| 10:59.59 | mne | Hi. On AT91SAM9260 there seems to be a problem with the ethernet buffer being too small to get data out of SDRAM fast enough. You might know this from the "eth0: TX underrun, resetting buffers" kernel messages. On at91.com I found patches for the macb driver so that the internal 4K SRAM is used as TX buffer which does not solve the problem (4K is still way to small). However, it seems to help help a bit since the TX underrun errors seem to get less frequent and |

| 13:58.55 | MonMotha | mne: If the existing performance is sufficient for you, I'd just patch out the printk for the message if you want to make it be quiet |
| 13:59.22 | MonMotha | I seem to recall that there is a hardware errata that may be related to this, as well, so check to see if that may impact you |
| 14:00.56 | mne | yes. I found it in the datasheet and the suggested solution is to use SRAM as tx buffer. I created a patch out of the experimental at91 patchset available at linux4sam. The patch adds SRAM TX buffer support for macb. With the patch applied, the ethernet performance is pretty much the same, but I get far less TX underrun errors |
| 14:02.17 | mne | I read that changing the bus matrix priorities can lead to lower EMAC memory access times. You don't know the linux kernel location where I can specify priorities for the different slaves, do you ? |
| 14:02.49 | MonMotha | I do not |
| 14:03.04 | MonMotha | it's also possible that you're already hitting some other wall |
| 14:03.22 | MonMotha | It's only a 200MHz ARM9, after all |
| 14:04.18 | T0mW | only, heh |
| 14:04.25 | MonMotha | T0mW: indeed :) |
| 14:04.28 | T0mW | recalls 8051 |
| 14:05.24 | MonMotha | But we're talking about 100Mbps ethernet. That's a lot of data to throw around. If it's doing a lot of other stuff, it may just not have the memory bandwidth or CPU time to handle the header info |
| 14:05.28 | T0mW | I'll be replacing a 15 year old design of mine which is 80188 with an S3C2440 soon. SPEED! |
| 14:05.54 | T0mW | yeah, people think they can get desktop performance from embedded stuff |
| 14:06.13 | T0mW | Although |
| 14:07.12 | T0mW | that IOP348 (?) board I played with did a credible job of an 8 drive raid-5 array + gigabit ethernet. It was no performance slouch |
| 14:07.18 | MonMotha | my 300MHz PII could barely keep up with 100Mbps ethernet, IIRC |

| 14:07.35 | MonMotha | when I put a decent card in it, it managed |
| 14:07.47 | MonMotha | but with a crummy linksys, it had trouble |
