So... I was wondering what the impact of splitting up the card compilation by
e.g. generation would be. Depending on the split things would get fairly
intertwined, so I thought I'd start small. This just splits NVC0 from
everything else. I figure that for the people this matters the most to, NVC0
is the least relevant card -- people with sub-1GB of RAM, older hardware.
With my config options and everything compiled, the total size of nouveau.ko
is 1343324 bytes (incl symbols), which is split up
text data bss dec hex filename
579171 184264 480 763915 ba80b ./drivers/gpu/drm/nouveau/nouveau.ko
Turning off nvc0+ gives us 995667 bytes, split up
text data bss dec hex filename
472244 59528 480 532252 81f1c ./drivers/gpu/drm/nouveau/nouveau.ko
So we lost 100K of text and 130K of data (probably all that pgraph fw), and
the remaining 100K must be symbols. (I'm not stripping because nobody in their
right mind strips these kernel modules.)
The impact to the code is pretty minor. Depending on the situation it's easier
to either ifdef out code or to provide stubs for functions.
What do people think about this? It shouldn't be too difficult for me to
extend this to categories like <pre-nv50> <nv50-nvc0> <nvc0-nve0> <nve0+>, or
maybe even more fine-grained, esp since nvd0 is when a lot of changes
happened. Or maybe less-fine-grained and keep the nvc0/nve0 cards under one
option.
Feedback appreciated.
