* [Bugfix] [VTA] VTA DRAM Have A Logic Issue May Cause GEMM Output Wrong.
Symptom:
after change “LOG_BLOCK_IN” and “LOG_BLOCK_OUT” from vta_config.json
into 7, run vta "Simple Matrix Multiply" in "simulator", the vta
calculate result for GEMM is wrong.
Sometime VTA crash with error “Check failed: phy_addr != 0 (0 vs. 0) :
trying to get address that is nullptr”
Analysis:
Simulator hardcode kPageSize into 1<<12 and physical address calculate
based on this size, when doing “insn->dram_base” calculation , because
GetElemBytes(dst_memory_type) larger than page size, different physcial
address may get same dram_base, than caused logic issue and finally
trigger GEMM out put is wrong.
Solution:
add logic to check if PAGE SIZE larger then "GetElemBytes" return value.
* address review comments.
* [Bugfix][VTA] PkgConfig cause crash in PYNQ board due to link library
not exist.
Symptom:
When run vta_get_started.py with pynq board, host crash and
complain "cannot find -lsds_lib" and "cannot find -l:libdma.so"
Reproduce:
At pynq board, delete the ./build/vta_config.json, then run rpc
server.
In host machine run vta_get_started.py, issue would reproduce.
Analysis:
This issue caused by 'PkgConfig' function still using pynq2.1
library which not exist in pynq2.4 anymore, when a "reconfig_runtime"
logic of rpc_server.py get triggered , the compile would failed due to
link library not exist.
Solution:
change the link library to libcma.so.
* [Document Change][VTA] Change pynq version from 2.3 into 2.4.
Issue:
pynq 2.3 image not available anymore from pynq download page and pynq
2.4 is the current latest image which available in the said website, after
verification, currently VTA work good with pynq 2.4 image, hence update
related document from pynq 2.3 to 2.4.
Issue:
Once change LOG_BLOCK_IN or LOG_BLOCK_OUT into > 4 value, when run vta
“Simple Matrix Multiply” or load vta, vta would crash at vta_conv2d.py.
Analysis:
This issue caused by resnet18 logic of vta_conv2d.py which have
in_filter minmum size that is 16. > 4 value would cause such in_filter
check failed then make xfer_size be empty and find_schedules function
return a empty list finally cause crash.
Solution:
add the empty list check.
Issue:
One of existing illegal dependency check's condition always true,
the correct logic actually should be such check for store and load.
Solution:
Fix the said logic issue.
