So once we have requested the memory, how did we access, in case of what you do remember, after we
call the question Scholem region?
How do we access the ports?
Registers.
In case of Almaden, are you on board my bail once we call request region?
We have a request of the region, but how to access the ports?
We have some functions in B, the NBN or other functions where to access the port registers.
Evidence in case of memory were saying that we can directly access them because it is my money.
So can we access memory, my memory directly?
No, we cannot, because memory mapped out those addresses, our physical addresses.
Last kernel is running.
In this case, all the addresses which is accessing is what addresses.
So like userspace can Alexis's memory to people's.
So when Connecticut needs to access memory maps and devices, it has to first set up appropriate levels.
So there are two functions where the physical tests are being placed in the stables.
So we have a map.
So we just used to map the physical presence into virtual addresses, so virtual address corresponding
to the start of the requested physical address, whatever size you have given you to convert them.
And it will give you a way to think of the appropriate page will give you the kernel, what you notice
then you have in your exit function you will be and mapping this.
So, again, the whatever the return address of I remember it is not the normal today reference.
So you should note that at least the reference I remember.
Their functions to access the.
Memory map by Iot maps, so you have different functions to access like NBN would be, you have.
Are you really eight, 16, 32 for reading and for writing?
You have your idea, you 16.
So why do you think we should not directly reference the memory like that if you reference memory?
So we now already have what will address that can't be radically different.
This what.
Your letters.
Why do you think we need functions like this?
