* xen-boot-cmd.inc: Fix initrd boot issue with 6.6 kernelSandeep Gundlupet Raju2024-02-221-2/+2
| | | | | | | | | | Due to increase in 6.6 kernel image size xen ramdisk offset was overlapping with kernel image. This causes xen randisk image boot failures. Hence increase the ramdisk offset to fix initrd boot issue. Signed-off-by: Sandeep Gundlupet Raju <sandeep.gundlupet-raju@amd.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>

* xen, raspberry pi: replace linux-yocto-dev with linux-yocto 5.15Christopher Clark2022-05-252-8/+6
| | | | | | | | | | | | | The default preferred Linux kernel for Xen on the Raspberry Pi 4 is linux-yocto. The alternative provided option is linux-yocto-dev, but this is unintentionally a branch tracking configuration rather than a fixed revision. Remove the linux-yocto-dev in favour of the linux-yocto kernel version 5.15 which has been tested and verified working on the board.

* xen, rpi4: Use PARTUUID for rootfs discoveryluca fancellu2021-10-081-4/+7
| | | | | | | | | | | | | | | | | | | The mmc probing order has become unpredictable due to recent linux kernel changes, therefore devices like the raspberry pi that have two mmc interface most of the time can't boot from the hard-coded root path. Modify the u-boot script to fetch the PARTUUID of the second partition of the sd card and use it to put root=PARTUUID=<xxx> in the command line passed to the dom0 kernel.

* global: overrides syntax conversionBruce Ashfield2021-08-022-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
