fbdev: remove the unnecessary includes of ppc specific header files

2015-03-17T09:04:32+00:00

In the current kernel, we don't need to include these arch specific
header files for ppc.

video: fbdev: fix possible null dereference

2015-02-26T08:23:15+00:00

we were dereferencing edid first and the NULL check was after
accessing that. now we are using edid only if we know that
it is not NULL.

video: fbdev: fix sys_copyarea

2015-01-30T07:46:59+00:00

The sys_copyarea() function performs the same operation as
cfb_copyarea() but using normal memory access instead of I/O
accessors.  Since the introduction of sys_copyarea(), there
have been two fixes to cfb_copyarea():

- 00a9d699 ("framebuffer: fix cfb_copyarea")
- 5b789da8 ("framebuffer: fix screen corruption when copying")

This patch incorporates the fixes into sys_copyarea() as well.

fbdev: fix CVT vertical front and back porch values

2015-01-27T11:35:37+00:00

CVT v1.1 spec says: "the vertical front porch shall in all cases be
fixed to 3 lines". The code in fbcvt.c instead sets the _back_ porch to
3 (plus margin).

After swapping cvt.v_front_porch and cvt.v_back_porch the resulting
timings were in line with CVT timings in VESA DMT spec.

The bug seems to be more than 9 years old, but I presume it has not been
noticed as usually the video timings come from the EDID or from the
timing tables in fbdev, and probably swapped values for vfp and vbp work
fine for most of the displays.

video: fbdev: Validate mode timing against monspec

2015-01-15T11:33:41+00:00

fbmon may generate mode timings that are out of spec of the monitor.
eg DELL U2410 has a max clock 170mhz but advertises a resolutions of
1920x1200@60 in its Standard Timings using 2byte code of D1 00.
When this is looked up in the DMT table it gives it a 193mhz clock.
Although the DELL monitor supports 1920x1200@60, it can only run with
reduced timings at 154mhz or DMT id 0x44 which has no STD 2byte code.
This patch checks to see if the mode can be supported by the monitor
by comparing against monspecs.dclkmax.

video: fbdev: Check Standard Timing against DMT

2015-01-15T11:33:41+00:00

Add the VESA Display Monitor Timing (DMT) table.
During parsing of Standard Timings, it compare the 2 byte STD code
with DMT to see what the VESA mode should be.  If there is no entry
in the vesa_modes table or no match found, it fallsback to the
GTF timings.

video/fbdev: fix defio's fsync

2014-12-30T09:18:30+00:00

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().
