DRIVER MODES OF OPERATION IN TERMS OF DISPLAY BUFFERS USED(9)

🦋 Driver modes of operation in terms of display buffers used 🦋

okay so you're reading Driver modes...buffers used(9) from the Kernel API Manual, and it's lowkey all about who gets to hold the display buffers 💅✨

Depending on the requirements for the para-virtualized environment — and yeah, those requirements are dictated by the accompanying DRM/(v)GPU drivers running in both host and guest environments — display buffers can be allocated by either frontend driver or backend. That's the vibe: frontend driver does it, or backend does it. No cap. 🫶

mwah 💋 this lil page comes from ./drivers/gpu/drm/xen, dated October 2026, and its manual name is literally Driver modes...buffers used(9) — periodt, you're welcome 💖🎀
