In /etc/inittab, there's a line related to this: 1:2345:respawn:/sbin/getty 38400 tty1 But there's no /dev/tty1 file. Command: ls /dev/tty? Result: /dev/tty0 25173 1 dvhart 2012-09-13 14:40:09 +0000 Bruce, do we know what changed here? Was the tty1 line added to inittab? Have we changed the console/vt settings in the kernel config? What about devtmpfs? 25208 2 bruce.ashfield 2012-09-13 17:08:25 +0000 There are no kernel or kernel config changes that I can think of that would have spawned (pun intended) the problem. Can someone confirm that this hasn't always been happening since we bumped the kernel version to 3.4 for the board ? 25235 3 Qi.Chen 2012-09-14 05:37:56 +0000 It seems that this problem is caused by the kernel verion bumping (from 3.0 to 3.4). Here's some detail. 20120819 image from autobuilder has no such problem. http://autobuilder.yoctoproject.org/pub/nightly/20120819-2/machines/routerstationpro/ Git Hash: d7a6aafea3c76dd8acea5e3b93833c4f521e5290 Git Branch: poky/master root@routerstationpro:~# uname -r 3.0.32-yocto-standard root@routerstationpro:~# ls /dev/tty? /dev/tty0 /dev/tty2 /dev/tty4 /dev/tty6 /dev/tty8 /dev/tty1 /dev/tty3 /dev/tty5 /dev/tty7 /dev/tty9 root@routerstationpro:~# grep -i respawn /etc/inittab z6:6:respawn:/sbin/sulogin S:2345:respawn:/sbin/getty 115200 ttyS0 1:2345:respawn:/sbin/getty 38400 tty1 20120822 image from autobuilder has this problem. http://autobuilder.yoctoproject.org/pub/nightly/20120822-1/machines/routerstationpro/ Git Hash: 19ff55a53b436d463f9577adaed15be77708f0d2 Git Branch: poky/master root@routerstationpro:~# ls /dev/tty? /dev/tty0 root@routerstationpro:~# grep -i respawn /etc/inittab z6:6:respawn:/sbin/sulogin S:2345:respawn:/sbin/getty 115200 ttyS0 1:2345:respawn:/sbin/getty 38400 tty1 root@routerstationpro:~# uname -r 3.4.7-yocto-standard INIT: Id "1" respawning too fast: disabled for 5 minutes 25236 4 Qi.Chen 2012-09-14 05:59:13 +0000 I looked into the /proc/config.gz file in both images (20120819 and 20120822). There's no virtual console configuration item in kernel 3.4 (20120822 build). zcat config.gz | grep -i console CONFIG_NETCONSOLE=y CONFIG_SERIAL_8250_CONSOLE=y CONFIG_SERIAL_CORE_CONSOLE=y CONFIG_CONSOLE_POLL=y CONFIG_KGDB_SERIAL_CONSOLE=y On the other hand, CONFIG_VT_CONSOLE is enabled in kernel 3.0 (20120819 build). zcat config.gz | grep -i console CONFIG_NETCONSOLE=y # CONFIG_NETCONSOLE_DYNAMIC is not set CONFIG_CONSOLE_TRANSLATIONS=y CONFIG_VT_CONSOLE=y CONFIG_HW_CONSOLE=y # CONFIG_VT_HW_CONSOLE_BINDING is not set CONFIG_SERIAL_8250_CONSOLE=y CONFIG_SERIAL_CORE_CONSOLE=y # Console display driver support CONFIG_VGA_CONSOLE=y CONFIG_DUMMY_CONSOLE=y 25312 5 dvhart 2012-09-17 17:42:21 +0000 CONFIG_VT_CONSOLE=y should be part of yocto/standard (but not tiny). This might be a missing standard policy option. Having a look. 25313 6 dvhart 2012-09-17 17:47:46 +0000 For the 3.4 kernel, both config VT and config VT_CONSOLE are "default y". Although the only explicit inclusion of this in the linux-yocto meta dir is for the qemu-platform. Various defconfig set this to y, and one to "is not set". Bruce, are we pulling in a linux platform defconfig for the mips platform in addition to what is in meta? 25314 7 dvhart 2012-09-17 17:52:33 +0000 Oh, oops, I missed this: bsp/routerstationpro/routerstationpro.cfg:# CONFIG_VT is not set $ git blame -L 64,65 bsp/routerstationpro/routerstationpro.cfg afe856e0 (Paul Gortmaker 2012-07-19 16:22:12 -0400 64) # CONFIG_VT is not set afe856e0 (Paul Gortmaker 2012-07-19 16:22:12 -0400 65) # CONFIG_INPUT is not set commit afe856e02ef6dcface4f74d094285e1f8524b5a0 Author: Paul Gortmaker <paul.gortmaker@windriver.com> Date: Thu Jul 19 16:22:12 2012 -0400 routerstationpro: Add a config fragment Unlike the previous config, this is a more minimalistic one that sticks to just specifying hardware items. The watchdog minifrag gets an update too, as a config option got renamed. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> So this is being explicitly disabled for this BSP. Paul, was this deliberate or accidental? 25315 8 dvhart 2012-09-17 17:54:13 +0000 Chen, can you remove the CONFIG_VT line from the routerstationpro.cfg and rebuild the kernel. Does that resolve the problem? 25316 9 paulg 2012-09-17 18:19:59 +0000 > Paul, was this deliberate or accidental? Deliberate. It only has a serial console. There is nothing resembling a visual or HID I/O interface/device on this thing. Re-enabling CONFIG_VT will of course "solve" the problem, but that is not (IMO) the right fix. The rootfs should be intelligent enough (or manually tuned) to not have an always-spawn-getty-on-tty1 mentality. This thing has a low amount of memory, and enabling Kconfigs (and running extra userspace cruft) is hence not the right approach. 25327 10 Qi.Chen 2012-09-18 05:40:43 +0000 I looked into meta/recipes-core/sysvinit/sysvinit-inittab_2.88dsf.bb, and I noticed that this file has already take this issue into consideration. Following's a piece of code dealing with VT configuration in inittab: if [ "${USE_VT}" = "1" ]; then # write virtual terminal configs into inittab 25328 11 Qi.Chen 2012-09-18 05:44:37 +0000 I looked into meta/recipes-core/sysvinit/sysvinit-inittab_2.88dsf.bb, and I noticed that this file has already taken this issue into consideration. Following's a piece of code dealing with VT configuration in inittab: if [ "${USE_VT}" = "1" ]; then # write virtual terminal configs into inittab fi So I think just adding a line to meta-yocto-bsp/conf/machine/routerstationpro.conf would fix this. diff --git a/meta-yocto-bsp/conf/machine/routerstationpro.conf b/meta-yocto-bsp/conf/machine/routerstationpro.conf index 707392d..2b174e8 100644 --- a/meta-yocto-bsp/conf/machine/routerstationpro.conf +++ b/meta-yocto-bsp/conf/machine/routerstationpro.conf @@ -19,6 +19,7 @@ XSERVER ?= "xserver-xorg \ xf86-video-fbdev" SERIAL_CONSOLE = "115200 ttyS0" +USE_VT = "0" MACHINE_EXTRA_RRECOMMENDS = " kernel-modules" But I don't know whether it is appropriate to do so. 25334 12 dvhart 2012-09-18 07:59:57 +0000 That looks right to me.
