* efifb: dmi set video typeBrian Maly2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current logic for dmi matching in efifb does not allow efifb to load on all hardware that we can dmi match for. For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a Apple (MacBook) and EFI framebuffer driver will not load (you will have no video). This specific hardware is efi v1.10, so we have UGA and not GOP. Without special bootloader magic (i.e. extra elilo patches for UGA graphics detection) no screen info will be passed to the kernel and as a result efifb will not load. This patch allows the dmi match to happen by moving it to earlier in efifb_init, and sets the video type (in set_system) so that efifb can load when we have a valid dmi match and already know the specifics of the hardware. Without this patch the efifb driver will fail to load in the event screen info is not found and passed in by the bootloader, being that we will never get to look for a dmi match. A primary reason for matching with dmi is because not all bootloaders detect the video info properly. The solution is that in the event of a dmi match, we should set screen_info.orig_video_isVGA. Most bootloaders fail to set screen info on Apple hardware, and this is a big problem for people who use Apple hardware. Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the issue, the dmi match now works, EFI framebuffer now loads and video works.

* tridentfb: delete acceleration Kconfig optionKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | Remove Kconfig option for tridentfb acceleration. The acceleration can be switched off with modules "noaccel" parameter. The acceleration for Trident chips was fixed in the 2.6.27 kernel. Also, add CyberXXX and CyberBlade names to Kconfig option's name. It should make easier to find the tridentfb choice for cyblafb driver's users. The cyblafb driver has been replaced by the tridentfb driver.

* uvesafb: fix selecting mode with the vbemode optionMichal Januszewski2009-04-01
| | | | | | | | | | | | | | 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.

* fbdev: remove cyblafb driverKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* fbdev: update s1d13xxxfb to differ between revisions and production idsKristoffer Ericson2009-04-01
| | | | | | | | | | | | | | | | | | | | 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.

* cirrusfb: various Laguna fixesKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | | | | - 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.

* cirrusfb: check_var improvementsKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | | | 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.

* cirrusfb: Laguna chipset 8bpp fixKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | 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.

* cirrusfb: various improvementsKrzysztof Helt2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Krzysztof Helt <krzysztof.h1@poczta.fm> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
