Mkisofs/genimageiso now correctly supports El Torito multi boot entries by introducing a Boot Dection Header before a list of alternate boot entries.
New option -eltorito-platform allows to set the El Torito platform id for a boot entry or for a list of boot entries. Supported values for the parameter are: - x86 the standard value vor x86 based PCs - PPC the Power PC platform - Mac The Apple Mac platform - efi EFI based boot for PCs - # an arbitrary numerical value Port implement from cdrtools: https://github.com/jobermayr/cdrtools/commit/a50804fd61d75eb689a515dbfca6968ca2296fd7 Signed-off-by: Hongxu Jia <hongxu....@windriver.com> --- .../cdrkit/cdrkit_1.1.11.bb | 1 + ...001-add-new-option-eltorito-platform.patch | 336 ++++++++++++++++++ 2 files changed, 337 insertions(+) create mode 100644 meta-oe/recipes-multimedia/cdrkit/files/0001-add-new-option-eltorito-platform.patch diff --git a/meta-oe/recipes-multimedia/cdrkit/cdrkit_1.1.11.bb b/meta-oe/recipes-multimedia/cdrkit/cdrkit_1.1.11.bb index dd0405c95..757f99d1f 100644 --- a/meta-oe/recipes-multimedia/cdrkit/cdrkit_1.1.11.bb +++ b/meta-oe/recipes-multimedia/cdrkit/cdrkit_1.1.11.bb @@ -11,6 +11,7 @@ SRC_URI = "${DEBIAN_MIRROR}/main/c/${BPN}/${BPN}_${PV}.orig.tar.gz \ file://0001-define-__THROW-to-avoid-build-issue-with-musl.patch \ file://0002-Do-not-use-rcmd-on-build-with-musl.patch \ file://0001-genisoimage-Add-missing-extern-definition.patch \ + file://0001-add-new-option-eltorito-platform.patch \ " SRC_URI:append:class-nativesdk = " \ file://0001-install-netscsid-to-bin-for-nativesdk.patch \ diff --git a/meta-oe/recipes-multimedia/cdrkit/files/0001-add-new-option-eltorito-platform.patch b/meta-oe/recipes-multimedia/cdrkit/files/0001-add-new-option-eltorito-platform.patch new file mode 100644 index 000000000..c0b0364bb --- /dev/null +++ b/meta-oe/recipes-multimedia/cdrkit/files/0001-add-new-option-eltorito-platform.patch @@ -0,0 +1,336 @@ +From 34de1b83f8000d95a10afcfdb7ec814cd75b12b2 Mon Sep 17 00:00:00 2001 +From: Hongxu Jia <hongxu....@windriver.com> +Date: Mon, 25 Apr 2022 18:18:00 +0800 +Subject: [PATCH] add new option -eltorito-platform + +Mkisofs now correctly supports El Torito multi boot entries by introducing +a Boot Dection Header before a list of alternate boot entries. + +New option -eltorito-platform allows to set the El Torito platform id +for a boot entry or for a list of boot entries.
