SWDEV-198863 - Options for hip-clang-vdi path to provide the chicken bits, or functional equivalents to HCC_DB (phase 2)
Enable the log functions for release build.
Tests:
1. Linux HIP ROCM platform. VEGA10. Driver is release build.
1.1 export LOG_LEVEL=3
./hipModule
There are many logs.
1.2 export GPU_LOG_MASK=0
./hipModule
There is no log
2. Windows HIP PAL platform. VEGA10, Driver is release or fastdbg build.
2.1 set LOG_LEVEL=3
run test hipPrintfKernel
There are many logs
2.2 set GPU_LOG_MASK=0
run test hipPrintfKernel
There is no log

SWDEV-198863 - Options for hip-clang-vdi path to provide the chicken bits, or functional equivalents to HCC_DB (phase 1)
1. The log macros is turned off for release build. So log functions has zero impact to release build.
2. The log macros have level, mask, condition control. So we can have more control to avoid log flooding.
I also adjusted some existing log to use new log functions.
1. To excercise and test the new log functions.
2. To improve performance slightly.
3. The change is mainly for HIP-ROCM, we can move more in next phases for PAL or ORCA.
4. I make these log feature unavailable for release build. We can revert to old log functions for release build in a case by case method.
Tests:
1. http://ocltc.amd.com:8111/viewModification.html?modId=128289&personal=true&tab=vcsModificationBuildshttp://ocltc.amd.com:8111/viewModification.html?modId=128358&personal=true&tab=vcsModificationBuilds
2. release build, run hip program, there is no log
3. fastdebug build, run hip program,
export LOG_LEVEL=3
export GPU_LOG_MASK=4294967295
There was a lot of logs.
4. fastdebug build, run hip program,
export LOG_LEVEL=2
export GPU_LOG_MASK=4294967295
There was no logs.
5. fastdebug build, run hip program,
export LOG_LEVEL=3
export GPU_LOG_MASK=4294967294
There was much less logs.
6. fastdebug build, run hip program,
export LOG_LEVEL=3
export GPU_LOG_MASK=47102
There was even much less logs. The logs was expected according to the mask.
7. Tested step 2 to 6 similarily in Windows and Linux

SWDEV-198862 - Options for hip-clang-vdi path to provide the chicken bits, or functional equivalents to HCC_OPT_FLUSH
Add HCC_OPT_FLUSH flag to use fence scope agent when possible for HIP VDI. The flag is defaulted to turn on, similiar to HIP HCC.
Add AMD_OCL_OPT_FLUSH to use fence scope agent when possible for OpenCL. This was tested in Windows and PAL. Default is off.
This flag can be used for future OpenCL test.
Tests:
1. http://ocltc.amd.com:8111/viewModification.html?modId=127189&personal=true&tab=vcsModificationBuilds
The teamcity test includes HIP - VDI - Rocm tests.
2. VEGA10 , Windows, HIP, 110 hiptests PASS.
3. VEGA10 , Linux AMDGPU PRO, HIP - PAL, 110 hiptests PASS.

SWDEV-192384 - [HIP CQE][HIPonPAL][19.40] hipBindTexRef1DFetch, hipTextureRef2D are failed on all ASICs for both Win/Lnx
The runtime cannot trivially determine all the resources that will be used by a kernel, thus it can fail to make all of them resident.
1. Add new runtime flag PAL_ALWAYS_RESIDENT. Enabling this setting will cause resources to become resident at allocation time.
2. Set the default value of the above flag to true for HIP and false for OCL.

SWDEV-132899 - [OCL][GFX10] report number of WGP by default on gfx10 ASICs
Both HSAIL/SC and LC compilers use WGP mode by default on gfx10 ASICs (i.e., COMPUTE_PGM_RSRC1.WGP_MODE is set to 1 by both compilers) therefore runtime should report number of WGP (i.e., CU/2) on gfx10 ASICs by default.
The new environment variable (GPU_ENABLE_WGP_MODE = 0) can be used to force CU mode on LC (i.e., -mcumode option) if its needed (HSAIL/SC doesn't have any compiler option for forcing the CU mode)
Also, using the new environment variable (GPU_ENABLE_WAVE32_MODE) to control the wave32 mode on gfx10+.

Motivation: During testing ocltst on Windows on PAL/HSAIL/SC path on gfx10 HW emulator, it was found that SC uses WaveSize64 by default for compute kernels.
SC also has an interface that can be used for forcing the WaveSize to 32 or 64.
- Adding the "-force-wave-size-32" into compiler to be passed down to Finalizer/SC
- Adding environment variable "GPU_FORCE_WAVE_SIZE_32" that can be used from runtime to force WaveSize32 compilation in HSAIL/SC path
