x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.

x86/decoder: Fix bsr/bsf/jmpe decoding with operand-size prefix Fix the x86 instruction decoder to decode bsr/bsf/jmpe with operand-size prefix (66h). This fixes the test case failure reported by Linus, attached below. bsf/bsr/jmpe have a special encoding. Opcode map in Intel Software Developers Manual vol2 says they have TZCNT/LZCNT variants if it has F3h prefix. However, there is no information if it has other 66h or F2h prefixes. Current instruction decoder supposes that those are bad instructions, but it actually accepts at least operand-size prefixes. H. Peter Anvin further explains: " TZCNT/LZCNT are F3 + BSF/BSR exactly because the F2 and F3 prefixes have historically been no-ops with most instructions. This allows software to unconditionally use the prefixed versions and get TZCNT/LZCNT on the processors that have them if they don't care about the difference. " This fixes errors reported by test_get_len: Warning: arch/x86/tools/test_get_len found difference at <em_bsf>:ffffffff81036d87 Warning: ffffffff81036de5: 66 0f bc c2 bsf %dx,%ax Warning: objdump says 4 bytes, but insn_get_length() says 3 Warning: arch/x86/tools/test_get_len found difference at <em_bsr>:ffffffff81036ea6 Warning: ffffffff81036f04: 66 0f bd c2 bsr %dx,%ax Warning: objdump says 4 bytes, but insn_get_length() says 3 Warning: decoded and checked 13298882 instructions with 2 warnings Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Reported-by: Pekka Enberg <penberg@kernel.org> Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: "H.

x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.

x86: Add AMD prefetch and 3DNow! opcodes to opcode map Add AMD prefetch and 3DNow! opcode including FEMMS. Since 3DNow! uses the last immediate byte as an opcode extension byte, x86 insn just treats the extenstion byte as an immediate byte instead of a part of opcode (insn_get_opcode() decodes first "0x0f 0x0f" bytes.) Users who are interested in analyzing 3DNow! opcode still can decode it by analyzing the immediate byte.

This version introduces instruction attributes for decoding instructions.

x86/decoder: Fix bsr/bsf/jmpe decoding with operand-size prefix Fix the x86 instruction decoder to decode bsr/bsf/jmpe with operand-size prefix (66h). This fixes the test case failure reported by Linus, attached below. bsf/bsr/jmpe have a special encoding. Opcode map in Intel Software Developers Manual vol2 says they have TZCNT/LZCNT variants if it has F3h prefix. However, there is no information if it has other 66h or F2h prefixes. Current instruction decoder supposes that those are bad instructions, but it actually accepts at least operand-size prefixes. H. Peter Anvin further explains: " TZCNT/LZCNT are F3 + BSF/BSR exactly because the F2 and F3 prefixes have historically been no-ops with most instructions. This allows software to unconditionally use the prefixed versions and get TZCNT/LZCNT on the processors that have them if they don't care about the difference.

x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.

x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.

x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.

x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.
