s3c_fb_disable_irq(9)

💅 s3c_fb_disable_irq — bestie, let's talk about it

Okay so first things first, this is a page from the Kernel API Manual, section 9 (that's the kernel dev section, iykyk 🧚). The star of the show? s3c_fb_disable_irq(9) — literally the function that turns off your framebuffer interrupts. No cap, that's the whole vibe.

🌸 NAME 🌸

s3c_fb_disable_irq — okay so this bad boy's job is to disable framebuffer interrupts. That's it. That's the whole personality. It's the "shut it down" bestie of the s3c framebuffer world, and honestly? Iconic. 🔥

---

✨ SYNOPSIS ✨

void s3c_fb_disable_irq (struct s3c_fb *sfb );

Yeah bestie, that's a void return — no little treat coming back from this one, it just does the thing and dips. 🫶

---

🎀 ARGUMENTS 🎀

• sfb — main hardware state. This is the big one, the main character energy struct that holds all the juicy hardware state. You hand it over and it handles the rest. 💖

🦋 SEE ALSO 🦋

Okay so if you're obsessed (and you should be), go check out the kernel file ./drivers/video/fbdev/s3c-fb.c — that's where all the magic actually lives, fr fr. And while you're there, say hi to all these:

struct s3c_fb_variant(9), struct s3c_fb_win_variant(9), struct s3c_fb_driverdata(9), struct s3c_fb_palette(9), struct s3c_fb_win(9), struct s3c_fb_vsync(9), struct s3c_fb(9), s3c_fb_validate_win_bpp(9), s3c_fb_check_var(9), s3c_fb_calc_pixclk(9), s3c_fb_align_word(9), vidosd_set_size(9), vidosd_set_alpha(9), shadow_protect_win(9), s3c_fb_enable(9), s3c_fb_set_par(9), s3c_fb_update_palette(9), s3c_fb_setcolreg(9), s3c_fb_blank(9), s3c_fb_pan_display(9), s3c_fb_enable_irq(9), s3c_fb_wait_for_vsync(9), s3c_fb_missing_pixclock(9), s3c_fb_alloc_memory(9), s3c_fb_free_memory(9), s3c_fb_release_win(9), s3c_fb_probe_win(9), s3c_fb_set_rgb_timing(9), s3c_fb_clear_win(9), s3c_fb_remove(9)

That's a whole friend group right there and they're all linked, so go down the rabbit hole, bestie. 🐇✨

Side note: s3c_fb_enable_irq(9) is literally the sibling of this function — it turns interrupts on while this one turns 'em off. They're giving opposites-attract, and I love that for them. 💀

✨ okay that's a wrap on the s3c_fb_disable_irq lore ✨

This little gem lives in ./drivers/video/fbdev (the source), and the page itself is dated October 2026. Slay, stay interrupting (or don't, actually — that's the point), and see you in the next man page. 💜🎀🌈
