π amdgpu_debugfs_regs_pcie64_write β from the Kernel API Manual, bestie
Okay so bestie, this is the manual page for amdgpu_debug...pcie64_write(9) (the header line, we're folding it in right here so you get the whole vibe π). It's a kernel API page, it lives in the Kernel API Manual, and honestly? It's giving "tiny function, big responsibility." Let's get into it π
β¨ NAME β¨
amdgpu_debugfs_regs_pcie64_write β literally just writes to a 64-bit PCIE register. That's it. That's the whole thing. No cap π«Ά
πΈ SYNOPSIS πΈ
ssize_t amdgpu_debugfs_regs_pcie64_write (struct file *f , const char
__user *buf , size_t size , loff_t *pos );
Look at her. A ssize_t return, four args, immaculate energy. She ate and left no crumbs β¨
π¦ ARGUMENTS π¦
fβ the open file handle. Like, the file you already have open. She's your main character π₯bufβ user buffer to write data from. This is where the bytes come from, bestie πsizeβ number of bytes to write. Math. Iconic π§posβ offset to seek to. Where in the register you're pulling up π

Quick reminder that's not from me, it's just the page: those names are copied exactly as they appear, so if you're grepping, type them exactly like that. No shortcuts π
And that's the whole page, bestie β no teasers, no filler, just amdgpu_debugfs_regs_pcie64_write doing her little 64-bit PCIE register write π
Sign-off time: this one came out of ./drivers/gpu/drm/amd/amdgpu, it's dated October 2026, and it answers to the name amdgpu_debug...pcie64_write(9). Take care of her ππ
