Which LinuxCNC works with hal paraport

hello,

What Linuxcnc rt-preemt is compatible with hal_parport ?

Tanks

Any Preempt-RT version should work with hal_parport, but you must use the "uspace" version of LinuxCNC.

Note that Preempt-RT often has worse latency than RTAI so may not be the best choice for
parallel port LinuxCNC configurations, though there is some hardware that has excellent latency running Preempt-RT

PCW thanks for your answer.

i have install linuxcnc-uspace on debian 9 with Preempt-RT linux kernel. I have plug a PCI board "syba SD-PEX10005" with MCS9900 Chipset.

I solve my problem to reload parport-pc module.
On my PC, latency test time is equivalent between rapi patch and linux kernel with Preempt-RT.
