Patch 1, 2: Cleanups to the code. No functional change Patch 3: Modifying flags attribute to accept string arguments and have do_inject() recognize these changes before injecting a 'sw' or 'hw' error Patch 4: Extend flags attribute to accept values of 'dfr', 'thr'. These values will be used to trigger deferred error/threshold error apic interrupts respectively Patch 5: Include permissions for each file within struct dfs_node dfs_fls[] Patch 6: Add README file that describes the attributes Patch 7: Factor out number of nodes calculation from amd_get_topology(). No functional change. Patch 8: Provide accessor function to obtain the number of nodes per processor Patch 9: Modify injection mechanism for bank 4 errors. Since they are typically logged or reported only on NBC, we make sure that we inject on the correct core here.
Changes in V2: (per Boris) - Remove arbitrary definition of MAX_FLAG_OPT_SIZE and define it to sizeof the flag option we are introducing in the patch (Patch 3) - Increase it later as needed (Patch 4) - Simplify string comparison loop in __set_inj() - Move return value assignment in flags_write() to after initial condition - Remove hardcoded numbers used to inject deferred/threshold interrupts and use respective macros instead - Use switch-case to decide between injecting apic interrupts and #MC - Add permissions to dfs_fls[] array in a separate patch (Patch 5) and README file in the following patch (Patch 6) - Remove CONFIG_X86_HT ifdefs and factor out number of nodes calculation - Provide accessor function in amd.c
Aravind Gopalakrishnan (9): edac, mce_amd_inj: Use MCE_INJECT_GET for bank edac, mce_amd_inj: Rework sanity check for inj_bank_set edac, mce_amd_inj: Modify flags attrigute to use string arguments edac, mce_amd_inj: Add capability to trigger apic interrupts edac, mce_amd_inj: Add individual permissions field for dfs_node edac, mce_amd_inj: Add README file x86, amd: Factor out number of nodes calculation x86, amd: Provide accessor for number of nodes edac, mce_amd_inj: Inject errors on NBC for bank 4 errors
