STRUCT DRM_GPUSVM_CTX(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct drm_gpusvm_ctx(9) — DRM GPU SVM context 🎀

okay bestie, welcome to the Kernel API Manual — yes we're in the kernel today, and yes you're gonna slay it. this page is literally all about struct drm_gpusvm_ctx, the DRM GPU SVM context. it's giving "user arguments but make it a struct." let's get into it 🦋

✨ NAME ✨

struct drm_gpusvm_ctx — the DRM GPU SVM context, periodt. no cap, that's the whole vibe 💅

🫶 SYNOPSIS 🫶

here's the struct in all its iconic glory — copy it exactly, don't you dare touch a single space:

struct drm_gpusvm_ctx {
    void *device_private_page_owner;
    unsigned long check_pages_threshold;
    unsigned long timeslice_ms;
    unsigned int in_notifier :1;
    unsigned int read_only :1;
    unsigned int devmem_possible :1;
    unsigned int devmem_only :1;
    unsigned int allow_mixed :1;
 };

look at those bitfields. chef's kiss 🧚

🌸 Members 🌸

  • device_private_page_owner — the device-private page owner you're rolling with for this operation. it's the main character of this field, fr fr 👑
  • check_pages_threshold — check CPU pages for present if the chunk is less than or equal to this threshold. and if it's not present? reduce the chunk size. simple as that 💖
  • timeslice_ms — the timeslice MS, which is the minimum time a piece of memory remains with either exclusive GPU or CPU access. like a custody arrangement but for memory 😭
  • in_notifier — entering from a MMU notifier 🦋
  • read_only — operating on read-only memory. hands off 🔥
  • devmem_possible — possible to use device memory ✨
  • devmem_only — use only device memory. no mixing, no sharing, we're exclusive 💀
  • allow_mixed — allow mixed mappings in get pages. mixing between system and single dpagemap is supported, but mixing between multiple dpagemap is unsupported. so like, know the difference, iykyk 🙈

⭐ Description ⭐

this is the context that DRM GPUSVM is operating in — basically, it's the user arguments. the whole vibe check of "what are we even doing here." 🌈

okay that's the whole page, you ate that 🍓 mwah, go read the range and notifier pages next, ily! 💖✨🎀
