Don't keep the borders for non-fullscreen modes in XDR memory: - Extract ps3fb_sync_image() - Work around the alignment restrictions of L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT by using an offset with L1GPU_CONTEXT_ATTRIBUTE_DISPLAY_FLIP - Only copy the visible part of the screen on every vblank - Always put the real frame buffer at the start of video memory - Clear fullscreen DDR memory on mode change Signed-off-by:Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: "Antonino A.

ps3fb: Use fb_info.par properly: o Move mode-specific fields into struct ps3fb_par o Allocate struct ps3fb_par using framebuffer_alloc() o Protect access to ps3fb_par in ps3fb_sync() using the console semaphore (this semaphore is already held when ps3fb_set_par() is called) o Avoid calling ps3av_set_video_mode() if the actual video mode hasn't changed Signed-off-by: -

ps3fb: In the case of non-fullscreen video modes, there was a partial overlap of the GPU command buffer and the frame buffer. Fix and cleanup various issues with overlap and alignment: - Move the GPU command buffer from the beginning to the end of video memory - Exclude the GPU command buffer from the actual frame buffer memory - Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64 KiB, and don't waste memory if it's already aligned (for fullscreen modes) - Take into account the alignment when checking memory requirements and maximum number of frames - Make sure fb_fix_screeninfo.smem_start always points to the virtual frame buffer start, so we don't have to compensate for that in ps3fb_mmap() Signed-off-by: -

The i.MX frame-buffer read operation should be faster for all configurations then drawing each individual character again in response to scroll events. The nonstandard fields allows to configure frame-buffer special options flags for different display configurations by board specific initialization code. One of such specific options is reversed order of pixels in each individual byte. i.MX frame-buffer seems to be designed for big-endian use first. The byte order is correctly configured for little-endian ordering, but if 1, 2 or 4 bits per pixel are used, pixels ordering is incompatible to Linux generic frame-buffer drawing functions. The patch "Allow generic BitBLT functions to work with swapped pixel order in bytes" introduces required functionality into FBDEV core. The pixels ordering selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE and for each display configuration which requires it by flag FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure. This patch provides way for board specific code to select this option. Signed-off-by:

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:

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.

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:
