Fix a circular locking dependency in the frame buffer console driver pushing down the mutex fb_info->lock. Circular locking dependecies occur calling the blocking fb_notifier_call_chain() with fb_info->lock held. Notifier callbacks can try to acquire mm->mmap_sem, while fb_mmap() acquires the locks in the reverse order mm->mmap_sem => fb_info->lock. Tested-by:

Fix handling of the Cirrus Logic GD5434 chip. Distinguish this chip from the GD5430. It allows detecting memory size for both models correctly. Signed-off-by:

A memory clock (MCLK) is set at various places. Move the setting into one place. Set the MCLK only for Zorro cards as the x86 cards should be initialized by BIOS. Improve handling of the GD5434 (SD64). Kill one annoying debug output "virtual offset: ...". Signed-off-by:

Cirrus' Alpine and Picasso4 chips uses DAC clock doubling to achieve full range of pixclock frequencies. [akpm@linux-foundation.org: fix spelling, use usual comment layout] Signed-off-by:

The 32bpp is supported only on the latest Cirrus Logic chips. Use the 24bpp which is supported at least since Alpine chips (GD543x). Change 32bpp mode setting to 24bpp mode. Change acceleration as well. Signed-off-by:

Various fixes to make Cirrus GD5446 chip work. Another Cirrus chip works with the cirrusfb. The gd5446 seems very similar to Alpine chips. Signed-off-by:

- Fix color expansion for 16bpp and 32bpp modes in the cirrusfb_RectFill(). - Make a function with a common blitter code (cirrusfb_set_blitter). - Add fb_sync function to allow a higher layer synchronize with the blitter. - Kill one redundant blitter reset. Signed-off-by:

- The Laguna GD5465 (AGP) has one register more than non-AGP chips. Recognize the AGP version and write a tile control register only on the AGP version. Tested only on an AGP card. - Bump up RAMDAC frequencies after X11 code. This allow to drive a flat panel resolution 1680x1050 at 16bpp from the 4MB card. - Fix screen start address overflow bits on Laguna cards (CRT1D register). - Fix exit path in the cirrusfb_pci_register() in case of error.

Break cirrusfb_decode_var() function into two parts: cirrusfb_check_pixclock() which can be called from the cirrusfb_check_var() aand merge rest into the cirrusfb_set_par_foo(). This allows rejecting modes with too high pixclock before before any change to hardware state (and a console is messed up). Also, fix RGB field's lengths for 8bpp modes to correct ones so X11 works with fbdev driver with cirrusfb. Kill some redundant function calls or register loads. Signed-off-by:

Fix 8bpp mode by adding handling of the Laguna chipsets to various places and stop trashing a HDR register which probably does not exist on the Laguna. Fix compilation warnings about uninitialized variables also. Finally, all 8bpp, 16bpp and 32bpp modes work on the Laguna chipset. Signed-off-by:

Various improvements to the code: - kill a structure with only one field: multiplexing and use the field directly - move the cirrusfb_ops structure down the file to kill forward declarations - move cirrusfb_init() to kill forward declaration - kill register loads done already in the init_vgachip() - kill assigments done by higher layer in the cirrusfb_pan_display() - do not overwrite line pitch bit in the CL_CRT1D register - kill btype variables if they were used only once or twice - add cpu_relax() in the busy waiting loop The fix to the CL_CRT1D register handling makess the 1024x768 32bpp mode work. Previously, only lower resolution modes have worked with 32bpp. Signed-off-by:

Use the 5-6-5 RGB mode instead of the 5-5-5 mode at 16bpp depth. It fixes colors in the 16bpp modes on Cirrus Laguna chips. Signed-off-by:

A line length is calculated twice: first in the cirrusfb_decode_var() then in the cirrusfb_set_par_foo(). Use the first calculated value. A nice side effect is that 32bpp mode works now. Signed-off-by:

The Laguna chipsets use special registers which are available through the mmio area. The cirrusfb driver does not use memory mapped registers for the PCI cards. Add the memory mapped area for Laguna chipsets and add basic usage of the special Laguna registers after SVGALIB code. This gives readable console at 16bpp on the GD-5465 (Laguna AGP). The 8bpp and 32bpp depths are still broken. Signed-off-by:

Add additional overflow register setting for Laguna chips. Also, simplify some code in the cirrusfb_pan_display() and cirrusfb_blank(). Signed-off-by:

Fix memory detection and clock setting for Cirrus Laguna chipsets (GD5464/GD5465). The changes are done after the Xorg code. The driver still does not display anything on the GD5465 but it switches resolutions correctly at least. Signed-off-by:
