========== original bug descriptions ==========
An issue has come up with MI300 OEM deployments where, due to the
current limit of 64 drm device nodes in the kernel, MI300 systems with
an integrated display (e.g., mgag200 or ast) fail to light up the
console because the AMD GPU driver has used up all of the drm device
nodes. A patch set recently landed in drm-misc to extend the number of
device nodes. These are the relevant commits:
