On T2 Macs, the secure boot is handled by the T2 Chip. If enabled, only macOS and Windows are allowed to boot on these machines. Thus we need to disable secure boot for Linux. If we boot into Linux after disabling secure boot, if CONFIG_LOAD_UEFI_KEYS is enabled, EFI Runtime services fail to start, with the following logs in dmesg
..
+static const struct dmi_system_id uefi_apple_ignore[] = {
- {
.matches = {DMI_MATCH(DMI_BOARD_VENDOR, "Apple Inc."),DMI_MATCH(DMI_PRODUCT_NAME, "MacBookPro15,1"),},
I think I'd use: #define xxx(vendor, product) \ .matches = { DMI_MATCH(DMI_BOARD_VENDOR, vendor), \ DMI_MATCH(DMI_PRODUCT_NAME, product), \ } somewhere with a suitable name (bikeshed blue) to reduce the code size of this table.
