Starting DMA issue

hey guys

so i started emerging kde-meta over night only to wake up and find it on 32/272...

called a friend and asked him to compile the last three files that my machine just emerged, took him 5 minutes tops.

im running gentoo on a turion 64 Compaq nx6125 laptop. I ran 'top' and nothings consuming large amound of my 2ghz processer... the biggest process was kacpid with 13% on and off. My processer is properly clocked at 2ghz as told by 'cat /proc/cpuinfo'.

Does anyone have a clue as to why Kde is emerging THIS slow.......................................................

1gig ram (128 shared for video) and a 2ghz 64 bit proc shouldn't be this slow for emerging kde-meta. Anyone have an idea as to why it would take so long?

*downloaded all files in advanced with fetch

if this is the wrong section i apologize

thanks

it definitely should compile faster...
maybe your cpu is overheating and it downclocks itself to cool down..?

i was reading about that in a sticky if i remember correctly, if its actualy doing so, how can i check if 'cat proc/cpuinfo' reports it at the correct speed?

after going deeper into some threads i was thinking maybe its a chipset driver issue as brought up here:

https://forums.gentoo.org/viewtopic-t-424455-highlight-emerge+slow.html

how do i check my chipset and if they're arnt drivers in the kernel what can i do?

1. i don't think cpuinfo is refreshing itself during runtime ( afaik only during boot ) - but i might be wrong...
2. it can be a hdd issue ( for example DMA not enabled ), hava a look at https://forums.gentoo.org/viewtopic-t-409484-highlight-.html

EDIT: also run

seems like DMA would be the issue based on these other threads

apparently i do NOT have the right chipset drivers and i dont see mine being supported: Radeon® Xpress 200M

im in my kernel config now and i have

running

removed generic/default IDE chipset support and added ATI IXP (i found out i use this after finding/using lspci)

still doesn't know what my PCI bridge is....arg

PCI is a standard so only one driver is needed: the PCI driver.

just because lspci says "Unknown device" doesn't mean no driver is loaded, it just means it doesnt have a name for that device.
lspci will list (and attempt to name) every PCI device in the system, regardless of whether drivers for those devices are loaded or not. it also doesn't have a name for everything

your slowdown issue is for another reason

alright thanks, didn't know that. Can you please give some insight in solving this issue then?

dsd · Posted: Sun Jan 22, 2006 7:18 pm Post subject:

if DMA still isn't on then that is almost certainly the cause of your slowness

please post the output of:

lspci
lspci -n
uname -v
ls -l /usr/src/linux/arch/i386/boot/bzImage

hdparm has diagnosed the problem - you have no dma support. hdparm cannot fix this problem though. You need to find the correct chipset driver for your IDE. try googling

chickenselects · n00b Joined: 10 Dec 2005 Posts: 33

so i figured. Well now for the noob question. What should i even google for... and what do i do with the driver once i find it?

Still new to linux and i really dont know which direction to go in to find these drivers

-thanks....

sorry, forgot you were running 64 bit, i meant "ls -l /usr/src/linux/arch/x86_64/boot/bzImage"

however i think i have enough info to say that you have made a mistake when changing your kernel config. your "uname -v" output says that your currently running kernel was compiled on jan 18th, yet this forum post seems to suggest that you added ATI IXP PCI IDE support on the 21st.

use this doc as a reminder of the process of installing a new kernel image:

it seems no matter how many times i recompile the kernel and follow the steps in the handbook it always says the 18th?

i dont see any changes as of those steps

Just an idea: Could it be you forgot to mount /boot before installing the new kernel?

chickenselects · n00b Joined: 10 Dec 2005 Posts: 33

did it in the order the handbook said, thanks for trying though

bollucks is right... so, could you post your grub.conf? - maybe there's the probelm...

yep, as well as that, detail the *exact* procedure you are using to add an option to your kernel (all the way through to rebooting the system)

Aye... following *only* the steps in chapter 7 of the book will get you nowhere bcs. /boot was mounted in chapter 4 already... just a gess...
