recognisiing new cpu [SOLVED]

[schorsch_76]

[mikefot]

Dear Tony,

I ran genkernel with one cpu only as you suggested and the kernel compiled successfully.

You were right.

My casecom 350W power supply is too puny for the box here.

The idle power draw of an FX 8350 is 91W from the wall.

The average power draw for it in use is 182W in the tests done here:

http://www.tomshardware.com/reviews/fx-8350-vishera-review,3328-16.html

Peak power draw is measured as 196W in this review:

http://techreport.com/review/23750/amd-fx-8350-processor-reviewed/4

and with what appears to be some overclocking as much as 350W here

http://www.corsair.com/en/blog/2014/november/fx-8350_power_to_performance

The engt 430 graphics card draws all its power from the motjherboard - a psu of 300W with 18 amps on 12V rail is recommended minimum by NVIDIA.

The power supply I am using is a CASECOM 350W device.

The power supply that needs to be fixed is a Zalman zm 1250 platinum.

According to this link http://forums.overclockers.co.uk/showthread.php?t=17897600 it might only be supplying 8A at 12v to the CPU. The Seasonic 380 supplies twice as much power. Your zalman gives 45A, enough to weld with!

Dear Tony,

Right enough it seems as though the casecom power supply is pretty puny.........


The zalman is reviewed here:

http://www.tweaktown.com/reviews/5144/zalman_zm1250_platinum_1250w_80_plus_platinum_power_supply_review/index.html

It has two 12V rails; one rated at 45A and the other at 65A.

That's enough for Victor Frankenstein......

I'll let you know once I have got it fixed.

Dear Tony,

I have installed gentoo on a kaveri box I have here while I get the zalman psu fixed for the piledriver box.

It went OK and genkernel seems to have worked.

I used debian annd gparted to make extra partitions on a disk that also had a number of Oses on it.

This worked.

I used the gentoo minimal disk a bit so I could use the mirrorselect package but I probably could have emerged it and carried on with debian.

I switched back to debian after I ran genkernel.

I finished off the install and successfully rebooted.

grub did not see the other OSes but I fixed that using the system boot repair disk I have.

I now want to go back into the gentoo install and try compiling and configuring the latest kernel and then have that kernel supersede the genkernel kernel.

Last time I tried to this in the old AMD 3400 install something went awry and the new kernel went missing in the wrong directory and I ended up being stuck with the genkernel kernel instead.......

This time I am hoping to improve on that.

I am going to read up on the kernel compilation and configuration and in particular on the target directory for the executable etc before attempting it.

Wish me luck,

Regards

Dear Tony,

The machine I have uses a Gigabyte F2A78M-HD2 motherboard.

It does not have as many usb ports and other bells and whistles as more upmarket boards.

In think the one you are interested in is probably superior to this one but it does work OK.

I have been using it for a year now.

The pc has a 500W psu in it.

There are a few motherboards that are similar in quality to the one you are interested in. I remembet MSI had a good one.

But I think it is a fair choice.

On with the zalman repair job.......

Now you know about it you won't want a lesser psu.

Dear Tony,

I have sent the big power supply unit for the FX8350 box away to get sorted.....

As soon as I get it back I will remove the small 350W casecom psu and install the big beast and have a go at the manual kernel configuration etc.

It does have PFC protection.

I might try getting a psu tester or cheap multimeter like device to check on it.

I now see that a good power supply really is important and computers use more power than you think........

I originally went for the big psu because I wanted to install a e.g. a GTX 970 graphics card in it at some point and I had read that if you used a big powerful psu which
would not be troubled by it then you would be protecting the motherboard and cpu etc since the electronic components would all run at the correct voltage etc 100%
of the time........

I now realise that peak power demand can be greater than I had envisaged.

Dear Tony,

Hello after a while.... The psu in the FX 8350 box has been replaced with an Antec 1300....

I am thinking to try upgrading from the genkernel kernel I have on the kaveri box to the latest kernel which I would compile and manually configure.

