MIPS kernel snapshot testing
Hi,
I just successfully booted:
http://people.debian.org/~tbm/mips/kernel/r11922/linux-image-2.6.26-1-r5k-ip32_2.6.26-1~experimental.1_mips.deb
and have made some observations.
First and foremost, the IP32 kernel appears to have performance issues.
As the only other OS I've managed to boot on this O2 is the ancient
Gentoo Live CD, I've used it as a measure of comparison and am
attaching below some readouts from both OSs on this machine.
Running hdparm -Tt /dev/sda we can see that it appears the Debian
kernel has about only a third (!) of the memory throughput of the
Gentoo kernel (results attached).
Also, while the dmesg for Gentoo doesn't show anything worrying in the
SCSI subsystem, our dmesg shows:
[17179602.240000] sd 0:0:1:0: [sda] 4197405 512-byte hardware sectors
(2149 MB)
[17179602.280000] sd 0:0:1:0: [sda] Write Protect is off
[17179602.300000] sd 0:0:1:0: [sda] Mode Sense: b3 00 00 08
[17179602.320000] sd 0:0:1:0: [sda] Write cache: disabled, read cache:
enabled, doesn't support DPO or FUA
That is, it disables the HDD write cache for no apparent reason.
What I also find worrying is the usage of 4KB kernel page size on the
r5k kernel, surely r5k should support 16KB and wouldn't that enhance
performance a bit?
Both distros see the USB adapter and in Debian (which we care about) it
works perfectly, udev/HAL handles USB storage devices very well.
Moving on to the sound, the PROM tells us we have Audio : A3 version 1.
When I took it out and had a look at it, it says it's a (fairly
standard I assume) Moosehead AV board and the chip on it is an AD1843.
During bootup, however, the module doesn't get loaded.
A modprobe snd-sgi-o2 yields:
[17179964.716000] ad1843: AD1843 won't initialize
[17179964.716000] sgio2audio: probe of sgio2audio failed with error -5
Please find attached below my test results.
Thank you for your time,
Jimmy
