STRUCT HANTRO_VARIANT(9)

💅 struct hantro_variant(9) 💅

hey bestie!! welcome to the Kernel API Manual page for struct hantro_variant(9) — the little info card that gives you information about VPU hardware variant. no cap, it’s giving hardware-variant lore and we’re here for it. 🫶

🎀 NAME 🎀

struct hantro_variant — information about VPU hardware variant. that’s the whole vibe: this struct is the info card for the VPU hardware variant. ✨

🌸 SYNOPSIS 🌸

struct hantro_variant {
    unsigned int enc_offset;
    unsigned int dec_offset;
    const struct hantro_fmt *enc_fmts;
    unsigned int num_enc_fmts;
    const struct hantro_fmt *dec_fmts;
    unsigned int num_dec_fmts;
    const struct hantro_fmt *postproc_fmts;
    unsigned int num_postproc_fmts;
    const struct hantro_postproc_ops *postproc_ops;
    unsigned int codec;
    const struct hantro_codec_ops *codec_ops;
    int (*init)(struct hantro_dev *vpu);
    int (*runtime_resume)(struct hantro_dev *vpu);
    const struct hantro_irq *irqs;
    int num_irqs;
    const char * const *clk_names;
    int num_clocks;
    const char * const *reg_names;
    int num_regs;
    unsigned int double_buffer : 1;
    unsigned int legacy_regs : 1;
    unsigned int late_postproc : 1;
    const struct of_device_id *shared_devices;
};

okay now the glow-up tour of every single member, bestie — nothing skipped, periodt: 💅

🫶 Members 🫶

• enc_offset — offset from VPU base to encoder registers. it’s the encoder’s little address home. 🎀
• dec_offset — offset from VPU base to decoder registers. decoder address energy. 🦋
• enc_fmts — encoder formats. the encoder’s format lineup. ✨
• num_enc_fmts — number of encoder formats. literally the count for enc_fmts. 🔢
• dec_fmts — decoder formats. the decoder’s format lineup. 🌸
• num_dec_fmts — number of decoder formats. the count for dec_fmts. 🔢
• postproc_fmts — post-processor formats. post-processor format lineup, slay. 💖
• num_postproc_fmts — number of post-processor formats. the count for postproc_fmts. 🔢
• postproc_ops — post-processor ops. the post-processor’s ops. 🛠️
• codec — supported codecs. that’s the codec support field. 👑
• codec_ops — codec ops. codec operation energy. 🔥
• init — initialize hardware, optional. optional, so don’t assume it’s always there. 🙈
• runtime_resume — reenable hardware after power gating, optional. also optional, bestie. ⚡
• irqs — array of irq names and interrupt handlers. interrupt-handler array vibes. 💀
• num_irqs — number of irqs in the array. the count for irqs. 🔢
• clk_names — array of clock names. clock-name array energy. 🕰️
• num_clocks — number of clocks in the array. the count for clk_names. 🔢
• reg_names — array of register range names. register-range-name array. 🗂️
• num_regs — number of register range names in the array. the count for reg_names. 🔢
• double_buffer — core needs double buffering. the core said double-buffer era. 🎀
• legacy_regs — core uses legacy register set. legacy register set, noted. 🧚
• late_postproc — postproc must be set up at the end of the job. setup happens at the end, periodt. ⏰
• shared_devices — an array of device ids that cannot run concurrently. they cannot run concurrently, no cap. 🚫
