I know from experience that it's not possible on x86 especially with efifb in the mix, but I wonder what the situation on ARM is. I only have TI, sunxi and exynos boards to test on and building in both TI drm drivers and the exynos one seems to work. > Note that I'm not talking about the non-DRM abortions that maskerade as graphics drivers for ARM SoCs, only proper DRM ones. > > regards, > > Koen A quick check tells me that my current sunxi-3.4 sunxi_drm.ko measures 1.7MB, for currently about 8kloc (the binary seems excessively big though), which is just display. This still lacks many key features (lcd gpio, backlight pwm, lvds, ints), so it will grow ~1kloc still. Also, i constantly am re-loading this (how else does one develop any sizable amount of code?), so it does that cleanly and correctly, which seems quite contrary to your experience with ARM drm drivers.
