✨ panthor_mmu_resume(9) ✨

Straight out of the Kernel API Manual, bestie — we're looking at panthor_mmu_resume(9). Yes, the MMU-resuming one. 🫶

📛 NAME 📛

panthor_mmu_resume — Resume the MMU logic. Iconic behaviour, no notes. 💅

📜 SYNOPSIS 📜

void panthor_mmu_resume (struct panthor_device *ptdev );

🎀 ARGUMENTS 🎀

• ptdev — Device. That's the device, bestie. The whole device. 🫶

🌸 DESCRIPTION 🌸

Okay so first thing: this resumes the IRQ. That's the move. ✨

It does not re-enable previously active VMs — nope, not doing that. The assumption is that other parts of the driver will call panthor_vm_active on the VMs they intend to use. So like, don't expect this function to go digging around in old VM state; that's somebody else's main character moment. 💅
