Hello Jerome,
I started to looking at the mm/hmm code and having a question at the
devm_request_mem_region() call in the hmm_devmem_add() implementation:

The main question is here as I am a b
Thank you! I still have a long way to go in kernel.

[see other replies]
Look into terminus technicus "scaling math" as a replacement technique
(in-kernel this is being used e.g. by clocksources/clockevents).

Don't do it. :)
In kernel land we don't wan
May I can use the ''double" as a basic variables?
When I define the "double" as a function return type in linux kernel,the error
is "error: SSE register return with SSE disabled".
How to fix it??

If you do a make install, it will be copied to /boot directory
automatically;-)

yes, you do. but System.map is only needed to do symbol lookups, for
times like debugging.

Dear all,
After I compile and upgrade to a newer Kernel, do I need to copy the
System.map from /usr/src/linux/ to /boot/System- and link it to
System.map?
Thanks in advance

Hi,
Just wonder what exactly the difference between buffer and cache in linux
memory management is.
Cache is used for filesystems, so that files read from a fs are kept in
memory in order to provide faster access next time.
Then what is buffer used for?
As executables are also kept in memory, ar

No way. Formally it is IP_RECVTOS, followed by IP_PKTOPTIONS.
But getting TOS via IP_PKTOPTIONS is no

Doesn't work. Returns the TOS of outgoing packets, which defaults to 0 even if
there is a TOS set on incoming traffic... that was what I tried in my first
test program.

I've scrolled through various code in net/ipv4, and I can't see how to query
the TOS of an incoming TCP stream (or at the least, the TOS of the SYN which
initiated the connection).
Someone has sent in a feature request for squid which would require this,
presumably so they can set the TOS in t
