2014-12-30video/fbdev: fix defio's fsyncTomi Valkeinen1-2/+3
fb_deferred_io_fsync() returns the value of schedule_delayed_work() as an error code, but schedule_delayed_work() does not return an error. It returns true/false depending on whether the work was already queued. Fix this by ignoring the return value of schedule_delayed_work().

2014-09-30framebuffer: fix screen corruption when copyingMikulas Patocka1-5/+8
The function bitcpy_rev has a bug that may result in screen corruption. The bug happens under these conditions: * the end of the destination area of a copy operation is aligned on a long word boundary * the end of the source area is not aligned on a long word boundary * we are copying more than one long word In this case, the variable shift is non-zero and the variable first is zero. The statements FB_WRITEL(comp(d0, FB_READL(dst), first), dst) reads the last long word of the destination and writes it back unchanged (because first is zero). Correctly, we should write the variable d0 to the last word of the destination in this case. This patch fixes the bug by introducing and extra test if first is zero. The patch also removes the references to fb_memmove in the code that is commented out because fb_memmove was removed from framebuffer subsystem.

Instead of dereference each byte let's use %*ph specifier in the printk() calls. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-08-06video/fbdev: Always built-in video= cmdline parsingDaniel Vetter4-95/+111
In drm/i915 we want to get at the video= cmdline modes even when we don't have fbdev support enabled, so that users can always override the kernel's initial mode selection. But that gives us a direct depency upon the parsing code in the fbdev subsystem. Since it's so little code just extract these 2 functions and always build them in. Whiel at it fix the checkpatch fail in this code. v2: Also move fb_mode_option. Spotted by the kbuild. v3: Review from Geert: - Keep the old copyright notice from fb_mem.c, although I have no idea what exactly applies. - Only compile this when needed.

2014-05-09video: export fb_prepare_logoArnd Bergmann1-0/+1
Some drivers that may be loadable modules use the fb_prepare_logo function, so we have to export it. Found during randconfig builds with mmpfb.

2014-04-17fbdev: move fbdev core files to separate directoryTomi Valkeinen19-0/+9565
Instead of having fbdev framework core files at the root fbdev directory, mixed with random fbdev device drivers, move the fbdev core files to a separate core directory. This makes it much clearer which of the files are actually part of the fbdev framework, and which are part of device drivers.
