* [PATCH] fbcon: Break up bit_putcs into its component functionsAntonino A. Daplas2005-09-091-9/+1
| | | | | | | | | | | | 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). Incorporated fb_pad_aligned_buffer() optimization by Roman Zippel.

* [PATCH] fbdev: Add VESA Coordinated Video Timings (CVT) supportAntonino A. Daplas2005-09-091-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fbdev: Fix greater than 1 bit monochrome color handlingAntonino A. Daplas2005-09-091-13/+28
| | | | | | | | | | | 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.

* [PATCH] intelfb/fbdev: Save info->flags in a local variableAntonino A. Daplas2005-08-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reported by: Pavel Kysilka (Bugzilla Bug 5059) The intelfb driver does not keep resolution set with fbset after switching to anot console and back. Steps to reproduce: initial options: tty1,tty2 - 1024x768-60 1) tty1 - fbset after booting (1024x768-60) 2) tty1 - fbset 800x600-100 tty1: 800x600-100 3) swith to tty2, swith to tty1 tty1: 1024x768-60 (the same resolution as default from kernel booting) This bug is caused by intelfb unintentionally destroying info->flags in set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify fbcon of a mode change was cleared causing the above problem. This bug though is not intelfb specific, as other drivers may also be affected. The fix is to save info->flags in a local variable before calling any of the driver hooks. A more definitive fix (for post 2.6.13) is to separate info->flags into one that is set by the driver and another that is set by core fbdev/fbcon.

* [PATCH] fbdev: Replace memcpy with for-loop when preparing bitmapAntonino A. Daplas2005-07-291-2/+4

* [PATCH] fbdev: iomove removalJames Simmons2005-06-211-52/+5
| | | | | | | | | | | | | Since no one is using the inbuf, outbuf of struct fb_pixmap I removed their use in the framebuffer console. The idea is instead move the pixmap functionality below the accelerated functions intead of on top as the way it is now. If there is no objection please apply. This is against Linus latestr GIT tree.

* [PATCH] DocBook: changes and extensions to the kernel documentationPavel Pisa2005-05-011-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have recompiled Linux kernel 2.6.11.5 documentation for me and our university students again. The documentation could be extended for more sources which are equipped by structured comments for recent 2.6 kernels. I have tried to proceed with that task. I have done that more times from 2.6.0 time and it gets boring to do same changes again and again. Linux kernel compiles after changes for i386 and ARM targets. I have added references to some more files into kernel-api book, I have added some section names as well. So please, check that changes do not break something and that categories are not too much skewed. I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved by kernel convention. Most of the other changes are modifications in the comments to make kernel-doc happy, accept some parameters description and do not bail out on errors. Changed <pid> to @pid in the description, moved some #ifdef before comments to correct function to comments bindings, etc. You can see result of the modified documentation build at http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz Some more sources are ready to be included into kernel-doc generated documentation. Sources has been added into kernel-api for now. Some more section names added and probably some more chaos introduced as result of quick cleanup work.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+1371
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!
