kernel-3.10.0-693.2.2.el7.x86_64 update centos 7.4

 

Hello guys.

 

 

I'm update my Centos 7.3 to ---->> CentOS 7.4 and new kernel 3.10.

Re: kernel-3.10.0-693.2.2.el7.x86_64 update centos 7.4

you need to call updateNIdrivers, but nikal.c needs a small patch (add NULL to the arguments list of do_munmap) in order to compile.

Re: kernel-3.10.0-693.2.2.el7.x86_64 update centos 7.4

New Kernel kernel version 3.10.0-862.2.3.el7.x86_64.

3.10 is really ancient and unsupportedDo not use in production anymore.

Current stable is 4.16.8, LTS is 4.14.* (3.10 never was LTS)

  

fail updateNIDrivers.

nikal:     .id = GENL_ID_GENERATE,

It is (actually was - long ago) in uapi/linux/genetlink.h. But it was never intended for general use, just a workaround for some special drivers, and looooong obsolete. Should have never been in uapi in the first place.

genl_register_family_with_ops() was dropped long ago. Drivers are supposed to statically initialize the struct.

 

Oh, BTW, using those inline functions makes the driver a derivative work, so GPL applies.

@okay, @NI: can we have the full source code now or shall we file criminal charges ?

 

Few weeks ago I made another contact attempt to resolve this ancient problem.

No answer. NI doesn't wanna talk to me. Obviously they're absolutely NOT interested in any solution.

Ergo: no Linux support whatsoever.

 

EDIT: I really wonder what they're doing w/ netlink in the first place.

It's NOT supposed for daq devices at all - we have IIO for that. It really seems they have no idea whatsoever how the Linux kernel works.

Re: kernel-3.10.0-693.2.2.el7.x86_64 update centos 7.4

centos 7.4 supported by National, I'm sure about that.

Re: kernel-3.10.0-693.2.2.el7.x86_64 update centos 7.4

One specific distro in one specific version, with one specific kernel version (or very small version range) in one specific configuration is far from being "linux support". (it'd somewhat about 1 permill of that).

 

When it comes to kernel drivers, supporting binary-only drivers is practically impossible.

Requires an extrem amount of work - magnitudes more than just rewriting everything from scratch and bringing it to mainline.

 

There're hundreds to thousands of factors that must match exactly in order to make a kernel module really fit to the rest of the kernel on binary level (the hard lifting is done by the compiler, lots of macros/inlines, ...). There is not, never has been any kind of binary compatibility between individual kernel versions and configurations. It's a monolithic kernel - "modules" here just means that some pieces of the code can be put into extra files that are loaded after bootup - they're not separate programs (like on other OS'es), not even libraries. This is a fundamental design decision which won't change in the forseeable future.

 

The proper solution is to just write IIO drivers. Here, the framework already does all the heaving lifting (buffer management, signalling, sample conversion, ...) in a generic way. We just need the little pieces that speak to the actual hardware. Usually few hundred LOC per model - with proper specs about 2..4 weeks of work. For the LV side, they could just add a generic driver that speaks to IIO into DAQmx, and then all IIO devices work w/ LV.

 

To put it into numbers: maybe 10k$ per model. Assuming they had 100 different models to support, we end up w/ 1Mio. Peanuts for a billion-dollar-company. 

 

The fact that they just don't invest these few bucks - over many years now - and instead burn resources with their kernel blob crap, clearly shows they don't have the slightest interest in any decent Linux support. They don't wanna have any market share in the Linux world - otherwise they already would have invested the few bucks, years ago.

Re: kernel-3.10.0-693.2.2.el7.x86_64 update centos 7.4

Addendum: just in case someone asks where I get these numbers from.

Well, I am one of those folks who regularily write kernel drivers.
