Just one of the powerpc configs (pseries_defconfig which should, in theory, build a kernel that will boot on almost all our POWER server machines) loses all these drivers if you do a "make pseries_defconfig": -CONFIG_IBMVETH=y -CONFIG_PCNET32=y -CONFIG_E100=y -CONFIG_ACENIC=m -CONFIG_ACENIC_OMIT_TIGON_I=y -CONFIG_E1000=y -CONFIG_E1000E=y -CONFIG_BNX2=m -CONFIG_CHELSIO_T3=m -CONFIG_CHELSIO_T4=m -CONFIG_IXGBE=m -CONFIG_IXGB=m -CONFIG_S2IO=m -CONFIG_MYRI10GE=m -CONFIG_NETXEN_NIC=m -CONFIG_QLGE=m -CONFIG_BE2NET=m That is just one of our deconfigs ... there are over 400 defconfigs in the kernel and a lot of them will need to be updated. Mikey asks: Will Dave take these updates if we get Acks from the maintainers? :-) -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
