For most other firmware files, we have more fine grained options. When
I look at the nvidia/ folder, it has firmware for various graphics
cards:
gk20a
gm200
gm204
gm206
gm20b
gp100
gp102
gp104
gp106
gp107
gp108
gp10b
gv100
tegra124
tegra186
tegra194
tegra210
tu102
tu104
tu106
tu10x
Size-wise, it goes like this:
116K ./gm200
96K ./gp107
36K ./gp106
44K ./gm206
120K ./gp100
28K ./gm204
340K ./tu10x
148K ./tegra210
116K ./gp108
128K ./tegra194
164K ./gm20b
68K ./gk20a
368K ./gp102
276K ./gv100
128K ./tu106
128K ./tu104
148K ./tegra186
76K ./gp104
196K ./gp10b
272K ./tu102
152K ./tegra124
3,1M .
So, in practice, on a given platform, you would typically need only
100-200 KB of firmware on the total 3.1 MB.
Best regards,
Thomas
