STRUCT DRM_I915_GEM_CONTEXT_PARAM(9)

💖 NAME 💖

struct drm_i915_gem_context_param — Context parameter to set or query. That's the whole name, bestie, and yes we're on the struct drm_i915_gem_context_param(9) page in the Kernel API Manual. It's giving "kernel struct that wants to know your context parameter" energy, and we're obsessed 🫶.

✨ SYNOPSIS ✨

okay so here's the struct, copied with love and zero creative rewriting, because the details are literally the moment:

struct drm_i915_gem_context_param {
    __u32 ctx_id;
    __u32 size;
    __u64 param;
  #define I915_CONTEXT_PARAM_BAN_PERIOD   0x1;
  #define I915_CONTEXT_PARAM_NO_ZEROMAP   0x2;
  #define I915_CONTEXT_PARAM_GTT_SIZE     0x3;
  #define I915_CONTEXT_PARAM_NO_ERROR_CAPTURE     0x4;
  #define I915_CONTEXT_PARAM_BANNABLE     0x5;
  #define I915_CONTEXT_PARAM_PRIORITY     0x6;
  #define I915_CONTEXT_MAX_USER_PRIORITY        1023 ;
  #define I915_CONTEXT_DEFAULT_PRIORITY         0;
  #define I915_CONTEXT_MIN_USER_PRIORITY        -1023 ;
  #define I915_CONTEXT_PARAM_SSEU         0x7;
  #define I915_CONTEXT_PARAM_RECOVERABLE  0x8;
  #define I915_CONTEXT_PARAM_VM           0x9;
  #define I915_CONTEXT_PARAM_ENGINES      0xa;
  #define I915_CONTEXT_PARAM_PERSISTENCE  0xb;
  #define I915_CONTEXT_PARAM_RINGSIZE     0xc;
  #define I915_CONTEXT_PARAM_PROTECTED_CONTENT    0xd;
  #define I915_CONTEXT_PARAM_LOW_LATENCY          0xe;
  #define I915_CONTEXT_PARAM_CONTEXT_IMAGE        0xf;
    __u64 value;
};

those #defines are literally part of the block, semicolons and spacing and all — no cap, do not come for me, I don't make the rules 💅.

• ctx_id — Context id. literally the context id, no notes.
• size — Size of the parameter value. how big the value is, slay.
• param — Parameter to set or query. the thing you're setting or querying, iykyk.
• value — Context parameter value to be set or queried. the actual value itself, periodt.
