struct globals (30 fields) source

TODO

almost everything here is RO after init.

I can clone these per-NUMA node and make backpointers via the per-core ‘struct core’ in the G segment register

AKA, split into global and rw_global

§ atomic_bool panicked

§ volatile enum bootstage current_bootstage

§ char *root_partition

§ struct vfs_mount *mount_list_head

TODO

no more list

§ struct vfs_node *root_node

§ struct block_device *root_node_disk

§ struct topology topology

§ size_t numa_node_count

§ struct numa_node *numa_nodes

§ atomic_size_t idle_core_count

§ size_t core_count

§ struct core **cores cc_counted_by(core_count)

§ struct scheduler **schedulers cc_counted_by(core_count)

§ struct dpc_cpu *dpc_data cc_counted_by(core_count)

§ atomic_size_t thread_count

§ size_t domain_count

TODO

We can consider migrating these to per-subsystem locations

§ struct domain **domains cc_counted_by(domain_count)

§ struct domain_buddy *domain_buddies

§ struct page *page_array

§ struct buddy_free_area buddy_free_area[BUDDY_MAX_ORDER]

§ struct scheduler_domain *scheduler_domains[TOPOLOGY_LEVEL_MAX]

§ vaddr_t hhdm_offset

§ atomic_uint64_t pt_epoch

§ uint64_t total_pages

§ pfn_t last_pfn

§ struct movealloc_callback_chain movealloc_chain

Per core workqueues
