From 4486f4523f6671841ffa65ce2419b9e3e018ad76 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 13 Feb 2020 00:21:50 -0800 Subject: qemuarm: Disable highmem when QB_MACHINE is virt running ptests on qemuarm returns fails since it finds errors in kernel logs like below *********************** Central error: [ 4.338465] pci-host-generic 4010000000.pcie: ECAM ioremap failed *********************** Since its a 32bit kernel 4010000000 address is truncated to 10000000 and ends up in conflicts with VIRT_PCIE_MMIO, which ranges from 0x10000000 to 0x3efeffff This is happening because the linux-yocto kernel is not compiled with LPAE support, however, virt machine for qemuarm assumes that by default Should LPAE be enabled by default in kernel config is a separate question Signed-off-by: Khem Raj Signed-off-by: Richard Purdie --- meta/conf/machine/qemuarm.conf | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'meta/conf') diff --git a/meta/conf/machine/qemuarm.conf b/meta/conf/machine/qemuarm.conf index 26f40b14194..367fcef0192 100644 --- a/meta/conf/machine/qemuarm.conf +++ b/meta/conf/machine/qemuarm.conf @@ -11,7 +11,7 @@ SERIAL_CONSOLES ?= "115200;ttyAMA0 115200;hvc0" # For runqemu QB_SYSTEM_NAME = "qemu-system-arm" -QB_MACHINE = "-machine virt" +QB_MACHINE = "-machine virt,highmem=off" QB_CPU = "-cpu cortex-a15" # Standard Serial console QB_KERNEL_CMDLINE_APPEND = "console=ttyAMA0" -- cgit 1.2.3-korg
