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 (From OE-Core rev: 4486f4523f6671841ffa65ce2419b9e3e018ad76) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
