* fb: Fix memcpy abuseUlrich Sibiller2018-12-191-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes ArcticaProject/nx-libs#750 Backport of this commit: commit e32cc0b4c85c78cd8743a6e1680dcc79054b57ce Author: Adam Jackson <ajax@redhat.com> Date: Thu Apr 21 16:37:11 2011 -0400 fb: Fix memcpy abuse The memcpy fast path implicitly assumes that the copy walks left-to-right. That's not something memcpy guarantees, and newer glibc on some processors will indeed break that assumption. Since we walk a line at a time, check the source and destination against the width of the blit to determine whether we can be sloppy enough to allow memcpy. (Having done this, we can remove the check for !reverse as well.) On an Intel Core i7-2630QM with an NVIDIA GeForce GTX 460M running in NoAccel, the broken code and various fixes for -copywinwin{10,100,500} gives (edited to fit in 80 columns): 1: Disable the fastpath entirely 2: Replace memcpy with memmove 3: This fix 4: The code before this fix 1 2 3 4 Operation ------ --------------- --------------- --------------- ------------ 258000 269000 ( 1.04) 544000 ( 2.11) 552000 ( 2.14) Copy 10x10 21300 23000 ( 1.08) 43700 ( 2.05) 47100 ( 2.21) Copy 100x100 960 962 ( 1.00) 1990 ( 2.09) 1990 ( 2.07) Copy 500x500 So it's a modest performance hit, but correctness demands it, and it's probably worth keeping the 2x speedup from having the fast path in the first place.

* Move each screen's root-window pointer into ScreenRec.Mike Gabriel2016-06-212-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Backported from X.org: commit e7fae9ecc42ab5e73b89117722dbf4117d928f9a Author: Jamey Sharp <jamey@minilop.net> Date: Sat May 22 00:26:28 2010 -0700 Move each screen's root-window pointer into ScreenRec. Many references to the WindowTable array already had the corresponding screen pointer handy, which meant they usually looked like "WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of keeping this information in a parallel array simplifies those expressions, and eliminates a MAXSCREENS-sized array. Since dix uses this data, a screen private entry isn't appropriate. xf86-video-dummy currently uses WindowTable, so it needs to be updated to reflect this change.

* Rename region macros to eliminate screen argumentMike Gabriel2016-05-0223-169/+169
| | | | | | | | | | | | | | | | | | | | | This is a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole nx-X11/programs/Xserver tree: $ cd nx-X11/programs/Xserver && ( git ls-files | grep -v '^fix-' | xargs ./fix-region; ) And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. v1: Keith Packard <keithp@keithp.com> (X.Org xserver commit: 2dc138922b7588515d5f2447e4b9dcdc0bef15e0) v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (apply fix-region script to nx-libs)
* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-283-5/+5
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
