Some questions about building custom kernel

[hruodr]

Dear Sirs!

kldstat tells me that ums.ko was loaded, but this is not mentioned in loader.conf. I suppose some daemon loaded it. Is there a problem compiling the kernel with it?

In ums(5) I read:

device ums
device uhci
device ohci
device usb

In dmesg does not appear uhci. May I omit device uhci in the configuration file?

dmesg mentions the HD as ada0. In ada(4) I read:

device ada

But there is no such module loaded. Why? Should I include
"device ada" in the configuration file?

Thanks
Rodrigo

Module may be either loaded as dependency or built in statically to the kernel. You can list both loaded and built-in modules by the kldstat -v command.

Well, my posting supposed what you say, then I can suppose, that I did not express myself well.

I did not find " device ada" in /usr/src/sys/i386/conf/GENERIC, and kldstat do not mention the loading of such a module. That is why I asked.

I will compile the kernel with " device ums" and without device uhci, althoug ums(4) tells it is necessary.

It's created by ata(4).

Thanks, SirDice!

Could I then substitute " device ata" with " device ada"? §e

I compiled " device ums", without " device uhci" and it works.

Well, building the kernel does not take so much time as building world and compiling ports.

Yesterday took the compiling of X again hours. I compiled xorg-minimal, it took everything as dependencies, inluding perl, two versions of python, m4, bash and llvm (that alone talkes a lot of time). And at the end, xterm was not there, so that I decided to compile xorg port.

This fat X is not what I expected. The X server should run on small X-terminals. Today, I think, one calls such meager programs "embeded systems".

Making install of opera port was again a boaring opera.

Repeating this process for following stable would be a big distraction from my work.

No, I don't think that will work.

You don't need uhci(4) if your machine doesn't have the hardware. It's just a different type of USB controller.

It's orders of magnitude smaller, so that's not surprising

You could simply install x11/xterm. It doesn't need to be part of x11/xorg-minimal. I never install xterm because it's always out of date. I'm happy with x11/rxvt-unicode.

This fat X is not what I expected. The X server should run on small X-terminals. Today, I think, one calls such meager programs "embeded systems".

That's why x11/xorg-minimal exists. And strictly speaking you don't need everything from that either. You don't have to use the "meta-ports" they just make life a little easier.

Making install of opera port was again a boaring opera.

Yes, why would you expect it to be different?
