A slight oversight tripped lockdep debugging code, each lockdep class should have but a single init site. Rearange the code to make this true. Signed-off-by:

There is a test in tgafb_mono_imageblit() for a colour image with a fall-back to cfb_imageblit(). The test is not necessary as the only caller, which is tgafb_imageblit(), checks it too and only invokes this function for monochrome images. It looks like a left-over from before some changes to tgafb_imageblit(). Signed-off-by:

The pixel mask calculation in tgafb_mono_imageblit() uses a variable left-shift on a 32-bit data type by up to 32. Shifting by the width of a data type or more produces an unpredictable result according to the C standard. Rather than widening the data type this fix makes sure the count is between 0 and 31. The reason is not to penalise 32-bit platforms with operation on a "long long" type for a marginal case that is meant not to happen (blitting an image of a zero width). The reason it has escaped for so long is the Alpha, being purely 64-bit, :-) does not mask the shift out to 32 bits. This is a valid implementation -- producing the correct result certainly falls within "unpredictable behaviour". It does trigger on MIPS though and it is the recent merge of the TC support which only enabled the driver for use on anything other than the Alpha. For MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as it should be and the frame buffer is not updated. Signed-off-by:

As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular cursor can still be seen blinking in the upper left part of the screen. It is fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE, KD_TEXT) call done by something in userspace, perhaps by X itself, while the tty is still in graphics mode. And when the tty is in KD_TEXT mode, the cursor timer is restarted. Although this is a userspace problem, we can work around it by delaying the restart of the cursor timer until an fbcon_switch() is called. In other words, the cursor timer will not be restarted even if a KD_TEXT mode switch is requested. Regression potential: Present but low Signed-off-by:

This correct case, when source and destination X coordinates difference is n multiple of pixels in byte. This is probably rare case, but this case should supported for completeness. Reorganization of FB_READL and FB_WRITEL calls results in code size decrease for normal build without swapping support and size with support enabled is reasonable too. [adaplas] Add missing fb_rev_pixels_in_long() prototype. Signed-off-by:

This patch adds check if selected pixclock is valid (is in the PLL range). Previously, if the pixclock could not be set, the new mode resolution was set but pixclock was not set which led to incorrect timings sent to monitor. [adaplas] Fixed a few misplaced curly braces. Signed-off-by:

This patch changes mode selection matching algorithm. It allows to choose mode with matching depth even when requested color lengths are greater than color lengths of every mode with requested color depth. It also fixes bug in s3fb - wrong error value returned when format is not supported by chip. Signed-off-by:

Default to the 480p video mode on DVI-D and HDMI displays if `video=safe' is passed on the kernel command line. This is intended to be used by `kboot'-style boot loaders (i.e. first-stage kernels) for the PS3, to provide a failsafe video mode. Signed-off-by:

ps3fb: Enhance horizontal panning on firmware 1.90 and up: - On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying rectangles from XDR to DDR memory with different source and destination line lengths. Hence larger horizontal virtual resolutions can be supported (up to 16368 pixels). - As the actual frame buffer memory layout no longer matches the entries in ps3fb_res[], create fake struct ps3fb_ioctl_res data for the PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it keep on working.

ps3fb: Add virtual screen and panning support: - The vertical virtual screen size is limited by the amount of memory reserved for ps3fb, - The horizontal virtual screen size is limited to the fullscreen width, - Advertise that we support panning, so fbcon will use it if the virtual screen is enabled. Enabling a virtual screen (using `fbset -vyres nnn') can speed up text console scrolling by a factor of 10-15, depending on the video mode. Signed-off-by: -

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:
