From d151cc20af79c89383ffacc89c1f646f831fc3e6 Mon Sep 17 00:00:00 2001 From: Daniel Battaiola Kreling <dbkreling@br.ibm.com> Date: Mon, 7 Oct 2013 11:51:50 +0530 Subject: [PATCH] GPT: add support for PReP GUID PReP (PowerPC Reference Platform) boot partition is the first partition used in PowerPC platform for containing the bootable kernel or bootloader. The firmware searches for this partition and jumps to it for booting. So far no GUID was specified for this partition type and hence booting from GPT disk was not supported on this platform. A new GUID 9e1a2d38-c612-4316-aa26-8b49521e5a8b for PReP partition is proposed to be included in GPT. --- NEWS | 7 +++++++ doc/parted.texi | 2 +- libparted/labels/gpt.c | 38 ++++++++++++++++++++++++++++++++++++++ 3 files changed, 46 insertions(+), 1 deletion(-) Index: parted-3.1/NEWS =================================================================== --- parted-3.1.orig/NEWS +++ parted-3.1/NEWS @@ -1,5 +1,12 @@ GNU parted NEWS -*- outline -*- +* Noteworthy changes post release 3.1 + +** New features + + Add support for prep flag to GPT to select PowerPC Reference Platform + boot partition type. + * Noteworthy changes in release 3.1 (2012-03-02) [stable] ** New features Index: parted-3.1/doc/parted.texi =================================================================== --- parted-3.1.orig/doc/parted.texi +++ parted-3.1/doc/parted.texi @@ -822,7 +822,7 @@ physical volume. by the Linux/PA-RISC boot loader, palo. @item PREP -(MS-DOS) - this flag can be enabled so that the partition can be used +(MS-DOS, GPT) - this flag can be enabled so that the partition can be used as a PReP boot partition on PowerPC PReP or IBM RS6K/CHRP hardware. @item DIAG Index: parted-3.1/libparted/labels/gpt.c =================================================================== --- parted-3.1.orig/libparted/labels/gpt.c +++ parted-3.1/libparted/labels/gpt.c @@ -142,6 +142,10 @@ typedef struct ((efi_guid_t) { PED_CPU_TO_LE32 (0x5265636F), PED_CPU_TO_LE16 (0x7665), \ PED_CPU_TO_LE16 (0x11AA), 0xaa, 0x11, \ { 0x00, 0x30, 0x65, 0x43, 0xEC, 0xAC }}) +#define PARTITION_PREP_GUID \ + ((efi_guid_t) { PED_CPU_TO_LE32 (0x9e1a2d38), PED_CPU_TO_LE16 (0xc612), \ + PED_CPU_TO_LE16 (0x4316), 0xaa, 0x26, \ + { 0x8b, 0x49, 0x52, 0x1e, 0x5a, 0x8b }}) #define PARTITION_IRST_GUID \ ((efi_guid_t) { PED_CPU_TO_LE32 (0xD3BFE2DE), PED_CPU_TO_LE16 (0x3DAF), \ PED_CPU_TO_LE16 (0x11DF), 0xba, 0x40, \ @@ -287,6 +291,7 @@ typedef struct _GPTPartitionData int atvrecv;
