✨ radeon_gart_table_ram_alloc(9) ✨

okay so this is a page from the Kernel API Manual, and bestie, we're talking about radeon_gart_table_ram_alloc today. it's giving "niche GPU driver internals" and honestly? iconic. let's get into it 💅

🌸 NAME 🌸

radeon_gart_table_ram_alloc — allocate system ram for the gart page table 🎀

---

🦋 SYNOPSIS 🦋

int radeon_gart_table_ram_alloc (struct radeon_device *rdev );

---

💖 ARGUMENTS 💖

• rdev — a radeon_device pointer, that's it, that's the whole arg 🫶

---

⭐ DESCRIPTION ⭐

so what this does is allocate system memory for the GART page table. and before you ask — yes, specifically for these ones: r1xx-r3xx, non-pcie r4xx, and rs400. those ASICs lowkey require the gart table to live in system memory, no cap. it's just how they're built 😭

returns 0 for success, and -ENOMEM if it fails (aka the memory allocation said "not today" 💀).
