STRUCT PVR_MMU_OP_CONTEXT(9)

🎀 struct pvr_mmu_op_context(9) 🎀

okay bestie, welcome to the Kernel API Manual entry for struct pvr_mmu_op_context. This is literally the context holding data for individual device-virtual mapping operations. Intended for use with a VM bind operation. no cap. 💖

🌸 NAME 🌸

struct pvr_mmu_op_context — context holding data for individual device-virtual mapping operations. Intended for use with a VM bind operation. ✨

🦋 SYNOPSIS 🦋

here's the struct in all its glory, bestie — keep it exact:

       struct pvr_mmu_op_context {
           struct pvr_mmu_context *mmu_ctx;
           struct {
             struct sg_table *sgt;
             u64 sgt_offset;
             struct pvr_page_table_l1 *l1_prealloc_tables;
             struct pvr_page_table_l0 *l0_prealloc_tables;
           } map;
           struct {
             struct pvr_page_table_l1 *l1_free_tables;
             struct pvr_page_table_l0 *l0_free_tables;
           } unmap;
           struct pvr_page_table_ptr curr_page;
           enum pvr_mmu_sync_level sync_level_required;
        };

🫶 Members 🫶

okay so the top-level members are giving main character energy:

• mmu_ctx — the MMU context associated with the owning VM context. 🫶
• map — data specifically for map operations. 🗺️
• unmap — data specifically for unmap operations. 🧽
• curr_page — a reference to a single physical page as indexed by the page table structure. 📄
• sync_level_required — the maximum level of the page table tree structure which has (possibly) been modified since it was last flushed to the device. 🚦

⚠️ this field should only be set with pvr_mmu_op_context_require_sync or indirectly by pvr_mmu_op_context_sync_partial. no cap.
