2014-01-12Replace 'pointer' type with 'void *'Keith Packard1-1/+1
This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer' is used throughout the X server for other things, and having duplicate names generates compiler warnings. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>
2012-06-05api: rework the X server driver API to avoid global arrays.Dave Airlie1-3/+1
This is a squash merge containing all the API changes, as well as the video ABI bump. Its been squashed to make bisection easier. Full patch log below: commit b202738bbf0c5a1c1172767119c2c71f1e7f8070 Author: Aaron Plattner <aplattner@nvidia.com> Date: Mon May 14 15:16:11 2012 -0700 xfree86: Bump video ABI to 13.0 The ABI was broken by changes to convert from screen index numbers to ScreenPtr / ScrnInfoPtr in various structures and function signatures.

Mostly scrnIndex is used for logging, but some drivers use it to lookup xf86Screens, so let them stash a pScrn instead. Removing the scrnIndex is a bit more involved and I'm not sure its worth the effort. Doing i2c in the X server is legacy code as far as I'm concerned.

This is strictly the application of the script 'x-indent-all.sh' from util/modular. Compared to the patch that Daniel posted in January, I've added a few indent flags: -bap -psl -T PrivatePtr -T pmWait -T _XFUNCPROTOBEGIN -T _XFUNCPROTOEND -T _X_EXPORT The typedefs were needed to make the output of sdksyms.sh match the previous output, otherwise, the code is formatted badly enough that sdksyms.sh generates incorrect output. The generated code was compared with the previous version and found to be essentially identical -- "assert" line numbers and BUILD_TIME were the only differences found. The comparison was done with this script: dir1=$1 dir2=$2 for dir in $dir1 $dir2; do (cd $dir && find . -name '*.o' | while read file; do dir=`dirname $file` base=`basename $file .o` dump=$dir/$base.dump objdump -d $file > $dump done) done find $dir1 -name '*.dump' | while read dump; do otherdump=`echo $dump | sed "s;$dir1;$dir2;"` diff -u $dump $otherdump done Signed-off-by: Keith Packard <keithp@keithp.com> Acked-by: Daniel Stone <daniel@fooishbar.org> Acked-by: Alan Coopersmith <alan.coopersmith@oracle.com>

2008-12-03Rework symbol visibility for easier maintenancePaulo Cesar Pereira de Andrade1-4/+4
Save in a few special cases, _X_EXPORT should not be used in C source files. Instead, it should be used in headers, and the proper C source include that header. Some special cases are symbols that need to be shared between modules, but not expected to be used by external drivers, and symbols that are accessible via LoaderSymbol/dlopen. This patch also adds conditionally some new sdk header files, depending on extensions enabled. These files were added to match pattern for other extensions/modules, that is, have the headers "deciding" symbol visibility in the sdk. These headers are: o Xext/panoramiXsrv.h, Xext/panoramiX.h o fbpict.h (unconditionally) o vidmodeproc.h o mioverlay.h (unconditionally, used only by xaa) o xfixes.h (unconditionally, symbols required by dri2) LoaderSymbol and similar functions now don't have different prototypes, in loaderProcs.h and xf86Module.h, so that both headers can be included, without the need of defining IN_LOADER. xf86NewInputDevice() device prototype readded to xf86Xinput.h, but not exported (and with a comment about it).
2008-11-28Make visible symbols required by xorg modules.Paulo Cesar Pereira de Andrade1-4/+4
This patch exports all symbols required by the compilable (in a x86 linux computer) xorg/driver/* modules. Still missing symbols worth mentioning are: sunleo miFindMaxBand no longer available intel (uxa/uxa-accel.c) fbShmPutImage no longer available (and should have been static) mga MGAGetClientPointer (should come from matrox's libhal) This is not a definitive "visibility" patch, as all it does is to export missing symbols, but the modules that current don't compile, may require more symbols once fixed, and third party drivers should also require more symbols exported. A "definitive" patch should export symbols defined in the sdk.
2008-04-21EXA: Offscreen memory eviction improvements.Michel Dänzer1-15/+34
* Make sure available areas are considered to have no eviction cost. This seems to help for https://bugs.freedesktop.org/show_bug.cgi?id=15513 but I'm afraid that may just be coincidence. * Only calculate eviction cost of each area once for each eviction pass. Safeguard against potential (though unlikely) division by zero. * Cosmetic enhancements: Name eviction cost related variables 'cost' instead of 'score' to emphasize that smaller values are better, update Doxygen file comment to the way eviction works now.
2008-03-31EXA: Optimize the eviction scanning loop in exaOffscreenAlloc.Fredrik Höglund1-48/+58
Reduce the cost of the inner loop, by keeping a set of pointers to the first and the last areas in the series, subtracting the cost of the first area from the score, and adding the cost of the last area while walking the list. This commit also moves the scanning loop from exaOffscreenAlloc into a separate function. Idea by Michel Dänzer.
2008-03-31EXA: Improve the algorithm used for tracking offscreen pixmap use.Fredrik Höglund1-22/+14
Replace the current score keeping algorithm with a rolling counter that's incremented in ExaOffscreenMarkUsed, with the previous value being stored in the area. exaOffscreenAlloc uses the difference between the counter value and the value in the area when deciding which area to evict. It now also takes the size of the areas into account, and favors evicting smaller areas. The credit for these ideas goes to Michel Dänzer.

when extending the driver interface. The card and accel structures are merged into the ExaDriverRec, which is to be allocated using exaDriverAlloc(). The driver structure also grows exa_major and exa_minor, which drivers fill in and have checked by EXA (double-checking that the driver really did check that the EXA version was correct). Removes exaInitCard(), which is replaced by the driver filling in the rec by hand, and the exaGetVersion() and related EXA_*VERSION which are replaced by always using the XFree86 loadable module versioning.

2005-10-11Fix a couple of bugs in the offscreen allocator. One mostly harmless wasBenjamin Herrenschmidt1-16/+18
causing our search loop for evictable blocks to possibly skip a good candiate, and another was the allocator would occasionally use area->offset as if it was the base of the pixmap, while for a pixmap that is not in available state, it is not. This caused some funny miscalculation leading to overlapping pixmaps and accesses beyond the end of the framebuffer. To make things cleared, I renamed save_offset to base_offset, made sure it's the one used everywhere in the allocator, and only align "offset" for the client at the end of exaOffscreenAlloc().

2005-09-21- Change migration-in rule slightly: previously, if your score was lessEric Anholt1-2/+3
than the max, it was bumped, and then if you were above the threshhold you got moved in. Instead, do the above-threshhold check separate from score starting out less than max. While this will likely make thrashing cases worse, I hope it will fix some issues with long term performance (think of an xcompmgr with a backbuffer it's doing only accelerated operations to. If some new pixmap comes in and bumps it out, even once, it will never get a chance to re-migrate because its score will be maxed). Change migration-out to be the same way for symmetry, though it shouldn't ever affect anything. - Fix a lot of debugging output, both in terms of printing quality, and completeness. The fallback debugging covers a lot more now, pointing out new areas for improvement. Debugging toggles are now centralized in exaPriv.h.
2005-08-24Fix a bug where NULL could be dereferenced during the pixmap kick-outEric Anholt1-3/+3
process by referencing the correct offscreen area. Also drive-by the comments related to these for clarity.
2005-08-14- Fix the exa pixmap offset/pitch alignment to deal with non-POT alignmentEric Anholt1-1/+2
requirements. MGA, notably, uses a multiple of 3 in some cases. - Rename the pixmap offset/pitch alignment fields to more clearly state their meaning.
