/*
|
|
* General notes on MMU parameters.
|
|
*
|
|
* Terminology:
|
|
* ASID = address-space ID (acts as an "extension" of virtual addresses)
|
|
* VPN = virtual page number
|
|
* PPN = physical page number
|
|
* CA = encoded cache attribute (access modes)
|
|
* TLB = translation look-aside buffer (term is stretched somewhat here)
|
|
* I = instruction (fetch accesses)
|
|
* D = data (load and store accesses)
|
|
* way = each TLB (ITLB and DTLB) consists of a number of "ways"
|
|
* that simultaneously match the virtual address of an access;
|
|
* a TLB successfully translates a virtual address if exactly
|
|
* one way matches the vaddr; if none match, it is a miss;
|
|
* if multiple match, one gets a "multihit" exception;
|
|
* each way can be independently configured in terms of number of
|
|
* entries, page sizes, which fields are writable or constant, etc.
|
|
* set = group of contiguous ways with exactly identical parameters
|
|
* ARF = auto-refill; hardware services a 1st-level miss by loading a PTE
|
|
* from the page table and storing it in one of the auto-refill ways;
|
|
* if this PTE load also misses, a miss exception is posted for s/w.
|
|
* min-wired = a "min-wired" way can be used to map a single (minimum-sized)
|
|
* page arbitrarily under program control; it has a single entry,
|
|
* is non-auto-refill (some other way(s) must be auto-refill),
|
|
* all its fields (VPN, PPN, ASID, CA) are all writable, and it
|
|
* supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
|
|
* restriction is that this be the only page size it supports).
|
|
*
|
|
* TLB way entries are virtually indexed.
|
|
* TLB ways that support multiple page sizes:
|
|
* - must have all writable VPN and PPN fields;
|
|
* - can only use one page size at any given time (eg. setup at startup),
|
|
* selected by the respective ITLBCFG or DTLBCFG special register,
|
|
* whose bits n*4+3 .. n*4 index the list of page sizes for way n
|
|
* (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
|
|
* this list may be sparse for auto-refill ways because auto-refill
|
|
* ways have independent lists of supported page sizes sharing a
|
|
* common encoding with PTE entries; the encoding is the index into
|
|
* this list; unsupported sizes for a given way are zero in the list;
|
|
* selecting unsupported sizes results in undefine hardware behaviour;
|
|
* - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).
