trigger I assumed some code in the kernel modified the memory and user debugging could not pick it up. I then broke into kernel mode so that I could set a breakpoint on access for the same user mode virtual memory address. My problem is I don’t know how to do that. I’ve done t...

In its strict sense, we are not going to set a breakpoint, but what we do can be used as a breakpoint, since we are making the debugger break on certain conditions which we can control. What we will do is to change the access flag of memory pages, from PAGE_EXECUTE_* ...
内核调试过程中,bp, bu, bm (Set Breakpoint)和ba (Break on Access)命令会影响多处理器电脑上的所有处理器。 例如,如果当前有 3 个处理器,可以通过下面的命令在SomeAddress设置断点。 1: kd>bp SomeAddress 任何处理器(不单是处理器 1)执行到该地址都将引起断点陷阱(breakpoint trap)。
· 你可以使用bl(“Breakpoint List”)查看所有已设置的断点: kd> bl 0e [d:\winddk\3790\src\general\ioctl\sys\sioctl.c @ 123] 0001 (0001) SIoctl!DriverEntry 1e [d:\winddk\3790\src\general\ioctl\sys\sioctl.c @ 338] 0001 (0001)Sioctl!SioctlDeviceControl+0x103 ...

memory is accessed (for read, write or execute operation). This breakpoint type uses special debug CPU registers: DR0, DR1, DR2, DR3 for linear addresses to stop on, and DR6, DR7 - for debug flags. So in total it's possible to set up only 4 access breakpoints at the same time...
