2016-03-14drm/nouveau/fifo/gk110: expose KeplerChannelGpfifoBBen Skeggs9-2/+89
This class supports a WFI method (0x0078) that's not present on the KeplerChannelGpfifoA class. The binary driver exposes both classes on these GPUs for some reason, though there doesn't appear to be any difference in the setup that's done for each (ie. even if you allocate GpfifoA, the WFI method will still work). We shall just expose GpfifoB, as I don't see a good reason to report the presence of both. Signed-off-by: Ben Skeggs <[email protected]>

2016-03-14drm/nouveau/gr/fuc: Store $r0 in interrupt handlerRoy Spliet14-932/+936
It's supposed to always be 0, but at least nv_iowr() temporarily violates this. Since the ih touches $r0, it should be stored. Signed-off-by: Roy Spliet <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>

2016-03-14drm/nouveau/core: use vzalloc for allocating ramhtIlia Mirkin1-3/+3
Most calls to nvkm_ramht_new use 0x8000 as the size. This results in a fairly sizeable chunk of memory to be allocated, which may not be available with kzalloc. Since this is done fairly rarely (once per channel), use vzalloc instead. Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2016-03-14drm/nouveau/fifo/gk104: kick channel upon removalAlexandre Courbot1-0/+1
A channel may still be processed by the PBDMA even after removal, unless it is properly kicked. Some chips are more sensible to this than others, with GM20B triggering the issue very easily (the PBDMA will try to fetch methods from the previously-removed channel after a new one is added). Make sure this cannot happen by kicking the channel right after it is disabled, and before the new runlist is submitted.

2016-03-14drm/nouveau/instmem/gk20a: add write barrier when releasing DMA objectAlexandre Courbot1-0/+2
When using the DMA-API for instmem, we may obtain a write-combined mapping. For such cases, add a write barrier in gk20a_instobj_release_dma() to make sure that all writes have reached memory at this time.

2016-03-14drm/nouveau/device/pci: set as non-CPU-coherent on ARM64Alexandre Courbot1-1/+1

2016-03-14drm/nouveau/hwmon: fix crash on non-PCI platformsAlexandre Courbot1-1/+1
Registration of the hwmon device will fail on non-PCI systems since dev->pdev is NULL in that case.

2016-03-14drm/nouveau/bo: consider DMA buffers on x86 onlyAlexandre Courbot1-2/+2
The DMA API has different semantics on different architectures. Currently on arm64, it can only provide memory from a small pool which dries up quickly if we attempt to allocate big buffers from it. Do not consider that option when running on non-x86, since regular TTM buffers are the (current) best-fit for ARM platforms.

2016-03-14drm/nouveau/ltc/gf100: use more reasonable timeout valueAlexandre Courbot1-6/+2
LTC operations timeout was set to 2ms, which may be too low for devices that run at very low clocks (e.g. GM20B) and trigger timeout messages. Set the timeout to the default 2s. Also remove the redundant error messages since nvkm_wait_msec() will already display a warning. Signed-off-by: Alexandre Courbot <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>

Fix the channel id bit mask in FIFO schedule timeout error handling. FIFO_ENGINE_STATUS_NEXT_ID is bit 27:16 thus 0x0fff0000. FIFO_ENGINE_STATUS_ID is bit 11:0 thus 0x00000fff.

2016-03-14drm/nouveau/instmem/gk20a: set DMA mask earlyAlexandre Courbot1-0/+9
DMA mask is typically set in nouveau_ttm_init(), but this function is called late during initialization and GK20A's instmem will have called DMA functions before this happens. Having a wrongly set DMA mask can result in the use of unneeded bounce buffers. Set it early to avoid this.
