[Spice-devel] [spice-server PATCH v1 0/3] memory pool limit on char-device

[Victor Toso]

Hi folks,

While trying webdav, a few issues came up related on memory usage in
the server/host side. This series should help on spice side by defining
a limit to the memory pool queue in the char-device.

The memory pool can increase greatly after sharing big files with
webdav. Besides establishing a limit to the memory pool, the third patch
frees the memory pool queue after last client disconnect.

This does not fix the problem entirely; massif shows some huge memory
usage on QEMU as well and this should be further investigate.

It also make sense to limit the amount of data that we keep in the
write queue of char-device; At some point in the massif ouput the write
queue reached 240M.

Victor Toso (3):
  char-device: fix usage of free/unref on WriteBuffer
  char-device: Define a memory pool limit
  char-device: free all memory pool when no clients
