DerekKozel[m]florent: Has there been anything new about the accelerator concept?16:14
_florent_DerekKozel[m]: Not directly on the concept but indirectly on the cores/components yes. 16:51
_florent_DerekKozel[m]: There is also https://github.com/enjoy-digital/xtrx_julia that could be interested where we are progressively re-creating a gateware for the XTRX16:52
_florent_DerekKozel[m]: P2PDMA has also been tested with LitePCIe to transfer samples directly from/to GPUs and do the processing there16:52
_florent_DerekKozel[m]: And I added 64-bit support to LitePCIe DMA for this (but only for 64-bit data-paths for now, so up to PCIe Gen2 X2)16:53
DerekKozel[m]Ok. I talked with the Julia folks at the start of the year and they have a talk at FOSDEM. 17:22
DerekKozel[m]I was thinking of picking up the CLE-215 again this weekend and updating the LitePCIe interface in GNU Radio to the latest on both sides17:23

shorneyay, I think I fixed the mor1kx dcache bug22:48
shorneIt took about a month to rewrite the formal verification to the point where 1. I could understand the workings of the load-store-unit enough and 2. I could use the formal verification to reproduce the dcache bug22:50
shorneafter that the fix was trivial, but having the formal verification + other regression testing in place to be able to give me confidence the fix is not introducing bugs was the key22:51
