2008-10-16fbmon: fix EDID parser to detect interlace modesJon Dufresne
The current EDID parser in the linux kernel ignores interlace modes. The patch looks for the edid interlace flag and adjusts the vertical resolution if it is found.

2008-07-24fbdev: width and height are unsignedVille Syrjala
The width and height members of fb_var_screeninfo are __u32. The code initializes them to -1 which seems wrong, and 0 seems like an equally good default value.

2007-10-16fbdev: fb_create_modedb() non-static `int first = 1;'Geert Uytterhoeven
Looking at the code flow, `int first' in fb_create_modedb() should be static. [adaplas] Better for 'int first' to be moved outside the loop.

2007-05-08fbdev: add Ultrasharp UXGA to broken monitor databaseAntonino A. Daplas
This particular monitor does not have a limits block and has only one set of monitor timings. Fix by adding a limits block to the EDID and extend the horizontal sync frequency range to 30 kHz and 75 Khz.

2006-07-10[PATCH] vt: Remove VT-specific declarations and definitions from tty.hJon Smirl
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h.

2006-06-26[PATCH] fbdev: More accurate sync range extrapolationAntonino A. Daplas
The EDID block should specify the display's operating limits (vertical and horizontal sync ranges, and maximum dot clock). If not given by the EDID block, the ranges are extrapolated from the modelist. However, the computation used is only a rough approximation, and the resulting values may not reflect the actual capability of the display. This problem is frequently encountered when the EDID block has a single entry, the single mode entry will fail validation. To prevent this, calculate the values based on the same method used in fb_validate_mode().

2005-09-09[PATCH] fbdev: Resurrect hooks to get EDID from firmwareAntonino A. Daplas
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. To ensure that the EDID block is returned for the primary graphics adapter only, by check if the IORESOURCE_ROM_SHADOW flag is set.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
