Hi, I have a rather rough port of FreeBSD current on arm to Jetson TK1. I used Stephen Warren's tegra u-boot sources, which initialize and configure USB and PCIe.=20 So SMP, USB and the onboard PCIe Ethernet adapter work. After Ian's changes to busdma_machdep-v6 (r269212) I had problems with cache coherency with the Ethernet adapter. Seems this is due to the aggress= ive L2 prefetcher of Cortex A15. Disabling L2 prefetch does help, as well as invalidating the cache a second time after the dma transfer. I'm not sure what the correct solution to this problem is. I wonder how other Cortex A15 platforms (exynos5) handle this.=20 I will probably be able to do some cleanups and put patches on the web within a week.
