fbcon: Remove unused vblank cursor code

2015-01-26T12:10:37Z

commit 1fa0b29f3a43 ("fbdev: Kill Atari vblank cursor blinking") rendered vbl_cursor_cnt and therefore CURSOR_DRAW_DELAY unused in fbcon.c, so remove them. Signed-off-by: Scot Doyle Signed-off-by: Tomi Valkeinen

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

2015-01-13T12:54:48Z

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

fbcon: Change fbcon_init from module_init to fs_initcall

2014-11-14T13:29:11Z

Various fb drivers register themselves before module_init so as to have a console as early as possible, this is of little use if fbcon does not initialize early too. Fbcon cannot initialize earlier then fs_initcall, because then the creation of /sys/class/graphics/fbcon will fail. Signed-off-by: Hans de Goede Signed-off-by: Tomi Valkeinen

video/console: Resolve several shadow warnings

2014-10-22T06:56:41Z

Resolve shadow warnings that appear in W=2 builds by renaming the "state" global to "vgastate". Signed-off-by: Mark Rustad Signed-off-by: Jeff Kirsher Signed-off-by: Tomi Valkeinen

fbcon: Fix option parsing control flow in fb_console_setup

2014-10-22T06:49:40Z

Since strsep is used to tokenize the options string, after each option match the code should use "continue" to get the next token from strsep. This patch applies this pattern consistently. Previously, for "scrollback:" and "map:" the parse code would return (unconditionally: strsep ensures *options != ','), causing any following option to be ignored, while for "vc:" the parse code would go on to parse further options within the same token, which could lead to invalid input being accepted.

framebuffer: fix border color

2014-09-30T10:39:16Z

The framebuffer code uses the current background color to fill the border when switching consoles, however, this results in inconsistent behavior. For example: - start Midnigh Commander - the border is black - switch to another console and switch back - the border is cyan - type something into the command line in mc - the border is cyan - switch to another console and switch back - the border is black - press F9 to go to menu - the border is black - switch to another console and switch back - the border is dark blue When switching to a console with Midnight Commander, the border is random color that was left selected by the slang subsystem. This patch fixes this inconsistency by always using black as the background color when switching consoles. Signed-off-by: Mikulas Patocka Cc: stable@vger.kernel.org Signed-off-by: Tomi Valkeinen

drm/i915: Kick out vga console

2014-06-09T19:03:47Z

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.

console: Use explicit pointer type for vc_uni_pagedir* fields

2014-05-28T20:37:21Z

The vc_data.vc_uni_pagedir filed is currently long int, supposedly to be served generically. This, however, leads to lots of cast to pointer, and rather it worsens the readability significantly. Actually, we have now only a single uni_pagedir map implementation, and this won't change likely. So, it'd be much more simple and error-prone to just use the exact pointer for struct uni_pagedir instead of long. Ditto for vc_uni_pagedir_loc. It's a pointer to the uni_pagedir, thus it can be changed similarly to the exact type. Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman
