what is the difference between kernel-rt, kernel-trace and kernel-rt_trace?
i am using desktop kernel and what would it be if i use one of them in my desktop system?
could my wine games or opengl games run smoother with it?
which one has best performance on games?(including default and vanilla even xen kernel)
and last one
what is kernel-firmware?
You can easily google those.
The only kernel/s you need be interested in are
default
desktop
pae
desktop or default are most likely
The windows emulator ‘wine’ has nothing to do with the kernel.
Your graphics setup on the other hand, may be the issue, but you need to provide details of your system, and games etc…
I didnt ask pae kernel cuz i am using 64 bit 
I think everything has something to do with kernel
For example if you compile kernel wrong your computer would probably slower
I heard about realtime kernels may give performance boost on games.

Possible, I don’t know.
But I wouldn’t worry too much about it. Are you talking win games or Linux?
both :)…
This is one of my favourite topics
I want to learn is there any disadvantages of realtime linux kernel?
is it suitable for normal desktop use?
why it is not default in opensuse?
anybody to answer?
If I understand your question right, a real mode kernel does not use any of the advanced protected mode features available since 80386 came out. Linux uses protected mode always which is why it is so stable. Under protected mode, the processes are each granted a secure private space to work. If the process fails or misbehaves it does not bring down the whole system or interfere with other processes.
The kernel part of M$ windows dos, 3.xx, win95, win98 gradually moved away from real mode but could still run in real mode if they had to. By Windows XP real mode could in some cases be forced.
Is real mode Linux kernel advantageous … absolutely not in server or desktop (just too many processes that could bring down a system if they fail)
IMHO
Ah, I think this discussion about the kernel-rt package, which is a different thing altogether from realmode CPU operation. The only way Unix can run in realmode x86 is with segmentation because 640kB is so limiting. And some products did. But that’s all ancient history. Realmode in Linux is only used during boot, because that’s how the x86 and x86_64 CPUs start off, for legacy reasons, even if it’s the hottest CPU just out. So some people in the world, e.g. boot loader writers, still have to know 8086 ASM code.

A real MEMORY kernel is a lot different than a real-time kernel. The
latter is designed to provide a well-defined response to external events
with a maximum latency.
For normal desktop type actions, you might find that the response to key
or mouse events would be worse for a real-time than for a normal
interactive kernel for the main reason that the normal kernel can take
as much time as is needed to handle your stuff without worrying about
the latency for other events.
alright then
as tony asked
what is the difference between kernel-rt, kernel-trace and kernel-rt_trace?
nobody knows? 
I think caf42926 made it clear on this thread that this is something that you can google.
Why should someone spend extensive time typing up a detailed response (and possibly make a mistake in their understanding), when you can get this easily from google, with a higher probability of a correct answer?
The time wasted (wasted in typing up a response) is better spent helping people with real problems as opposed wasted on those who won’t use google.
Our forum is NOT in place for those who can not use google. It is in place for those with openSUSE problems, where we do try our best to help.
To further illustrate my point:

you can probably find your answers through online research…maybe
start here: http://en.wikipedia.org/wiki/RTLinu or here

if you dont know the answer it is ok, you cant know everything anyway
if you know the answer you should share
knowledge of people scale up with sharing
of course i have googled that and found nothing about differences between rt/trace
believe me this forum is the last place for ask something for me
cuz i always wait for hours just for an answer, forum members are so slow
and the answer is rude, not helpful, not informative and nothing and nothing
i see opensuse community is very helpful and kind and have so much intelligence to share
thanks you so much
hey people, this is the open source
if we dont share something, why open-source and free software stand for?
i can see why so much people gave up opensuse and moved ubuntu
i can see why opensuse didnt grew up in international area
congratulations people
i have been here just a few weeks and you made me angry many times
dont answer my question
i dont care it anymore, i will find it myself

At home, I use an RT kernel for everyday use (I need an RT kernel for music recording purposes). Of course, you have to compile your video and your wi-fi drivers for that kernel, but that’s no big deal.
Then you should advise of us what you know and what is confusing you instead of snarky comments saying “nobody knows”.
I for certain would not waste my time typing what I know about this given the amount of information that could be provided, and I am one of the more prolific posters on this forum. Imagine how everyone else feels when a user gives NO INDICATION that they have used google, when they IGNORE a suggestion to use google, and provide a post like you just did. >:(
In an advanced case / question like this, you need to show some effort to get any effort in return. Thats true not only true in a forum, but also outside a forum in life in general.

you might be able to solve the gamers questions: have you seen any
“performance” boost when gaming?

it is exactly ““nobody knows? :(””
a sad image. it means i am sad cuz i really need the answer
and there is a question mark in comment. it means it is a question, i didnt mean nobody actually knows, i mean is there anybody know??, it is forum language and i suggest you should learn it cuz you are a moderator, you are responsible of this forum. you should help people instead of rude, non-helping, non-informative, horrible messages.
dont forget it is an official forum of opensuse, you are not a random user, you should be fine and kind in any situations
it is not a snarky comment “nobody knows”
i didnt want to be snark and my other comments prove it
but you are rude, you didnt help, you just wrote unnecesseary messages
shame on you dear moderator
dont waste your time on me until you write helping messages as expected
Then you did not read the links I provided.
Then you did not read the posts of others.
There is good information there.
There is a saying, its possible to lead a horse to water, … but one can not force the horse to drink.
Show us you are making some effort, and you will get effort in return.
As a moderator all I see is a user who refuses to read the content of the links, and read posts that have been made with the information requested, and instead replys with a snarky “nobody knows”.
