dc_validate_global_state(9)

💅 dc_validate_global_state — like, the whole vibe check for your GPU state ✨

okay so real talk: this is a page from the Kernel API Manual, section 9, and it's about dc_validate_global_state — the function that looks at a proposed display state and goes "mm, can the hardware actually do this tho?" 🫶

---

🌸 NAME 🌸

dc_validate_global_state — literally determines if the hardware can support a given state 💖

---

🎀 SYNOPSIS 🎀

enum dc_status dc_validate_global_state (struct dc *dc , struct dc_state
*new_ctx , enum dc_validate_mode validate_mode );

---

🦋 ARGUMENTS 🦋

• dc — the dc struct for this driver, bestie. that's the whole context, no cap ✨
• new_ctx — the state that's getting validated 👀 like, this is the candidate, this is who we're judging
• validate_mode — identifies the validation mode 💫 (yes, it tells us which mode we're validating in, she's the vibe-setter)

---

💜 DESCRIPTION 💜

Checks hardware resource availability and bandwidth requirement 🔥

that's it, that's the whole thing — it's giving "can the silicon handle this, or are we delulu?" 💀

---

🌈 RETURN 🌈

DC_OK if the result can be programmed 👑 otherwise, an error code 😭 (and you will respect the error code, periodt)

⭐ SEE ALSO ⭐

• Kernel file ./drivers/gpu/drm/amd/display/dc/core/dc_resource.c — like, the actual source, iykyk 🧚
• resource_validate_probe_set(9)
• dc_validate_with_context(9)
• dc_update_modified_pix_clock_for_dsc_with_padding(9)
• calculate_timing_params_for_dsc_with_padding(9)

all of these are her friends, they run in the same friend group 🫶

okay so that's the whole page!! this one came out of ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — yes, the future, she's ahead of her time 💅✨ no cap, go validate some global state, you've got this 🎀
