Engine context tracking will move to nvkm_cgrp in later commits, so we create SW-only channel groups on HW without support for them. - switches to nvkm_chid for TSG/channel ID allocation Signed-off-by:

DRM uses this to setup fence-related items. - nouveau_chan.runlist will always be "0" for the moment, not an issue as GPUs prior to ampere have system-wide channel IDs, Signed-off-by:

Previously only available from Kepler onwards. - also fixes the info() queries causing fifo init()/fini() unnecessarily Signed-off-by:

Ben Skeggs authored
Creates an nvkm_runl for each runlist on the GPU, and an nvkm_engn for each engine that is reachable from a runlist. - basically what gk104- already does, but extended to all chips - adds per-runlist CHID allocators (Ampere) - splits g98/gt2xx out from g84 (different target engines) Signed-off-by:

Creates an nvkm_runq for each PBDMA, these will be associated with the relevant runlist(s) later. Signed-off-by:

We need to be able to allocate TSG IDs as well as channel IDs, also, Ampere has per-runlist channel IDs. - holds per-ID private data, which will be used for/to protect lookup - holds an nvkm_event which will be used for events tied to IDs - not used yet beyond setup, and switching use of "fifo->nr - 1" for channel ID mask to "chid->mask" Signed-off-by:

This makes it easier to transition everything. - a couple of function renames for collisions Signed-off-by:

Adds the basic skeleton for common channel (group) interfaces. - common behaviour between <gk104 and >=gk104 impl's - separates priv/user channel objects - passthrough to existing object for now, kludges removed later Signed-off-by:

- reads channel count from GPU from gm200 onwards - removes gm20b/gp10b (they become identical to gm200/gp100) Signed-off-by:

Will be used to init client-allocated USERD to default values. Signed-off-by:

Displays both owner/user of the falcon (when they differ), and takes both subdevs' debug levels into account when deciding whether to log the message. - runlist debugging will use one of the alternate macros added here Signed-off-by:

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:

- NV_PMC_ENABLE still exists, but we don't touch anything in it yet Signed-off-by:
-
Ben Skeggs authored
Ampere needs different handling here, most of what we touch has moved. We probably want to refactor these interfaces in general, but I'm not yet sure how they should look, this will get the job done for now. Signed-off-by:
-

- new-style handlers can now be used here too - decent clean-up Signed-off-by:

Initially for NV_USERMODE class, and Turing/Ampere's new interrupt tree. v2. fixup for ga103 early merge Signed-off-by: -
Ben Skeggs authored
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. This will allow a more gradual transition. Signed-off-by:

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. Signed-off-by:

Unifies the handling between PCI-based and Tegra GPUs, and makes more explicit/obvious where device interrupts can be expected. Signed-off-by:

We're going to want this information available earlier than it is now. Signed-off-by:

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:

This removes support for accelerated fbcon rendering, and fixes a number of races/crashes/issues around suspend/resume/module unload etc. Losing HW accelerated rendering isn't ideal, but it's been significantly reduced in performance since the removal of accelerated scrolling in the kernel anyway - not to mention, can be racey (skips cpu<->gpu sync) from certain contexts.

This replaces the twisty, confusing, relationship between nvkm_event and nvkm_notify with something much simpler, and less racey. It also places events in the object tree hierarchy, which will allow a heap of the code tracking events across allocation/teardown/suspend to be removed. This commit just adds the new interfaces, and passes the owning subdev to the event constructor to enable debug-tracing in the new code. v2: - use ?: (lyude) Signed-off-by:
