在ARM的内核oops中跟踪日志打印在内核日志中 -
<1>[ 4205.112835] I[0:swapper/0:0] [c0] Unable to handle kernel paging request at virtual address ff898580
<1>[ 4205.112874] I[0:swapper/0:0] [c0] pgd = ec3c4000
<1>[ 4205.112901] I[0:swapper/0:0] [c0] [ff898580] *pgd=00000000
<0>[ 4205.112939] I[0:swapper/0:0] [c0] Internal error: Oops: 80000005 #1] PREEMPT SMP ARM
有时这个代码是oops -
Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP ARM
它在大多数日志中是 -
Internal error: Oops: 5 [#1] PREEMPT SMP ARM
有人可以解释这段代码的用途及其含义吗？
