Disabling it significantly reduced code size for me. Since the series is more stable now, it is not really needed, so I disabled it in the defconfig. I was just fiddling with CONFIG_UNIX98_PTYS. Disabling it is OK with the simple busybox userspace (no telnet/xterm like app running). But it saves only about 1KB with my toolchain (gcc 9.3). So I left that one enabled. I am surprised that you see 16K size impact... How big is your image ? For me, it is 1.768 MB right now for the sdcard defconfig, with CONFIG_VT disabled and ext2 enabled. Disabling the block layer, ext2 and mmc driver, the size goes down to 1.511 MB without any intramfs cpio file embedded. > > [1] https://github.com/geertu/linux-scripts/blob/master/linux-analyze-marginal-sizes Thanks !

It might depend on how you measure. "size" says 15 KiB impact for UNIX98 ptys, while bloat-o-meter reported less than 7 (my script uses "size"). I'm at 1.88 MiB, with ext4 and without frame pointers. I also got rid of the EFI partition support, and a few I/O schedulers: +CONFIG_PARTITION_ADVANCED=y +# CONFIG_EFI_PARTITION is not set +# CONFIG_MQ_IOSCHED_DEADLINE is not set +# CONFIG_MQ_IOSCHED_KYBER is not set Gr{oetje,eeting}s, Geert

I look at the size of the arch/riscv/boot/loader.bin file since that is what gets loaded in RAM and booted. It is significantly smaller than vmlinux file size. E.g. for the sd card defconfig, I have: vmlinux: 2369920 B loader.bin: 1751250 B > I'm at 1.88 MiB, with ext4 and without frame pointers. > I also got rid of the EFI partition support, and a few I/O schedulers: > > +CONFIG_PARTITION_ADVANCED=y > +# CONFIG_EFI_PARTITION is not set > +# CONFIG_MQ_IOSCHED_DEADLINE is not set > +# CONFIG_MQ_IOSCHED_KYBER is not set I have all of these disabled. The schedulers are forced disabled in the sdcard defconfig. I also noticed that it hugely depend on the compiler. Using the buildroot generated rv64 gcc 10, the kernel image goes up to almost 2 MB. So for the kernel, I keep using the bootlin precompiled gcc 9.3: https://toolchains.bootlin.com/ Just noticed that they now have a 10.2 version available.

There is no need to enable Virtual Terminal support in the Canaan Kendryte K210 defconfigs, as no terminal devices are supported and enabled. Hence disable CONFIG_VT, and remove the no longer needed override for CONFIG_VGA_CONSOLE. This reduces kernel size by ca. 65 KiB.
