v4l2_valid_dv_timings(9)

✨ v4l2_valid_dv_timings ✨

okay bestie, real talk — welcome to the v4l2_valid_dv_timings page from the Kernel API Manual 💅 this one's short and sweet and it does exactly what it says on the tin: it tells you whether some timings are valid. no cap. let's get into it 🎀

🌸 SYNOPSIS 🌸

bool v4l2_valid_dv_timings (const struct v4l2_dv_timings *t , const
struct v4l2_dv_timings_cap *cap , v4l2_check_dv_timings_fnc fnc , void
*fnc_handle );

she returns a bool, she takes four things, she's iconic like that 🫶

🦋 ARGUMENTS 🦋

• t — the v4l2_dv_timings struct. this is the timings you're asking about, the main character of the whole operation 👑
• cap — the v4l2_dv_timings_cap capabilities. basically the hardware's vibe check — what it can and can't handle ✨
• fnc — callback to check if this timing is OK. it may be NULL. ngl, lowkey optional, but highkey useful if you got extra rules 💅
• fnc_handle — a handle that is passed on to fnc. it just... gets handed over. that's the whole job. respect 🫡

💖 DESCRIPTION 💖

so here's the tea ☕ — this function returns true if the given dv_timings struct is supported by the hardware capabilities and the callback function (if it's non-NULL). if either one says nah, you get false. periodt 💀

literally that's it, she's a simple girl with a simple purpose and she ate 🔥
