From 89974523346abad6c9a67d99e3ae0fe1385a5ecb Mon Sep 17 00:00:00 2001 From: Ilya Leoshkevich Date: Wed, 31 Jul 2024 16:45:20 +0200 Subject: bsd-user/main: Allow setting tb-size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit While qemu-system can set tb-size using -accel tcg,tb-size=n, there is no similar knob for qemu-bsd-user. Add one in a way similar to how one-insn-per-tb is already handled.

Note: Upstream (blitz) commit also did new threads, but that code isn't in qemu project repo yet.
