Public bug reported:
Some drivers in Ubuntu are built as kernel built-in components, not
allowing some module interesting features like blacklist on boot
command-line or module removal/replacement. Also, modules has debug
advantages compared to built-in kernel components, like the possibility
to easy build custom-debug modules against kernel tree and replace them
using modprobe on running system.
This feature is a request to Canonical move some currently built-in
drivers to module build system on Power platform, by changing the kernel
config file.
The drivers in question are: tg3, virtio-blk and virtio-net.
The kernel config file parameters related to those 3 drivers are:
CONFIG_TIGON3, CONFIG_VIRTIO_BLK and CONFIG_VIRTIO_NET.
They all are currently set as "=y"; we're requesting a change to "=m".
Thanks in advance,
Guilherme
