Douglas Thompson42a8e392007-07-19 01:50:10 -0700104 * The following are the structures to provide for a generic
Douglas Thompsone27e3da2007-07-19 01:49:36 -0700105 * or abstract 'edac_device'. This set of structures and the
106 * code that implements the APIs for the same, provide for
107 * registering EDAC type devices which are NOT standard memory.
108 *
109 * CPU caches (L1 and L2)
110 * DMA engines
111 * Core CPU swithces
112 * Fabric switch units
113 * PCIe interface controllers
114 * other EDAC/ECC type devices that can be monitored for
115 * errors, etc.
116 *
117 * It allows for a 2 level set of hiearchry. For example:
118 *
119 * cache could be composed of L1, L2 and L3 levels of cache.
120 * Each CPU core would have its own L1 cache, while sharing
121 * L2 and maybe L3 caches.
122 *
123 * View them arranged, via the sysfs presentation:
124 * /sys/devices/system/edac/..
125 *
126 * mc/ <existing memory device directory>
127 * cpu/cpu0/.. <L1 and L2 block directory>
128 * /L1-cache/ce_count
129 * /ue_count
130 * /L2-cache/ce_count
131 * /ue_count
132 * cpu/cpu1/.. <L1 and L2 block directory>
133 * /L1-cache/ce_count
134 * /ue_count
135 * /L2-cache/ce_count
136 * /ue_count
137 * ...
138 *
139 * the L1 and L2 directories would be "edac_device_block's"
