2023-10-31drm/nouveau/fault/tu102-: prepare for GSP-RMBen Skeggs1-1/+7
- disable FAULT completely when GSP-RM detected - SVM support will be disabled when running on RM because of this Signed-off-by: Ben Skeggs <[email protected]> Signed-off-by: Dave Airlie <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2022-11-09drm/nouveau/fault/tu102: switch to explicit intr handlersBen Skeggs2-59/+50
- reads vectors from HW, rather than being hardcoded - removes hacks to support routing via old interfaces Signed-off-by: Ben Skeggs <[email protected]> Reviewed-by: Lyude Paul <[email protected]>

2022-11-09drm/nouveau/nvkm: add a replacement for nvkm_notifyBen Skeggs1-2/+1
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: Ben Skeggs <[email protected]> Reviewed-by: Lyude Paul <[email protected]>

2021-01-29drm/nouveau/mc/tu102: Fix MMU fault interrupts on TuringAlistair Popple1-1/+20
Turing reports MMU fault interrupts via new top level interrupt registers. The old PMC MMU interrupt vector is not used by the HW. This means we can remap the new top-level MMU interrupt to the exisiting PMC MMU bit which simplifies the implementation until all interrupts are moved over to using the new top level registers.

2020-01-15drm/nouveau/fault: Add support for GP10BThierry Reding6-6/+78
There is no BAR2 on GP10B and there is no need to map through BAR2 because all memory is shared between the GPU and the CPU. Add a custom implementation of the fault sub-device that uses nvkm_memory_addr() instead of nvkm_memory_bar2() to return the address of a pinned fault buffer.

2019-07-19drm/nouveau: fix bogus GPL-2 license headerBen Skeggs1-1/+1
The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files were simply missing the boiler plate and got caught up in the global update.

2018-12-11drm/nouveau/fault/tu104: initial supportBen Skeggs4-1/+171
New registers. Currently uncertain how exactly to mask fault buffer interrupts. This will likely be corrected at around the same time as the new MC interrupt stuff has been properly figured out and implemented. For the moment, it shouldn't matter too much.

2018-12-11drm/nouveau/fault: add explicit control over fault buffer interruptsBen Skeggs4-8/+29
The GPU will continually fire interrupts while a fault buffer GET != PUT, and to stop the spurious interrupts while the handler does its thing, we were disabling the fault buffer temporarily. This is not actually a great idea to begin with, and made worse by Volta resetting GET/PUT when it's reactivated. So, let's not do that. Signed-off-by: Ben Skeggs <[email protected]>
