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 Airlie1-1/+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.

2012-03-21Introduce a consistent coding styleKeith Packard1-125/+98
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>

This reverts commit 1564c82417d201de5b9a5ec5e7aa4ef14c45fbad. The drivers used the top bits of the usage_hint to store driver private flags (intel, radeon, nouveau).

2008-12-03Rework symbol visibility for easier maintenancePaulo Cesar Pereira de Andrade1-17/+17
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).

* 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: Improve the algorithm used for tracking offscreen pixmap use.Fredrik Höglund1-1/+1
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.

2007-09-25EXA: Added pitch limitations.Tilman Sauerbeck1-1/+32
Drivers can now specify the max pitches that the accelerator supports.
2007-05-22EXA: Export ExaOffscreenMarkUsed.Michel Dänzer1-0/+3
Can be used to inform EXA that an offscreen area is used outside of EXA.
2007-05-06Fix documentation for Copy hook -- it can copy memory to the scanoutJesse Barnes1-1/+1
buffer too.
2007-04-04Add an EXA driver callback to determine whether a pixmap isThomas Hellstrom1-1/+18
"offscreen" in exa terms, which means accessible to the GPU. Bump exa minor. The change is backwards-compatible.
2007-01-24Bug #7639: Only swap out pixmaps (rather than everything) on VT switch in EXA.Eric Anholt1-3/+3
This is a new behavior for version 2.1 of EXA, and only takes effect if the driver has requested that. Otherwise, the previous behavior remains the same.
2006-12-28Export exaMove{In,Out}Pixmap().Eric Anholt1-0/+6
2006-06-26Move EXA_PM_IS_SOLID() to the public API, since drivers will want it frequently.Eric Anholt1-0/+9
2006-03-15Add more doxygen documentation, including notes on WaitMarker() andEric Anholt1-0/+9
MarkSync() that I noticed were needed while reading the VIA driver.
2006-03-12Improve doxygen formatting, and attempt to clarify the 1:1 ratio ofEric Anholt1-81/+85
successful PrepareCopy()s to DoneCopy()s.
2006-03-10Document the restriction on PrepareAccess() failure, from discussion withEric Anholt1-5/+8
benh.
2006-03-09Do a first pass of doxygen documentation of EXA. This removes theEric Anholt1-45/+493
corresponding pieces of exa-driver.txt, which were becoming stale. Hopefully the documentation will stay much more up-to-date this way. Many thanks to jbarnes for writing exa-driver.txt which was used a lot in writing this documentation.
2006-03-09Rearrange EXA driver structures so that there's a hope of maintaining ABIEric Anholt1-24/+17
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.
2006-03-01Add accelerated two directional blt support to EXAJesse Barnes1-1/+1
2006-02-28fix exaInitCard by making it a real functionJesse Barnes1-12/+5
2006-02-16Move EXA implementation up to the top level and remove its XFree86Eric Anholt1-0/+3
dependencies. It was nearly abstract enough already to be used by multiple DDXes. This will be useful for EXA development through providing a fake acceleration implementation within Xephyr, so that testing can be done on new EXA code without worrying about buggy drivers.
2005-10-11Fix a couple of bugs in the offscreen allocator. One mostly harmless wasBenjamin Herrenschmidt1-3/+3
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().
2005-09-18Break EXA ABI while we still can. Add coordinates to the UploadToScreenEric Anholt1-0/+4
hook so we can upload a subset of a pixmap, and convert the current drivers to respect that. Use this support to directly UploadToScreen in exaGlyphs, providing a 47.4% +/-2.4% decrease in wall time for ls -lR programs/Xserver in an antialiased gnome-terminal on an M6 (n=3, caches hot). I would have bumped major version, only I can't tell what the EXA_VERSION_* is supposed to be doing as opposed to the module version.
