STRUCT XE_PXP_GSC_CLIENT_RESOURCES(9)

💅 struct xe_pxp_gsc_client_resources (9) — Kernel API Manual

okay so bestie, we're in the Kernel API Manual and this is literally the page for struct xe_pxp_gsc_client_resources, no cap. 🎀

---

✨ NAME ✨

struct xe_pxp_gsc_client_resources — the resources for GSC submission by a PXP client. And like, the GSC FW supports multiple GSC clients active at the same time, so this is very much a "you're not the only one in the group chat" situation. 🫶

---

🌸 SYNOPSIS 🌸

struct xe_pxp_gsc_client_resources {
    u64 host_session_handle;
    struct xe_vm *vm;
    struct xe_exec_queue *q;
    struct xe_bo *bo;
    u32 inout_size;
    struct iosys_map batch;
    struct iosys_map msg_in;
    struct iosys_map msg_out;
 };

like, that's the whole vibe right there 💖

👑 Members 👑

• host_session_handle — the handle that identifies the client in messages sent to the GSC firmware. it's giving ✨nametag at the party✨ iykyk.
• vm — the VM used for PXP submissions to the GSCCS. yes, GSCCS, write it down 📝
• q — the GSCCS exec queue for PXP submissions. this is the queue, bestie, it does the queueing 💅
• bo — the BO used for submissions to the GSCCS and GSC FW. it includes space for the GSCCS batch and the input/output buffers read/written by the FW. so it's like the tote bag that carries literally everything 👜✨
• inout_size — the size of each of the msg_in/out sections individually. individually!! each one!! per section!! okay periodt 💀
• batch — the iosys_map to the batch memory within the BO. it's inside the BO, bestie, remember that 🌈
• msg_in — the iosys_map to the input memory within the BO. input. in. going in. 🔥
• msg_out — the iosys_map to the output memory within the BO. output. out. coming out. ⭐

💀 real talk: those iosys_map members are literal maps into the same BO, so like… don't get it twisted, they're not three separate buffers. that's the whole point of the bo field. 🧚

okay that's the page!! this one came from ./drivers/gpu/drm/xe in October 2026, so shoutout to the kernel docs crew for timestamping the vibes 🌸💜 and ty for reading bestie, ily, go write some PXP submissions 🎀✨
