Turbonet Driver Update

[old7]

If you are doing large transfers on a local network and are seeing the transfer pause for a second or so every now and again then updating the driver will correct this problem and speed up transfers.

Has anyone done the upgrade on v3.1.0 from bash? I tried it and got "can't find a valid install".

Here is Nick's instructions:You can update the driver on a live tivo...

1) make the root partition writable:
- ftp upload nic_config_tivo from the driver-only .zip to /tmp on the tivo.
- chmod +x /tmp/nic_config_tivo
- run /tmp/nic_config_tivo
- leave sitting in the menu - this will leave the drive mounted as writable.

2) ftp the new drivers (ax88796.o and ax88796_debug.o) to /lib/modules

3) return the root parition to read-only
- if using nic_config_tivo choose 0 to exit.

4) type 'reboot' to reboot the tivo.

Note - if nic_config_tivo complains that it can't find a valid install then you will need to pull the drive or do everything manually.

Also, if the old ax88796.o is not in /lib/modules then you should use nic_install.

AlphaWolf found the problem with installing on v3.1.0:

Don't use Nick's instructions.

1. Replace the ax88796.o file in /lib/modules
2. Edit /etc/rc.d/rc.arch and change line 37:
if /sbin/insmod /lib/modules/ax88796.o macaddr=$SerialNumber ; then
to
if /sbin/insmod -f /lib/modules/ax88796.o macaddr=$SerialNumber ; then
3. Reboot

for v2.5/v2.5.2 with KRavEN upgrade or the v252 xupgrade you can omit step 2.

I'm not doubting the intentions of the update, but has anyone performed any quantitative analysis of transfer rates between the two module versions?

In the post they say to check your big downloads, so if you only transfer small files you don't see the problem.

I just saw that they say if you see your download stop for a second then you are looking at the bug, that's whay I see, so I'll upgrade and let you know how much better is for me.

All I've seen is that it is ~50k/sec faster.

Hi,

The problem may or may not show depending on the round-trip timing of the TCP communication. It depends on the delay through your network (hub vs switch, how many etc) and the time it takes your PC to generate a response.

For one setup you may not ever see the problem and the new driver will not make it faster. My origional development system does not show this problem, for example.

In an extream case it could be possible that you could see small bursts of traffic and going idle for a second at a time (caused by tcp waiting for a timeout after loosing two ACKs in a row). In this case the new driver will dramatically improve the performance up to that of someone who is not seeing the problem.

With my current setup I see the problem every now and again and the bug only slows things down a little.
