Specify TTM_PL_FLAG_UNCACHED when allocating GPFIFOs and fences to allow them to be safely accessed by the kernel without being synced on non-coherent architectures. Signed-off-by:

Allow nouveau_bo_new() to recognize the TTM_PL_FLAG_UNCACHED flag, which means that we want the allocated BO to be perfectly coherent between the CPU and GPU. This is useful on non-coherent architectures for which we do not want to manually sync some rarely-accessed buffers: typically, fences and pushbuffers. A TTM BO allocated with the TTM_PL_FLAG_UNCACHED on a non-coherent architecture will be populated using the DMA API, and accesses to it performed using the coherent mapping performed by dma_alloc_coherent().

Add a function allowing us to know whether a device is CPU-coherent, i.e. accesses performed by the CPU on GPU-mapped buffers will be immediately visible on the GPU side and vice-versa. For now, a device is considered to be coherent if it uses the PCI bus on a non-ARM architecture. Signed-off-by:

Pinned BOs are supposed to remain in their current location until unpinned. Display a warning for the supposedly-erroneous case where we are trying to move such objects. Signed-off-by:

Probably missing something here, doesn't make a lot of sense to write or+link data into a register whose offset is calculated by the same or+link info.. This is the all I've witnessed the binary driver and vbios doing so far, so it'll do. Signed-off-by: -

The binary driver has been doing this since GF119, and we've somehow gotten away with it. But, TMDS that hasn't been initialised already by the x86 vbios code is distorted without it on GM204. Signed-off-by: -

Logging at trace level, rather than as en error, as it seems conceivable that failure could be normal under certain circumstances (new bios, older sink that doesn't support a particular DPCD address) Signed-off-by: -

Starting from GM204, certain registers are no longer accessible by the host (or unsigned PMU firmware). This commit implements devinit on PMU, using a signed microcode image, and devinit data, from the VBIOS. Signed-off-by: -
