STRUCT PVR_HWRT_DATA(9)

🦋 struct pvr_hwrt_data(9) — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual entry for struct pvr_hwrt_data ✨ this is the page you want if you're poking at the Imagination GPU driver's HWRT stuff, and honestly? it's giving "small struct, big responsibilities" 💅

🌸 NAME 🌸

struct pvr_hwrt_data — the structure that represents HWRT data 🎀 no cap, that's literally what it is.

✨ SYNOPSIS ✨

here's the glow-up, bestie — the struct in all its glory, copied exactly so you don't have to squint at anything:

struct pvr_hwrt_data {
    struct pvr_fw_object *fw_obj;
    struct rogue_fwif_hwrtdata data;
    struct list_head freelist_node;
    struct pvr_fw_object *srtc_obj;
    struct pvr_fw_object *raa_obj;
    struct pvr_hwrt_dataset *hwrt_dataset;
 };

🫶 Members 🫶

time for the member-by-member tour, and yes we're doing all of them because every single field is a main character here 👑

• fw_obj — the FW object that represents the FW-side structure. it's the firmware's copy of the situation, basically 🦋
• data — your local copy of that FW-side structure. homegirl keeps her own notes, periodt 💅
• freelist_node — the list node that connects this HWRT to the local freelist. it's the little string tying this struct into the group chat that is the freelist 🎀
• srtc_obj — the FW object representing the shadow render target cache. heads up though: this one is only valid if max_rts > 1 👀
• raa_obj — the FW object representing the renders accumulation array. and same energy: only valid if max_rts > 1 🙈
• hwrt_dataset — a back pointer to the owning HWRT dataset. it knows where it came from, we love an icon with roots 🌈
