[PATCH 0/1] MR2622: ntdll: Use log-linear bucketing for free lists.
by Tatsuyuki Ishi (＠ishitatsuyuki) April 10, 2023

April 10, 2023

Currently, the free list consists of a "small list" for sizes below 256, which are linearly spaced, and a "large list" which is manually split into a few chunks. This patch replaces it with a single log-linear policy, while expanding the range the large list covers. The old implementation had issues when a lot of large allocations happened. In this case, all the allocations went in the last catch-all bucket in the "large list", and what happens is: 1. The linked list grew in size over time, causing searching cost to skyrocket. 2. With the first-fit allocation policy, fragmentation was also making the problem worse. The new bucketing covers the entire range up until we start allocating large blocks, which will not enter the free list. It also makes the allocation policy closer to best-fit (although not exactly), reducing fragmentation. The increase in number of free lists does incur some cost when it needs to be skipped over, but the improvement in allocation performance outweighs it. For future work, these ideas (mostly from glibc) might or might not benefit performance: - Use an exact best-fit allocation policy. - Add a bitmap for freelist, allowing empty lists to be skipped with a single bit scan.

[PATCH v3 0/1] MR2032: winex11: Allow replacing either context in wglShareLists.
by Alex Henrie (＠alexhenrie) April 9, 2023

April 9, 2023

The deleted test is a bad test: The behavior is different on different drivers, for example, the test fails on the Windows 10 and 11 testbot machines that have AMD video cards. Furthermore, MSDN does not say that the destination context "must not" have any display lists yet but rather that it "should not" have any.[1] The Khronos OpenGL Wiki similarly advises against calling wglShareLists after the source or destination context has at least one object, but if you do, it only says that "there is a chance that wglShareLists will fail", not that it will necessarily fail.[2] Since there's no clear "right" behavior here, we can adopt the more permissive behavior that some programs expect, as long as it doesn't corrupt the context.
