smu_alloc_memory_pool(9)

💖 smu_alloc_memory_pool(9) 💖

okay so bestie, this is the Kernel API Manual page for smu_alloc_memory_pool — manual name folded in right at the top like a little name tag, because we're cute AND organized. 🫶

🌸 NAME 🌸

smu_alloc_memory_pool — allocate memory pool in the system memory. Short, sweet, and to the point. 💅

✨ SYNOPSIS ✨

int smu_alloc_memory_pool (struct smu_context *smu );

Not me preserving the exact spacing in that signature — code gets copied character-for-character, periodt. 🎀

🎀 ARGUMENTS 🎀

• smu — amdgpu_device pointer. That's the one argument, bestie; she takes the pointer and goes. 💖

🦋 DESCRIPTION 🦋

This memory pool will be used for SMC use and msg. SetSystemVirtualDramAddr and DramLogSetDramAddr can notify it changed. Those two exact names are giving important notification energy, so don't go renaming them, iykyk. ✨

It returns 0 on success, error on failure. Zero is the slay outcome; anything else means something went sideways. 😭
