STRUCT MINIDUMP_SUBSYSTEM(9)

🌈 struct minidump_subsystem(9) 🌈

okay so this is a Kernel API Manual page, and it's literally the dedicated glow-up for struct minidump_subsystem — the subsystem's SMEM Table of content. bestie, it's giving kernel-struct realness, and we're gonna walk through every member like a group-chat recap. 💖

🦋 NAME 🦋

struct minidump_subsystem — Subsystem's SMEM Table of content

✨ SYNOPSIS ✨

here's the exact struct, no cap — every field where it belongs:

       struct minidump_subsystem {
           __le32 status;
           __le32 enabled;
           __le32 encryption_status;
           __le32 encryption_required;
           __le32 region_count;
           __le64 regions_baseptr;
        };

👑 Members 👑

one by one, here's the cast of fields — all iconic, all necessary:

• status — Subsystem toc init status. like, the init-status vibe check for this subsystem's table of contents.
• enabled — if set to 1, this region would be copied during coredump. so yeah, 1 is the copy-me-during-coredump setting.
• encryption_status — Encryption status for this subsystem. the encryption-status gossip, but for this subsystem.
• encryption_required — Decides to encrypt the subsystem regions or not. it literally makes that call.
• region_count — Number of regions added in this subsystem toc. count 'em up.
• regions_baseptr — regions base pointer of the subsystem. periodt.
