2009-11-12savagefb: fix blanking mode on CRT displayKrzysztof Helt
Fix wrong bit mask for blanking register. Due to the error a CRT monitor blanks off due to wrong frequency (out of range) instead of PM signal (vertical and horizontal frequencies cut off). Just compare the mask with bits set in the switch(blank) clause below the changed line.

2009-11-12fb: remove fb_save_state() and fb_restore_state operationsKrzysztof Helt
Remove fb_save_state() and fb_restore_state operations from frame buffer layer. They are used only in two drivers: 1. savagefb - and cause bug #11248 2. uvesafb Usage of these operations is misunderstood in both drivers so kill these operations, fix the bug #11248 and avoid confusion in the future. Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release). This defeats the purpose of these operations.

2007-05-08savagefb: VGA state save and restoreAntonino A. Daplas
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.

2006-06-26[PATCH] savagefb: Add state save and_restore hooksAntonino A. Daplas
Reported by: Rich (Bugzilla Bug 6417) "if savage driver is used in x.org together with savagefb, it results in seriously garbled and distorted screen - coupled with severe slowdowns." This bug is the result of Xorg unable to handle savagefb altering the hardware which results in X failing to start properly and/or failed console switching. Add savagefb_state_save and savagefb_state_restore. These hooks will only save and restore the extended VGA registers. Standard VGA registers will be left alone. This is enough to make savagefb play nicely with the latest Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts may appear before X loads and during console switches). (Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I have to unblank the screen before Xorg loads. So I doubt if the transient screen artifacts will be completely invisible but hopefully it will only be for a shorter duration (not much).)

2005-11-09[PATCH] savagefb: X-panning fixesAntonino A. Daplas
The driver unconditionally sets xpanstep to 2. However, a value of 4 empirically works better at bpp = 8, and 2 for 16 and 32. This buglet was exposed by the rotation code. Second fix is the unconditional call to update_start() without verifying if the offsets are correct. Remove this call, it's not necessary and secondly, it causes a crash with invalid values.

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
