Detailed Description

Utility routines for identifying features of the processor.

Macro Definition Documentation

◆ DR_FPSTATE_ALIGN

#define DR_FPSTATE_ALIGN 16

The alignment requirements of floating point state buffer.

◆ DR_FPSTATE_BUF_SIZE

#define DR_FPSTATE_BUF_SIZE 512

The maximum possible required size of floating point state buffer for processors with different features (i.e., the processors with the FXSR feature on x86, or the processors with the VFPv3 feature on ARM).

Note: The actual required buffer size may vary depending on the processor feature.; proc_fpstate_save_size() can be used to determine the particular size needed.

Function Documentation

◆ proc_avx512_enabled()

DR_API bool proc_avx512_enabled ( void )

Returns whether AVX-512 is enabled by both the processor and the OS. Even if the processor supports AVX-512, if the OS does not enable AVX-512, then AVX-512 instructions will fault.

◆ proc_avx_enabled()

DR_API bool proc_avx_enabled ( void )

Returns whether AVX (or AVX2) is enabled by both the processor and the OS. Even if the processor supports AVX, if the OS does not enable AVX, then AVX instructions will fault.

◆ proc_bump_to_end_of_cache_line()

DR_API ptr_uint_t proc_bump_to_end_of_cache_line ( ptr_uint_t sz )

Returns n >= sz such that n is a multiple of the cache line size.

Returns the cache line size in bytes of the processor.

◆ proc_get_cache_size_str()

const DR_API char* proc_get_cache_size_str ( cache_size_t size )

Converts a cache_size_t type to a string.

◆ proc_get_containing_page()

DR_API void* proc_get_containing_page ( void * addr )

Returns n <= addr such that n is a multiple of the page size.

◆ proc_get_family()

DR_API uint proc_get_family ( void )

Returns the processor family as given by the cpuid instruction, adjusted by the extended family as described in the Intel documentation. The FAMILY_ constants identify important family values.

◆ proc_get_L1_dcache_size()

DR_API cache_size_t proc_get_L1_dcache_size ( void )

Returns the size of the L1 data cache.

◆ proc_get_L1_icache_size()

DR_API cache_size_t proc_get_L1_icache_size ( void )

Returns the size of the L1 instruction cache.

◆ proc_get_L2_cache_size()

DR_API cache_size_t proc_get_L2_cache_size ( void )

Returns the size of the L2 cache.

◆ proc_get_model()

DR_API uint proc_get_model ( void )

Returns the processor model as given by the cpuid instruction, adjusted by the extended model as described in the Intel documentation. The MODEL_ constants identify important model values.

◆ proc_get_stepping()

DR_API uint proc_get_stepping ( void )

Returns the processor stepping ID.

◆ proc_get_type()

DR_API uint proc_get_type ( void )

Returns the processor type as given by the cpuid instruction.

◆ proc_get_vector_length_bytes()

DR_API uint proc_get_vector_length_bytes ( void )

Returns the size in bytes of the SVE registers' vector length set by the AArch64 hardware implementor. Length can be from 128 to 2048 bits in multiples of 128 bits: 128 256 384 512 640 768 896 1024 1152 1280 1408 1536 1664 1792 1920 2048 Currently DynamoRIO supports implementations of up to 512 bits.

◆ proc_get_vendor()

DR_API uint proc_get_vendor ( void )

Returns one of the VENDOR_ constants.

◆ proc_has_feature()

DR_API bool proc_has_feature ( feature_bit_t feature )

Tests if processor has selected feature.

◆ proc_is_cache_aligned()

DR_API bool proc_is_cache_aligned ( void * addr )

Returns true only if addr is cache-line-aligned.

◆ proc_num_opmask_registers()

DR_API int proc_num_opmask_registers ( void )

Returns the number of AVX-512 mask registers. The number returned here depends on the processor and OS feature bits on a given machine.

◆ proc_num_simd_registers()

DR_API int proc_num_simd_registers ( void )

Returns the number of SIMD registers. The number returned here depends on the processor and OS feature bits on a given machine. For x86 this only includes xmm/ymm/zmm.

◆ proc_num_simd_saved()

DR_API int proc_num_simd_saved ( void )

Returns the number of SIMD registers preserved for a context switch. DynamoRIO may decide to optimize the number of registers saved, in which case this number may be less than proc_num_simd_registers(). For x86 this only includes xmm/ymm/zmm.

The number of saved SIMD registers may be variable. For example, we may decide to optimize the number of saved registers in a context switch to avoid frequency scaling (https://github.com/DynamoRIO/dynamorio/issues/3169).

◆ proc_restore_fpstate()

DR_API void proc_restore_fpstate ( byte * buf )

Restores the x87 floating point state from the buffer buf. On x86, the buffer must be 16-byte-aligned, and it must be 512 (DR_FPSTATE_BUF_SIZE) bytes for processors with the FXSR feature, and 108 bytes for those without (where this routine does not support 16-bit operand sizing). On ARM/AArch64, nothing needs to be restored as the SIMD/FP registers are restored together with the general-purpose registers.

Note: proc_fpstate_save_size() can be used to determine the particular size needed.

When the FXSR feature is present, the fxsave format matches the bitwidth of the ISA mode of the current thread (see dr_get_isa_mode()).

◆ proc_save_fpstate()

DR_API size_t proc_save_fpstate ( byte * buf )

Saves the x87 floating point state into the buffer buf.

On x86, the buffer must be 16-byte-aligned, and it must be 512 (DR_FPSTATE_BUF_SIZE) bytes for processors with the FXSR feature, and 108 bytes for those without (where this routine does not support 16-bit operand sizing). On ARM/AArch64, nothing needs to be saved as the SIMD/FP registers are saved together with the general-purpose registers.

Note: proc_fpstate_save_size() can be used to determine the particular size needed.

When the FXSR feature is present, the fxsave format matches the bitwidth of the ISA mode of the current thread (see dr_get_isa_mode()).

The last floating-point instruction address is left in an untranslated state (i.e., it may point into the code cache).

DR does NOT save the application's x87 floating-point or MMX state on context switches! Thus if a client performs any floating-point operations in its main routines called by DR and cannot prove that its compiler will not use x87 operations, the client must save and restore the x87 floating-point/MMX state. If the client needs to do so inside the code cache the client should implement that itself. Returns number of bytes written.

◆ proc_set_vendor()

DR_API int proc_set_vendor ( uint new_vendor )

Sets the vendor to the given VENDOR_ constant. This function is supplied to support decoding or encoding with respect to other than the current processor being executed on. The change in vendor will be seen by the decoder and encoder, as well as the rest of the system.

Returns: the prior vendor, or -1 on an invalid argument.
