2005-09-15[PATCH] vgacon: Fix sanity checking in vgacon_resizeAntonino A. Daplas
Reported by: walt <wa1ter@myrealbox.com> "I routinely switch the console font during bootup to 8x8 so I can get 50 lines per screen. Until 09 Sept, just changing to the small font automatically gave me all 50 lines -- but now I'm only getting 25 lines even with the small font. The bottom half of the screen displays the text that already scrolled off the top." This bug is due to an erroneous check in the recently added hook, vgacon_resize(). It checks the new height against the original number of rows of the console. Because the original number of rows depends on both the scanline and the font height, check it instead against the scanline/fontheight.

2005-09-13[PATCH] fbcon: constify font dataJan Beulich
const-ify the font control structures and data, to make somewhat better guarantees that these are not modified anywhere in the kernel. Specifically for a kernel debugger to share this information from the normal kernel code, such a guarantee seems rather desirable. Signed-off-by: Jan Beulich <jbeulich@novell.com> Cc: "Antonino A.

2005-09-12[PATCH] USB: sisusb[vga] updateThomas Winischhofer
here is a new and extended version of the sisusbvga (previously: sisusb) driver. The patch is against 2.6.13 and updates the driver to version 0.0.8. Additions include complete VGA/EGA text console support and a build-in display mode infrastructure for userland applications that don't know about the graphics internals. Fixes include some BE/LE issues and a get/put_dev bug in the previous version. Other changes include a change of the module name from "sisusb" to "sisusbvga". The previous one was too generic IMHO. Please note that the patch also affects the Makefile in drivers/video/console as the driver requires the VGA 8x16 font in case the text console part is selected. Heavily tested, as usual. Please apply. One thing though: I already prepared for removal of the "mode" field and the changed "name" field in the usb_class_driver structure. This will perhaps need some refinement depending on whether you/Linus merge the respective core changes before or after 2.6.14.

The function bit_putcs() in drivers/video/console/bitblit.c is becoming large. Break it up into its component functions (bit_putcs_unaligned and bit_putcs_aligned).

2005-09-09[PATCH] framebuffer: bit_putcs() optimization for 8x* fontsKnut Petersen
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.

2005-09-09[PATCH] fbcon: Saner 16-color to 4-color conversionAntonino A. Daplas
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.

2005-09-09[PATCH] fbdev: Fix greater than 1 bit monochrome color handlingAntonino A. Daplas
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.

2005-09-09[PATCH] vga text console and stty cols/rowsSamuel Thibault
Some people use 66-cells braille devices for reading the console, and hence would like to reduce the width of the screen by using: stty cols 66 However, the vga text console doesn't behave correctly: the 14 first characters of the second line are put on the right of the first line and so forth. Here is a patch to correct that. It corrects the disp_end and offset registers of the vga board on console resize and console switch. On usual screens, you then correctly get a right and/or bottom blank margin. On some laptop panels, the output is resized so that text actually gets magnified, which can be great for some people (see http://dept-info.labri.fr/~thibault/ls.jpg ).

2005-07-27[PATCH] fbcon: don't repaint the cursor when it is disabled.Michal Januszewski
Currently even when the cursor is disabled (`setterm -cursor off`), it is still repainted as a black rectangle the size of a single char. This can be seen, for example, by chvt'ing to a free tty, disabling the cursor and doing `dd if=3D/dev/urandom of=3D/dev/fb0`. The patch changes this behaviour by avoiding painting anything when the cursor is disabled.

2005-06-21[PATCH] New framebuffer fonts + updated 12x22 font availableJurriaan
Improve the fonts for use with the framebuffer. I've added all the characters marked 'FIXME' in the sun12x22 font and created a 10x18 font (based on the sun12x22 font) and a 7x14 font (based on the vga8x16 font). This patch is non-intrusive, no options are enabled by default so most users won't notice a thing. I am placing my changes under the GPL, however, I've not seen any copyright notices on the sun12x22 font and the vga8x16 font which I derived my new fonts from so I don't know what the copyright status is.

2005-06-21[PATCH] VGA to fbcon fix.James Simmons
Currently when going from vgacon to fbcon the VT screenbuffer are often different sizes. In the case when they are different sizes a new VT screenbuffer is allocated and the contents are copied into the new buffer. Currently the amount copied from VGA text memory to the new screenbuf is the size of the framebuffer console. If the framebuffer console new VT screen buffer is greater than the VGA text memory size then we get some of the VGA BIOS contents as well. This patch will only allow you to copy up to the size of VGA text memory now. The rest is filled with erase characters.

2005-05-01[PATCH] vgacon: set vc_hi_font_mask correctlyBill Nottingham
When allocating a new VC with vgacon_init(), the font is shared across all the VGA consoles. However, the font mask was always set to the default value of zero in visual_init(), even if we were using 512 character fonts at the time. Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the console driver thinks it's already in 512 character mode. This means that to *fix* it, you'd actually have to take the console out of 512 character mode and then set it back. The attached sets vc_hi_font_mask in vgacon_init() for any new consoles opened if the vgacon driver is already in 512 character mode, solving this. This bug goes back to 2.4.18 at least, probably earlier. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
