+
+# What's New in This Release 
+
+## HIP Enhancements
+
+The ROCm v4.5 release consists of the following HIP enhancements:
+
+### HIP Direct Dispatch
+
+The conventional producer-consumer model where the host thread(producer) enqueues commands to a command queue (per stream), which is then
+processed by a separate, per-stream worker thread (consumer) created by the runtime, is no longer applicable.
+
+In this release, for Direct Dispatch, the runtime directly queues a packet to the AQL queue (user mode queue to GPU) in Dispatch and some of
+the synchronization. This new functionality indicates the total latency of the HIP Dispatch API and the latency to launch the first wave on the
+GPU.
+
+In addition, eliminating the threads in runtime has reduced the variance in the dispatch numbers as the thread scheduling delays and
+atomics/locks synchronization latencies are reduced.
+
+This feature can be disabled by setting the following environment variable,
+
+```     
+     AMD_DIRECT_DISPATCH=0
+
+```
+
+### Support for HIP Graph 
+
+ROCm v4.5 extends support for HIP Graph. For details, refer to the HIP
+API Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD-HIP-API-4.5.pdf
+
+### Enhanced *launch_bounds* Check Error Log Message 
+
+When a kernel is launched with HIP APIs, for example, hipModuleLaunchKernel(), HIP validates to check that input kernel
+dimension size is not larger than specified launch_bounds.
+
+If exceeded, HIP returns launch failure if AMD_LOG_LEVEL is set with the proper value. Users can find more information in the error log message,
+including launch parameters of kernel dim size, launch bounds, and the name of the faulting kernel. It is helpful to figure out the faulting
+kernel. Besides, the kernel dim size and launch bounds values will also assist in debugging such failures.
+
+For more details, refer to the HIP Programming Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD_HIP_Programming_Guide.pdf
+
+
+### HIP Runtime Compilation
+
+HIP now supports runtime compilation (hipRTC), the usage of which will provide the possibility of optimizations and performance improvement
+compared with other APIs via regular offline static compilation. 
+
+hipRTC APIs accept HIP source files in character string format as input parameters and create handles of programs by compiling the HIP source
+files without spawning separate processes.
+
+For more details on hipRTC APIs, refer to the HIP API Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD-HIP-API-4.5.pdf
+
+### New Flag for Backwards Compatibility on float/double atomicAdd Function
+
+In the ROCm4.5 release, a new compilation flag is introduced as an
+option in the CMAKE file. This flag ensures backwards compatibility in
+float/double atomicAdd functions.
+
+```   
+     \_\_HIP_USE_CMPXCHG_FOR_FP_ATOMICS
+```   
+
+This compilation flag is not set("0") by default, so the HIP runtime uses the current float/double atomicAdd functions.
+
+If this compilation flag is set to "1" with the CMAKE option, the existing float/double atomicAdd functions is used for compatibility with
+compilers that do not support floating point atomics.
+
+```  
+     D\_\_HIP_USE_CMPXCHG_FOR_FP_ATOMICS=1
+```  
+For details on how to build the HIP runtime, refer to the HIP Programming Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD_HIP_Programming_Guide.pdf
+
+
+
+### Updated HIP Version Definition
+
+The HIP version definition is updated as follows:
+
+```  
+     HIP_VERSION=HIP_VERSION_MAJOR \* 10000000 + HIP_VERSION_MINOR \*
+     100000 + HIP_VERSION_PATCH)
+```  
+
+The HIP version can be queried from the following HIP API call,
+
+```  
+     hipRuntimeGetVersion(&runtimeVersion);
+```  
+
+The version returned is always greater than the versions in the previous
+ROCm releases.
+
+**Note:** The version definition of the HIP runtime is different from that of CUDA. The function returns the HIP runtime version on the AMD
+platform, while on the NVIDIA platform, it returns the CUDA runtime version. There is no mapping or a correlation between the HIP and CUDA
+versions.
+
+
+
+### Planned HIP Enhancements and Fixes
+
+#### Changes to hiprtc implementation to match nvrtc behavior
+
+In this release, there are changes to the *hiprtc* implementation to
+match the *nvrtc* behavior.
+
+**Impact:** Applications can no longer explicitly include HIP runtime header files. Minor code changes are required to remove the HIP runtime
+header files.
+
+#### HIP device attribute enumeration
+
+In a future release, there will be a breaking change in the HIP device attribute enumeration. Enum values are being rearranged to accommodate
+future enhancements and additions.
+
+**Impact:** This will require users to rebuild their applications. No code changes are required.
+
+#### Changes to behavior of hipGetLastError() and hipPeekAtLastError() to match CUDA behavior available
+
+In a later release, changes to behavior of hipGetLastError() and hipPeekAtLastError() to match CUDA behavior will be available.
