/*
|
|
* Cache operations:
|
|
*
|
|
* We define the following primitives:
|
|
*
|
|
* icache_sync_all Synchronize I-cache
|
|
* icache_sync_range Synchronize I-cache range
|
|
*
|
|
* dcache_wbinv_all Write-back and Invalidate D-cache
|
|
* dcache_wbinv_range Write-back and Invalidate D-cache range
|
|
* dcache_inv_range Invalidate D-cache range
|
|
* dcache_wb_range Write-back D-cache range
|
|
*
|
|
* idcache_wbinv_all Write-back and Invalidate D-cache,
|
|
* Invalidate I-cache
|
|
* idcache_wbinv_range Write-back and Invalidate D-cache,
|
|
* Invalidate I-cache range
|
|
*
|
|
* Note that the ARM term for "write-back" is "clean". We use
|
|
* the term "write-back" since it's a more common way to describe
|
|
* the operation.
|
|
*
|
|
* There are some rules that must be followed:
|
|
*
|
|
* ID-cache Invalidate All:
|
|
* Unlike other functions, this one must never write back.
|
|
* It is used to intialize the MMU when it is in an unknown
|
|
* state (such as when it may have lines tagged as valid
|
|
* that belong to a previous set of mappings).
|
|
*
|
|
* I-cache Synch (all or range):
|
|
* The goal is to synchronize the instruction stream,
|
|
* so you may beed to write-back dirty D-cache blocks
|
|
* first. If a range is requested, and you can't
|
|
* synchronize just a range, you have to hit the whole
|
|
* thing.
|
|
*
|
|
* D-cache Write-Back and Invalidate range:
|
|
* If you can't WB-Inv a range, you must WB-Inv the
|
|
* entire D-cache.
|
|
*
|
|
* D-cache Invalidate:
|
|
* If you can't Inv the D-cache, you must Write-Back
|
|
* and Invalidate. Code that uses this operation
|
|
* MUST NOT assume that the D-cache will not be written
|
|
* back to memory.
|
|
*
|
|
* D-cache Write-Back:
|
|
* If you can't Write-back without doing an Inv,
|
|
* that's fine. Then treat this as a WB-Inv.
|
|
* Skipping the invalidate is merely an optimization.
|
|
*
|
|
* All operations:
|
|
* Valid virtual addresses must be passed to each
|
|
* cache operation.
