJ debugfs filesExport CXL helper functions in einj-cxl.c for getting/injectingavailable CXL protocol error types to sysfs under kernel/debug/cxl.The kernel/debug/cxl/einj_types file will print the available CXLprotocol errors in the same format as the available_error_typesfile provided by the einj module. Thekernel/debug/cxl/$dport_dev/einj_inject file is functionally the sameas the error_type and error_inject files provided by the EINJ module,i.e.: writing an error type into $dport_dev/einj_inject will injectsaid error type into the CXL dport represented by $dport_dev.Reviewed-by: Jonathan Cameron Signed-off-by: Ben Cheatham Link: https://lore.kernel.org/r/20240311142508.31717-4-Benjamin.Cheatham@amd.comSigned-off-by: Dan Williams List of files: /linux-6.15/Documentation/ABI/testing/debugfs-cxl
