Subject: [Buildroot] [PATCH v5 2/4] package/xen: add custom version support
Date: Wed, 26 Aug 2026 07:46:47 +0100	[thread overview]
Message-ID: <20260826064649.292291-2-neal.frager@amd.com> (raw)
In-Reply-To: <20260826064649.292291-1-neal.frager@amd.com>

Add the ability to configure specific Xen versions while leaving the default
version unchanged to avoid breaking any builds already using Xen 4.21.1.

To test:
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y
BR2_PACKAGE_XEN=y
BR2_PACKAGE_XEN_CUSTOM_VERSION=y
BR2_PACKAGE_XEN_CUSTOM_VERSION_VALUE="4.22.0"

Add to package/xen/xen.hash:
sha256  b2a14ca369e3cf26f123a455b1603f3962ae9fcee0b8640a9cc33879de198223  xen-4.22.0.tar.gz
