💅 vpif_channel_isr — ISR handler for vpif capture

okay so bestie, welcome to the Kernel API Manual ✨ this page is literally all about one interrupt handler and honestly? she's kind of the main character of the capture pipeline 🎀

🌸 NAME 🌸

vpif_channel_isr — the ISR handler for vpif capture 🦋

like, the interrupt service routine. the one who answers when the hardware knocks. no cap.

⭐ SYNOPSIS ⭐

irqreturn_t vpif_channel_isr (int irq , void *dev_id );

that's it. that's the whole signature. she's compact, she's iconic 💅

🎀 ARGUMENTS 🎀

  • irq — the irq number 🔥 that's the interrupt line calling in, fr fr
  • dev_id — a dev_id ptr 🫶 the classic dev_id pointer, doing its lil pointer thing

✨ DESCRIPTION ✨

okay so here's the vibe: this handler changes the status of the captured buffer 💖 then it takes the next buffer from the queue 🌈 and then it sets that buffer's address in the VPIF registers 👑

so it's giving "finish the current one, grab the next one, tell the hardware where it lives." three steps. all slay. periodt 🧚

🦋 SEE ALSO 🦋

the kernel file is ./drivers/media/platform/ti/davinci/vpif_capture.c — that's where the lore lives 📖 and then there is a whole friend group of related functions, so let's do a roll call 😭

every single one of them, accounted for, not a single one left on read 💀💖

ngl the whole davinci vpif capture squad is in that list, so if you're lost, just start clicking through the (9) pages. iykyk 🍓

and that's the page!! 🌸 this lil sign-off comes courtesy of the source path ./drivers/media/platform/ti/da... and she's dated October 2026 — so mark your calendar bestie, the vpif_channel_isr(9) era is upon us 👑💜
