printk only works for "registered consoles." Currently, the hvc_console code calls register_console() from hvc_instantiate(), but that's only used in the early console case. In hvc_alloc(), register_console() was not called. Add a call to register_console() in hvc_alloc(), set up the index in the hvc_console, and set up the necessary vtermnos[] and cons_op[] entries so that printk functions work. Signed-off-by: Miche Baker-Harvey <miche@google.com> --- However, I'm not sure how this is supposed to be working, and not at all sure how this should tie in with command line selection of the console, or if there are other related issues I may have missed. I'd really appreciate your comments. --- drivers/tty/hvc/hvc_console.c | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-)
