It is now time to get everything to work. Thus implement the hooks required by the linux-kernel target and enable s390's privileged registers. gdb/ChangeLog: * s390-lk-tdep.h: New file. * s390-lk-tdep.c: New file. * Makefile.in (ALL_TARGET_OBS): Add s390-lk-tdep.o. (HFILES_NO_SRCDIR): Add s390-lk-tdep.h. (ALLDEPFILES): Add s390-lk-tdep.c. * configure.tgt (s390*-*-linux*): Add s390-lk-tdep.o. * s390-tdep.h: Define macros for address translation. * s390-tdep.c (s390-lk-tdep.h): New include. (s390_iterate_over_regset_sections): Enable privileged registers. (s390_core_read_description): Enable privileged registers. (s390_gdbarch_init): : Enable privileged registers and adjust. --- gdb/s390-tdep.h | 62 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) (limited to 'gdb/s390-tdep.h') diff --git a/gdb/s390-tdep.h b/gdb/s390-tdep.h index 8d0da72..0df8a27 100644 --- a/gdb/s390-tdep.h +++ b/gdb/s390-tdep.h @@ -319,4 +319,66 @@ enum #define S390_IS_TDBREGSET_REGNUM(i) \ ((i) >= S390_TDB_DWORD0_REGNUM && (i) <= S390_TDB_R15_REGNUM) +/* Definitions for address translation. */ +/* DAT Table types. */ +#define S390_LK_DAT_TT_REGION1 3 +#define S390_LK_DAT_TT_REGION2 2 +#define S390_LK_DAT_TT_REGION3 1 +#define S390_LK_DAT_TT_SEGMENT 0 + +/* Region-First-Table */ +#define S390_LK_RFTE_TL 0x3ULL /* Table-Length */ +#define S390_LK_RFTE_TT 0xcULL /* Table-Type */ +#define S390_LK_RFTE_I 0x20ULL /* Region-Invalid Bit */ +#define S390_LK_RFTE_TF 0xc0ULL /* Table Offset */ +#define S390_LK_RFTE_P 0x200ULL /* DAT-Protection Bit */ +#define S390_LK_RFTE_O ~0xfffULL /* Region-Second-Table Origin */ + +/* Region-Second-Table flags. */ +#define S390_LK_RSTE_TL 0x3ULL /* Table-Length */ +#define S390_LK_RSTE_TT 0xcULL /* Table-Type */ +#define S390_LK_RSTE_I 0x20ULL /* Region-Invalid Bit */ +#define S390_LK_RSTE_TF 0xc0ULL /* Table Offset */ +#define S390_LK_RSTE_P 0x200ULL /* DAT-Protection Bit */ +#define S390_LK_RSTE_O ~0xfffULL /* Region-Third-Table Origin */ + +/* Region-Third-Table flags. */ +#define S390_LK_RTTE_TL 0x3ULL /* Table-Length */ +#define S390_LK_RTTE_TT 0xcULL /* Table-Type */ +#define S390_LK_RTTE_CR 0x10ULL /* Common-Region Bit */ +#define S390_LK_RTTE_I 0x20ULL /* Region-Invalid Bit */ +#define S390_LK_RTTE_TF 0xc0ULL /* Table Offset */ +#define S390_LK_RTTE_P 0x200ULL /* DAT-Protection Bit */ +#define S390_LK_RTTE_FC 0x400ULL /* Format-Control Bit */ +#define S390_LK_RTTE_F 0x800ULL /* Fetch-Protection Bit */ +#define S390_LK_RTTE_ACC 0xf000ULL /* Access-Control Bits */ +#define S390_LK_RTTE_AV 0x10000ULL /* ACCF-Validity Control */ +#define S390_LK_RTTE_O ~0xfffULL /* Segment-Table Origin */ +#define S390_LK_RTTE_RFAA ~0x7fffffffULL /* Region-Frame Absolute Address */ + +/* Segment-Table flags. */ +#define S390_LK_STE_TT 0xcULL /* Table-Type */ +#define S390_LK_STE_I 0x20ULL /* Segment-Invalid Bit */ +#define S390_LK_STE_TF 0xc0ULL /* Table Offset */ +#define S390_LK_STE_P 0x200ULL /* DAT-Protection Bit */ +#define S390_LK_STE_FC 0x400ULL /* Format-Control Bit */ +#define S390_LK_STE_F 0x800ULL /* Fetch-Protection Bit */ +#define S390_LK_STE_ACC 0xf000ULL /* Access-Control Bits */ +#define S390_LK_STE_AV 0x10000ULL /* ACCF-Validity Control */ +#define S390_LK_STE_O ~0x7ffULL /* Page-Table Origin */ +#define S390_LK_STE_SFAA ~0xfffffULL /* Segment-Frame Absolute Address */ + +/* Page-Table flags. */ +#define S390_LK_PTE_P 0x200ULL /* DAT-Protection Bit */ +#define S390_LK_PTE_I 0x400ULL /* Page-Invalid Bit */ +#define S390_LK_PTE_PFAA ~0xfffULL /* Page-Frame Absolute Address */ + +/* Virtual Address Fields. */ +#define S390_LK_VADDR_RFX 0xffe0000000000000ULL +#define S390_LK_VADDR_RSX 0x001ffc0000000000ULL +#define S390_LK_VADDR_RTX 0x000003ff80000000ULL +#define S390_LK_VADDR_SX 0x000000007ff00000ULL +#define S390_LK_VADDR_PX 0x00000000000ff000ULL +#define S390_LK_VADDR_BX 0x0000000000000fffULL + #endif /* S390_TDEP_H */ -- cgit v1.1
