Fixes bug on Tegra where we'd strip kind information from system memory (ie. all) buffers, resulting in misrendering. Behaviour on dGPU should be unchanged. Reported-by:

While the Tegra (GK20A, GM20B, GP10B) MMUs support large pages in host memory, we're currently lacking IOMMU support for merging system pages into large enough chunks to be mapped as such by the GPU. The core VMM code actually supports automatically determining the best page size to map with, which is intended for these situations, but for various complicated reasons the DRM is currently forcing the page size selection on a per-BO basis. This should fix breakage reported on Tegra GPUs in the meantime, until one or both of the above issues are resolved properly. Reported-by:

On my GP107 when I load nouveau after unloading it, for some reason the GPU stopped sending or the CPU stopped receiving interrupts if MSI was enabled. Doing a rearm once before getting any interrupts fixes this. Signed-off-by:

When the fbcon object is initialized, but nouveau_fbcon_create is not called, we run into a NULL pointer access within nouveau_fbcon_create when unloading nouveau. The call to drm_fb_helper_funcs.fb_probe is deferred until there is a display for real since 4.14, that's why fbcon->helper.fb is still not set. Signed-off-by:

Don't populate arrays hwsq_signature and edid_sig on the stack but instead make them static. Makes the object code smaller by over 190 bytes: Before: text data bss dec hex filename 35676 3312 64 39052 988c nouveau_bios.o After: text data bss dec hex filename 35319 3472 64 38855 97c7 nouveau_bios.o (gcc version 7.2.0 x86_64) Signed-off-by:

VMAs are about to not take references on the VMM they belong to, which means more care is required when handling delayed unmapping. Queuing it on the client workqueue ensures all pending VMA unmaps will have completed before the VMM is destroyed. Signed-off-by: -

This is already handled in the top-level gem_new() ioctl in another manner, but this will be removed in a future commit. Ideally we'd not need to check up-front at all, and let the VMM code handle error checking, but there are paths in the current BO management code where this isn't possible due to map() not always being called during BO creation, and map() calls not being allowed to fail during buffer migration.

If the VMA is being deleted, we don't need to explicity unmap first anymore. The MMU code will automatically merge the operations into a single page tree walk. Signed-off-by:
