OK, we have a major trainwreck when these patches meet Peter's
get-newsetup.patch.
I'm halfway into fixing it when I see this. You have:
#define SYS_DESC_TABLE (*(struct sys_desc_table_struct*)(PARAM+0xa0))
+#define EFI_LOADER_SIG ((unsigned char *)(PARAM+0x1c0))
+#define EFI_MEMDESC_SIZE (*((unsigned int *) (PARAM+0x1c4)))
+#define EFI_MEMDESC_VERSION (*((unsigned int *) (PARAM+0x1c8)))
+#define EFI_MEMMAP_SIZE (*((unsigned int *) (PARAM+0x1cc)))
+#define EFI_MEMMAP (*((unsigned long *)(PARAM+0x1d0)))
+#define EFI_SYSTAB (*((unsigned long *)(PARAM+0x1d8)))
#define MOUNT_ROOT_RDONLY (*(unsigned short *) (PARAM+0x1F2))
But Peter's include/asm-i386/bootparam.h has:
struct efi_info {
u32 _pad1;
u32 efi_systab;
u32 efi_memdesc_size;
u32 efi_memdesc_version;
u32 efi_memmap;
u32 efi_memmap_size;
u32 _pad2[2];
};
/* The so-called "zeropage" */
struct boot_params {
struct screen_info screen_info; /* 0x000 */
struct apm_bios_info apm_bios_info; /* 0x040 */
u8 _pad2[12]; /* 0x054 */
struct ist_info ist_info; /* 0x060 */
u8 _pad3[16]; /* 0x070 */
u8 hd0_info[16]; /* obsolete! */ /* 0x080 */
u8 hd1_info[16]; /* obsolete! */ /* 0x090 */
struct sys_desc_table sys_desc_table; /* 0x0a0 */
u8 _pad4[144]; /* 0x0b0 */
struct edid_info edid_info; /* 0x140 */
struct efi_info efi_info; /* 0x1c0 */
u32 alt_mem_k; /* 0x1e0 */
So for example, Peter has memdesc_size at 0x1c8 and you have it at 0x1c4.
I'll give up and will drop the EFI patches. I'd suggest that you work with
Peter on getting these patches integrated.
