45e9809aff7304721fddb95654901b32195c9c7avboxsync DIX will fill everything out in the context except the driver_priv.
45e9809aff7304721fddb95654901b32195c9c7avboxsync The port_priv holds the private data specified for the port when
45e9809aff7304721fddb95654901b32195c9c7avboxsync Xv was initialized by the driver.
45e9809aff7304721fddb95654901b32195c9c7avboxsync The driver may store whatever it wants in driver_priv and edit
45e9809aff7304721fddb95654901b32195c9c7avboxsync the width, height and flags. If the driver wants to return something
45e9809aff7304721fddb95654901b32195c9c7avboxsync to the client it can allocate space in priv and specify the number
45e9809aff7304721fddb95654901b32195c9c7avboxsync of 32 bit words in num_priv. This must be dynamically allocated
45e9809aff7304721fddb95654901b32195c9c7avboxsync space because DIX will free it after it passes it to the client.

45e9809aff7304721fddb95654901b32195c9c7avboxsync DIX will fill everything out in the surface except the driver_priv.
45e9809aff7304721fddb95654901b32195c9c7avboxsync The driver may store whatever it wants in driver_priv. The driver
45e9809aff7304721fddb95654901b32195c9c7avboxsync may pass data back to the client in the same manner as the
45e9809aff7304721fddb95654901b32195c9c7avboxsync xf86XvMCCreateContextProc.

45e9809aff7304721fddb95654901b32195c9c7avboxsync DIX will fill everything out in the subpicture except the driver_priv,
45e9809aff7304721fddb95654901b32195c9c7avboxsync num_palette_entries, entry_bytes and component_order. The driver may
45e9809aff7304721fddb95654901b32195c9c7avboxsync store whatever it wants in driver_priv and edit the width and height.
45e9809aff7304721fddb95654901b32195c9c7avboxsync If it is a paletted subpicture the driver needs to fill out the
45e9809aff7304721fddb95654901b32195c9c7avboxsync num_palette_entries, entry_bytes and component_order. These are
45e9809aff7304721fddb95654901b32195c9c7avboxsync not communicated to the client until the time the surface is
45e9809aff7304721fddb95654901b32195c9c7avboxsync The driver may pass data back to the client in the same manner as the
