dce_v10_0_hpd_init(9)
π dce_v10_0_hpd_init(9) β like, the hpd setup callback, bestie β¨
okay so real quick: this is from the Kernel API Manual, and it's the whole tea on dce_v10_0_hpd_init β the hpd setup callback. yes that's a lot of underscores, no we're not changing them, they're iconic π
πΈ SYNOPSIS πΈ
void dce_v10_0_hpd_init (struct amdgpu_device *adev );
that's it. that's the whole signature. it returns void (so like, nothing, she gives nothing back and honestly same) π
π«Ά ARGUMENTS π«Ά
adevβ anamdgpu_devicepointer. that's the vibe, that's the whole parameter, she's the main character here π
β¨ DESCRIPTION β¨
so what does she do? she sets up the hpd pins used by the card (evergreen+, iykyk π). that's the whole job. and she does it in three (3) little steps, no cap:
- enable the pin β
- set the polarity π
- enable the hpd interrupts π₯
that's it, that's the function, she ate and left no crumbs π
π¦ SEE ALSO π¦
the kernel file she lives in, for when you wanna go read the source yourself (respect, honestly):
./drivers/gpu/drm/amd/amdgpu/dce_v10_0.c
and the whole friend group, all of them, every single one, no gatekeeping π«Ά:

like, that's a lot of bandwidth functions and tbh they're all serving π but they're all there, every last one.
ngl there are no warnings, no exit statuses, no environment variables and no options in this one β she's a simple girlie with a simple job. don't go looking for drama where there isn't any π
and that's the page!! mwah π this lil slice of the Kernel API Manual comes to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026 β slay, see you in the next one bestie, stan dce_v10_0_hpd_init(9) π
