// when a texture changes, the old version of the texture is unlikely to be used again. If there were
|

// new cache entries created for normal texture updates, there would be a slowdown due to a huge amount
|
|
// of unused cache entries. Also thanks to texture pooling, overwriting an existing cache entry is
|
|
// faster than creating a new one from scratch.
|

|

// this case, it would be constantly overwritten, and effectively there wouldn't be any caching for
|
|
// those textures. Examples for this are Metroid Prime and Castlevania 3. Metroid Prime has multiple

// sets of fonts on each other stored in a single texture and uses the palette to make different
|
|
// characters visible or invisible. In Castlevania 3 some textures are used for 2 different things or
|
|
// at least in 2 different ways(size 1024x1024 vs 1024x256).
|

//
|

// To determine whether to use multiple cache entries or a single entry, use the following heuristic:
|
|
// If the same texture address is used several times during the same frame, assume the address is used
|
|
// for different purposes and allow creating an additional cache entry. If there's at least one entry
|
|
// that hasn't been used for the same frame, then overwrite it, in order to keep the cache as small as
|
|
// possible. If the current texture is found in the cache, use that entry.

|
|
//
|

// - EFB to RAM:
|
|
// Encodes the requested EFB data at its native resolution to the emulated RAM using shaders.
|
|
// Load() decodes the data from there again (using TextureDecoder) if the EFB copy is being used as a texture again.
|
|
// Advantage: CPU can read data from the EFB copy and we don't lose any important updates to the texture
|
|
// Disadvantage: Encoding+decoding steps often are redundant because only some games read or modify EFB copies before using them as textures.
|
|
//
|
|
// - EFB to texture:
|
|
// Copies the requested EFB data to a texture object in VRAM, performing any color conversion using shaders.
|
|
// Advantage: Works for many games, since in most cases EFB copies aren't read or modified at all before being used as a texture again.
|
|
// Since we don't do any further encoding or decoding here, this method is much faster.
|
|
// It also allows enhancing the visual quality by doing scaled EFB copies.
|
|
//
|
|
// - Hybrid EFB copies:
|
|
// 1a) Whenever this function gets called, encode the requested EFB data to RAM (like EFB to RAM)
|
|
// 1b) Set type to TCET_EC_DYNAMIC for all texture cache entries in the destination address range.
|
|
// If EFB copy caching is enabled, further checks will (try to) prevent redundant EFB copies.
|
|
// 2) Check if a texture cache entry for the specified dstAddr already exists (i.e. if an EFB copy was triggered to that address before):
|
|
// 2a) Entry doesn't exist:
|
|
// - Also copy the requested EFB data to a texture object in VRAM (like EFB to texture)
|
|
// - Create a texture cache entry for the target (type = TCET_EC_VRAM)
|
|
// - Store a hash of the encoded RAM data in the texcache entry.
|
|
// 2b) Entry exists AND type is TCET_EC_VRAM:
|
|
// - Like case 2a, but reuse the old texcache entry instead of creating a new one.
|
|
// 2c) Entry exists AND type is TCET_EC_DYNAMIC:
|
|
// - Only encode the texture to RAM (like EFB to RAM) and store a hash of the encoded data in the existing texcache entry.
|
|
// - Do NOT copy the requested EFB data to a VRAM object. Reason: the texture is dynamic, i.e. the CPU is modifying it. Storing a VRAM copy is useless, because we'd always end up deleting it and reloading the data from RAM anyway.
|
|
// 3) If the EFB copy gets used as a texture, compare the source RAM hash with the hash you stored when encoding the EFB data to RAM.
|
|
// 3a) If the two hashes match AND type is TCET_EC_VRAM, reuse the VRAM copy you created
|
|
// 3b) If the two hashes differ AND type is TCET_EC_VRAM, screw your existing VRAM copy. Set type to TCET_EC_DYNAMIC.
|
|
// Redecode the source RAM data to a VRAM object. The entry basically behaves like a normal texture now.
|
|
// 3c) If type is TCET_EC_DYNAMIC, treat the EFB copy like a normal texture.
|
|
// Advantage: Non-dynamic EFB copies can be visually enhanced like with EFB to texture.
|
|
// Compatibility is as good as EFB to RAM.
|
|
// Disadvantage: Slower than EFB to texture and often even slower than EFB to RAM.
|
|
// EFB copy cache depends on accurate texture hashing being enabled. However, with accurate hashing you end up being as slow as without a copy cache anyway.
|
|
//
|
|
// Disadvantage of all methods: Calling this function requires the GPU to perform a pipeline flush which stalls any further CPU processing.
|
|
//
|
|
// For historical reasons, Dolphin doesn't actually implement "pure" EFB to RAM emulation, but only EFB to texture and hybrid EFB copies.
