vb2_plane_size(9)

✨ NAME ✨

welcome to the Kernel API Manual, bestie — the page is vb2_plane_size(9) and she is literally here to do one thing: vb2_plane_size — return plane size in bytes. That's the whole main-character moment, no cap 💅✨. The way it just returns plane size in bytes? iconic.

🦋 SYNOPSIS 🦋

the signature is exactly this, character for character, don't @ me:

unsigned long vb2_plane_size (struct vb2_buffer *vb , unsigned int
plane_no );

lowkey just a vibe check of the signature, but make no mistake: vb is the buffer, plane_no is which plane, and the return type is unsigned long — the plane size in bytes, periodt 🫶.

💅 ARGUMENTS 💅

• vb — pointer to struct vb2_buffer to which the plane in question belongs to. Like, the buffer that owns the plane, iykyk 🫶.
• plane_no — plane number for which size should be returned. You're asking about that specific plane, and she's giving you the size ✨.
