kernel build

Hi. I made a custom kernel by copying GENERIC to a new file called MYKERNEL and I built kernel with KERNCONF=MYKERNEL. My problem is when i commented out those two lines below, make buildkernel command fails with errors. If I don't comment out these lines, make doesn't fail. I would want to know...

If you want to build a custom kernel to be used with an SD card image of FreeBSD, you have to pick a kernel source git version which works with that image. If you pick a wrong version you end up with something like "module 'kernel' exists but with wrong version" message and booting stops right...

Hi, I have installed FreeBSD on an amd64 laptop, and the only issue with it is an apparently long-standing bug in support for eMMC storage (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211705#c3), which I would like to investigate. But I'm stuck even getting an unmodified but locally...

Hi, I am new to buildroot and embedded linux, I have once build the root on my laptop using the buildroot and it took like 20 to 30 minutes, I want to know what kernel is used in the buildroot and how can I change it e.g. if I want to use the kernel of the freebsd in buildroot, would that be...

Hello all, it's 4 days since I trying to make custom kernel and fail with stuck in 'loading kernel modules' (no message just stuck in there). Because I'm curios why this happen, so I try to build another custom kernel without any modification at all, just copy paste the GENERIC as new file...

I have been compiling kernel but i am a little bit confused about how it chooses to include functionalities and drivers inside kernel or as external module. I have readed the handbook section and the "Absolute freebsd" compilation kernel book section, but i have some unresolved questions. From...

I have, for the past 3 days, been trying to get wireless access to my internet with FreeBSD. Yesterday, I got a dongle that IS supported by FreebSD via the rtwn drivers. Unfortunately for me, I need to access the drivers here, rtwn_usb. If you notice this has no option for boot time loading, and...

I am following the book "Absolute Freebsd" I suppose many of you will know it. I'm in the chapter that talks about the kernel, where you can remove drivers and options that you don't need. Well I have the following problem and I can not understand why, (I am a newbie) For example on my desktop...

Hello, I have just upgraded my system from 12.2-Release to 13.0-Release without any problems. I had a custom kernel set up before and wanted to compile one for the upgraded install too. Obtained relevant /usr/src from git with branch releng/13.0 and configured it using a copy of GENERIC. I then...

Whenever I try to compile my custom kernel (I have commented out some useless things from GENERIC) I get: ld: error: relocation R_X86_64_32S cannot be used against local symbol; recompile with -fPIC >>> defined in cam_iosched.o >>> referenced by cam_iosched.c:1171...

Hello, For the past 3 weeks I have been testing PF firewall and so far so good except for the rules not loading automatically on reboot. I load the rules using pfctl -F all -f /etc/pf.conf and all works great. I did change my default kernel to accomodate altq I actually had to redo the kernel...

I got the 12.1 source code from the base/releng directory of the SVN repository which would give me the latest 12.1-RELEASE kernel (p10). I used the GENERIC configuration to create the attached configuration file and then ran make -j4 buildkernel KERNCONF=SMALLER And the build goes well until...

Any help would be appreciated. Ive never seen this error and dont know what to do? MYKERNEL' ERROR: version of config(8) does not match kernel! config version = 600016, version required = 600018 Make sure that /usr/src/usr.sbin/config is in sync with your /usr/src/sys and install a new config...

Can I build a kernel and world in a poudriere jail? Is there a kernel and world port ? Or how to do ?

I'm just starting kernel development ( custom kernels, drivers, patching and etc... ) and i'd like to find a good tutorial of how to setup and environment for FreeBSD Kernel Development. For instance, executing custom code on a live kernel as well as debugging. Will I actually need two machines...

I have been using FreeBSD and tinkering with it for about 4 years now and I want to take on a bigger role in the community and really work on the FreeBSD operating system at a lower level in my free time to expand my skill sets. I know a little Assembly and am pretty versed in C. Any tips on...

Hello, Still learning the ins and outs of FreeBSD, so please keep that in mind. :-) I'm happy to read whatever manual that might help with this, but my searches have not turned up anything that is helpful. I have a server at home running FreeBSD 12.1-RELEASE-p3 GENERIC amd64. It is mainly just...

Hi, so I reinstalled FreeBSD a few days ago, and everything seemed to be working except for sound. I'm going through a slew of problems to configure it. My audio interface is a Focusrite Scarlett 18i8. When I first installed it, I got a desktop running with the dwm wm, Firefox, and the JACK...

Hello, I am looking for some feedback to improve my current setup/flow. What I have: * home server, with 12.1R with ZFS * a few jails that I manage with iocage (have a template that I clone to create new) * I build world and kernel from source from now and then, following handbook steps...
