MAX_SURFACES(9)

💅 MAX_SURFACES(9) — a whole kernel API manual page, bestie

okay so real talk, this one's a shortie but she's important. We're in the MAX_SURFACES zone of the kernel API manual, and honestly? she's carrying the whole vibe of "how many surfaces can we even stack on one CRTC."

✨ NAME ✨

MAX_SURFACES — no cap, she's literally the representative of the upper bound of surfaces that can be piped to a single CRTC 🫶

like, think of CRTC as the one main-character display pipeline, and MAX_SURFACES is the bouncer at the door going "bestie, that's the limit, we can't let any more in." iconic behavior honestly.

🌸 SYNOPSIS 🌸

MAX_SURFACES

yes that's it. that's the whole synopsis. no arguments, no flags, no nothing — she just is. minimalism ate and left no crumbs 💅

🦋 SEE ALSO 🦋

okay this is the part where she name-drops literally everyone in her contacts. buckle up, we're going through the whole group chat:

• Kernel file ./drivers/gpu/drm/amd/display/dc/dc.h MAX_PLANES(9) — the sibling, the one everyone confuses her with
• color-management-caps(9)
• struct rom_curve_caps(9)
• struct dpp_color_caps(9)
• struct mpc_color_caps(9)
• struct dc_color_caps(9)
• enum pipe_split_policy(9)
• dc_check_state_update(9)
• dc_update_state(9)
• dc_update_state_init(9)
• dc_update_state_prepare(9)
• dc_update_state_execute(9)
• dc_update_state_cleanup(9)
• struct dc_probe_latencies(9)
• struct dc_probe_status(9)
• enum dc_get_status_type(9)
• struct dc_get_status_options(9)
• struct dc_state_status(9)
• dc_state_get_status(9)
• struct dc_validation_stream(9)
• struct dc_validation_set(9)
• dc_get_underflow_debug_data_for_otg(9)
• dc_capture_register_software_state(9)
• dc_get_qos_info(9)
• dc_override_memory_bandwidth_request(9)

fr fr, go read MAX_PLANES(9) next if you want the full lore drop — they're giving sibling energy and the whole state-update pipeline (dc_update_state*, dc_check_state_update) is lowkey the main character arc here. iykyk 💖

🎀 a lil sign-off 🎀

this absolute gem lives over in ./drivers/gpu/drm/amd/display/dc, and she's stamped October 2026 — so yeah, mark your calendar bestie, that's the version/date situation. go forth and respect the surface limit, periodt 💜🔥
