RE: [BUG] Xen build for RCAR failing

["Manikandan Chockalingam (RBEI/ECF3)" <Manikandan.Chockalingam@xxxxxxxxxxxx>]

Hello Bertrand,

I tried to build Xen on RCAR with the following build configuration.

Build Configuration:
BB_VERSION        = "1.30.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "universal"
TARGET_SYS        = "aarch64-poky-linux"
MACHINE           = "salvator-x"
DISTRO            = "poky"
DISTRO_VERSION    = "2.1.2"
TUNE_FEATURES     = "aarch64 cortexa57-cortexa53"
TARGET_FPU        = ""
SOC_FAMILY        = "rcar-gen3:r8a7795"
meta              
meta-poky         
meta-yocto-bsp    = "tmp:cca8dd15c8096626052f6d8d25ff1e9a606104a3"
meta-rcar-gen3    = "tmp:95cb48ba09bc7e55fd549817e3e26723409e68d5"
meta-linaro-toolchain 
meta-optee        = "tmp:2f51d38048599d9878f149d6d15539fb97603f8f"
meta-oe           = "tmp:55c8a76da5dc099a7bc3838495c672140cedb78e"
meta-virtualization = "morty:f3643212c2a87a29e2c8066a1a544612d1598de8"
meta-selinux      = "jethro:4c75d9cbcf1d75043c7c5ab315aa383d9b227510"
meta-networking   
meta-python       = "tmp:55c8a76da5dc099a7bc3838495c672140cedb78e"
meta-rcar-gen3-xen = "master:affeba788534a04dd30a21dbbb81a573bd033dfa"

Also enabled the early printk in xen 4.7 and I could able to boot Xen and Dom0.

But I couldn’t enter into the command prompt of Dom0. Attaching the complete 
log for your reference.

I could execute the special keys(0,q,e,R) in xen console. But even after 
enabling hvc0 in Dom0 commandline, am not seeing any logs after a point and I 
couldn’t do any operation on Dom0.

Am I missing something here. Thanks in advance.

Mit freundlichen Grüßen / Best regards

Your DOM0 is probably trying to use the wrong console.
You should add “console=hvc0” to your Dom0 linux command line (and remove any 
other console= argument)
