From 6f24a70ed9323a89cb9d0e6c56bacb6a59e2c31f Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Tue, 28 Jul 2020 19:28:52 -0700 Subject: qemumips: Use 34Kf CPU emulation Few years ago we switched to using mips32r2 tunings for qemumips however the default CPU emulation still remained 24Kf which is not optimal for mips32r2 ISA for qemu [1], therefore switch to recommended 32Kf for CPU emulation when running qemu in system mode Boot time to console is ~1s faster with this setting, hopefully this should speed up qemumips in general [1] https://www.qemu.org/docs/master/system/target-mips.html#preferred-cpu-models-for-mips-hosts Signed-off-by: Khem Raj Signed-off-by: Richard Purdie (cherry picked from commit e68d2afd4a5529437824b5d6b9a2077c2fefd337) Signed-off-by: Steve Sakoman --- meta/conf/machine/qemumips.conf | 2 ++ 1 file changed, 2 insertions(+) (limited to 'meta/conf') diff --git a/meta/conf/machine/qemumips.conf b/meta/conf/machine/qemumips.conf index 31ad754483..4617c3c7b6 100644 --- a/meta/conf/machine/qemumips.conf +++ b/meta/conf/machine/qemumips.conf @@ -12,3 +12,5 @@ KERNEL_ALT_IMAGETYPE = "vmlinux.bin" SERIAL_CONSOLES ?= "115200;ttyS0 115200;ttyS1" QB_SYSTEM_NAME = "qemu-system-mips" + +QB_CPU = "-cpu 34Kf" -- cgit 1.2.3-korg
