DSP Registers are not saved in Context Switch

[Daimonion1980]

Hey

As the dsPIC33 has the same Architecture except the additional dsp register and as you wrote your kernel is useable for dspic devices why are you not saving the dsp Registers during a context switch?

It should be inserted in File tneo/src/arch/pic24_dspic/tn_arch_pic24.S and during stack initialisation.

So that an working dsp operation with Registers ACCA*/ACCB*/DO is context save.

Hi, thanks, that's a good point; I recall that I planned to make sure the code is correct for dsPICs, but apparently I did not get around to implement that properly.

At the moment I don't have any dsPIC device around though, so would it be possible for you to craft a PR? I'd be happy to accept it.

I do not implement the whole kernel. At the moment i just use the context switch code from your dspic arch file to solve a special problem of my actual project.

But when i'm ready, the code is tested and microchip had a look through it i will provide you a PR.

Just give me some days....
