Various console drivers are able to resize the screen via the con_resize() hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that con_resize() of the VGA console will always return success even if the resulting screen is not compatible with the hardware. However, this particular behavior of the VGA console, as reported in Kernel Bugzilla Bug 7513, can cause undefined behavior if the user starts with a console size larger than 80x25. To work around this problem, add an extra parameter to con_resize(). This parameter is ignored by drivers except for vgacon. If this parameter is non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl and vgacon will always return success. If this parameter is zero, vgacon will return -EINVAL if the requested size is not compatible with the hardware. The latter is the more correct behavior. With this change, SVGATextMode should still work correctly while in-kernel and stty resize calls can expect correct behavior from vgacon. Signed-off-by:

Move video graphics driver configs to fix menus: Fix FB_PMAGB_B to depend on FB so that the FB menus remain listed in order and indented correctly. Fix FB_IBM_GXT4500 to depend on FB so that the FB menus remain listed in order and indented correctly. The OMAP FB drivers still muck up the FB menu a bit, so I put OMAP drivers at the end of the FB menu. Signed-off-by:

Add error messages to the probe call. While they may rarely trigger, they may be useful when something weird is going on. Also this is good style. [akpm@linux-foundation.org: remove unneeded initialisation] Signed-off-by:

Make radeonfb work ith the 200m Xpress RC410. In my tests it was terribly unstable and would freeze until I set a refresh rate in the kernel argument to 75. e.g video=radeonfb:1280x800@75 Now it is rock solid.

ps3fb: Add a `mode' parameter to ps3fb_get_res_table(), as in some cases it should check the full-screen flag of the _new_ video mode instead of the current video mode. This bug caused spurious mode change failures when switching between fullscreen and non-fullscreen modes using fbset, while ps3-video-mode worked fine. Signed-off-by:

Fix the black and white stripes issue with WUXGA monitor via HDMI. It seems that when we use a VESA resolution from boot up, the AV settings driver could not be initialized correctly. In that case we need a dummy packet before VESA setting. [Geert] Refactored to reduce code duplication. Signed-off-by:

Allow generic frame-buffer code to correctly write texts and blit images for 1, 2 and 4 bit per pixel frame-buffer organizations when pixels in bytes are organized to in opposite order than bytes in long type. Overhead should be reasonable. If option is not selected, than compiler should eliminate completely all overhead. The feature is disabled at compile time if CONFIG_FB_CFB_REV_PIXELS_IN_BYTE is not set. [adaplas] Convert helper functions to macros if feature is not enabled. Signed-off-by:

There are a few nvidia hardware where the i2c port assignments are reversed, i.e., the 1st i2c port is assigned to the secondary display and the 2nd i2c port to the primary display. In most cases, if only 1 display is attached, or if only 1 flatpanel and 1 analog display is attached, the port reversal is of no consequence. However if 2 flatpanels are attached, it can cause display problems. There is no sane way of determining if the hardware reversed the i2c port assignment, so the simplest fix is to add a boot/module option, "reverse_i2c to explicitly reverse the i2c port. This also restores i2c ordering back to the pre-2.6.22 state. Signed-off-by:

Currently, if the refresh rate is not specified, fb_find_mode() returns the first known video mode with the requested resolution, which provides no guarantees wrt the refresh rate. Change this so that the mode with the highest refresh rate is returned when the driver provides a custom video mode database and the monitor limits, and a mode with the safe 60 Hz refresh rate otherwise.

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...) [adaplas: sparse warning fix] Signed-off-by: -

This patch adds pixelclock field to the s3c2410fb_display structure and make use of it in the driver.

This patch sets correct bits related to the byte ordering of the framebuffer. This was tested on little endian kernel only. The big endian kernel may require different settings. The patch also adds 32 bpp mode which is called 24 bpp by Samsung. One pixel takes 32 bits but only 24 bits are used in this mode. Signed-off-by:
