🦋 ath5k_get_linear_pcdac_min(9) 🦋

okay bestie, welcome to the Kernel API Manual page for ath5k_get_linear_pcdac_min(9) — we're literally about to find the vertical boundary (min pwr) for the linear PCDAC curve, and it's giving "boundary patrol but make it wireless." ✨

💖 NAME 💖

ath5k_get_linear_pcdac_min — Find vertical boundary (min pwr) for the linear PCDAC curve

✨ SYNOPSIS ✨

s16 ath5k_get_linear_pcdac_min (const u8 *stepL , const u8 *stepR ,
       const s16 *pwrL , const s16 *pwrR );

🎀 ARGUMENTS 🎀

• stepL — Left array with y values (pcdac steps)
• stepR — Right array with y values (pcdac steps)
• pwrL — Left array with x values (power steps)
• pwrR — Right array with x values (power steps)

🌸 DESCRIPTION 🌸

so here's the vibe: we already have the top of the curve, and we're drawing the line below it until we reach 1 (1 pcdac step). we need to know which point — the x value — that is, so we don't go below the x axis and end up with negative pcdac values when creating the curve, or fill the table with zeros. literally boundary safety, no cap. 💅
