If the current framebuffer console is rotated (rotate != 0), doing an "fbset -a" will corrupt the current console. Fix by updating the current console only after all non-visible consoles have been updated. Signed-off-by:

Instead of directly linking vgastate.o by individual drivers, create a Kconfig option VGASTATE which can be 'SELECT'ed by individual drivers instead. Signed-off-by:

Antonino A. Daplas authored
Allow the saving and restoration of VGA text mode. The state is saved on the first open and restored on the last close. Because of the VGA registers are linearly mapped to the MMIO space, MMIO access is used which is not limited to X86 platforms nor to the primary display device. An echo 0 > /sys/class/vtconsole/vtcon1/bind will convert the display from graphics to text mode. Signed-off-by:

Use Read/WriteCrtc() to access CRTC registers in nv_i2c.c. These are safer because it uses the correct CRTC base (0x3bx or 0x3dx). Signed-off-by:

- Ensure that CRTC registers are accessible by unlocking them on set_par(), otherwise i2c reading will fail. - The function nvidia_vga_protect(), does not protect the VGA registers, but turns off the screen. Rename it to nvidia_screen_off(). Signed-off-by:

Various cleanups to rivafb/nvidiafb's I2C code: * Drop useless par->bus. * Refactor I2C bus deletion code. * Drop useless variable initialization. * Remove unneeded include of <linux/i2c-id.h>. * Simplify +1/-1. * Add __devinit tags where possible. [adaplas] The varible initialization are not useless. However, rivafb must check if i2c bus are created properly before reading the EDID block. Signed-off-by:

It was always intended for the logo to be drawn only if both fbcon and the driver that is mapped to it are both compiled statically. Currently, if fbcon is loaded prior to the driver, the logo is not shown. Reverse the order, and the code may attempt to draw the logo which is __initdata. By accident, this bug is rarely seen because this method of loading the modules is not common and secondly, a code in fb_prepare_logo() that checks the height of the logo (now a random value) rarely succeeds. Fix by drawing the logo only if both fbcon and the driver are statically compiled. Signed-off-by:

Create a variable, default_utf8, that defines the system-wide default UTF-8 setting. This variable can be altered via sysfs. If the variable is properly set, this should mimimize breakage of UTF-8 encoded consoles when doing a reset or echo -e '\033c' and of newly opened/allocated consoles. This is based from patches by Jan Engelhardt and Paul LeoNerd Evans. Signed-off-by:

When the cursor and echo are disabled on the current console, pressing a key will cause a black rectangle to be painted in the cursor's position. Fix this by not touching the framebuffer in fbcon_cursor() when the cursor is off. Signed-off-by:

After I added some debugging printks I've found that code became a bit confused because it believed that primary monitor is 1920x540, but later it found in CRTC0's registers that panel size is 1920x1200 (Windows also agree that 1920x1200 is primary monitor, and 1920x1080i secondary one). When I applied attached patch then my monitor became as happy as it was before I connected HDMI cable to secondary output. Signed-off-by:

This is support for the TC variations of the TGA boards (properly known as SFB+ or Smart Frame Buffer Plus boards). The 8-plane SFB+ board uses the Bt459 RAMDAC (unlike its PCI TGA counterpart, which uses the Bt485), so bits have been added to support this chip as well. Signed-off-by:

There are cases when we do not want to wait on the delay for automatically updating the "real" framebuffer, this implements a simple ->fsync() hook for explicitly flushing the deferred I/O work. The ->page_mkwrite() handler will rearm the work queue normally. (akpm: nuke unneeded ifdefs, forward-delcare struct dentry) Signed-off-by:

This implements deferred IO support in fbdev. Deferred IO is a way to delay and repurpose IO. This implementation is done using mm's page_mkwrite and page_mkclean hooks in order to detect, delay and then rewrite IO. This functionality is used by hecubafb. [adaplas] This is useful for graphics hardware with no directly addressable/mappable framebuffer. Implementing this will allow the "framebuffer" to be accesible from user space via mmap().

If the option vga=<VESA graphics mode> is added to the boot parameter, it will activate graphics mode, but without any framebuffer support, the user is left with an unusable display. Change the behavior such that the user is instead prompted for another mode (ala vga=ask). NOTE: People can always use vbetool to set a graphics mode if this is really desired, but the number of people doing this approaches zero. Signed-off-by:
