STRUCT EU_STALL_OPEN_PROPERTIES(9)

🌸 NAME 🌸

Okay so this is the struct eu_s...n_properties(9) page from the Kernel API Manual, section 9, and we're talking about struct eu_stall_open_properties — literally the EU stall sampling properties received from user space at open. That's the vibe. 💖

🦋 SYNOPSIS 🦋

       struct eu_stall_open_properties {
           int sampling_rate_mult;
           int wait_num_reports;
           struct xe_gt *gt;
        };

💅 Members 💅

• sampling_rate_mult — bestie, this is the EU stall sampling rate multiplier ✨. The HW will sample every (sampling_rate_mult x 251) cycles. No cap, that's the math.
• wait_num_reports — the minimum number of EU stall data reports needed to unblock poll 🫶. Think of it as the "okay we have enough, wake up" threshold.
• gt — the GT on which EU stall data will be captured 👑. That's the main-character GT for this whole sampling situation.

Later bestie 💅 — this cutie came from source/version ./drivers/gpu/drm/xe, dated October 2026, and it's still out here living as struct eu_s...n_properties(9) 🎀🦋
