* mesa: Restore 78-column wrapping of license text in C-style comments.Kenneth Graunke2013-04-231-3/+4
| | | | | | | | | | | | | | The previous commit introduced extra words, breaking the formatting. This text transformation was done automatically via the following shell command: $ git grep 'THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY' | sed 's/:.*$//' | xargs -I {} sh -c 'vim -e -s {} < vimscript where 'vimscript' is a file containing: /THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY/;/\*\// !fmt -w 78 -p ' * ' :wq Reviewed-by: Brian Paul <[email protected]>
* mesa: Add "OR COPYRIGHT HOLDERS" to license text disclaiming liability.Kenneth Graunke2013-04-231-1/+1
| | | | | | | | | | | | | | | This brings the license text in line with the MIT License as published on the Open Source Initiative website: http://opensource.org/licenses/mit-license.php Generated automatically be the following shell command: $ git grep 'THE AUTHORS BE LIABLE' | sed 's/:.*$//g' | xargs -I '{}' \ sed -i 's/THE AUTHORS/THE AUTHORS OR COPYRIGHT HOLDERS/' {} This introduces some wrapping issues, to be fixed in the next commit.

* mesa: Change "BRIAN PAUL" to "THE AUTHORS" in license text.Kenneth Graunke2013-04-231-1/+1
| | | | | | | | | | | | | | | | Generated automatically be the following shell command: $ git grep 'BRIAN PAUL BE LIABLE' | sed 's/:.*$//g' | xargs -I '{}' \ sed -i 's/BRIAN PAUL/THE AUTHORS/' {} The intention here is to protect all authors, not just Brian Paul. I believe that was already the sensible interpretation, but spelling it out is probably better. More practically, it also prevents people from accidentally copy & pasting the license into a new file which says Brian is not liable when he isn't even one of the authors.

* mesa: NULL check the pointer before trying to dereference itIan Romanick2013-04-121-2/+2
| | | | | | | | | | | | | | | | | | | Duh. Fixes issues identified by Klocwork analysis: Pointer 'table' returned from call to function 'calloc' at line 115 may be NULL and will be dereferenced at line 117. and Suspicious dereference of pointer 'table' before NULL check at line 119. NOTE: This is a candidate for the stable branches. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* mesa: Convert the hash table for GL object ids to the open-addressing hash.Eric Anholt2012-11-121-258/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | The previous 1023-entry chaining hash table never resized, so it was very inefficient when there were many objects live. While one could have an even more efficient implementation than this (keep an array for genned names with packed IDs, or take advantage of the fact that key == hash or key == *(uint32_t *)data to store less data), this is fairly fast, and I want a nice replacement hash table for other parts of Mesa, too. It improves Minecraft performance 12.3% +/- 1.4% (n=9), dropping hash lookups from 8% of the profile to 0.5%. I also tested cairo-gl, which should be a pessimal workload for this hash table: around 247000 FBOs created and destroyed, only around 65 live at any time, and few lookups of them between creation and destruction. No statistically significant performance difference at n=76 (mean 20.3/20.4 seconds, sd 2.8/3.2 seconds). If I remove the >20 seconds outliers that appear to be due to thermal throttling, there's possibly a .97% +/- 0.31% performance win (n=61/59). The choice of cutoff for outliers feels a lot like cooking the data, but I've gone through this process 3 times for minor iterations of the code with the same conclusion each time.
