2022-07-27drm/nouveau/disp: add output classBen Skeggs1-0/+1
Will be used to more cleanly implement existing method interfaces that take some confusing (IEDTkey, inherited from VBIOS, which RM no longer uses on Ampere) match values to determine which display path to operate on. Methods will be protected from racing with supervisor, and from being called where they shouldn't be (ie. without an OR assigned). v2: - use ?: (lyude) v3: - fix return code if noacquire() method fails Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2022-07-27drm/nouveau/disp: add common channel class handlingBen Skeggs1-0/+1
Replaces a bunch of unnecessarily duplicated boilerplate in per-chipset code with a simpler, common, implementation. Channel "awaken" notify code is completely gone for now. KMS has never made use of it so far, and event notify handling is about to be changed in general anyway.

2022-05-04drm/nouveau/subdev/bus: Ratelimit logging for fault errorsLyude Paul1-0/+2
There's plenty of ways to fudge the GPU when developing on nouveau by mistake, some of which can result in nouveau seriously spamming dmesg with fault errors. This can be somewhat annoying, as it can quickly overrun the message buffer (or your terminal emulator's buffer) and get rid of actually useful feedback from the driver. While working on my new atomic only MST branch, I ran into this issue a couple of times. So, let's fix this by adding nvkm_error_ratelimited(), and using it to ratelimit errors from faults. This should be fine for developers, since it's nearly always only the first few faults that we care about seeing. Plus, you can turn off rate limiting in the kernel if you really need to.

2021-10-06drm/nouveau/ga102-: support ttm buffer moves via copy engineBen Skeggs1-0/+1
We don't currently have any kind of real acceleration on Ampere GPUs, but the TTM memcpy() fallback paths aren't really designed to handle copies between different devices, such as on Optimus systems, and result in a kernel OOPS. A few options were investigated to try and fix this, but didn't work out, and likely would have resulted in a very unpleasant experience for users anyway. This commit adds just enough support for setting up a single channel connected to a copy engine, which the kernel can use to accelerate the buffer copies between devices. Userspace has no access to this incomplete channel support, but it's suitable for TTM's needs. A more complete implementation of host(fifo) for Ampere GPUs is in the works, but the required changes are far too invasive that they would be unsuitable to backport to fix this issue on current kernels. v2: fix GPFIFO length in RAMFC (reported by Karol) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: Lyude Paul <lyude@redhat.com> Cc: Karol Herbst <kherbst@redhat.com> Cc: <stable@vger.kernel.org> # v5.12+ Reviewed-by: Karol Herbst <kherbst@redhat.com> Tested-by: Karol Herbst <kherbst@redhat.com> Signed-off-by: Karol Herbst <kherbst@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210916220406.666454-1-skeggsb@gmail.com Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
