* fb: fix fast-path blt detectionUlrich Sibiller2018-12-191-27/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of this commit: commit a2880699e8f1f576e1a48ebf25e8982463323f84 Author: Keith Packard <keithp@keithp.com> Date: Tue Mar 25 08:21:16 2014 -0700 fb: fix fast-path blt detection The width parameter is used to disable the blit fast-path (memcpy) when source and destination rows overlap in memory. This check was added in [0]. Unfortunately, the calculation to determine if source and destination lines overlapped was incorrect: (1) it converts width from pixels to bytes, but width is actually in bits, not pixels. (2) it adds this byte offset to dst/srcLine, which implicitly converts the offset from bytes to sizeof(FbBits). Fix both of these by converting addresses to byte pointers and width to bytes and doing comparisons on the resulting byte address. For example: A 32-bpp 1366 pixel-wide row will have width = 1366 * 32 = 43712 bits bpp = 32 (bpp >> 3) = 4 width * (bpp >> 3) = 174848 FbBits (FbBits *)width => 699392 bytes So, "careful" was true if the destination line was within 699392 bytes, instead of just within its 1366 * 4 = 5464 byte row. This bug causes us to take the slow path for large non-overlapping rows that are "close" in memory. As a data point, XGetImage(1366x768) on my ARM chromebook was taking ~140 ms, but with this fixed, it now takes about 60 ms.

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.) v3: Convert to byte units This first checks to make sure the blt is byte aligned, converts all of the data to byte units and then compares for byte address range overlap between source and dest.

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.

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.

* 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.
