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
