- * GMR buffers are typically shortlived, but it's possible that at a given

- * forbid creation of buffers beyond half the GMR pool size,
+ * The slab pool allocates buffers directly from the kernel except
+ * for very small buffers which are allocated from a slab in order
+ * not to waste memory, since a kernel buffer is a minimum 4096 bytes.
*
- * XXX: It is unclear weather we want to limit the total amount of temporary
- * malloc memory used to backup unvalidated GMR buffers. On one hand it is
- * preferrable to fail an allocation than exhausting the guest memory with
- * temporary data, but on the other hand it is possible that a stupid
- * application creates large vertex buffers and does not use them for a long
- * time -- since the svga pipe driver only emits the DMA uploads when a
- * buffer is used for drawing this would effectively disabling swapping GMR
- * buffers to memory. So far, the preemptively flush already seems to keep
- * total allocated memory within relatively small numbers, so we don't
- * limit.
+ * Here we use it only for emergency in the case our pre-allocated
+ * managed buffer pool runs out of memory.
