From 51abffddc77897fc266682be16e7f468613c2216 Mon Sep 17 00:00:00 2001 From: Jérémy Fanguède Date: Thu, 18 Jul 2019 17:17:30 +0200 Subject: meta-rcar-gen3: Add Xen specific device tree for m3ulcb MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Provide a specific version of the device tree (appended with -xen) to run with Xen. Only the R-Car m3ulcb board is supported and tested so far. Add also the Xen block device backend support in the kernel, to be able to run block device based DomU. From U-Boot, Xen and Linux Dom0 can be run as follows (assuming binaries are in sdcard first partition): > setenv bootargs > fatload mmc 0:1 0x48080000 xen-m3ulcb.uImage > fatload mmc 0:1 0x48000000 r8a7796-m3ulcb-xen.dtb > fatload mmc 0:1 0x7a000000 Image-m3ulcb.bin > bootm 0x48080000 - 0x48000000 The Linux Dom0 bootargs are hardcoded in the device tree, the rootfs is expected to be on /dev/mmcblk1p2 Bug-AGL: SPEC-2912 Change-Id: Ia86e0789650eaf79d13691cf4f53755c8cb8f06c Signed-off-by: Jérémy Fanguède --- meta-agl-bsp/meta-rcar-gen3/recipes-kernel/linux/files/xen-be.cfg | 1 + 1 file changed, 1 insertion(+) create mode 100644 meta-agl-bsp/meta-rcar-gen3/recipes-kernel/linux/files/xen-be.cfg (limited to 'meta-agl-bsp/meta-rcar-gen3/recipes-kernel/linux/files/xen-be.cfg') diff --git a/meta-agl-bsp/meta-rcar-gen3/recipes-kernel/linux/files/xen-be.cfg b/meta-agl-bsp/meta-rcar-gen3/recipes-kernel/linux/files/xen-be.cfg new file mode 100644 index 000000000..c9fc6d756 --- /dev/null +++ b/meta-agl-bsp/meta-rcar-gen3/recipes-kernel/linux/files/xen-be.cfg @@ -0,0 +1 @@ +CONFIG_XEN_BLKDEV_BACKEND=y -- cgit 1.2.3-korg
