You received this bug notification because you are a member of qemu-
devel-ml, which is subscribed to QEMU.
The current cache algorithm traverses the array starting always from
the beginning, so the average number of comparisons needed to perform
a lookup is proportional to the size of the array.
By using a hash of the offset as the starting point, lookups are
faster and independent from the array
New version of the qcow2 cache patches:
v2:
- 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 qcow2 L2/refcount cache contains one separate table for each cache
entry. Doing one allocation per table adds unnecessary overhead and it
also requires us to store the address of each table separately.
Since the size of the cache is constant during its lifetime, it's
better to have an array

The original assumption was that this was not a problem because discards
are only cached during discard/write zeroes operations, which are
synchronous so that no
A cache miss means that the whole array was traversed and the entry
we were looking for was not found, so there's no need to traverse it
again in order to select an entry to replace.

When I try to use the pcspk sound hardware, QEMU freezes and uses 100% of the

Hi, all:
I've been trying to understand the process of address translation inside QEMU,

Hi Peter and all,
Xilinx's next gen SoC has been announced. This series adds a SoC and

Series start with addition of ARM cortex A53 support (P1 and P2). The
Soc skeleton is then added with GIC, EMACs and UARTs added. The
