[Qemu-devel] [PATCH v6 0/3] Dynamic TLB sizing

Posted by Emilio G. Cota 6 years, 9 months ago

v5: https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg03708.html

Changes since v5:

- Drop quadrupling of TLB size when use rate == 100%.

- Limit TLB max sizes for 32 and 64-bit hosts, as suggested by rth.

- Handle failure when allocating the new TLB, as suggested by rth.
  Add a loop that halves the allocation size until the allocations
  succeed.

Performance numbers are in the last patch.
