nvidiafb: Add boot option to reverse i2c port assignment

2007-10-16T16:43:19Z

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: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nvidiafb: Add proper support for Geforce 7600 chipset

2007-07-17T17:23:11Z

Add proper support for the Geforce 7600 (device id 0x039x). This also sync's nvidiafb with the latest Xorg nv driver. Signed-off-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nvidiafb: adjust flags to take advantage of new scroll method

2007-07-17T17:23:11Z

The SCROLL_MOVE method has been optimized such that it is significantly faster than SCROLL_REDRAW. Adjust flags to indicate that blitting is preferred over rendering. Signed-off-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nvidiafb: VGA state save and restore

2007-05-08T18:15:28Z

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 non-linear mapping of the VGA registers to the MMIO space, this will be done only on X86 platforms where the device is the primary display. An echo 0 > /sys/class/vtconsole/vtcon1/bind will convert the display from graphics to text mode. Signed-off-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nvidiafb: ensure that CRTC registers are accessible

2007-05-08T18:15:28Z

- 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: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: Allow enable/disable of fb backlights, fixing regressions

2007-03-05T08:49:38Z

Enabling the backlight by default appears to cause problems for many users. This patch disables backlight controls unless explicitly enabled by users via a module parameter. Since PMAC users are known to work, default to enabled in that case. Signed-off-by: Richard Purdie

backlight: Rework backlight/fb interaction simplifying, lots

2007-02-20T08:38:46Z

fb_info->bl_mutex is badly thought out and the backlight class doesn't need it if the framebuffer/backlight register/unregister order is consistent, particularly after the backlight locking fixes. Fix the drivers to use the order: backlight_device_register() register_framebuffer() unregister_framebuffer() backlight_device_unregister() and turn bl_mutex into a lock for the bl_curve data only.
