Richard Fuchs	95f75d690b	MT#55283 use embedded links in bufferpool ... Avoids repeated calls to allocator Change-Id: I2b85fef3d0fd976bc9bf8a4b0cb9b29b62318cbf	2 months ago
Richard Fuchs	58054f2c0f	MT#55283 use typed queue for bpool shards ... Change-Id: Iebe8286a930add93a179cbf0dabc08ea23152f37	2 months ago
Richard Fuchs	0551c2549a	MT#55283 obsolete bufferpool shard array ... Remove the sorted pointer array and the associated lock. We can now directly look up the shard associated with a particular memory block and so this isn't needed any more. Change-Id: I6b2972c3b8837cdabdf92cf957c69dc2d559a06c	2 months ago
Richard Fuchs	d43575dc06	MT#55283 look up bufferpool shard from metadata ... Use the pointer we stored as metadata to quickly look up the respective shard. Change-Id: I01c39d9dbe229bb9bd98d90efb95adfe076e426d	2 months ago
Richard Fuchs	69e634f94a	MT#55283 store metadata head pointer ... Put a pointer to the shard itself in the beginning of the buffer. This facilitates quick lookup. Change-Id: I0109d77e56afac3189775dd708970288f175dfe6	2 months ago
Richard Fuchs	9bd5670f89	MT#55283 use fixed allocation size ... Allocate all bufferpool shards of the same size, regardless of underlying allocator. This way increase memory usage a bit, but we're already quite heavy on that, so no big deal. Change-Id: Icbe09cd2f9b33bc58ab1efe7de293dea00236fec	2 months ago
Richard Fuchs	1a837e6ab1	MT#55283 add `empty` pointer ... With this we can reserve some head room to store our own metadata. Change-Id: I525c2df7db85ce22c0a4a9810e4c75fdd7731c0c	2 months ago
Richard Fuchs	5f9e43b3e0	MT#55283 move alignment macros to header file ... Change-Id: I266cbefe8351f77399bb6e50b2122f9a45249529	2 months ago
Richard Fuchs	1a98502a1b	MT#55283 used aligned memory for bufferpool ... Use allocators that return memory blocks aligned to the requested size, instead of generic malloc. This makes it easier to play tricks with the memory blocks. Change-Id: Iad4b1127c76e48c2e9b4ad8489118d4883a24f6a	2 months ago
Richard Fuchs	ef7aa06801	MT#55283 shorten lock duration ... We can do the freeing safely after having removed the shard from the list. Change-Id: I15d7ec71b0c44b916571c420b07c715ad2feaf50	2 months ago
Richard Fuchs	ad8ce3541d	MT#61822 add RWLOCK_STATIC_INIT ... Change-Id: I6718df967b70554a32c3caddcb4e29af4fb6d7f0	4 months ago
Richard Fuchs	872c06d1cc	MT#55283 add bufferpool implementation ... Manages a pool of bump allocators that allow re-use of buffers after they become empty Change-Id: Id677a2e18b39c2261b8ceae31056d4ad9125bf2c	1 year ago
