These devices + * commonly output 4 and 8 bits each. Grouping several + * of these in parallel provides 64 bits which is common + * for a memory stick. + * + * Memory Stick: A printed circuit board that aggregates multiple + * memory devices in parallel. This is the atomic + * memory component that is purchaseable by Joe consumer + * and loaded into a memory socket. + * + * Socket: A physical connector on the motherboard that accepts + * a single memory stick. + * + * Channel: Set of memory devices on a memory stick that must be + * grouped in parallel with one or more additional + * channels from other memory sticks. This parallel + * grouping of the output from multiple channels are + * necessary for the smallest granularity of memory access. + * Some memory controllers are capable of single channel - + * which means that memory sticks can be loaded + * individually. Other memory controllers are only + * capable of dual channel - which means that memory + * sticks must be loaded as pairs (see "socket set"). + * + * Chip-select row: All of the memory devices that are selected together. + * for a single, minimum grain of memory access. + * This selects all of the parallel memory devices across + * all of the parallel channels. Common chip-select rows + * for single channel are 64 bits, for dual channel 128 + * bits. + * + * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory. + * Motherboards commonly drive two chip-select pins to + * a memory stick. A single-ranked stick, will occupy + * only one of those rows. The other will be unused. + * + * Double-Ranked stick: A double-ranked stick has two chip-select rows which + * access different sets of memory devices. The two + * rows cannot be accessed concurrently. + * + * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick. + * A double-sided stick has two chip-select rows which + * access different sets of memory devices. The two + * rows cannot be accessed concurrently. "Double-sided" + * is irrespective of the memory devices being mounted + * on both sides of the memory stick. + * + * Socket set: All of the memory sticks that are required for + * a single memory access or all of the memory sticks + * spanned by a chip-select row. A single socket set + * has two chip-select rows and if double-sided sticks + * are used these will occupy those chip-select rows. + * + * Bank: This term is avoided because it is unclear when + * needing to distinguish between chip-select rows and + * socket sets. + * + * Controller pages: + * + * Physical pages: + * + * Virtual pages: + * + * + * STRUCTURE ORGANIZATION AND CHOICES + * + * + * + * PS - I enjoyed writing all that about as much as you enjoyed reading it. + */ + +struct channel_info { + int chan_idx; /* channel index */ + u32 ce_count; /* Correctable Errors for this CHANNEL */ + char label[EDAC_MC_LABEL_LEN + 1]; /* DIMM label on motherboard */ + struct csrow_info *csrow; /* the parent */ +}; + +struct csrow_info { + unsigned long first_page; /* first page number in dimm */ + unsigned long last_page; /* last page number in dimm */ + unsigned long page_mask; /* used for interleaving - + * 0UL for non intlv + */ + u32 nr_pages; /* number of pages in csrow */ + u32 grain; /* granularity of reported error in bytes */ + int csrow_idx; /* the chip-select row */ + enum dev_type dtype; /* memory device type */ + u32 ue_count; /* Uncorrectable Errors for this csrow */ + u32 ce_count; /* Correctable Errors for this csrow */ + enum mem_type mtype; /* memory csrow type */ + enum edac_type edac_mode; /* EDAC mode for this csrow */ + struct mem_ctl_info *mci; /* the parent */ + + struct kobject kobj; /* sysfs kobject for this csrow */ + + /* channel information for this csrow */ + u32 nr_channels; + struct channel_info *channels; +}; + +struct mcidev_sysfs_group { + const char *name; /* group name */ + const struct mcidev_sysfs_attribute *mcidev_attr; /* group attributes */ +}; + +struct mcidev_sysfs_group_kobj { + struct list_head list; /* list for all instances within a mc */ + + struct kobject kobj; /* kobj for the group */ + + const struct mcidev_sysfs_group *grp; /* group description table */ + struct mem_ctl_info *mci; /* the parent */ +}; + +/* mcidev_sysfs_attribute structure + * used for driver sysfs attributes and in mem_ctl_info + * sysfs top level entries + */ +struct mcidev_sysfs_attribute { + /* It should use either attr or grp */ + struct attribute attr; + const struct mcidev_sysfs_group *grp; /* Points to a group of attributes */ + + /* Ops for show/store values at the attribute - not used on group */ + ssize_t (*show)(struct mem_ctl_info *,char *); + ssize_t (*store)(struct mem_ctl_info *, const char *,size_t); +}; + +/* MEMORY controller information structure + */ +struct mem_ctl_info { + struct list_head link; /* for global list of mem_ctl_info structs */ + + struct module *owner; /* Module owner of this control struct */ + + unsigned long mtype_cap; /* memory types supported by mc */ + unsigned long edac_ctl_cap; /* Mem controller EDAC capabilities */ + unsigned long edac_cap; /* configuration capabilities - this is + * closely related to edac_ctl_cap.
