Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3dwddm1_3ddi_resizetilepool)

PFND3DWDDM1_3DDI_RESIZETILEPOOL callback function

Description

Resizes a tile pool.

Parameters

`hDevice`

A handle to the display device (graphics context).

`hTilePool`

A handle to the tile pool to resize.

`NewSizeInBytes`

The new size, in bytes, of the tile pool. The size must be a multiple of 64 KB or zero.

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code, setting S_OK if successful; otherwise, returning one of the following:

Return code	Description
E_INVALIDARG	The new tile pool size isn't a multiple of 64 KB or zero. The existing tile pool remains unchanged, which includes existing mappings.
E_OUTOFMEMORY	The driver had to allocate space for new page table mappings but ran out of memory. The existing tile pool remains unchanged, which includes existing mappings.

The Direct3D runtime performs minimal validation of parameters, but it will fail the call if the new tile pool size isn't a multiple of the tile size, or zero.
