commit 46741e4f593ff1bd0e4a140ab7e566701946484b upstream. I've got HW now, appears to work as expected so far.

2021-11-18ce/gf100: fix incorrect CE0 address calculation on some GPUsBen Skeggs1-2/+1
commit 93f43ed81abec8c805e1b77eb1d20dbc51a24dc4 upstream. The code which constructs the modules for each engine present on the GPU passes -1 for 'instance' on non-instanced engines, which affects how the name for a sub-device is generated. This is then stored as 'instance 0' in nvkm_subdev.inst, so code can potentially be shared with earlier GPUs that only had a single instance of an engine. However, GF100's CE constructor uses this value to calculate the address of its falcon before it's translated, resulting in CE0 getting the wrong address. This slightly modifies the approach, always passing a valid instance for engines that *can* have multiple copies, and having the code for earlier GPUs explicitly ask for non-instanced name generation.

2021-10-06drm/nouveau/ga102-: support ttm buffer moves via copy engineBen Skeggs1-0/+3
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>
2021-09-20drm/nouveau/nvkm: Replace -ENOSYS with -ENODEVGuenter Roeck1-1/+1
nvkm test builds fail with the following error. drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c: In function 'nvkm_control_mthd_pstate_info': drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c:60:35: error: overflow in conversion from 'int' to '__s8' {aka 'signed char'} changes value from '-251' to '5' The code builds on most architectures, but fails on parisc where ENOSYS is defined as 251. Replace the error code with -ENODEV (-19). The actual error code does not really matter and is not passed to userspace - it just has to be negative.

2021-08-18drm/nouveau: block a bunch of classes from userspaceBen Skeggs1-1/+1
Long ago, there had been plans for making use of a bunch of these APIs from userspace and there's various checks in place to stop misbehaving. Countless other projects have occurred in the meantime, and the pieces didn't finish falling into place for that to happen. They will (hopefully) in the not-too-distant future, but it won't look quite as insane. The super checks are causing problems right now, and are going to be removed.
