- gk20a iommu support - gm107 graphics support without needing proprietary ucode - various random fixes - more gm20x bring-up, fifo/ce are ok, gr is mostly complete with the exception of ctxsw ucode.. nvidia aren't playing nice yet so there's not much more that can be done at this point... I spent a lot of time trying to find a viable way of doing gr ctxsw without signed firmware, but the "security" restrictions on the fecs/gpccs falcons are excessive and go beyond what'd be necessary to protect the host from malicious firmware. This newer nvidia hw is VERY open-source unfriendly. I have some experimental host-based ctxsw work that could be a viable (albeit unsatisfactory and slow) workaround in the meantime, but it needs some more work and i'd like to get the 3d driver working properly before i commit to pushing it. * 'linux-4.1' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (40 commits) drm/nouveau/bios: fix fetching from acpi on certain systems drm/nouveau/gr/gm206: initial init+ctx code drm/nouveau/ce/gm206: enable support via gm204 code drm/nouveau/fifo/gm206: enable support via gm204 code drm/nouveau/gr/gm204: initial init+ctx code drm/nouveau: support for buffer moves via MaxwellDmaCopyA drm/nouveau/ce/gm204: initial support drm/nouveau: add support for gm20x fifo channels drm/nouveau/fifo/gm204: initial support drm/nouveau/gr/gk104-: prevent reading non-existent regs in intr handler drm/nouveau/gr/gm107: very slightly demagic part of attrib cb setup drm/nouveau/gr/gk104-: correct crop/zrop num_active_fbps setting drm/nouveau/gr/gf100-: add symbolic names for classes drm/nouveau/gr/gm107: support tpc "strand" ctxsw in gpccs ucode drm/nouveau/gr/gf100-: support mmio access with gpc offset from gpccs ucode drm/nouveau/gr: fix engine name, cosmetic search+replace mistake drm/nouveau/pmu/gk20a: add some missing statics drm/nouveau/platform: fix probe error path drm/nouveau/platform: release IOMMU's mm upon exit drm/nouveau/gr/gk104-gk20a: call pmu to disable any power-gating before ctor() ...

nvbios_extend() returns 1 to indicate "extended the array" and 0 to indicate the array is already big enough. This is used by the core shadowing code to prevent re-fetching chunks of the image that have already been shadowed. The ACPI fetching code may possibly need to extend this further due to requiring fetches to happen in 4KiB chunks. Under certain circumstances (that happen if the total image size is a multiple of 4KiB), the memory allocated to store the shadow will already be big enough, causing the ACPI code's nvbios_extend() call to return 0, which is misinterpreted as a failure. The fix is simple, accept >= 0 as a successful condition here. The core will have already made sure that we're not re-fetching data we already have.

Uncertain whether the GPC pack change is due to a newer driver version, or a legitimate difference from GM204. My GM204 has broken vram, so can't currently try a newer binary driver on it to confirm. Signed-off-by: -

A "return 0" found its way in the middle of the error path of nouveau_platform_probe(), remove it as it will make the kernel crash if we try to unload the module afterwards. While we are at it, also remove the IOMMU domain if it has been created, as we should. Signed-off-by:

If a memory allocation fails when using the DMA allocator, gk20a_instobj_dtor_dma() will be called on the failed instmem object. At this time, node->handle might not be NULL despite the call to dma_alloc_attrs() having failed. node->cpuaddr is the right member to check for such a failure, so use it instead. Reported-by:

User-space use mappable BOs notably for fences, and expects that a value update by the GPU will be immediatly visible through the user-space mapping. ARM has a property that may prevent this from happening though: memory can be mapped multiple times only if the different mappings share the same caching properties. However all the lowmem memory is already identity-mapped into the kernel with cache enabled, so when user-space requests an uncached mapping, we actually get an "undefined caching policy" one and this has strange side-effects described on Freedesktop bug 86690. To prevent this from happening, allow user-space to explicitly specify which objects should be coherent, and create such objects with the TTM_PL_FLAG_UNCACHED flag. This will make TTM allocate memory using the DMA API, which will fix the identify mapping and allow us to safely map the objects to user-space uncached. Signed-off-by:

Let GK20A's instmem take advantage of the IOMMU if it is present. Having an IOMMU means that instmem is no longer allocated using the DMA API, but instead obtained through page_alloc and made contiguous to the GPU by IOMMU mappings. Signed-off-by:

Tegra SoCs have an IOMMU that can be used to present non-contiguous physical memory as contiguous to the GPU and maximize the use of large pages in the GPU MMU, leading to performance gains. This patch adds support for probing such a IOMMU if present and make its properties available in the nouveau_platform_gpu structure so subsystems can take advantage of it. Signed-off-by:

instmem for GK20A is allocated using dma_alloc_coherent(), which provides us with a coherent CPU mapping that we never use because instmem objects are accessed through PRAMIN. Switch to dma_alloc_attrs() which gives us the option to dismiss that CPU mapping and free up some CPU virtual space. Signed-off-by:

GK20A does not have dedicated RAM, thus having a RAM device for it does not make sense. Move the contiguous physical memory allocation to instmem. Signed-off-by:

Alexandre Courbot authored
Having a RAM device does not make sense for chips like GK20A which have no dedicated video memory. The dummy RAM device that we used so far works as a temporary band-aid, but in the longer term it is desirable for the driver to be able to work without any kind of VRAM. This patch adds a few conditionals in places where a RAM device was assumed to be present and allows some more objects to be allocated from the TT domain, allowing Nouveau to handle GPUs for which pfb->ram == NULL.
