💖 gmc_v9_0_save_registers(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for gmc_v9_0_save_registers(9) and it is, no joke, one of the chillest little functions in the whole AMDGPU universe. grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

gmc_v9_0_save_registers — saves regs 💾

that's it. that's the whole name. it saves regs. iconic, honestly.

---

🦋 SYNOPSIS 🦋

void gmc_v9_0_save_registers (struct amdgpu_device *adev );

so like, it returns nothing (void — she gives nothing, she takes nothing, she just does), and it takes exactly one (1) friend along for the ride. 💅

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. that's the whole vibe. it's the device, bestie, it's literally the device pointer, hand it over and let her cook. 🫶

---

🌸 DESCRIPTION 🌸

okay so here's the tea: this function saves potential register values that should be restored upon resume. that's the actual deal — she's out here tucking away register values so that when the system goes to sleep and comes back (resume, iykyk), everything can be put back the way it was. 🧚

it's giving "packing a little overnight bag for your registers" energy. lowkey essential, highkey underrated. ⭐