If I can make that work I will try the kernel compilation on the FX8350 box using all 8 cpus to check the psu is getting enough juice (should be now) and then do a manual kernel installation there aswell.

I hope you are OK.

Dear Folks,

I logged in to the gentoo install I have on an AMD Kaveri APU box I have and ran the emerge update deep @world commands etc to update the system which seemed to run well.

I ran emerge depclean a number of times and used the revdep-rebuild command which seemed to run OK as well.

I had originally used genkernel and now want to manually configure and compile the latest kernel from source.

The kernel I have is 4.1.15.

I emerged the kernel source package - it said the kernel I already had was the newest one. Running eselect kernel list showed this one kernel.

I then googled around for some hints on the correct configuration of the kernel in a kaveri box - in particular the radeon graphics card.

Using the menuconfig tool I set the graphics driver to build the radeon card files into the kernel (I emerged the radeon ucode package).

I did not install the firmware package and/or choose the external firmware option in the compilation.

I checked a number of other kernel settings based on recommendations in the gentoo documentation which seemed to be OK.

It seemed as if the layout of kernel options had changed a lot in version 4 relative to 3 so I couldn't always find certain options to check they were correct.

I did make -j9

then

make install_modules

and then

make install

I should have done make -j5 because the kaveri has 4 cpus not 8.


I am not sure if the compilations were successful.

I can post log files e.g. from/var/log etc using pastebin if anyone would be kind enough to take a look at them and I can rerun the compilation again as necessary.

If I can successfully configure the graphics card in the kernel compilation I would then be looking to install the xserver packages and then e.g. KDE etc.

Suggestions appreciated.

Regards

Mike, the Kaveri seems to do a lot better with the 4.7 and up kernels. I have an A8-7600 on a gigabyte GA-F2A88X-D3HP

Here is my 4.8.8 config http://pastebin.com/R1katxuC In make.conf I have set VIDEO_CARDS="amdgpu radeonsi radeon"
I don't know if this is ideal but it works. My buildscript:

Dear Tony

I realised that I might not have mounted the /boot partition when I set up the chroot into gentoo yesterday.

I did it and ran make install again in case it had not put the kernel into the /boot location.

I got this output – the same as when I did it yesterday:

[Tony0945]

emerge -av =sys-kernel/gentoo-sources-4.8.9 --autounmask-write

After it runs, you will have to run etc-update and do it again.

If you use your old config be sure to make oldconfig first. If you use mine, give the supplemental name "tony" or something so you can distinguish it from some other kernel.

I run grub legacy, so I'm not sure what all you have to do to update the menu. Updating the menu was confusing so I never went to grub2. Editting the menu in grub legacy is easy.

On the SSD, I plan to try refind which is supposed to find the kernels by itself from the name vmlinuz.

Building your kernel is one of the most important steps in Gentoo, so take it slow and make sure you understand each step.

Dear Tony,

Many thanks for your helpful suggestions.

I ran the command you gave me for the kernel source as you suggested:

[Tony0945]

You pretty much have to install X and see if it runs to troubleshoot it. There will be helpful logs in /var/log

[Tony0945]

If there are hardware problems, check the settings in the config file I sent. I think the boards are very close in built-in hardware. Remember r8168 vs r8169. I think r8169 only supports very old Realtek chips.

Dear Tony,

I installed Xorg and then booted up gentoo and ran startx.

It crashed grumblling that the kernel modesetting was not supported.

I began to wonder if I needed to reconfigure the kernel to turn on extra KMS related features etc that I might have missed etc and then recompile the kernel and try again etc.

But when I googled around I noticed that someone had the same error and fixed it by using a command called modprobe.

They used it to turn on a module that could set the KMS for the graphics card.

[Tony0945]

Yes! Post the results of your modprobe and the results of "grep -i RADEON /usr/src/linux/.config" or "zcat /proc/config.gz | grep -i RADEON" The latter is preferred because it directly examines the running kernel.

After runni ng startx you should have a file called /var/log/Xorg.0.log , please use wgetpaste on it and and post the URL. " wgetpaste /var/log/Xorg.0.log"
