Redhat-devel-list:
Hi ,everybody , I have a question .
In the source code in head.S ?
#define CPU_PARAMS SYMBOL_NAME(boot_cpu_data)
!!! SYMBOL_NAME(boot_cpu_data) <---> boot_cpu_data
#define X86 CPU_PARAMS+0
#define X86_VENDOR CPU_PARAMS+1
#define X86_MODEL CPU_PARAMS+2
#define X86_MASK CPU_PARAMS+3
#define X86_HARD_MATH CPU_PARAMS+6
#define X86_CPUID CPU_PARAMS+8
#define X86_CAPABILITY CPU_PARAMS+12
#define X86_MMU_CR4 CPU_PARAMS+16
#define X86_VENDOR_ID CPU_PARAMS+20
I think boot_cpu_data should be a struct .
But can those define a struct using C systax?
BTW ,what is the use of CR4 register in i386 cpu ?
Thank you all
