console/dummy: leave .con_font_get set to NULL

2018-01-15T16:04:22+00:00

When this method is set, the caller expects struct console_font fields to be properly initialized when it returns. Leave it unset otherwise nonsensical (leaked kernel stack) values are returned to user space. Signed-off-by: Nicolas Pitre Cc: stable@vger.kernel.org Signed-off-by: Bartlomiej Zolnierkiewicz

tty: vt, remove consw->con_bmove

It is never called since commit 81732c3b2fede (tty vt: Fix line garbage in virtual console on command line edition) in 3.7. So remove all the callbacks.

console/dummy: Move screen size selection from CPP to Kconfig

2015-01-13T12:54:48+00:00

PA-RISC already handled the dummy console screen size selection in Kconfig, so generalize this to other platforms. ARM keeps on using screen_info, which is filled in by platform-specific code, or from ATAGS. Signed-off-by: Geert Uytterhoeven Signed-off-by: Tomi Valkeinen

drm/i915: Kick out vga console

2014-06-09T19:03:47+00:00

Touching the VGA resources on an IVB EFI machine causes hard hangs when we then kick out the efifb. Ouch. Apparently this also prevents unclaimed register errors on hsw and hard machine hangs on my i855gm when trying to unbind fbcon. Also, we want this to make I915_FBDEV=n safe. v2: Rebase and pimp commit message. v3: We also need to unregister the vga console, otherwise the unbind of the fb console before module unload might resurrect it again. v4: Ignore errors when the vga console is already unregistered - this can happen when e.g. reloading i915.ko.

[PATCH] tty: Remove include of screen_info.h from tty.h

2006-07-10T20:24:16+00:00

screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.

[PATCH] vt: Remove VT-specific declarations and definitions from tty.h

2006-07-10T20:24:16+00:00

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h.
