HV Calls Table Offset

(preliminary table, please help to fill in/expand)

  • The address of HV table is stored at -0x6FC8(HSPRG0).
  • The address of HV table size is stored at -0x6FD0(HSPRG0).
Function Notes 3.55 offset 3.41 offset 3.15 offset 3.10 offset 3.01 offset 2.76 offset
HV Syscall Table Offset to HV Syscall Table from base HV addr. e.g. if you map HV to HV_LV2_BASE_ADDR the Table would be at HV_LV2_BASE_ADDR+0x00365888. 0x00365888 0x00361b08 0x00363a08
set_lv1_hvcall_table This function sets pointer to HV Call Table and the size of HV Call Table in HSPRG context of a LPAR. 0x002C2B4C 0x002C02B4 0x002C1F04
set_lv1_hvcall_table_entry_invalid This function initializes an entry in HV Call Table to the Invalid HV Call function. 0x002C2B70 0x002C02D8 0x002C1F28
lv1_mm_call function table Each entry is a pointer to a function TOC entry. Size = 256 0x00366088 0x00362308 0x00364208
