Great!
What I am aware of at this moment is,
(some of the following can be covered by machine vector, though.)
- early setup before start_kernel()
Currently early_xen_setup() is directly called.
Eventually extending ia64 boot protocol would be necessary, though.
- Initialization hooks
struct pv_init_ops?
void (*arch_setup_early)(void)
void (*banner);
void (*pre_pasing_init)(void);
void (*post_pasing_init)(void);
void (*post_allocator_init)(void);
- irq hooks
struct pv_irq_ops
- init_IRQ(), irq_init()
- registering chip type
register_intr()
- assign_irq_vector()
- free_irq_vector()
- register_percpu_irq()
- send_ipi()
- resend_irq()
- IOSAPIC hooks
struct pv_iosapic_ops
- iosapic_init()
- iosapic_read()
- iosapic_write()
