💅 rivafb_load_cursor_image(9) 💅

okay so bestie, we're in the Kernel API Manual today and the star of the show is rivafb_load_cursor_image — the function whose whole entire job is loading a cursor image to hardware. yes, the little arrow thingy. she's iconic. 🖱️✨

🦋 NAME 🦋

rivafb_load_cursor_image — load cursor image to hardware

🌸 SYNOPSIS 🌸

void rivafb_load_cursor_image (struct riva_par *par , u8 *data8 , u16 bg
, u16 fg , u32 w , u32 h );

like, that's the whole signature. short queen. 👑

🎀 ARGUMENTS 🎀

  • par — pointer to private data. yup, the private data. give her the pointer and she'll handle it. 🫶
  • data8 — address to monochrome bitmap (1 = foreground color, 0 = background). it's giving minimalist. black and white. two moods only. 🖤🤍
  • bg — background color (ARGB1555) — heads up, the alpha bit determines opacity. so the alpha bit is literally the vibe check for transparency. 💀
  • fg — foreground color (ARGB1555). the main character color, ngl. ✨
  • w — width of cursor image in pixels. 📏
  • h — height of cursor image in scanlines. 📐

💖 DESCRIPTION 💖

so what she does: loads the cursor image based on a monochrome source and mask bitmap. the image bits decide the color of the pixel — 0 for background, 1 for foreground. periodt. simple as that. 🎯

and the lowkey best part? only the affected region (as determined by the w and h parameters) gets updated. no cap, she's not out here redrawing the whole screen. efficient icon. 🔥

CALLED FROM: rivafb_cursor — that's her caller, that's her origin story. iykyk. 💫

🌈 SEE ALSO 🌈

kernel file ./drivers/video/fbdev/riva/fbdev.c — go read it bestie, it's right there. 📖

then the whole squad, fr fr:

ok that's the whole page, no notes. cursor loaded, facts intact, vibe immaculate. 💅🦋
