panthor_vm_heaps_sizes(9)

🎀 panthor_vm_heaps_sizes(9) 🎀

okay so welcome to the Kernel API Manual entry for panthor_vm_heaps_sizes(9), bestie. This is the function that does the heap-chunk math for a VM, and we’re gonna read it like a group chat. 💅✨

🌸 NAME 🌸

panthor_vm_heaps_sizes — Calculate size of all heap chunks across all heaps over all the heap pools in a VM. 💖

✨ SYNOPSIS ✨

void panthor_vm_heaps_sizes (struct panthor_file *pfile , struct
drm_memory_stats *stats );

🧚 ARGUMENTS 🧚

• pfile — File. 🎀
• stats — Memory stats to be updated. 🌟

🦋 DESCRIPTION 🦋

So here’s the vibe: she calculates all heap chunk sizes in all heap pools bound to a VM. Literally all of them, no cap. And if the VM is active, she records the size as active as well. ✅

she’s not doing vibes-only math here — this is heap chunk size bookkeeping for a VM, and the active thing gets tracked as active. 💅
