2010-12-14fbdev: Fix fb_find_nearest_mode refresh comparisonAndrew Kephart
Refresh rate nearness is not calculated or reset when nearest resolution changes. This patch resets the refresh rate differential measurement whenever a new nearest resolution is discovered. This fixes two error cases; first, wherein the first mode's refresh rate differential is never calculated and second, when the closest refresh rate from a previous nearest resolution is erroneously preserved.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2008-04-28fbdev: make the best-fit section of fb_find_mode return the closest matching ↵Michal Januszewski
mode Currently, if a perfect match in terms of resolution is not found, fb_find_mode() only looks for a best-fit mode among modes with a higher resolution than the one requested. Thus, if the user requests a resolution higher than the largest supported one, they are dropped to the default mode (usually a low resolution one). Change this behaviour so that all valid video modes are considered when looking for a best-fit mode, while still preferring modes with a higher resolution.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members.

This patch fixes the function so that it looks for the closest mode as far as both resolution and refresh rate are concerned.

2005-09-09[PATCH] fbdev: Add VESA Coordinated Video Timings (CVT) supportAntonino A. Daplas
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>
2005-08-08[PATCH] nvidiafb: Fix initial display corruption on certain laptopsAntonino Daplas
Reported by:Vincent Fortier (Bugzilla Bug 4768) "At boot time the screen appears moved to the mid right portion of the actual video pannel making the end of the line appears at the left edge... It simply looks like moved half way to the right" His particular hardware has a display with an unusual dimension (1920x1200) but unfortunately has no EDID block. None of the entries in the global mode database is correct for this particular display, and it particularly has difficulty scaling up 640x480 (the default startup mode of nvidiafb) to 1920x1200 which causes the above described problem. 1, Add 1920x1200 to the global mode database. 2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the EDID block is absent, no boot mode parameter is specified by the user, and a flatpanel/LCD display is attached.

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!
