* gpu: nvgpu: Implement compbits mappingSami Kiminki2015-05-18
| | | | | | | | | | | | | | | | | | | | | | | | Implement NVGPU_AS_IOCTL_GET_BUFFER_COMPBITS_INFO for requesting info on compbits-mappable buffers; and NVGPU_AS_IOCTL_MAP_BUFFER_COMPBITS, which enables mapping compbits to the GPU address space of said buffers. This, subsequently, enables moving comptag swizzling from GPU to CDEH/CDEV formats to userspace. Compbits mapping is conservative and it may map more than what is strictly needed. This is because two reasons: 1) mapping must be done on small page alignment (4kB), and 2) GPU comptags are swizzled all around the aggregate cache line, which means that the whole cache line must be visible even if only some comptag lines are required from it. Cache line size is not necessarily a multiple of the small page size.
