From c5d2cac0f1caaf7dd21350146fb29c55b3e74249 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 23 May 2016 16:26:20 -0700 Subject: kgdb: depends on VT With VT=n, the kernel build fails with: drivers/built-in.o: In function `kgdboc_pre_exp_handler': kgdboc.c:(.text+0x7b5aa): undefined reference to `fg_console' kgdboc.c:(.text+0x7b5ce): undefined reference to `vc_cons' kgdboc.c:(.text+0x7b5d5): undefined reference to `vc_cons' kgdboc.o is built when KGDB_SERIAL_CONSOLE is set. So make KGDB_SERIAL_CONSOLE depend on HW_CONSOLE which includes those symbols.
