2008-07-24vfb: only enable if explicitly requested when compiled inFrans Pop1-2/+12
The Kconfig help for the vfb driver says: Do NOT enable it for normal systems! To protect the innocent, it has to be enabled explicitly at boot time using the kernel option `video=vfb:'. This change lets the code match the description. Support for vfb:disable is kept for backwards compatibility; vfb:off works because it is tested at a higher level. Note: any undefined option (e.g. vfb:enable) will also enable this driver. The relevant code has been unchanged since before the migration to git (2.6.12). This patch fixes bugzilla #9310 and was the root cause behind http://lkml.org/lkml/2008/5/31/220. Signed-off-by: Frans Pop <elendil@planet.nl> Cc: Antonino A.

2007-10-16vfb: make virtual framebuffer mmapableIlya Yanok1-4/+74
Changed things: 1. vmalloc()/vfree() replaced with rvmalloc()/rvfree() (taken from drivers/media/video/se401.c) 2. mmap method implemented (mostly taken from drivers/media/video/se401.c) 3. smem_start and smem_len fields of struct fb_fix_screeninfo initialized. (smem_start initialized with virtual address, don't know if it is really bad...)

2006-07-10[PATCH] vt: Remove VT-specific declarations and definitions from tty.hJon Smirl1-1/+0
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.

2005-11-09[DRIVER MODEL] Convert platform drivers to use struct platform_driverRussell King1-11/+11
This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas1-1/+0
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+528
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
