Red Hat / Fedora :: How To Get Processor Type At Particular Root
Jun 16, 2010
How do I get arch/processor type at a particular root? On Solaris, I can get it by running
"pkgparam -R "$alt_root" SUNWcsu" (SUNWcsr)
Wonder if something similar for Linux exists? I know that 'uname -p' works for the current system, but I am looking to find arch for a system mounted at some root.
A processor is very important to me and I'm curious what processor to get for a new computer build. I will be using Ubuntu for most things except iTunes, HD movies, and a few low spec requiring games on Win 7. I am building it as right now I have a half year old netbook that can do most things just fails at game play and movies but it's alright. And I have a desktop with just Ubuntu that's about the same quality but 8 years old. I want to build a computer that will be very fast for the next 4 years enough to get me to college and buy a nice laptop. I am on a small budget of around 500- 750 dollars. I have most things picked out but processor has me stumped. To me processor is a bit tricky to replace and I'd rather get a higher-end one to start and stick with that than buy another CPU two years down the road.
I don't mind upgrading RAM, GPU, and or even the HDD at a later point but I want to get the CPU as close to perfect as possible. First I heard AMD processors tend to be a bit hot. I was wondering what cooler is $50 or less that does a great job at cooling a AMD AM3 socket CPU. I do plan to overclock a very small bit perhaps up to .3 GHz plus max. First I was thinking a nice core i5 at $200 and never really checked anything else. Then, I was thinking a hexa-core at 2.8 GHz I think but decided too much and didn't need six cores. The AMD socket type also supported USB 3.0 which I instantly fell in love with. Then I found a quad core Phenom II x4 black edition at 3.20 GHz for around $160.I liked the core unlocker and it looked incredible. Now I'm rethinking a bit again.
I found a dual-core that is same thing as the other AMD one above except well only two cores. I think that would do me fine I'd I'd save $60 by getting 2 less cores. With the things I use a computer for (Ubuntu, Win7, HD quality playback, minor gaming like Runescape, and small multitasking like openoffice a browser or two and perhaps some pictures, game or movie.) I also want to be able to do this quickly for the next 4 years without a hiccup or at least to a minimum if possible. I really don't want to upgrade CPU once I get that bad boy in there. I also want it ready for higher versions of Windows like Windows 8 is supposedly coming sometime in 2012 I've heard. I just want the best CPU to be fast and efficient, run cool, and work well for me for the next 4 years.
I have been looking at things with the uname command and was wondering if you can install a system with 64/32 bit when it was actually not the one you installed (e.g. you install a 64 bit OS on a 32 bit comp). I was basically wondering how to tell what type of hardware I actually have instead of what the Debian package installed. (In order to ensure that I am running the hardware the way it was designed.) At the moment, I am looking at my processor (uname -p returns "unknown") and the machine build (uname -m returns i686).
I am wondering, whether this is possible. Can I change processor architecture type in virtualization software for different virtual machines? Like I want to do some compilation on Intel itanium and I have physically intel xeon CPU.
i have installed ubuntu in my laptop.since i have AMD processor fedora doesnt support AMD processor..the recent version fedora 12 supprots AMD processor.i am doing my final project in ns2 hence it should support tht too!!! Which is the best choice to override ubuntu grub fedora 12 or redhat linux.
If I type "halt" from root terminal , the system tries to shut down , its closing all apps and services , unmounting disks , shutting down network etc, but finally I can see a message "System Halted"...But it doesnt turn off the monitor though..is this a bug? I have tried many times , however "poweroff" works properly..I was thinking since these are similar commands , bith should give the same result ...I usually use "halt" as it has fewer char to type!
My system software is installed on an encrypted LVM on hda1 and hda2. My home directory takes up the whole of hdb1 which is also encrypted. I can boot up into the kde desktop okay, but when I open up konsole and type 'su' and my root password I get the message "su: Authentication failure". I am absolutely certain that I am using the right password.
Even more strangely, if I fire up synaptic and give it that same password I am able to install software. Does anyone have any suggestions as to what's gone wrong and how I can fix it?
I can also type Ctrl-Alt-F2 and log in as root to do administrative tasks without any problems so I cannot understand why konsole has locked me out.
Ever since I turned on my notebook yesterday (Compaq Evo N610c) my processor has been working 100% all the time. I checked processes via System Monitor, and no process is doing such thing.
What can I Do?
