* drm/nouveau: Split nouveau_fence_syncLauri Peltonen2016-01-156-59/+54
| | | | | | | | | | | | | | | | Split nouveau_fence_sync to two functions: * nouveau_fence_sync, which only adds a fence wait to the channel command stream, and * nouveau_bo_sync, which gets the fences from the reservation object and passes them to nouveau_fence_sync. This factorizes the code in the new nouveau_fence_sync() which was present twice otherwise.

* ltc/gm107: wait on relevant bit in gm107_ltc_cbc_waitAlexandre Courbot2016-01-151-4/+2
| | | | | | | | | | | | | | | Patch "ltc/gm107: use nvkm_mask to set cbc_ctrl1" sets the 3rd bit of the CTRL1 register instead of writing it entirely in gm107_ltc_cbc_clear(). As a counterpart, gm107_ltc_cbc_wait() must also be modified to wait on that single bit only, otherwise a timeout may occur if some other bit of that register is set. This happened at least on GM206 when running glmark2-drm. While we are at it, use the more compact nvkm_wait_msec() to wait for the bit to clear.

* instmem/gk20a: use DMA API CPU mappingAlexandre Courbot2016-01-112-98/+62
| | | | | | | | | | | | | | | | | | | | | Commit 69c4938249fb ("drm/nouveau/instmem/gk20a: use direct CPU access") tried to be smart while using the DMA-API by managing the CPU mappings of buffers allocated with the DMA-API by itself. In doing so, it relied on dma_to_phys() which is an architecture-private function not available everywhere. This broke the build on several architectures. Since there is no reliable and portable way to obtain the physical address of a DMA-API buffer, stop trying to be smart and just use the CPU mapping that the DMA-API can provide. This means that buffers will be CPU-mapped for all their life as opposed to when we need them, but anyway using the DMA-API here is a fallback for when no IOMMU is available so we should not expect optimal behavior. This makes the IOMMU and DMA-API implementations of instmem diverge enough that we should maybe put them into separate files...

* instmem/gk20a: fix race conditionsAlexandre Courbot2016-01-111-29/+37
| | | | | | | | | | | | | | | | The LRU list used for recycling CPU mappings was handling concurrency very poorly. For instance, if an instobj was acquired twice before being released once, it would end up into the LRU list even though there is still a client accessing it. This patch fixes this by properly counting how many clients are currently using a given instobj. While at it, we also raise errors when inconsistencies are detected, and factorize some code.

This patch tests for either TEGRA_124_SOC or TEGRA_132_SOC for the firmwares related to the Tegra K1 generation. v2: move the MODULE_FIRMWARE to the nvidia_platform.c file.
