Good day to all! bfe driver ported as client of siba bus, it`s worked, but work not done. To dirty code :) Question to FreeBSD MIPS guru: Maybe problem in me low experience in FreeBSD internals, but I thing bus_dmamem_alloc and bus_dmamem_load ignore "alignment" attribute passed to bus_dma_tag_create. BFE need DMA descriptors page to be aligned to 4096, but I done this alignment only with set descriptors count from 128 to 512 Next question, how I can start init (without "write fault at 0x2003821"), if someone know boot -tftp -raw -addr=0x807963c0 -max=0x770000 192.168.0.90:kernel.tramp.bin cmd = boot -tftp -raw -addr=0x807963c0 -max=0x770000 192.168.0.90:kernel.tramp.bin Loader:raw Filesys:tftp Dev:eth0 File:192.168.0.90:kernel.tramp.bin Options:(null) Loading: entry point=807963C0 ...... 3773973 bytes read Entry at 0x807963c0 Closing network.
