I There is a minor problem when we compile a Linux driver. Linux drivers use jiffies to measure time. Unfortunately, Mach doesn't provide it, so whenever we need it, we need to calculate it by ourselves. I decide to provide a macro to calculate it for the sake of performance and the cost is that the source code of Linux drivers has to include ddekit/timer.h. +## Build and run DDE drivers + +To build a Linux driver with DDE Linux, the easiest way is to use dde_pcnet32 (also in the dde branch) as a template. The directory of dde_pcnet32 has Makefile, Makeconf.local, default.ld, pcnet32.c and main.c. If we need to build a new driver file, we only need to replace pcnet32.c with the new file and change Makefile accordingly. + +To run a DDE NIC driver: + +settrans -acfg pcnet32 hurd/dde_pcnet32/dde_pcnet32 +settrans -acfg /dev/eth0 hurd/devnode/devnode eth0 -M pcnet32 +settrans -acfg /servers/socket/2 hurd/pfinet/pfinet -i /dev/eth0 -a 172.16.172.10 -g 172.16.172.2 -m 255.255.255.0 + --- #Project: Network virtualization for subhurds etc. |
