STRUCT IMG_IR_PRIV_HW(9)

🌸 NAME 🌸

hey bestie, welcome to the struct img_ir_priv_hw(9) page from the Kernel API Manual — this is literally the private driver data for the hardware decoder, and we're gonna make it make sense. 💅✨

struct img_ir_priv_hw — private driver data for hardware decoder. No cap, that's the whole assignment. 🫶

✨ SYNOPSIS ✨

okay so here's the struct in all its glory, copied exactly because we do not mess with code, periodt:

       struct img_ir_priv_hw {
           unsigned int                    ct_quirks[4];
           struct rc_dev                   *rdev;
           struct notifier_block           clk_nb;
           struct timer_list               end_timer;
           struct timer_list               suspend_timer;
           const struct img_ir_decoder     *decoder;
           u64 enabled_protocols;
           unsigned long                   clk_hz;
           struct img_ir_reg_timings       reg_timings;
           unsigned int                    flags;
           struct img_ir_filter            filters[RC_FILTER_MAX];
           enum img_ir_mode                mode;
           bool stopping;
           u32 suspend_irqen;
           u32 quirk_suspend_irq;
        };

💖 Members 💖

these are the little fields that make the whole struct iconic — every single one matters, fr fr:

• ct_quirks — quirk bits for each code type. lowkey the chaos gremlins of the code-type world. 🌀
• rdev — the remote control device. the main character device, honestly. 👑
• clk_nb — notifier block for clock notify events. it's giving "clock gossip" energy. ⏰
• end_timer — timer until repeat timeout. the countdown queen. ⏳
• suspend_timer — timer to re-enable protocol. she wakes the protocol back up after suspend. 😴➡️😎
• decoder — current decoder settings. the decoder's current fit. 🎀
• enabled_protocols — currently enabled protocols. these are the protocols that are switched on rn. ✅
• clk_hz — current core clock rate in Hz. numbers bestie, numbers. 🔢
• reg_timings — timing reg values for decoder at clock rate. all the timing-register tea at this clock rate. ⚙️
• flags — IMG_IR_F_*. literally those flag bits, exactly like that. 🚩
• filters — HW filters (derived from scancode filters). hardware filters that come from scancode filters. 💅
• mode — current decode mode. what mode are we in? this one. 🦋
• stopping — indicates that decoder is being taken down and timers should not be restarted. bestie, this is important: timers must not restart here. 😭
• suspend_irqen — saved IRQ enable mask over suspend. the IRQ enable mask that got saved across suspend. 💾
• quirk_suspend_irq — saved IRQ enable mask over quirk suspend timer. same saved-mask vibe, but for the quirk suspend timer. 🫶
