Eu não entendo alguns argumentos para o comando xrandr

Question

Considerando esses argumentos:

--listproviders

Report information about the providers available.

--setprovideroutputsource provider source

Set source as the source of display output images for provider. This is only possible if source and provider have the Source Output and Sink Output capabilities, respectively. If source is 0x0, then provider is disconnected from its current output source.

--setprovideroffloadsink provider sink

Set provider as a render offload device for sink. This is only possible if provider and sink have the Source Offload and Sink Offload capabilities, respectively. If sink is 0x0, then provider is disconnected from its current render offload sink.

O que significa a documentação por "sink", "provider", "source" e "offload"?
