From 4028c726be78adc1f1df3708dbe99f9eb2303790 Mon Sep 17 00:00:00 2001 From: Leonid Lazarev Date: Fri, 15 May 2020 11:51:48 +0300 Subject: Raspberry 4: XEN support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added the support for DOM0 in raspberry pi4. The feature agl-virt-xen should be enabled to activate this code. 1512 MB of memory is used for DOM0 machine. There are limitations: - brcmfmac module disabled (bluethooth and Wifi) due to the crash - total_memory is set to the 3Gb, as it impacts the USB ports on rasbperry pi4 on Linux kernel 4.19 v2 (jsmoeller): make changes in virtualization-layer conditional to raspberrypi4 Bug-AGL: SPEC-3259 Change-Id: I873fbf1f5498e31ae5f468407502f16e1873f7fc Signed-off-by: Leonid Lazarev Signed-off-by: Jan-Simon Möller Reviewed-on: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/24522 Tested-by: Jenkins Job builder account ci-image-build: Jenkins Job builder account ci-image-boot-test: Jenkins Job builder account --- .../meta-raspberrypi/recipes-bsp/bootfiles/rpi-config_git.bbappend | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'meta-agl-bsp/meta-raspberrypi/recipes-bsp/bootfiles/rpi-config_git.bbappend') diff --git a/meta-agl-bsp/meta-raspberrypi/recipes-bsp/bootfiles/rpi-config_git.bbappend b/meta-agl-bsp/meta-raspberrypi/recipes-bsp/bootfiles/rpi-config_git.bbappend index 5eecff6f1..9891fa200 100644 --- a/meta-agl-bsp/meta-raspberrypi/recipes-bsp/bootfiles/rpi-config_git.bbappend +++ b/meta-agl-bsp/meta-raspberrypi/recipes-bsp/bootfiles/rpi-config_git.bbappend @@ -1,4 +1,5 @@ DISABLE_OVERSCAN = "1" +TOTAL_BOARD_MEM = "3072" do_deploy_append_raspberrypi4() { # ENABLE CAN @@ -17,6 +18,10 @@ do_deploy_append_raspberrypi4() { ;; esac fi + + if [ "${AGL_XEN_WANTED}" = "1" ]; then + echo "total_mem=${TOTAL_BOARD_MEM}" >> ${DEPLOYDIR}/bcm2835-bootfiles/config.txt + fi } do_deploy_append() { -- cgit 1.2.3-korg
