返回类型：void

参数：

类型	参数	名称
struct mce *	m
struct mce *	final
unsigned long *	toclear
unsigned long *	valid_banks
int	no_way_out
int *	worst

__clear_bit - Clears a bit in memory*@nr: the bit to clear*@addr: the address to start counting from* Unlike clear_bit(), this function is non-atomic. If it is called on the same* region of memory concurrently, the effect may be that only one operation

1159

如果非st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则继续下一循环

1162

如果非 subevents to enable 则继续下一循环

1165

Bank's MCi_MISC MSR 等于0

1166

Bank's MCi_ADDR MSR 等于0

1167

Machine check bank reporting the error 等于i

1169

Bank's MCi_STATUS MSR 等于MSR access wrappers used for error injection

1170

如果非Bank's MCi_STATUS MSR 按位与valid error 的值则继续下一循环

1177

如果非Bank's MCi_STATUS MSR 按位与如果ser则Signaled machine check 否则uncorrected error 的值且非no_way_out则继续下一循环

1182

add_taint(TAINT_MACHINE_CHECK, LOCKDEP_NOW_UNRELIABLE)

1184

severity等于mce_severity(m, tolerant, NULL, true)

1190

如果severity恒等于MCE_KEEP_SEVERITY或severity恒等于MCE_UCNA_SEVERITY的值且非no_way_out则继续下一循环

1194

__set_bit - Set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* Unlike set_bit(), this function is non-atomic. If it is called on the same* region of memory concurrently, the effect may be that only one operation* succeeds.

1197

如果severity恒等于MCE_NO_SEVERITY则继续下一循环

1200

Read ADDR and MISC registers.

1203

Error severity 等于severity

1205

mce_log(m)

1207

如果severity大于worst则

1208

final等于m

1209

worst等于severity

名称	描述
do_machine_check	The actual machine check handler. This only handles real* exceptions when something got corrupted coming in through int 18.* This is executed in NMI context not subject to normal locking rules. This* implies that most kernel services cannot be safely used
