[求助]内核堆栈的个数
[QUOTE=magicfound;614529]参考 http://bbs.pediy.com/showthread.php?t=60247 我用windbg看到是:不同的进程在陷入内核时SS 和 ESP 初始化是一样。但还是没有弄明白同一个进程中不同的线程,在同时进行系统调用的时候如何处理的?[/QUOTE] 系统调用、中断、异常进入内核时的内核栈是由TSS中的ESP0指定的,这是CPU权限切换的硬件机制决定的,ESP0就是当前线程的内核栈基址。当线程切换时TSS->ESP0也同时被改变(TSS中的其它字段基本不变,如SS)。线程被切换后的内核栈基址和SP指针都保存在_KTHREAD结构中! |

[求助] lock cmpxchg [edx], ecx 做的什么操作?
CMPXCHG - Compare and Exchange 0F B0/ r CMPXCHG r/m8,r8 Compare AL with r/m8. If equal, ZF is set and r8 is loaded into r/m8. Else, clear ZF and load r/m8 into AL. 0F B1/ r CMPXCHG r/m16,r16 Compare AX with r/m16. If equal, ZF is set and r16 is loaded into r/m16. Else, clear ZF and load r/m16 into AL 0F B1/ r CMPXCHG r/m32,r32 Compare EAX with r/m32. If equal, ZF is set and r32 is loaded into r/m32. Else, clear ZF and load r/m32 into AL Description Compares the value in the AL, AX, or EAX register (depending on the size of the operand) with the first operand (destination operand). If the two values are equal, the second operand (source operand) is loaded into the destination operand. Otherwise, the destination operand is loaded into the AL, AX, or EAX register. This instruction can be used with a LOCK prefix to allow the instruction to be executed atomi-cally. To simplify the interface to the processor's bus, the destination operand receives a write cycle without regard to the result of the comparison. The destination operand is written back if the comparison fails; otherwise, the source operand is written into the destination. (The processor never produces a locked read without also producing a locked write.) 没有对应高级语言 |
