STRUCT RCAR_ISP_CORE_IO(9)

💅 struct rcar_isp_core_io — the Kernel API Manual moment

okay so bestie, this is a page about struct rcar_isp_core_io, from the Kernel API Manual (section 9, kernel internals, you know the vibe). It's literally the info bundle for an IO video device. One struct. Nine fields. All of them slay. Let's go. ✨

🌸 SYNOPSIS 🌸

struct rcar_isp_core_io {
    struct rcar_isp_core *core;
    struct mutex lock;
    struct video_device vdev;
    struct media_pad pad;
    struct vb2_queue queue;
    bool streaming;
    struct list_head buffers;
    struct v4l2_format format;
};

no cap, that's the whole shape of it — copy it exactly if you're writing it out, i'm not about to let you typo your way through this 🫶

👑 MEMBERS 👑

• core — the backlink to the common ISP core structure. it's giving "this device knows its parent" and honestly iconic for it 💖
• lock — the struct mutex that protects vdev, pad and queue, plus the open/close fops. so like, the bodyguard of the whole struct. respect her 🌈
• vdev — the V4L2 video device that's associated with this IO port. main character energy fr fr 🎀
• pad — the media pad for vdev. yes, that's for vdev specifically, don't come for me 💀
• queue — the VB2 buffers queue for $vdev. the queue. for $vdev. iykyk ✨
• streaming — a bool flag that says whether the device is streaming… or not. that's it. that's the whole field. she's simple, she's honest, we love her 💅
• buffers — the list of buffers that have been queued to the device. keeping track of everyone, lowkey a little nosy but we stan 🦋
• format — the active V4L2 format. the one currently running the show 👑

💜 SEE ALSO 💜

lowkey you gotta peek at the kernel file for this one:

./drivers/media/platform/renesas/rcar-isp/risp-core.h

and while you're in the neighborhood, go say hi to these besties:

• struct risp_buffer(9)
• struct rcar_isp_job(9)
• struct rcar_isp_vspx(9)
• struct rcar_isp_core(9)

all of them matter, all of them are linked, do not skip a single one or i will know 🙈

warning bestie: that source path and those struct names are literal. type them wrong and the kernel will simply not have a good time. consider this your gentle vibe check 💀

mwah, that's the whole page 🎀 sign-off time: this one comes out of ./drivers/media/platform/renes... (the source/version bit, yeah it's abbreviated on the original page too, not me being lazy), dated October 2026, and it's filed under struct rcar_isp_core_io(9). periodt. 💖✨🌸
