2009-05-29atmel_lcdfb: correct fifo size for some productsNicolas Ferre1-8/+2
Remove wrong fifo size definition for some AT91 products. Due to a misunderstanding of some AT91 datasheets, a fifo size of 2048 (words) has been introduced by mistake. In fact, all products (AT91/AT32) are sharing the same fifo size of 512 words.

This patch fixes the LCDC driver to avoid calling the function sh_mobile_lcdc_start_stop(priv, 0) unless the same function has been called before to start the LCDC hardware.

2009-05-21[ARM] 5519/1: amba probe: pass "struct amba_id *" instead of void *Alessandro Rubini1-1/+1
The second argument of the probe method points to the amba_id structure, so it's better passed with the correct type. None of the current in-tree drivers uses the pointer, so they have only been checked for a clean compile. Change suggested by Russell King.

2009-05-07fbdev: fix fillrect for 24bpp modesMichal Januszewski3-39/+48
The software fillrect routines do not work properly when the number of pixels per machine word is not an integer. To see that, run the following command on a fbdev console with a 24bpp video mode, using a non-accelerated driver such as (u)vesafb: reset ; echo -e '\e[41mtest\e[K' The expected result is 'test' displayed on a line with red background. Instead of that, 'test' has a red background, but the rest of the line (rendered using fillrect()) contains a distored colorful pattern. This patch fixes the problem by correctly computing rotation shifts. It has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

2009-05-03vgacon: return the upper half of 512 character fontsStefan Bader1-1/+1
Uwe Geuder noted that he gets random bitmaps on a text console if he tried to type extended characters (like the e acute). For him everything above unicode 0xa0 was corrupted. After some digging there seems to be a little culprit in vgacon since the beginning of ages (well git). The function vgacon_font_get will store the number of characters correctly in font->charcount but then calls to vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters are actually stored to the fontdata. The rest is left untouched. So the next time that saved data is used, the garbled font appears. This happens on every switch between text consoles.

This patch adds support for the new Apple models incorporating an Nvidia chipset. Apple still uses the same protocol as on older models, but the registers moved to a different address. To do this, two sets of functions are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH function. The initial code has been contributed by Hu Gang <hugang@soulinfo.com>. The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook Pro 5. Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing brightness within X doesn't work, if using Nvidia's proprietary graphics driver with no known fix at present. Changing brightness on a text console or using the open-source driver does work. MacBook Pro 5 has a known bug where the initial brightness after bootup is the last recently used brightness (in Mac OSX), while the firmware reports maximum. Impossible to fix.

2009-04-01efifb: dmi set video typeBrian Maly1-1/+4
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.

2009-04-01fb: hide hardware cursor in graphics mode (Mach64)Krzysztof Helt1-1/+2
A hardware cursor is left enabled in the fb_set_par() which is called when a new console is created. This is inconsistent with software cursor's behaviour. Also, this makes a hardware cursor always visible in the Xfbdev (Xorg kdrive) server.

2009-04-01uvesafb: fix selecting mode with the vbemode optionMichal Januszewski1-4/+9
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.

2009-04-01fbdev: remove cyblafb driverKrzysztof Helt3-1710/+7
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).

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.
