✨ drm_fb_xrgb8888_to_abgr8888(9) ✨

okay so bestie, this is a page from the Kernel API Manual, and it's literally about converting XRGB8888 into ABGR8888 in a clip buffer. it's giving "I make your pixels match your screen" energy and honestly? iconic. 💅

🌸 NAME 🌸

drm_fb_xrgb8888_to_abgr8888 — convert XRGB8888 to ABGR8888 clip buffer</p> 🎀

🦋 SYNOPSIS 🦋

void drm_fb_xrgb8888_to_abgr8888 (struct iosys_map *dst , const unsigned
int *dst_pitch , const struct iosys_map *src , const struct
drm_framebuffer *fb , const struct drm_rect *clip , struct
drm_format_conv_state *state );

like literally just call it with all six of those and you're slaying ✨

💖 ARGUMENTS 💖

  • dst — array of ABGR8888 destination buffers. yes, array, plural, we're fancy here 👑
  • dst_pitch — array of numbers of bytes between the start of two consecutive scanlines within dst. it can be NULL if the scanlines are stored right next to each other (bestie behavior fr fr) 🫶
  • src — array of XRGB8888 source buffer 🍓
  • fb — DRM framebuffer, the main character tbh 💀
  • clip — clip rectangle area to copy ✂️
  • state — transform and conversion state ✨

🌈 DESCRIPTION 🌈

so what this function does is copy parts of a framebuffer to display memory, and it converts the color format during the process. multitasking queen 💅

the parameters dst, dst_pitch and src refer to arrays. each array must have at least as many entries as there are planes in fb's format. each entry stores the value for the format's respective color plane at the same index — like little matching bestie slots 🎀

⚠️ heads up: this function does not apply clipping on dst — meaning the destination is at the top-left corner. no cap, that's just how it is 🙈

drivers can use this function for ABGR8888 devices that don't support XRGB8888 natively. it sets an opaque alpha channel as part of the conversion, so your transparency is fully handled, periodt 🌟

like a whole friend group of conversion functions, and every single one of them ate 🔥

and that's the whole page, bestie!! this one came from ./drivers/gpu/drm and it's dated October 2026 — manifesting good vibes and correctly-converted pixels for you forever 🧚💜 byeee!! 🦋
