To add your driver you update the src/sys/conf/files* files. If your driver is machine independent, you can add it to src/sys/conf/files. For example, here are the lines in sys/conf/files for the cy(4) driver: dev/cy/cy.c optional cy dev/cy/cy_isa.c optional cy isa dev/cy/cy_pci.c optional cy pci If your driver only works on a single architecture (such as i386) then add it to the architecture file sys/conf/files.<arch> (e.g. sys/conf/files.i386). The device names after 'optional' specify which devices must be enabled in the kernel config for that file to be included. Thus, in the example above, src/sys/dev/cy/cy.c is included as long as 'device cy' is in the kernel, but src/sys/dev/cy/cy_isa.c is only included if both 'device cy' and 'device isa' are in the kernel config file. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
