This is an issue because a driver may have to maintain two copies of a texture if it batches all uploads together at the start of a frame. In the Vulkan backend, we do something similar to avoid breaking out of a render pass to copy a texture from the streaming buffer to the destination image. This was causing issues in the sms-bubbles fifolog, where an EFB copy to the same address of a previously-used texture caused the previous texture to be re-used again for a different image later on in the frame, causing the original contents to be discarded.

|

// If the same texture address is used several times during the same frame, assume the address is

// used

|
|
// 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
