Commit bbb163e1 ("drm/nouveau/bar: implement bar1 teardown") introduced add a teardown helper function for BAR1. During initialisation of the Nouveau, initially all the teardown helpers are called once, before calling their init counterparts. For gk20a, after the BAR1 teardown function is called, the device is hanging during the initialisation of the FB sub-device. At this point it is unclear why this is happening and this is still under investigation. However, this change is preventing Tegra124 devices from booting when Nouveau is enabled. To allow Tegra124 to boot, remove the teardown helper for gk20a. This is based upon a previous patch by Guillaume Tucker but limits the workaround to only gk20a GPUs.

This is obviously wrong in the current code. Make sure to record the correct size of the arguments and pass the actual arguments to the nvif_object_map_handle() function. Suggested-by:

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:

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.
