Detailed Description

Shared state of the dump file object.

This structure describes the data portion of the dump file object, which can be shared by many kdump_ctx_t objects.

Field Documentation

◆ arch

enum kdump_arch kdump_shared::arch

Internal-only arch index.

◆ arch_init_done

int kdump_shared::arch_init_done

Non-zero if arch init has been called.

◆ arch_ops

const struct arch_ops* kdump_shared::arch_ops

Arch-specific operations.

◆ archdata

void* kdump_shared::archdata
