[Qemu-devel] [PATCH v3 0/8] qcow2 L2/refcount cache improvements |
Date: |
Mon, 11 May 2015 15:54:52 +0300 |
New version of the qcow2 cache patches:
v3:
- Removed a dead comment in patch #3
- New document explaining how to configure the cache sizes
v2: https://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg00833.html
- Don't do pointer arithmetic on void *
- Rename table_addr() to qcow2_cache_get_table_addr()
- Add qcow2_cache_get_table_idx()
- Cast cache size to size_t to prevent overflows
- Make qcow2_cache_put() a void function
- Don't store the cluster size in the cache, get it from the BDS instead
v1: https://lists.nongnu.org/archive/html/qemu-devel/2015-04/msg04355.html
Regards,
Berto

qcow2: use an LRU algorithm to replace entries from the L2 cache
qcow2: remove qcow2_cache_find_entry_to_replace()
qcow2: use a hash to look for entries in the L2 cache
qcow2: make qcow2_cache_put() a void function
