📦 version 7.3.1, in nixpkgs unstable

💖 vsp1_isp_get_bus_master(9) 💖

okay so bestie, this is a page from the Kernel API Manual — yes, the vsp1_isp_get_bus_master(9) one, we're doing kernel driver lore today and honestly? it's giving backstage pass energy 🎟️✨

🌸 NAME 🌸

vsp1_isp_get_bus_master — get the VSPX bus master, that's the whole vibe 🫶

✨ SYNOPSIS ✨

struct device * vsp1_isp_get_bus_master (struct device *dev );

🎀 ARGUMENTS 🎀

  • dev — the VSP1 struct device, like the main character of this whole situation 👑

🦋 DESCRIPTION 🦋

so here's the tea, bestie ☕ — the VSPX doesn't just raw-dog memory access on its own. nope. it goes through an FCPX instance, like FCPX is its plug 🔌 periodt.

which means: when you're allocating memory buffers that the VSPX is gonna have to access, you should be using the struct device of the FCPX, not just whatever device you had lying around. lowkey important, ngl 🙈

and that's literally what this function is for — call it to get a reference to that device. that's it. that's the function. iconic behavior honestly 💅

⭐ RETURN ⭐

a pointer to the bus master's device 🫡✨ — struct device *, right back at ya.

🌈 SEE ALSO 🌈

kernel file ./drivers/media/platform/renesas/vsp1/vsp1_vspx.c — go read it, iykyk 📖

and the whole friend group:

like a whole squad of vsp1_isp_* functions, no cap 🔥

ngl this one's short and sweet — grab the FCPX device, hand it to the VSPX, let it cook. main character energy from start to finish 🧚‍♀️💜

okay and lastly, the boring-but-required sign-off so we don't get in trouble 😭: this page came from ./drivers/media/platform/renes... and it's dated October 2026, footer reads vsp1_isp_get_bus_master(9) 💖 that's the whole page, slay, bye bestie 🎀✨
