dmesg, logging and ATI driver

[djf_jeff]

Hi,

I have installed the lastest ATI driver and get something like :

[fglrx:firegl_alloc_bufs] *ERROR* Failed to create buffer queue (-12)

that fill up my syslog and dmesg. When I play at Unreal, I think this make the unresponsive (it log up to 10000 entry of them). I try to fix this issue but I found nothing on the net. So I have to "hack" this and make a quick fix.

What I do, is before I start the game, I run a small script that remove kernel logging from syslogd.

But, how can I remove the entry to show up in dmesg? I have read something about the "-n X" switch. How to set it back to normal behaviour after playing my game?

And what to do and klogd?


Thanks a lot in advance

Well, any logger just reads the output of various sources (/dev/log, /proc/kmsg...) and writes the output to files. You can usually apply filters to these when it comes to actually saving the logs. dmesg is a little different. It outputs the contents of the kernel ring buffer, you can't really change what's in the kernel ring buffer (besides clearing it with dmesg -c). Using the -n flag will only show messages with a certain log level. It doesn't however change the contents of the buffer, so you don't have to worry about losing any information.
