No Andrew, It is not for debugging.
I wanted to develop some application which should be triggered after change in
memory content.
But to know that memory content is changed I wanted to take UEFI help.
In this case is there any feature which can notify me about memory change ?
No. Best you can do is have a timer event that watches the event and have that
event signal your driver.
Thanks Andrew for timer approach. But pooling memory location will consume CPU
cycles. Is there any ACPI feature which can help me in this ?

Hi All,
I have certain requirement as stated below. Please help me how I can solve this
situation.
I wanted some notifier which can tell me that some memory is changes.
I don’t want to poll that memory location. Please tell me if there is any
nearby solution.
Are you debugging? You may be able to use the X86 debug registers (often called
watchpoints in a debugger).
Thanks,
Andrew Fish
