STRUCT AMVDEC_CORE(9)

🌸 NAME 🌸

okay bestie, welcome to struct amvdec_core(9) from the Kernel API Manual — yes, we're doing kernel structs and we're gonna slay. struct amvdec_core — device parameters, singleton. it's giving the one-and-only holding spot for device params, and honestly? iconic.

✨ SYNOPSIS ✨

here's the struct in all its glory, exact and unbothered:

       struct amvdec_core {
           void __iomem *dos_base;
           void __iomem *esparser_base;
           struct regmap *regmap_ao;
           struct device *dev;
           struct device *dev_dec;
           const struct vdec_platform *platform;
           struct meson_canvas *canvas;
           struct clk *dos_parser_clk;
           struct clk *dos_clk;
           struct clk *vdec_1_clk;
           struct clk *vdec_hevc_clk;
           struct clk *vdec_hevcf_clk;
           struct reset_control *esparser_reset;
           struct video_device *vdev_dec;
           struct v4l2_device v4l2_dev;
           struct amvdec_session *cur_sess;
           struct mutex lock;
        };

💅 Members 💅

member-by-member vibe check, no skips:

• dos_base — DOS memory base address. that's the DOS memory base address, periodt.
• esparser_base — PARSER memory base address. the PARSER memory base address, slay.
• regmap_ao — regmap for the AO bus. we love an AO-bus regmap.
• dev — core device. main character energy.
• dev_dec — decoder device. its decoder bestie.
• platform — platform-specific data. very platform-specific.
• canvas — canvas provider reference. art-class reference, cute.
• dos_parser_clk — DOS_PARSER clock. clock check: passed.
• dos_clk — DOS clock. another clock, obsessed.
• vdec_1_clk — VDEC_1 clock. yes bestie, VDEC_1.
• vdec_hevc_clk — VDEC_HEVC clock. HEVC clock representation.
• vdec_hevcf_clk — VDEC_HEVCF clock. and the HEVCF one too.
• esparser_reset — RESET for the PARSER. RESET for the PARSER, literally.
• vdev_dec — video device for the decoder. video device for the decoder, no cap.
• v4l2_dev — v4l2 device. v4l2 device, iconic.
• cur_sess — current decoding session. the current decoding session.
• lock — video device lock. video device lock, keep it safe.
