NVIDIA
Also support T234 in the same driver
NVIDIA Driver Version 34.1 and 515.43.04 GPU AGX Orin and RTX 2080 Ti
Describe the bug AGX Orin already ships with an open-source NVIDIA kernel driver for the display. This means that when we install this driver, we lose the display output tied to the display controller already present on the SoC.
To Reproduce
On an AGX Orin:
$ modinfo 5.10.65-tegra/extra/opensrc-disp/nvidia.ko
filename: /lib/modules/5.10.65-tegra/extra/opensrc-disp/nvidia.ko
firmware: nvidia/34.1.0/gsp.bin
alias: char-major-195-*
version: 34.1.0
supported: external
license: Dual MIT/GPL
srcversion: 92576267C511B79A495FD51
alias: pci:v000010DEd*sv*sd*bc06sc80i00*
alias: pci:v000010DEd*sv*sd*bc03sc02i00*
alias: pci:v000010DEd*sv*sd*bc03sc00i00*
alias: of:N*T*Cnvidia,tegra234-displayC*
alias: of:N*T*Cnvidia,tegra234-display
This conflicts with this driver, which doesn't have T234D support included. (and the driver in L4T doesn't have dGPU support included!)
Expected behavior
This driver should support T234D too (nvidia,tegra234-display). Having two incompatible open-source drivers this early is quite unusual.
Even better change (if possible)
Supporting T234, instead of just the display block-only variant (T234D) in this driver, (and T194 if possible) outright in this driver so that the GPU too would be driven by this instead of nvgpu. That'd help in support for 3rd-party OS distributions on that hardware.
Good suggestion. We do plan to do this in the future, however, we haven't finalized when this would be done. T234D support was added at a time when a major part of this driver (today's release) was not ready, hence we did a lot of pre-processing - some of which needs to be cleaned up before we can have a single driver that supports both big GPUs and T234D.
Sorry, no current update. But this is still something we hope to do eventually.
