STRUCT STUB_DPM_CONTEXT(9)

📦 version 7.3.1, in nixpkgs unstable

✨ struct stub_dpm_context(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 — this is the page where we talk about struct stub_dpm_context, and honestly? It's giving "notebook where every fake DPM callback writes down what it did." 🎀

🌸 NAME 🌸

struct stub_dpm_context — literally just Tracks stub DPM callback invocations 🦋

🫶 SYNOPSIS 🫶

struct stub_dpm_context {
    int ret_val;
    struct amd_pp_clock_info get_current_clocks_info;
    struct amd_pp_clocks get_clock_by_type_clocks;
    struct amd_pp_simple_clock_info get_validation_clks;
    int get_validation_clks_ret;
    struct pp_clock_levels_with_latency
get_clock_by_type_with_latency_clks;
    struct pp_clock_levels_with_voltage
get_clock_by_type_with_voltage_clks;
    int set_watermarks_ret;
    int display_clock_voltage_ret;
    int display_disable_memory_clock_switch_ret;
    int get_max_sustainable_ret;
    int get_uclk_dpm_ret;
    int get_dpm_clock_table_ret;
    int set_active_display_count_ret;
    int set_min_deep_sleep_dcefclk_ret;
 };

no cap, that's the whole struct, copied exactly, line breaks and all — don't @ me 😭

bestie there are so many of these and I'm listing every single one, periodt 👑

and that's the whole page, bestie, iykyk 🌈

mwah 💋 — this cutie came from the source path ./drivers/gpu/drm/amd/display/..., dated October 2026, and it's page struct stub_dpm_context(9) all the way down. go read the tests, they ate 🔥
