okay so this is a page straight out of the Kernel API Manual, section 9, and it's all about vmw_bo_cpu_blit_line — yes that's a mouthful, we're gonna say it with our chest 🫶

✨ NAME ✨

vmw_bo_cpu_blit_line — blit part of a line from one bo to another. that's it, that's the whole vibe 💫

🎀 SYNOPSIS 🎀

int vmw_bo_cpu_blit_line (struct vmw_bo_blit_line_data *d , u32
dst_offset , u32 src_offset , u32 bytes_to_copy );

🌸 ARGUMENTS 🌸

• d — the blit data, as described above. like, above above. you know the one 👀
• dst_offset — where the copy starts in the destination, counted from the start of the bo. that's the offset bestie ✨
• src_offset — where the copy starts in the source, counted from the start of the bo. same deal, other side 🦋
• bytes_to_copy — how many bytes we're copying in this line. the actual amount. no cap 💅
