This set of two patches add support for the framebuffer of the Samsung S3C2410 ARM SoC. This driver was started about one year ago and is now used on iPAQ h1930/h1940, Acer n30 and probably other s3c2410-based machines I'm not aware of. I've also heard yesterday that it's working also on iPAQ rx3715/rx3115 (s3c2440-based machines). Signed-Off-By:

Add ddc/i2c support for i810fb. This will allow the driver to get display information, especially for monitors with fickle timings. The i2c support depends on CONFIG_FB_I810_GTF. Changed __init* to __devinit* Signed-off-by:

To solve touchscreen interference problems devices like the Sharp Zaurus SL-C3000 need to know the length of the horitzontal sync pulses. This patch adds a hook to pxafb so the touchscreen driver can function correctly. Signed-Off-By:

The Coordinated Video Timings (CVT) is the latest standard approved by VESA concerning video timings generation. It addresses the limitation of GTF which is designed mainly for CRT displays. CRT's have a high blanking requirement (as much as 25% of the horizontal frame length) which artificially increases the pixelclock. Digital displays, on the other hand, needs to conserve the pixelclock as much as possible. The GTF also does not take into account the different aspect ratios in its calculation. The new function added is fb_find_mode_cvt(). It is called by fb_find_mode() if it recognizes a mode option string formatted for CVT. The format is: <xres>x<yres>[M][R][-<bpp>][<at-sign><refresh>][i][m] The 'M' tells the function to calculate using CVT. On it's own, it will compute a timing for CRT displays at 60Hz. If the 'R' is specified, 'reduced blanking' computation will be used, best for flatpanels. The 'i' and the 'm' is for 'interlaced mode' and 'with margins' respectively. To determine if CVT was used, check for dmesg for something like this: CVT Mode - <pix>M<n>[-R], ie: .480M3-R (800x600 reduced blanking) where: pix - product of xres and yres, in MB M - is a CVT mode n - the aspect ratio (3 - 4:3; 4 - 5:4; 9 - 16:9, 15:9; A - 16:10) -R - reduced blanking Signed-off-by: -

This patch changes radeon to request only resources 0 and 2 instead of all 3. This works around problems with some setups where BAR 1 (IO BAR) has not been assigned by the firmware since it's not used on the machine and the kernel fails to assign something to it due to the card being between a P2P bridge that was configured without an IO range at all. This typically fixes radeonfb on some Apple Xserve G5 machines Signed-off-by:

This trivial patch gives a performance boost to the framebuffer console Constructing the bitmaps that are given to the bitblit functions of the framebuffer drivers is time consuming. Here we avoide a call to the slow fb_pad_aligned_buffer(). The patch replaces that call with a simple but much more efficient bytewise copy. The kernel spends a significant time at this place if you use 8x* fonts. Every pixel displayed on your screen is prepared here. Some benchmark results: Displaying a file of 2000 lines with 160 characters each takes 889 ms system time using cyblafb on my system (I´m using a 1280x1024 video mode, resulting in a 160x64 character console) Displaying the same file with the enclosed patch applied to 2.6.13 only takes 760 ms system time, saving 129 ms or 14.5%. Font widths other than 8 are not affected. The advantage and correctness of this patch should be obvious. Signed-off-by:

This is a framebuffer driver for the Cyberblade/i1 graphics core. Currently tridenfb claims to support the cyberblade/i1 graphics core. This is of very limited truth. Even vesafb is faster and provides more working modes and a much better quality of the video signal. There is a great number of bugs in tridentfb ... but most often it is impossible to decide if these bugs are real bugs or if fixing them for the cyberblade/i1 core would break support for one of the other supported chips. Tridentfb seems to be unmaintained,and documentation for most of the supported chips is not available. So "fixing" cyberblade/i1 support inside of tridentfb was not an option, it would have caused numerous if(CYBERBLADEi1) else ... cases and would have rendered the code to be almost unmaintainable. A first version of this driver was published on 2005-07-31. A fix for a bug reported by Jochen Hein was integrated as well as some changes requested by Antonino A. Daplas. A message has been added to tridentfb to inform current users of tridentfb to switch to cyblafb if the cyberblade/i1 graphics core is detected. This patch is one logical change, but because of the included documentation it is bigger than 70kb. Therefore it is not sent to lkml and linux-fbdev-devel, Signed-off-by:

This lifts sisfb from version 1.7.17 to version 1.8.9. Changes include: - Added support for XGI V3XT, V5, V8, Z7 chipsets, including POSTing of all of these chipsets. - Added support for latest SiS chipsets (761). - Added support for SiS76x memory "hybrid" mode. - Added support for new LCD resolutions (eg 1280x854, 856x480). - Fixed support for 320x240 STN panels (for embedded devices). - Fixed many HDTV modes (525p, 750p, 1080i). - Fixed PCI config register reading/writing to use proper kernel functions for this purpose. - Fixed PCI ROM handling to use the kernel's proper functions. - Removed lots of "typedef"s. - Removed lots of code which was for X.org/XFree86 only. - Fixed coding style in many places. - Removed lots of 2.4 cruft. - Reduced stack size by unifying two previously separate structs into one. - Added new hooks for memory allocation (for DRM). Now the driver can truly handle multiple cards, including memory management. - Fixed numerous minor bugs. Signed-off-by:

This updates the matroxfb code so that it can find the PInS data embedded in the BIOS on PowerPC cards. The process for finding the data is different on OpenFirmware cards than on x86 cards, and the code for doing so was missing. After patching, building, installing, and booting a kernel, you should grep for "PInS" in /var/log/messages. You should see two messages in the log: PInS data found at offset XXXXX PInS memtype = X On the GXT135p card I get "31168" and "5". The first value is irrelevant, but it's presence lets me know that the PInS data was actually found. On a GXT130p, the second value should be 3. Since I don't have access to that hardware, if someone can verify that, I will submit a follow-on patch that rips out all the memtype parameter stuff. Signed-off-by:

On a vc resize, the contents of the old screen buffer are transferred to the new screenbuffer. If the new screenbuffer is smaller than the old one, only the contents from the bottom are copied to new. If the contents of the old buffer are located at the top, then the contents will not be copied to the new buffer resulting in a blank screen. This bug will happen only if the vc in question is not in the foreground. Doing an fbset -a or con2fbmap will trigger this bug. To fix this problem, base the start of the copy from the location of the current cursor. If the cursor is near the top of the buffer, copy the contents at the top, and if the cursor is near the bottom of the buffer, then copy the contents at the bottom. In the unlikely case where the new row size is greater than 2x smaller than the old one, and the cursor is in the middle, copy 1/2 screenful from the top and bottom of the cursor position.

Currently, the default linux 16-colors are converted to 4-colors by simply dividing the values by 4. However, this is not necessarily correct since the first 4 colors are converted to black, rendering them invisible. So, for black, no conversion; for light colors, convert to gray, for normal text color, no conversion, and for bright colors, convert to intense white. Signed-off-by:

Currently, fbcon assumes that the visual FB_VISUAL_MONO* is always 1 bit. According to Geert, there are old hardware where it's possible to have monochrome at 8-bit, but has only 2 colors, black - 0x00 and white - 0xff. Fix color handlers (fb_get_color_depth, and get_color) for this special case. Signed-off-by:

For the i386, code is already present in video.S that gets the EDID from the video BIOS. Make this visible so drivers can also use this data as fallback when i2c does not work.

LANL reported some issues with random crashes during mount of legacy protocol servers (9P2000 versus 9P2000.u) -- crash was always happening in readlink (which should never happen in legacy mode).
