This will allow us to register the falcon with ACR, and further customise its behaviour by providing the nvkm_falcon_func structure directly. Signed-off-by: -

ACR LS FW loading is moving out of SECBOOT and into their specific subdevs, and the available GM20B/GP10B FWs have interface differences. Signed-off-by: -

Shortcut to avoid each subdev having to do this itself. Signed-off-by: -

We want to be able to register falcons with ACR during the constructor for the subdev it belongs to, however, we may not have access to the falcon's registers prior to DEVINIT. Delay touching registers until the first time the falcon is acquired. This may temporarily break secboot on non-production boards due to not being able to determine whether the falcon is in debug or production mode, the new ACR subdev will not have this issue, and it's not a use-case that's terribly important for bisectability.

Like other cases, it should use rcu protected 'chan' rather than 'fence->channel' in nouveau_fence_wait_uevent_handler. Fixes: 0ec5f02f ("drm/nouveau: prevent stale fence->channel pointers, and protect with rcu") Signed-off-by:

Method init is typically ordered by class in the FW image as ThreeD, TwoD, Compute. Due to a bug in parsing the FW into our internal format, we've been accidentally sending Twod + Compute methods to the ThreeD class, as well as Compute methods to the TwoD class - oops. Signed-off-by: -

We accidentally set "psb" which is a no-op instead of "*psb" so it generates a static checker warning. We should probably set it before the first error return so that it's always initialized. Fixes: 923f1bd2 ("drm/nouveau/secboot/gm20b: add secure boot support") Signed-off-by:

Turing introduced a new simplified page kind scheme, reducing the number of possible page kinds from 256 to 16. It also is the first NVIDIA GPU in which the highest possible page kind value is not reserved as an "invalid" page kind. To address this, the invalid page kind is made an explicit property of the MMU HAL, and a new table of page kinds is added to the tu102 MMU HAL. One hardware change not addressed here is that 0x00 is technically no longer a supported page kind, and pitch surfaces are instead intended to share the block-linear generic page kind 0x06. However, because that will be a rather invasive change to nouveau and 0x00 still works fine in practice on Turing hardware, addressing this new behavior is deferred. Signed-off-by:

The pointer used to walk the table of move ops and pick the right one for the current GPU was declared static, meaning its state was carried over between invocations of the function, and also made the function non-rentrant and thread-unsafe. Since the table is ordered such that newer GPU methods are listed first, the result of this was that initializing newer GPUs after older GPUs would result in no suitable ttm move acceleration operations being found, and ttm would fall back to CPU blits on the older GPUs. This change declares the walking pointer separately from the table and makes it non-static to fix the logic. Signed-off-by:

gp10b uses the new engine enumeration mechanism introduced in the Pascal architecture. As a result, the copy engine, which used to be at index 2 for prior Tegra GPU instantiations, has now moved to index 0. Fix up the index and also use the gp100 variant of the copy engine class because on gp10b the PASCAL_DMA_COPY_B class is not supported. Signed-off-by:

The GPUs found on Tegra SoCs have registers that can be used to read the WPR configuration. Use these registers instead of reaching into the memory controller's register space to read the same information. Signed-off-by:

When the GPU powergate is controlled by a generic power domain provider, the reset will automatically be asserted and deasserted as part of the power-ungating procedure. On some Jetson TX2 boards, doing an additional assert and deassert of the GPU outside of the power-ungate procedure can cause the GPU to go into a bad state where the memory interface can no longer access system memory.
