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-agl-bsp/conf/include/agl_raspberrypi4.inc | 9 ++++ .../recipes-bsp/bootfiles/rpi-config_git.bbappend | 5 +++ .../recipes-bsp/rpi-u-boot-scr/files/boot_xen.cmd | 45 +++++++++++++++++++ .../rpi-u-boot-scr/rpi-u-boot-scr.bbappend | 18 ++++++++ .../files/0002-Disable-DMA-in-sdhci-driver.patch | 25 +++++++++++ .../files/0003-Fix-PCIe-in-dom0-for-RPi4.patch | 31 ++++++++++++++ .../recipes-kernel/linux/files/xen-be.cfg | 50 ++++++++++++++++++++++ .../linux/linux-raspberrypi_%.bbappend | 10 +++++ .../linux/linux-raspberrypi_4.19.bbappend | 16 +++++++ ...-1GB-lmitation-workaround-XEN-tries-to-al.patch | 28 ++++++++++++ .../recipes-extended/xen/xen-mkimage-rpi4.bb | 29 +++++++++++++ .../recipes-extended/xen/xen-mkimage.bb | 29 ------------- .../recipes-extended/xen/xen-tools_git.bbappend | 11 +++++ .../recipes-extended/xen/xen_git.bbappend | 18 ++++++-- 14 files changed, 292 insertions(+), 32 deletions(-) create mode 100644 meta-agl-bsp/meta-raspberrypi/recipes-bsp/rpi-u-boot-scr/files/boot_xen.cmd create mode 100644 meta-agl-bsp/meta-raspberrypi/recipes-bsp/rpi-u-boot-scr/rpi-u-boot-scr.bbappend create mode 100644 meta-agl-bsp/meta-raspberrypi/recipes-kernel/linux/files/0002-Disable-DMA-in-sdhci-driver.patch create mode 100644 meta-agl-bsp/meta-raspberrypi/recipes-kernel/linux/files/0003-Fix-PCIe-in-dom0-for-RPi4.patch create mode 100644 meta-agl-bsp/meta-raspberrypi/recipes-kernel/linux/files/xen-be.cfg create mode 100644 meta-agl-bsp/virtualization-layer/recipes-extended/xen/files/0001-XEN-on-RPi4-1GB-lmitation-workaround-XEN-tries-to-al.patch create mode 100644 meta-agl-bsp/virtualization-layer/recipes-extended/xen/xen-mkimage-rpi4.bb delete mode 100644 meta-agl-bsp/virtualization-layer/recipes-extended/xen/xen-mkimage.bb create mode 100644 meta-agl-bsp/virtualization-layer/recipes-extended/xen/xen-tools_git.bbappend diff --git a/meta-agl-bsp/conf/include/agl_raspberrypi4.inc b/meta-agl-bsp/conf/include/agl_raspberrypi4.inc index b91c330f2..ae302aae1 100644 --- a/meta-agl-bsp/conf/include/agl_raspberrypi4.inc +++ b/meta-agl-bsp/conf/include/agl_raspberrypi4.inc @@ -17,3 +17,12 @@ IMAGE_FEATURES_remove = "splash" # Build updatable image.
