From a news-item at VGR.com it appears that the current Articia-northbridges might still have DMA-related problems:
"Mr. S.W. who sends over screen shots of newer AmigaOne 800mhz G4 hardware, has sent over 2 screen shots of the new A1 with G4 running 'amigaone xe/g4 7451 800mhz, excalibur radeon 9000 pro 64mb ddr ram, valueram kvr133x72rc3/256 kingston'. He wants to know '.. if other aone users have that problem as well..', 'it never outputs the same checksum with dma enabled when testing an iso file which is larger than the swap space used'
You can see the Radeon 9000 Pro screen shots here: DMA On & DMA Off."

Articia: Still DMA-problems? : Comment 56 of 122 | ANN.lu |
Posted by Olegil on 21-May-2003 06:01 GMT | Ok, to get back On Topic, as it were...
The only way to get my AmigaOne to introduce bit errors is to run the VIA chip in DMA mode. I did a somewhat large file transfer (704MB) with a set of rather odd commands yesterday (10 points to him who has done something like this before):
I ran this on the AmigaOne:
olegil@naru narusegawa:~$ ssh olegil 'cat file1' | ssh olegil 'cat >file2'
Where 'olegil' is the office P4
Then I ran this:
olegil@olegil:$ md5sum file1 file2
d15c78c804f560a7b792d9aaefc58670 file1
d15c78c804f560a7b792d9aaefc58670 file2
Now I'm downloading the new kernel from cvs, and then I'll be working. After that it's SCSI + GigE time for my AmigaOne :-)
So, does anyone want to comment on the findings? Obviously the Articia must be causing the transfer from ethernet to memory to ethernet to be error-free, no? ;-) |
