drm_get_edid_switcheroo(9)

💅 drm_get_edid_switcheroo(9) 💅

okay so welcome to the Kernel API Manual, bestie — this page is all about drm_get_edid_switcheroo, and it’s giving “tiny wrapper, very specific laptop job” energy. no cap. 🫶

✨ NAME ✨

drm_get_edid_switcheroo — get EDID data for a vga_switcheroo output. literally that’s the vibe. 💖

🎀 SYNOPSIS 🎀

struct edid * drm_get_edid_switcheroo (struct drm_connector *connector ,
       struct i2c_adapter *adapter );

🦋 ARGUMENTS 🦋

• connector — the connector we’re probing. that’s the one, bestie. 👀
• adapter — the I2C adapter to use for DDC. iconic little detail. ✨

🌸 DESCRIPTION 🌸

okay so picture this: it’s a wrapper around drm_get_edid for laptops with dual GPUs using one set of outputs. yes, those ones. 💻💻

the way that this wrapper works is that it adds the requisite vga_switcheroo calls to temporarily switch DDC to the GPU which is retrieving EDID. so it’s not just vibes — there are actual switcheroo calls doing the work. periodt. 🔥

💖 RETURN 💖

returns a pointer to valid EDID, or NULL if we couldn’t find any. that’s the whole return story, no plot twist. 😭