+
+**Impact:** Applications relying on the previous behavior will be impacted and may require some code changes.
+
+## Unified Memory Support in ROCm
+
+Unified memory allows applications to map and migrate data between CPU and GPU seamlessly without explicitly copying it between different
+allocations. This enables a more complete implementation of *hipMallocManaged*, *hipMemAdvise*, *hipMemPrefetchAsync* and related
+APIs. Without unified memory, these APIs only support system memory. With unified memory, the driver can automatically migrate such memory to
+GPU memory for faster access.
+
+### Supported Operating Systems and Versions
+
+This feature is only supported on recent Linux kernels. Currently, it works on Ubuntu versions with 5.6 or newer kernels and the DKMS driver
+from ROCm. Current releases of RHEL and SLES do not support this feature yet. Future releases of those distributions will add support for this.
+The unified memory feature is also supported in the KFD driver included with upstream kernels starting from Linux 5.14.
+
+Unified memory only works on GFXv9 and later GPUs, including Vega10 and MI100. Fiji, Polaris and older GPUs are not supported. To check whether
+unified memory is enabled, look in the kernel log for this message:
+
+```  
+     \$ dmesg \| grep \"HMM registered"
+```  
+
+If unified memory is enabled, there should be a message like "HMM registered xyzMB device memory". If unified memory is not supported on
+your GPU or kernel version, this message is missing.
+
+### Unified Memory Support and XNACK
+
+Unified memory support comes in two flavours, XNACK-enabled and XNACK-disabled. XNACK refers to the ability of the GPU to handle page
+faults gracefully and retry a memory access. In XNACK-enabled mode, the GPU can handle retry after page-faults, which enables mapping and
+migrating data on demand, as well as memory overcommitment. In XNACK-disabled mode, all memory must be resident and mapped in the GPU
+page tables when the GPU is executing application code. Any migrations involve temporary preemption of the GPU queues by the driver. Both page
+fault handling and preemptions, happen automatically and are transparent to the applications.
+
+XNACK-enabled mode only has experimental support. XNACK-enabled mode requires compiling shader code differently. By default, the ROCm
+compiler builds code that works in both modes. Code can be optimized for one specific mode with compiler options:
+
+OpenCL:
+
+```  
+     clang \... -mcpu=gfx908:***xnack+***:sramecc- \... // xnack on, sramecc off\
+     clang \... -mcpu=gfx908:***xnack-***:sramecc+ \... // xnack off, sramecc on
+```  
+
+HIP:
+```  
+     clang \... \--cuda-gpu-arch=gfx906:xnack+ \... // xnack on\
+     clang \... \--cuda-gpu-arch=gfx906:xnack- \... // xnack off
+```  
+Not all the math libraries included in ROCm support XNACK-enabled mode on current hardware. Applications will fail to run if their shaders are
+compiled in the incorrect mode.
+
+On current hardware, the XNACK mode can be chosen at boot-time by a module parameter amdgpu.noretry. The default is XNACK-disabled
+(amdgpu.noretry=1).
+
+## System Management Interface 
+
+### Enhanced ROCm SMI --setpoweroverdrive Functionality
+
+The ROCm System Management Interface (SMI) *--setpoweroverdrive* functionality is used to lower the power cap on a device without needing
+to enable the OverDrive functionality in the driver. Similarly, even with the OverDrive driver functionality enabled, it is possible to
+request a lower power cap than the card's default.
+
+Currently, any use of the *--setpoweroverdrive* functionality in rocm-smi prints an out-of-spec warning to the screen and requires the
+user to agree that using this functionality potentially voids their warranty. However, this warning should only be printed when users are
+trying to set the power cap to higher than the card's default, which requires the OverDrive driver functionality to be enabled.
+
+For example:
+
+The default power cap is 225.0W before any changes.
+
+```
+
+     \[atitest\@rhel85 smi\]\$ ./rocm_smi.py --resetpoweroverdrive
+     ======================= ROCm System Management Interface =======================
+
+     ========================== Reset GPU Power OverDrive ===========================
+
+     GPU\[0\] : Successfully reset Power OverDrive to: 225W
+     ============================ End of ROCm SMI Log ============================
+
+     Now, after using --setpoweroverdrive to lower the power cap to 123
+     watts:
+
+     \[atitest\@rhel85 smi\]\$ ./rocm_smi.py --setpoweroverdrive 123
+     ======================= ROCm System Management Interface =======================
+
+     =========================== Set GPU Power OverDrive ============================
+
+     GPU\[0\] : Successfully set power to: 123W
+     ======================= End of ROCm SMI Log ==============================
+
+     Setting a power cap lower than the default of 225.0W (in this case,
+     123W) does not give a warning.
