Member Enumeration Documentation

◆ Reason

Enumerator
Unknown 
FromStorageToSysRam 

OnStorage -> OnSystemRam.

FromSysRamToStorage 

OnSystemRam -> OnStorage.

GainedResidency 

OnStorage -> Resident OnSystemRam -> Resident See ReadyForRendering.

LostResidency 

Resident -> OnStorage Resident -> OnSystemRam.

PoolTextureSlotChanged 
ResidentToSysRamSync 

Only called while TextureGpu is still Resident, and strategy is AlwaysKeepSystemRamCopy.

This listener happens when something was done to the TextureGpu that modifies its contents in the GPU, and were thus forced to sync those values back to SystemRam. This listener calls tells that sync is over.

MetadataCacheOutOfDate 

The Metadata cache was out of date and we had to do a ping-pong.

Expect this to be followed by at least LostResidency and GainedResidency calls

This is very important, because if you were expecting certain sequence of calls (e.g. you were expecting a LostResidency soon to arrive), expect that to be changed.

See TextureGpuManager for details about the metadata cache.

ExceptionThrown 

Called when the worker thread caught an exception.

This exception has already been logged, and the texture resumed loading normally with a white 2x2 RGBA8 fallback.

This listener will get called from the main thread.

The texture may still have pending residency transitions (e.g. it may still be loading the 2x2 fallback)

Cast Exception e = reinterpret_cast<Exception>( extraData ); to know more info

FsaaSettingAlteredByApi 

Requested FSAA (MSAA / CSAA / EQAA / etc) is not supported by the API, and thus the setting had to be downgraded.

Note this may happen on device lost, and a new GPU became in use; thus it's possible for a TextureGpu to initially support certain FSAA but later change.

ReadyForRendering 

This Reason is called when TextureGpu::notifyDataIsReady is called.

This normally means worker thread is done loading texture from file and uploading it to GPU; and can now be used for rendering. It does NOT mean that Ogre has finished issueing rendering commands to a RenderTexture and is now ready to be presented to the monitor.

◆ _placeBarriersAndEmulateUavExecution()

virtual void Ogre::CompositorPassUav::_placeBarriersAndEmulateUavExecution ( BoundUav  boundUavs[64],
ResourceAccessMap uavsAccess,
ResourceLayoutMap resourcesLayout 
)
virtual

Emulates the execution of a UAV to understand memory dependencies, and adds a memory barrier / resource transition if we need to.

Remarks
Note that an UAV->UAV resource transition is just a memory barrier.
Parameters
boundUavs[in/out] An array of the currently bound UAVs by slot. The derived class CompositorPassUav will write to them as part of the emulation. The base implementation reads from this value.
uavsAccess[in/out] A map with the last access flag used for each RenderTarget. We need it to identify RaR situations, which are the only ones that don't need a barrier (and also WaW hazards, when explicitly allowed by the pass). Note: We will set the access to ResourceAccess::Undefined to signal other passes that the UAV hazard already has a barrier (just in case there was one already created).
resourcesLayout[in/out] A map with the current layout of every RenderTarget used so far. Needed to identify if we need to change the resource layout to an UAV.

Reimplemented from Ogre::CompositorPass.

◆ notifyTextureChanged()

virtual void Ogre::CompositorPassUav::notifyTextureChanged ( TextureGpu texture,

Called when a TextureGpu changed in a way that affects how it is displayed:

  1. TextureGpu::notifyDataIsReady got called (texture is ready to be displayed)
  2. Texture changed residency status.
  3. Texture is being deleted. It won't be a valid pointer after this call.

Implements Ogre::TextureGpuListener.
