2025-05-19drm/nouveau: add support for GB20xBen Skeggs
This commit adds support for the GB20x GPUs found on GeForce RTX 50xx series boards. Beyond a few miscellaneous register moves and HW class ID plumbing, this reuses most of the code added to support GH100/GB10x.

2025-05-19drm/nouveau: improve handling of 64-bit BARsBen Skeggs
GPUs exist now with a 64-bit BAR0, which mean that BAR1 and BAR2's indices (as passed to pci_resource_len() etc) are bumped up by one. Modify nvkm_device.resource_addr/size() to take an enum instead of an integer bar index, and take IORESOURCE_MEM_64 into account when translating to the "raw" bar id.

2025-05-19drm/nouveau/gsp: remove gsp-specific chid allocation pathBen Skeggs
In order to specify a channel ID to RM during channel allocation, the channel ID is broken down into a "userd page" index and an index into that page. It was assumed that RM would enforce that the same physical block of memory be used for all CHIDs within a "userd page", and the GSP paths override NVKM's normal CHID allocation to handle this. However, none of that turns out to be necessary. Remove the GSP-specific code and use the regular CHID allocation path.

Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference.

2023-11-21nouveau/gsp: allocate enough space for all channel ids.Dave Airlie
This probably isn't the ideal fix, but we ended up using chids sparsely, and lots of things rely on indexing into the full range, so just allocate the full range up front. The GSP code fixes 8 channels into a userd page, but we end up using a single userd page per channel so end up sparsely using the range. Fixes a few crashes seen with multiple channels.

2022-11-09drm/nouveau/fifo: add new engine context trackingBen Skeggs
Channel groups have somewhat more complicated requirements than what we currently support. An engine context is shared between all channels in a channel group, VEID/subctx support (later) brings per-VEID components, and we need to track an individual channel's engine context pointers. This commit adds the structures and refcounting to support the above, wrapping the prior implementation for the moment.

2022-11-09drm/nouveau/fifo: merge mmu fault handlers togetherBen Skeggs
After updating GF100 implementation from the GK104/TU102 ones, and using the new runlist/engine topology info, all three handlers become (almost) identical. - there's a temporary kludge to call through to the HW-specific recovery - engine fault mapping info determined at load time, not on every fault Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>