Here's a copy/paste from top command
Code: [juan@x22 ~]$ top top - 11:02:39 up 37 min, 2 users, load average: 2.77, 2.21, 1.48 Tasks: 142 total, 3 running, 139 sleeping, 0 stopped, 0 zombie
Does anyone know if there is a way to "unset" processor affinity? So if you bind a process to just one proc, but then want to tell the OS to revert to normal behavior? Also, when you bind a process to a processor, can other processes use that process or does it have exclusive usage of that proc?
My configuration is as Follows: Intel Pentium Dual core 2.6 Ghz 4 GB DDR2 Apacar 800 Mhz RAM Gigabyte ATI Radeon 5450 HD GPU
I'm using Fedora 14 KDE but on startup it uses 40% of my processor. I'm using the proprietary 10.12 AMD ATI Linux Driver. I'm only using blur and woobly windows effect and I'm using OpenGL. Kubuntu/Suse never gave me this trouble. Even GNOME doesn't only KDE and fedora 14 is troubling me.
When i type the df command i see that /dev/hda1 as a filesytem that is mounted at '/'(root). Is /dev/hda1 a filesystem. I thought that it is a partition on my hard disk that contains the root file system.
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
I installed Fedora 12 at school on my external hard drive, using Windows Virtual PC 2007 to run Fedora at school on a dell PC with XP 2000, which works at school!However at home, i am using Windows 2007 os, I install Windows Virtual PC 2007, wasn't successful in running Fedora 12.As soon as Fedora begin to boot, an error message appeared which said,"An unrecoverable processor error has been encountered.The virtual machine will reset now".below the message it gives you only option to reset the virtual machine, however this is a vicious cycle
I am running Ferdora 12 (constantine) 64 with Intel Xeon 3.2GHz processor + 12GB Ram. I am running this machine specifically for number chunching applications but it isnt running as fast as i thought it would! Are there any tips to optimizing the speed of processors in fedora?
I wanted to try Fedora 12 Live/KDE on a newly-bought Fujitsu Esprimo P1500. Booting with no kernel options would just freeze the machine. After some random experimentation, I added the option "nolapic" and got a seemingly working machine. However, only seemingly, as it turned out that only one of the processor cores was working (the processor is a "Pentium(R) Dual-Core CPU E5300").
I am attempting to install a custom fedora build but it crashed, I then attempted the standard fedora build (.iso) burned on a CD and I got to the boot window but at some point following the colored lines going across the bottom of the screen it froze. symptom - monitor still on not hibernating, num key works caps lock doesn't , hard drive is spinning and so is CD drive. Has anyone had issue loading this build onto similar hardware?
My older motherboard is a MSI K7D Master which had two AMD Athlon 1800 MP's installed. My new motherboard is a HDAMA Rev G which has two AMD Opteron Socket 940 CPUs 2.4Ghz installed. When both chips are installed, Fedora will freeze when putting the system under load (i.e when transferring data). This has now happened to both the motherboards, once I remove the second CPU the system will run perfectly.
I think it may be a kernal problem as this also happens on other linux distributions. I have posted here for several reasons, a) to allow any other person searching for a fix a solution (all be it not a good solution), b) to request help on fixing this issue or request to who and where I should report this bug, c) to see if any other users are having the same issues. I should add that I once had the MSI mobo used in conjuntion with Windows Home Server which never had a problem when both chips were installed.
In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.
octave:2> test1.m error: can't perform indexing operations for <unknown type> type sh: gnuplot: not found Just to double check my work, I ran the following code: y=[1 2 3]; plot(y);
I edited the passwd file to modify the default shell for root from bash to tcshnow when I try to login to root it gives me the following error:"su: /bin/tcsh : No such file or directory"
the terminal and logged in as root i was changing file permissions and happened to change the root folder to 700. Now my icons have gone and i can't even access the terminal.
I was just wondering if it is possible to go to rescue mode using the cd and restore all the appropriate file permissions to root/ users if possible
I've started to get emails that would typically come from [URL] as [URL]. These emails come from services that send out emails (backup programs) directly, or from cronjobs. I've logged in as the non-root account and either sudo su - or su - to root and the restart the service at one point or another. If I login directly as root and bounce the service or cron the emails come across as from root. I don't see anything in my environment variables after I su to indicate what would cause this. I'm not sure where else to look? A pam setting? This seems to have happened between Fedora 10 and 14 (did a bunch of overdue upgrades recently) I've only got Fedora so I don't have anything to compare to. In Fedora 10 I did not have this problem.
