* xtf: add testimage integration to run XTF test cases in OEQAChristopher Clark2021-09-022-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new minimal OEQA test case to run the Xen Test Framework test runner in the standard testimage step. Tested with qemux86-64 and designed for compatibility with Arm when XTF supports it. To enable, append to local.conf: INHERIT += "testimage" QEMU_USE_SLIRP = "1" TEST_SERVER_IP = "127.0.0.1" To run: bitbake -c testimage xtf-image For inspection while it runs, at another shell prompt: * Observe the image booting: tail -f ${TMPDIR}/work/qemux86_64-*/xtf-image/*/testimage/qemu_boot_log.* * Observe the tests running once boot has completed: tail -f ${TMPDIR}/work/qemux86_64-*/xtf-image/*/temp/log.do_testimage The XTF test sequence by default is a single XTF test case with minimal hardware dependency to ensure that Xen is running, the Xen toolstack is functional and XTF works. Additional XTF test cases for an image can be configured via variables that are documented in the OEQA test case: * XTF_TEST_CASES_POPULATE * XTF_TEST_CASES_SKIP * XTF_TEST_CASES_REQUIRE Since testimage requires a functioning network to perform the tests on the image and the qemu MACHINES do not have networking enabled this commit provides a new qemuboot-testimage-network bbclass to add an image postprocess command to enable a functional eth0 for qemu MACHINES.

* xtf-image: update qemuboot settingsChristopher Clark2021-09-021-5/+0
| | | | | | | | | | | | QB_MEM is now set via the qemuboot-xen-defaults bbclass and has the better default value of 512MB, which fixes some test failures observed when using the lower previous default value of 400MB. The SYSLINUX_XEN_ARGS method of setting the intended dom0 memory level did not take effect in practice, so remove it.

* xen-image-minimal: supply bootloader config for qemux86-64 machineChristopher Clark2021-09-021-0/+1
| | | | | | | | | | | | | | | | Add a dedicated bootloader config for the qemux86-64 machine so that the 'pmtmr=0' kernel command line argument can be provided, which removes an error message that otherwise occurs in syslog during boot which is detected by an OEQA test case causing it to fail. A new kickstart file is provided that applies the new bootloader config and it is supplied as an override to WKS_FILE for this image. This is work towards enabling the Xen Test Framework (XTF) in the OEQA testimage framework.

* global: overrides syntax conversionBruce Ashfield2021-08-025-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OEcore/bitbake are moving to use the clearer ":" as an overrides separator. This is pass one of updating the meta-virt recipes to use that syntax. This has only been minimally build/runtime tested, more changes will be required for missed overrides, or incorrect conversions Note: A recent bitbake is required: commit 75fad23fc06c008a03414a1fc288a8614c6af9ca Author: Richard Purdie <richard.purdie@linuxfoundation.org> Date: Sun Jul 18 12:59:15 2021 +0100 bitbake: data_smart/parse: Allow ':' characters in variable/function names It is becomming increasingly clear we need to find a way to show what is/is not an override in our syntax. We need to do this in a way which is clear to users, readable and in a way we can transition to. The most effective way I've found to this is to use the ":" charater to directly replace "_" where an override is being specified. This includes "append", "prepend" and "remove" which are effectively special override directives. This patch simply adds the character to the parser so bitbake accepts the value but maps it back to "_" internally so there is no behaviour change. This change is simple enough it could potentially be backported to older version of bitbake meaning layers using the new syntax/markup could work with older releases. Even if other no other changes are accepted at this time and we don't backport, it does set us on a path where at some point in future we could require a more explict syntax. I've tested this patch by converting oe-core/meta-yocto to the new syntax for overrides (9000+ changes) and then seeing that builds continue to work with this patch.

* qemuboot, xen-image-minimal: enable runqemu for qemuarm64 Xen imagesChristopher Clark2021-07-291-2/+3
| | | | | | | | | | | | | | | | | | | The Xen hypervisor built for Arm 64-bit targets can be launched with runqemu by providing a Device Tree binary and configuration for Qemu, which enables interactive testing of Xen images. Add qemuboot-xen-dtb.bbclass to add a new bitbake task for generating the dtb file by using lopper on a device tree produced by Qemu. Add qemuboot-xen-defaults.bbclass to supply working default parameters for the qemuarm64 machine and general support for qemuboot for Xen, and adjust the defaults as needed to boot successfully in testing.

* container-base: make CONTAINER_SHELL a conditional image installBruce Ashfield2020-11-051-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some scenarios (and package managers), packages post install scripts may have references to /bin/sh. The package manager doesn't know if the scripts will run on the build host or target, so we get a calculated redepnds on /bin/sh base-files and base-passwd fall into this category of having post installs, but no need for /bin/sh on the target. If you know what you are installing, and want the smallest container possible, this package will satisfy the dependency when assembling the rootfs. To enable it, put the following in a configuration file (local.conf or otherwise): PACKAGE_EXTRA_ARCHS_append = " container-dummy-provides" This image will detect if the dummy provides arch is set, and will automatically install the providing recipe, otherwise, busybox is installed. If you have a custom shell or want a different behaviour, the CONTAINER_SHELL variable can be overriden. Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>

* xen: make QB_ assignments weakBruce Ashfield2020-09-161-4/+4
| | | | | | | | | | | | | | runqemu is looking for the QB_DEFAULT_KERNEL to be set to "none" to trigger special processing. The current set of QB_DEFAULT_KERNEL="" won't trigger that behaviour .. so we change the default. We also make the assignments weak, to allow easier overrides in specific implementations. We also need a patch to qemuboot.bbclass to make the defaults ??=, and when that is done, our ?= here will work properly. Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>

* xen: separate recipes for hypervisor and tools; switch to git as sourceChristopher Clark2020-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change changes the names of many packages produced: the xen-tools recipe now builds packages previous built by the xen recipe, so the package prefix changes from "xen-" to "xen-tools-". A temporary bbappend is provided for qemu to ease the transition. Multiple motivations for recipe separation: - improves efficiency of incremental build and development - supports building the hypervisor and tools with different toolchains and for different architectures Switch to using a git recipe on the Xen stable branch: - enables easier tracking of critical XSA security updates applied upstream by just advancing SRCREV along the branch Revision has been set to the tip of the stable-4.12 branch, which has the one XSA-312 patch applied on top of RELEASE-4.12.2. The recipe refactor externalizes the block tap components, to enable optional building of blktap in a separate recipe outside xen-tools, needed by OpenXT. xenstored is made a virtual package to support switching between alternative implementations (several exist). Update xen-image-minimal to install the xen-tools package, which replaces what was previously xen-base. Determine the flask policy filename, which is Xen-version specific, using the same method as the Xen build system. qemu: update PACKAGECONFIG[xen] for xen package renaming: allows builds to continue correctly in the meantime while openembedded core and poky are updated.
