resolve_seg_reg

Name:solve_seg_reg() - obtain segment register index*@insn: Instruction with operands*@regs: Register values as seen when entering kernel mode*@regoff: Operand offset, in pt_regs, used to deterimine segment register* Determine the segment register associated

Proto:static int resolve_seg_reg(struct insn *insn, struct pt_regs *regs, int regoff)

Type:int

Parameter:

Type	Parameter	Name
struct insn *	insn
struct pt_regs *	regs
int	regoff

268

If regoff == offsetof(structpt_regs, ip) Then

269

If user_64bit_mode(regs) Then Return Identifiers for segment registers

271

Else Return INAT_SEG_REG_CS

275

If Not insn Then Return -EINVAL

278

If Not heck_seg_overrides() - check if segment override prefixes are allowed*@insn: Valid instruction with segment override prefixes*@regoff: Operand offset, in pt_regs, for which the check is performed* For a particular register used in register-indirect Then Return solve_default_seg() - resolve default segment register index for an operand*@insn: Instruction with opcode and address size

281

idx = get_seg_reg_override_idx() - obtain segment register override index*@insn: Valid instruction with segment override prefixes* Inspect the instruction prefixes in @insn and find segment overrides, if any

282

If idx < 0 Then Return idx

285

If idx == INAT_SEG_REG_DEFAULT Then Return solve_default_seg() - resolve default segment register index for an operand*@insn: Instruction with opcode and address size

292

If user_64bit_mode(regs) Then

293

If idx != INAT_SEG_REG_FS && idx != INAT_SEG_REG_GS Then idx = Identifiers for segment registers

298

Return idx
