Field Documentation

int active

Definition at line 80 of file cpu.h.

cpu_arch_t arch

Definition at line 86 of file cpu.h.

__u32 delay_loop_const

Definition at line 84 of file cpu.h.

thread_t* fpu_owner

Definition at line 88 of file cpu.h. Referenced by thread_destroy().

__u16 frequency_mhz

Definition at line 83 of file cpu.h.

int id

Processor ID assigned by kernel. Definition at line 78 of file cpu.h.

count_t missed_clock_ticks

When system clock loses a tick, it is recorded here so that clock() can react. This variable is CPU-local and can be only accessed when interrupts are disabled. Definition at line 70 of file cpu.h.

volatile count_t needs_relink

Definition at line 65 of file cpu.h.

atomic_t nrdy

Definition at line 63 of file cpu.h. Referenced by kcpulb(), and thread_ready().

runq_t rq[RQ_COUNT]

Definition at line 64 of file cpu.h. Referenced by kcpulb(), and thread_ready().

context_t saved_context

Definition at line 61 of file cpu.h.

__u8* stack

Stack used by scheduler when there is no running thread. Definition at line 93 of file cpu.h.

link_t timeout_active_head

Definition at line 68 of file cpu.h. Referenced by timeout_unregister().

int tlb_active
