Hi,
is there any way to control the ILFB / DLFB?
Can I clear them somehow?
How can I make sure a certain entry there gets overwritten?
(I'm using a P4080 with e500mc.)
What is their replacement policy?
Thanks in advance.
Hello Clemens Reibetanz,
I am not aware of a way to clear line fill buffers. But you could use cache management instructions, such as dcbf and icbi to flush data out.
The DLFB/ILFB are located in LSU, why do you need to control or know the status of them?
The replacement policy of the line fill buffer is not documented.
Have a great day,
Lunmin
