πŸ’– amdgpu_pm_get_access β€” the Kernel API Manualβ„’ ✨

okay so bestie, this is a page from the Kernel API Manual, and it's about one function: amdgpu_pm_get_access. it's short, it's sweet, and it's lowkey doing important work behind the scenes 🫢


🌸 NAME 🌸

amdgpu_pm_get_access β€” literally just: check if the device can be accessed, and resume it if needed πŸ’…


✨ SYNOPSIS ✨

int amdgpu_pm_get_access (struct amdgpu_device *adev );

that's it. one function, one argument, returns an int. iconic behaviour honestly πŸ‘‘


πŸŽ€ ARGUMENTS πŸŽ€

  • adev β€” the target device. like, the specific struct amdgpu_device you're asking about. that's the whole vibe πŸ¦‹

πŸ’œ DESCRIPTION πŸ’œ

so what does it actually do? it checks the state of adev for access β€” vibe check the device, basically. if the device isn't ready yet, it uses the runtime pm API to resume it, so it can actually be reached πŸ”₯

returns 0 if the device is accessible, or a negative error code otherwise. no cap, that's the whole contract 😭

ngl, always check the return value. negative error code = the device is not giving accessible energy, and you should handle that instead of pretending everything's fine πŸ’€

🌈 SEE ALSO 🌈

the kernel file lives at ./drivers/gpu/drm/amd/pm/amdgpu_pm.c β€” go read it, iykyk πŸ“–

and because this function doesn't exist in a vacuum, here's the whole friend group it runs with:

that's a lot of siblings and honestly? main character energy for the whole amdgpu pm family πŸ‘‘
