DRIVER LIMITATIONS(9)

💖 Driver limitations 💖

okay bestie, welcome to the Kernel API Manual page for Driver limitations(9) — this is the vibe check on what this driver can and cannot do ✨. These aren’t suggestions, they’re the actual limits, so lock in:

1. Only the primary plane is supported, and it comes with no additional properties. That’s it. That’s the whole plane situation 💅.
2. Only one video mode per connector is supported, and it’s configured via XenStore. One mode, no cap, don’t try to sneak in more 🎀.
3. All CRTCs operate at a fixed frequency of 60Hz. Not flexible, not negotiable — 60Hz is the main character ⏰.
