If the vbemode option is used, uvesafb calls fb_get_mode() without first setting the resolution in info->var. This results in a division by zero in fb_get_mode(), as evidenced e.g. in [1]. Fix this by ensuring the info->var structure is populated before fb_get_mode() is called. [1] http://bugzilla.kernel.org/show_bug.cgi?id=11661#c37Signed-off-by:

A tridentfb driver has all the functionality of the cyblafb driver without the bugs of the latter. Changes to the tridentfb driver: - FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter for scrolling which is faster than color expansion on Cyberblade chipsets. The blitter is slower on a discrete Blade3D core. Use the blitter for scrolling in the tridentfb only for integrated Blade3D cores. Now, scrolling speed is about equal for the tridentfb and the cyblafb. - a copyright notice addition is done on request of Jani Monoses (the first author of the tridentfb). Tested on AGP Blade3D card and PCChips M787CLR motherboard: VIA C3 cpu + VT8601 north bridge (aka Cyberblade/i1). Signed-off-by:

Add support for the newer Samsung devices, such as found in the S3C2443, S3C6400 or S3C6410 series SoC. It currently does not support all the alpha- or chroma-key options but it will support more exporting more than one framebuffer ready for adding overlay and blending functions. Signed-off-by:

The s1d13xxx chip provides two values of identification value: the Production id (e.g 13506/13505/13806..) and a revision number 0,1,2,3). Together these can help us to differentiate between similiar setups. This patch adds the proper way of grabbing both those values and save them for future reference (in order to decide what functions a card supports, e.g acceleration). We also move away from the concept of all s1d13xxx = s1d13806 when we really support alot more.

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:

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:

- 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.
