The "disasm" option in ocloc was not validate new acronyms. despite handling them in "compile". This PR is fixing the issue - ocloc disasm supports new & deprecated acronyms. https://github.com/intel/compute-runtime/issues/582 Signed-off-by: Daria Hinz <daria.hinz@intel.com> Related-To: NEO-7509

Output of such operation is a set of files that can be later used to
|
|
reassemble back a valid Intel Compute GPU device binary (using ocloc 'asm'
|
|
command). This set of files contains:
|
|
Program-scope data :
|
|
- spirv.bin (optional) - spirV representation of the program from which
|
|
the input binary was generated
|
|
- build.bin - build options that were used when generating the
|
|
input binary
|
|
- PTM.txt - 'patch tokens' describing program-scope and
|
|
kernel-scope metadata about the input binary
|
|
|
|
Kernel-scope data (<kname> is replaced by corresponding kernel's name):
|
|
- <kname>_DynamicStateHeap.bin - initial DynamicStateHeap (binary file)
|
|
- <kname>_SurfaceStateHeap.bin - initial SurfaceStateHeap (binary file)
|
|
- <kname>_KernelHeap.asm - list of instructions describing
|
|
the kernel function (text file)
|
|
|
|
Usage: ocloc disasm -file <file> [-patch <patchtokens_dir>] [-dump <dump_dir>] [-device <device_type>] [-ignore_isa_padding]
|
|
-file <file> Input file to be disassembled.
|
|
This file should be an Intel Compute GPU device binary.
|
|
|
|
-patch <patchtokens_dir> Optional path to the directory containing
|
|
patchtoken definitions (patchlist.h, etc.)
|
|
as defined in intel-graphics-compiler (IGC) repo,
|
|
IGC subdirectory :
|
|
IGC/AdaptorOCL/ocl_igc_shared/executable_format
|
|
By default (when patchtokens_dir is not provided)
|
|
patchtokens won't be decoded.
|
|
|
|
-dump <dump_dir> Optional path for files representing decoded binary.
|
|
Default is './dump'.
|
|
|
|
-device <device_type> Optional target device of input binary
|
|
<device_type> can be: %s
|
|
By default ocloc will pick base device within
|
|
a generation - i.e. both skl and kbl will
|
|
fallback to skl. If specific product (e.g. kbl)
|
|
is needed, provide it as device_type.
|
|
|
|
-ignore_isa_padding Ignores Kernel Heap padding - Kernel Heap binary
|
|
will be saved without padding.
|
|
|
|
--help Print this usage message.
