ab1a306d86 Works really nice now. 20 usecs base period => 50 kHz, 25 kHz pulse freq. 2024-04-07 21:45:53 +02:00

544dd5ed85 I works. 
Use 4.19-rt kernel
Ethernet Intel I210 controller
ethtool -C enp1s0 rx-usecs 0 tx-usecs 0
2 ms loop time in linuxcnc .ini and .xml and code
baseTimer period can be adjusted
startTime for baseTimer can also be adjusted.

dccbd97a04 Tried to optimize BASE_PERIOD but 12000 ns (83 kHz) is the best it can do right now 2024-03-23 20:27:32 +01:00

30a9f10c7b Well it works, network-wise. But there are those extra peaks that have been since the start. Let's see if I can remove them. Welcome StepGen3 2024-03-21 16:28:55 +01:00

8f26a10224 It works. I hate RealTek. Even with the r8618_dkms driver it doesn't work. I bought a Intel network card, set irq coalesce rx-usecs and tx-usecs to 0. Now it works works WORKS. No lost packages, no delayed packages. I hate RealTek 2024-03-20 17:06:24 +01:00

d4fed6cfe8 Yes it works now. Made another implementation of the pulse IRQ and all that. We'll see if I keep this or go back to the older. It is IMPORTANT, REQUIRED to use a 4.9 linux kernel for it to work. There are obviously bugs in the RealTek network drivers R8168/R8169 in 5+ kernels. All this work could have been avoided with a 4.9 kernel. 2024-03-17 22:04:52 +01:00
