Hi,

sorry, this is a bug introduced with the latest release while fixing an FP context corruption bug. I've fixed this now in SVN. So grab latest libogc from SVN, please.

No. Because both use the DSP to do the channel mixing.

Try calling ASND_End() after MP3Player_Stop(). This will shutdown the ASND lib and will stop the dsp task. Perhaps this helps.

Izhido: This is not going to work. Because we do lazy FP context switching, which is done thru the FP unavailable bit in the MSR, this would disable this path. Furthermore there won't be a FP context switch anymore then. The solution to your idea would be to do the FP context switch at every thread ...

A short note to the FP context switch: In case there was no thread context switch, ie same thread keeps running after exception, there won't be a FP context switch. In thread_dispatch_fp (lwp_threads.c) i check the executing context against the currently used FP context. And only if thread context ...

The point with disabling the FP bit in MSR in the irq_exception handler is that we want to achieve lazy FP context switching. Having this bit enabled in every thread context would mean to do FP context switching on every thread context switch. Which in turn is a very expensive task then. Remember we ...

Well, tbh, it should somehow destroy the FP registers if you disable the interrupts. There's an issue, marcan figured, when you have 2 threads for example. And both do FP calculations and in both threads you disable the interrupts before the calculation and enable it after the calculation. This test ...

Hi,

Do you disable interrupts somewhere around the initialization of this table ? I remember having some issues with that in conjunction with another thread doing some FP calculations.

Hi,

that's great news! Nice to hear you got it working!

Well, in my setup GX_DF_CLAMP is still used even though i've GX_AF_SPOT turned on too. So for my understanding in this setup the vertex normals are used aswell in the lighting calculation. As a little sidenote: I didn't renormalize the normals in the RMS mesh loader when i ported it over to ...
