74f482cca5 fb: nvidiafb: Try harder at initial mode setting.
The current nvidiafb_check_var() simply bails out if the selected mode is
out of range of the panel dimensions.  A good question would be why the
bogus mode is being selected in the first place -- the panel dimensions
that are read back are certainly bogus, but alas, I have no idea where to
even begin looking at the i2c/EDID/DDC mess:

nvidiafb: Device ID: 10de0165
nvidiafb: CRTC0 analog not found
nvidiafb: CRTC1 analog not found
nvidiafb: EDID found from BUS1
nvidiafb: CRTC 0 is currently programmed for DFP
nvidiafb: Using DFP on CRTC 0
nvidiafb: Panel size is 1280 x 1024
nvidiafb: Panel is TMDS
nvidiafb: unable to setup MTRR
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000)

In my .config I presently have:

CONFIG_FIRMWARE_EDID=y
CONFIG_FB_DDC=y
CONFIG_FB_NVIDIA_I2C=y

I've not tried fiddling with these options, as I haven't the vaguest idea
what I should be looking at.

As a workaround, simply groveling for a new mode based on the probed
dimensions seems to work ok.  While it would be nice to debug this further
and sort out why the panel information is bogus, I think it's still worth
retrying the mode based on the panel information at hand as a last-ditch
effort, rather than simply bailing out completely.

2e9750272c vermilion.c: use ALIGN(), not __ALIGN_MASK()
__ALIGN_MASK() is an internal implementation detail of ALIGN().  Let's not
needlessly fatten the interface in this driver.

0e9045494a neofb: avoid overwriting fb_info fields
Fix bug identified by Marcio Buss in
http://bugzilla.kernel.org/show_bug.cgi?id=9565 - neofb can overwrite a field
in the fb_info struct.

This fix will result in truncated device identification strings - perhaps
fb_innfo.fix.id can be made larger?

a10336043b s3c2410_fb: fix line length calculation
Fix line length calculation. var->width is the size of the display in mm. We
like to use the pixel size.

Without this fix, dynamic (fbset) based resolution and depths changes with
s3c2410_fb don't work at all.

545c442333 fix radeonfb regression with Xpress 200m 5955
Fix http://bugzilla.kernel.org/show_bug.cgi?id=9762

Framebuffer is ok only with default parameters only (it is 1280x800-8@60).  If
parameters are video=radeonfb:1280x800-32@60 then xres, yres and xres_virtual
are ok but yres_virtual is 1024.  It can be corrected by fbset utility so I
think it can be corrected in the driver code also.

Steps to reproduce: video=radeonfb:1280x800-32@60 or
video=radeonfb:1280x800-16@60

Add 1280x800 mode into modedb

8dab637612 ps3fb: fix deadlock on kexec()
Since the introduction of the acquire_console_sem calls in
0333d83509, kexecing can cause the
kernel to deadlock:

 ps3fb_shutdown()
  -> unregister_framebuffer()
  -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND)
  -> fbcon_fb_unbind()
  -> unbind_con_driver()
  -> bind_con_driver()
	[ acquires console_sem ]
  -> fbcon_deinit()
  -> fbops->fb_release(newinfo, 0)
  -> ps3fb_release()
  -> ps3fb_sync()
	[ acquires console_sem ]

This change avoids the deadlock by moving the acquire_console_sem()
out of ps3fb_sync(), and puts it into the two other callsites, leaving
ps3fb_release() to call ps3fb_sync() without the console semaphore.

[Geert]
  - Corrected call sequence above
  - ps3fb_release() may be called with and without console_sem held. This is an
    inconsistency that should be fixed at the fb level, but for now, try to
    acquire console_sem in ps3fb_release().

    I think it's safer to let ps3fb_release() try to acquire console_sem and
    not refresh the screen if it fails, than to call ps3fb_sync() without
    holding console_sem, as ps3fb_par may be modified at the same time, causing
    crashes or lockups.

    Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen
    when display flipping is disabled, which is an uncommon case (except during
    shutdown/kexec).

ba21611c9c ps3fb: prevent use after free of fb_info
In ps3fb_shutdown, freeing the framebuffer will cause fb_info (in

from the ps3fbd kthread.

This change frees the framebuffer after stopping the ps3fbd kthread.

As of PS3 firmware version 2.10, the GPU command buffer size must be at least 2
MiB large. Since we use only a small part of the GPU command buffer and don't
want to waste precious XDR memory, move the GPU command buffer back to the
start of the XDR memory reserved for ps3fb and let the unused part overlap with
the actual frame buffer.

7c83172b98 x86_64 EFI boot support: EFI frame buffer driver
This patch adds Graphics Output Protocol support to the kernel.  UEFI2.0 spec
deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output
Protocol (GOP) is produced.  Therefore, the boot loader needs to query the
UEFI firmware with appropriate Output Protocol and pass the video information
to the kernel.  As a result of GOP protocol, an EFI framebuffer driver is
needed for displaying console messages.  The patch adds a EFI framebuffer
driver.  The EFI frame buffer driver in this patch is based on the Intel Mac
framebuffer driver.

The ELILO bootloader takes care of passing the video information as
appropriate for EFI firmware.

The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI
platform.

e593f070b4 atmel_lcdfb: LCDC startup fix
This patch adds an additional loop, that delays turning off the DMA
until the LCDC core has been turned off. This prevents the picture
to be shifted some random length when the kernel re-initializes
the LCDC.

Without this patch, the LCDC keeps running for some small time after the
PWRCON:LCD_PWR has been cleared ; the FIFO suffers an underrun and on
re-starting the LCDC the FIFO data stays shifted.

This behavior has been seen and fixed on AT91SAM9261-EK and two custom
AT91SAM9261 boards, all of them having different LCD panels.

Thanks a lot to Anti Sullin for submitting this patch (long
time ago).

b64d70825a fb_ddc: fix DDC lines quirk
The code in fb_ddc_read() is said to be based on the implementation of the
radeon driver:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc5891c8a3ba284f13994d7bc1f1bfa8283982de

However, comparing the old radeon driver code with the new fb_ddc code
reveals some differences.  Most notably, the I2C bus lines are held at the
end of the function, while the original code was releasing them (as the
comment above correctly says.)

There are a few other differences, which appear to be responsible for read
failures on my system.  While tracing low-level I2C code in i2c-algo-bit, I
noticed that the initial attempt to read the EDID always failed.  It takes
one retry for the read to succeed.  As we are about to remove this
automatic retry property from i2c-algo-bit, reading the EDID would really
fail.

As a summary, the I2C lines quirk which is supposedly needed to read EDID
on some older monitors is currently breaking the (first) read on all other
monitors (and might not even work with older ones - did anyone try since
October 2006?)

After applying the patch below, which makes the code in fb_ddc_read()
really similar to what the radeon driver used to have, the first EDID read
succeeds again.

On top of that, as it appears that this code has been broken for one year
now and nobody seems to have complained, I'm curious if it makes sense to
keep this quirk in place.  It makes the code more complex and slower just
for the sake of monitors which I guess nobody uses anymore.  Can't we just
get rid of it?
