💅 amdgpu_gfx_get_enforce_isolation — the Kernel API Manual tea ☕✨

okay so bestie, welcome to the amdgpu_gfx_g...ce_isolation(9) page — yes that's the kernel API manual, and yes we're about to get into it 🫶

---

✨ NAME ✨

amdgpu_gfx_get_enforce_isolation — literally the function that queries your AMDGPU GFX Enforce Isolation settings 🔥

---

🌸 SYNOPSIS 🌸

ssize_t amdgpu_gfx_get_enforce_isolation (struct device *dev , struct
       device_attribute *attr , char *buf );

it's giving "short and iconic" 💅

---

🎀 ARGUMENTS 🎀

• dev — the device structure, like, the main character of this whole operation 👑
• attr — the device attribute structure, showing up so the sysfs machinery knows what's what
• buf — the buffer where the output data gets stored, i.e. where the answer actually lives 🦋

---

🧚 DESCRIPTION 🧚

so what does it do? it provides the sysfs read interface to get the current settings of the 'enforce_isolation' feature for each GPU partition. no cap 💯

reading from the 'enforce_isolation' sysfs file returns the isolation settings for all the partitions, and here's the decoder ring, bestie — memorize it, iykyk:

• '0' indicates disabled 🙈
• '1' indicates enabled ✨
• '2' indicates enabled in legacy mode 💀
• '3' indicates enabled without cleaner shader 🌈

that's it, that's the whole vibe check ✅

---

💖 RETURN 💖

the number of bytes read from the sysfs file. periodt. 🎯
