similar to: [PATCH -next] drm/ttm: remove unnecessary conversion to bool

Drivers have no business looking into dma-mapping internals and check what backend is used. Unfortunstely the DRM core is still broken and tries to do plain page allocations instead of using DMA API allocators by default and uses various bandaids on when to use dma_alloc_coherent. Switch nouveau to use the same (broken) scheme as amdgpu and radeon to remove the last driver user of

Pass gem vma_offset_manager to ttm_bo_device_init(), so ttm uses it instead of its own embedded struct. This makes some gem functions (specifically drm_gem_object_lookup) work on ttm objects.

Dear nouveau mailing list, on my notebook with the GeForce GT 240M graphics card, I am failing to start sddm since linux kernel 6.5.0. The screen typically goes black or white, mouse pointer is typically visible and can be moved. This happens about 90% of times I try to start the system; in about 10%, everything works fine. If the start fails, dmesg shows output such as: [?? 20.260153] nouveau

Rename the embedded struct vma_offset_manager, new name is _vma_manager. ttm_bo_device.vma_manager changed to a pointer. The ttm_bo_device_init() function gets an additional vma_manager argument which allows to initialize ttm with a different vma manager. When passing NULL the embedded _vma_manager is used. All callers are updated to pass NULL, so the behavior doesn't change. Signed-off-by:

Some graphics APIs differentiate between out-of-graphics-memory and out-of-host-memory (system memory). Add a device init flag to have -ENOSPC propagated from the resource managers instead of being converted to -ENOMEM, to aid driver stacks in determining what error code to return or whether corrective action can be taken at the driver level. The first patch deals with a ttm_device_init()

Most graphics cards nowadays have a multiple of this limit as their vram, so limiting GART doesn't seem to make much sense.

The T124 generation of Tegra GPUs uses the Kepler architecture and can thus be driven by Nouveau. However, they are declared as platform devices using the Device Tree, and Nouveau has a very strong dependency on PCI. This patch makes Nouveau core able to handle platform devices as well as PCI devices. Commonly-used PCI functions include resource range query and page mapping. These functions are
