2024-08-27Merge v6.11-rc5 into drm-nextDaniel Vetter
amdgpu pr conconflicts due to patches cherry-picked to -fixes, I might as well catch up with a backmerge and handle them all. Plus both misc and intel maintainers asked for a backmerge anyway. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2024-07-27drm/nouveau/nvif: remove disp chan rd/wrBen Skeggs
There's no good reason the ioremap() that results from nvif_object_map() should fail, so add a check that the map succeeded, and remove the rd/wr methods from display channel objects. As this was the last user of rd/wr methods, the nvif plumbing is removed at the same time.

2024-07-27drm/nouveau/nvif: remove client device argBen Skeggs
This was once used by userspace tools (with nvkm built as a library), as a way to select a "default device". The DRM code doesn't need this at all as clients only have access to a single device already, so inherit the value from its parent.

These were a cludge used to prevent userspace's nvif ioctl from accessing objects created by the kernel for the same client. That interface was removed in a previous patch, so these are no longer useful for anything.

2023-09-15drm/nouveau/core: refactor deprecated strncpyJustin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. There is likely no bug in the current implementation due to the safeguard: | cname[sizeof(cname) - 1] = '\0'; ... however we can provide simpler and easier to understand code using the newer (and recommended) `strscpy` api.

2023-07-06drm/nouveau/nvkm: fini object children in reverse orderBen Skeggs
Turns out, we're currently tearing down the disp core channel *before* the satellite channels (wndw, etc) during suspend. This makes RM return NV_ERR_NOT_SUPPORTED on attempting to reallocate the core channel on resume for some reason, but we probably shouldn't be doing it on HW either. Tear down children in the reverse of allocation order instead.

Adds the start of common interfaces to load and boot the HS binaries provided by NVIDIA that enable the usage of GR. ACR already handles most of this, but it's very much tied into ACR's init process, and there's other code that could benefit from reusing a lot of this stuff too (ie. VBIOS DEVINIT/PreOS, VPR scrubber). The VPR scrubber code is fairly independent, and a good first target. - adds better debug output to fw loading process, to ease bring-up/debug v2: - whitespace, 0->false Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>
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/nvkm: add locking to subdev/engine init pathsBen Skeggs
This wasn't really needed before; the main place this could race is with channel recovery, but (through potentially fragile means) shouldn't have been possible. However, a number of upcoming patches benefit from having better control over subdev init, necessitating some improvements here. - allows subdev/engine oneinit() without init() (host/fifo patches) - merges engine use locking/tracking into subdev, and extends it to fix some issues that will arise with future usage patterns (acr patches) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>

2022-11-09drm/nouveau/intr: add nvkm_subdev_intr() compatibilityBen Skeggs
It's quite a lot of tedious and error-prone work to switch over all the subdevs at once, so allow an nvkm_intr to request new-style handlers to be created that wrap the existing interfaces.

2022-11-09drm/nouveau/intr: support multiple trees, and explicit interfacesBen Skeggs
Turing adds a second top-level interrupt tree in HW, in addition to the trees available via NV_PMC. Most of the interrupts we care about are exposed in both trees, but not all of them, and we have some rather nasty hacks to route the fault buffer interrupts. Ampere removes the NV_PMC trees entirely. Here we add some infrastructure to be able to handle all of this more cleanly, as well as providing more explicit control over handlers.

2022-11-09drm/nouveau/nvkm: give each nvkm_event its own lockdep classBen Skeggs
The vblank and nonstall events have some annoying interactions with DRM locking, and aren't able to do certain things as a result. However, other uses of event notifications don't have such requirements, and upcoming patches take advantage of this for various improvements. Having separate classes for each nvkm_event's spinlocks allows lockdep to distinguish between them and avoid false-positives. v2: __always_inline + comment Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>
