[Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

For a few days, I've been working on a new implementation of rtapi called "uspace". If you read the -commit message or lurk on the -devel IRC channel, you have seen some talk about this already. "Uspace" uses POSIX threads, rather than the old libpth implementation. If the rtapi_app executable is

Hi Jeff, I have been following your thread with great interest. I am not to clued up with the different flavours of kernels and RTAI interfaces though. Would it be possible to give us laymen a simple description of what your work means to us, what it intends to achieve and what we have to look

Re: [Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

Thanks a lot Jeff. I also have a better picture of the kernel issues and requirements. Would it be correct to say that the future of motion control would be hardware step generation rather than the software step generation? It would seem that the world of parports and software step generation is

Re: [Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

I am surprised how long the LPT port has lasted. Many of the new Intel Bay Trail boards either have LPT ports or a header on the motherboard. Apparently the LPT port must be used by a lot of embedded systems. Otherwise why would they continue to include that? It seems like the PCI slot is

Since it's been about a week, here are some incremental updates about "uspace": There's now a wiki page, which covers how to obtain and build the branch: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Uspace The branch has been rebased several more times, squashing out bugs and adding a few new featur

What is cool is I found the rt-preempt kernel from the synaptic package manager - installed it - built linuxcnc to use it. it just worked. (this was on wheezy) (I was testing the 7i80 ethernet device) http://electronicsam.com/images/KandT/testing/ethlatestbuild.png sam On 07/06/2014 08:58 A

Re: [Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

Not a lot has changed since my last report. the rtos-uspace branch has been rebased a few additional times. In the absence of any concerns raised about this branch before July 20 (Sunday), I plan to merge my work to the linuxcnc master branch. So if you want to raise any issues or just offer rev

Re: [Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

I have been testing the Ethernet branch. (mesa 7i80) no issues what so ever. Some of the hardware I have been testing is the GIGABYTE GA-J1800N-D2H rt-preempt latency 36us http://electronicsam.com/images/KandT/testing/j1800.png GIGABYTE GA-J1900N-D3V rt-preempt latency 66us http://electroni

Re: [Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

Positive feedback is always welcome. Has anyone tried the branch on an rtai kernel? The chance of trouble is relatively low, but doing something with it beyond running the testsuite would be great reassurance. Jeff -- W

Thanks to everyone who tested and provided feedback on this project. It has now been merged to the master branch of git.linuxcnc.org. The total scope of the project was 116 files changed, 4026 insertions(+), 4452 deletions(-) in 43 commits which is a slight increase from the first time I reported

Re: [Emc-developers] "jepler/rtos-uspace": a new POSIX realtime branch

Hi Jeff, I have been trying to modify our pci driver to run on userspace too. I prefixed the necessary pci functions with "rtapi_" as you suggested in a previous email e.g. rtapi_pci_get_device. However, these functions are undeclared in the rtapi header files in the 2.7 branch. I only found them

Dear Sebastian, Much later than expected, but we could finaly finish gm6-PCI driver USPACE support, tests, and we made also some fixes (all togeather 3 commits): https://github.com/geris2/linuxcnc-mirror/tree/gm-fix Could you check in to git? Thank you for your support, Bence Gergő 2015-01-27 1
