After reading this paper [1], I wondered whether how far one
could push the idea of dynamic TLB resizing. We discussed
it briefly in this thread:
https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg02340.html
Since then, (1) rth helped me (thanks!) with TCG backend code,
and (2) I've abando
Perform the resizing only on flushes, otherwise we'd
have to take a perf hit by either rehashing the array
or unnecessarily flushing it.
We grow the array aggressively, and reduce the size more
slowly. This accommodates mixed workloads, where some
processes might be memory-heavy while others are n

Currently we evict an entry to the victim TLB when it doesn't match
the current address. But it could be that there's no match because
the current entry is invalid. Do not evict the entry to the vtlb
in that case.
This change will help us keep track of the TLB's use rate.

Hi everyone,
In response to a previous email of mine here:

I would like to share that I have added support for a new
virtio-vhost-user transport to SPDK. and have a working demo of the SPDK
vhost-scsi target over this transport. I ha
Hi Pawel,
Thank you for your quick reply. I appreciate your help.
I’m sorry for the late response. I am glad to tell you that I have a
working demo at last. I have managed to solve my problem.

Use %zu instead of %zd for unsigned numbers.
This fixes two error messages from the LSTM static code analyzer:
This argument should be of type 'ssize_t' but is of type 'unsigned long'

When migrate_add_blocker failed, the invtsc_mig_blocker is not
appended so no need to remove. This can save several instructions.