+
+     To verify that the power is set to the correct value:
+
+     \[atitest\@rhel85 smi\]\$ ./rocm_smi.py --showmaxpower
+     ======================= ROCm System Management Interface =======================
+
+     ======================== Power Cap ===================================
+
+     GPU\[0\] : Max Graphics Package Power (W): 123.0
+     ========================End of ROCm SMI Log ==============================
+```
+
+
+## OpenMP Enhancements
+
+The ROCm installation includes an LLVM-based implementation, which fully
+supports OpenMP 4.5 standard and a subset of the OpenMP 5.0 standard.
+Fortran and C/C++ compilers and corresponding runtime libraries are
+included. Along with host APIs, the OpenMP compilers support offloading
+code and data onto GPU devices.

+# Known Issues in This Release 
+
+The following are the known issues in this release.
+
+## clinfo and rocminfo Do Not Display Marketing Name
+
+clinfo and rocminfo display a blank field for Marketing Name. 
+
+This is due to a missing package that is not yet available from ROCm. This package will be distributed in future ROCm releases.
+
+## Compiler Support for Function Pointers and Virtual Functions
+
+A known issue in the compiler support for function pointers and virtual functions on the GPU may cause undefined behavior due to register
+corruption. 
+
+A temporary workaround is to compile the affected application with this option:
+
+```
+     -mllvm -amdgpu-fixed-function-abi=1
      
+ ```
 
-## rocProf Command Line Tool Python Requirement
-SQLite3 is a required Python module for the rocprof command-line tool.  You can install the SQLite3 Python module using the pip utility and set env var ROCP_PYTHON_VERSION to the Python version, which includes the SQLite3 module.
+**Note:** This is an internal compiler flag and may be removed without notice once the issue is addressed in a future release.
 
 
+## Debugger Process Exit May Cause ROCgdb Internal Error
 
-## Heterogeneous-Compute Interface for Portability
-
-In this release, the Heterogeneous Compute Compiler (HCC) compiler is deprecated and the HIP-Clang compiler is introduced for compiling Heterogeneous-Compute Interface for Portability (HIP) programs.
-
-NOTE: The HCC environment variables will be gradually deprecated in subsequent releases.
-
-The majority of the codebase for the HIP-Clang compiler has been upstreamed to the Clang trunk. The HIP-Clang implementation has undergone a strict code review by the LLVM/Clang community and comprehensive tests consisting of LLVM/Clang build bots. These reviews and tests resulted in higher productivity, code quality, and lower cost of maintenance.
-
-![ScreenShot](HIPClang2.png)
-
-For most HIP applications, the transition from HCC to HIP-Clang is transparent and efficient as the HIPCC and HIP cmake files automatically choose compilation options for HIP-Clang and hide the difference between the HCC and HIP-Clang code. However, minor changes may be required as HIP-Clang has a stricter syntax and semantic checks compared to HCC.
-
-NOTE: Native HCC language features are no longer supported.
-
-## Radeon Open Compute Common Language Runtime
-In this release,  the HIP runtime API is implemented on top of Radeon Open Compute Common Language Runtime (ROCclr). ROCclr is an abstraction layer that provides the ability to interact with different runtime backends such as ROCr.
-
-## OpenCL Runtime
-The following OpenCL runtime changes are made in this release:
-
-* AMD ROCm OpenCL Runtime extends support to OpenCL2.2
-* The developer branch is changed from master to master-next
-
-## AMD ROCm GNU Debugger (ROCgdb)
-The AMD ROCm Debugger (ROCgdb) is the AMD ROCm source-level debugger for Linux based on the GNU Debugger (GDB). It enables heterogeneous debugging on the AMD ROCm platform of an x86-based host architecture along with AMD GPU architectures and supported by the AMD Debugger API Library (ROCdbgapi).
-
-The AMD ROCm Debugger is installed by the rocm-gdb package. The rocm-gdb package is part of the rocm-dev meta-package, which is in the rocm-dkms package.
-
-The current AMD ROCm Debugger (ROCgdb) is an initial prototype that focuses on source line debugging. Note, symbolic variable debugging capabilities are not currently supported.
-
-You can use the standard GDB commands for both CPU and GPU code debugging. For more information about ROCgdb, refer to the ROCgdb User Guide, which is installed at:
-
-* /opt/rocm/share/info/gdb.info as a texinfo file
-* /opt/rocm/share/doc/gdb/gdb.pdf as a PDF file
-
-The AMD ROCm Debugger User Guide is available as a PDF at:
-
-https://github.com/RadeonOpenCompute/ROCm/blob/master/gdb.pdf
+If the debugger process exits during debugging, ROCgdb may report internal errors. This issue occurs as it attempts to access the AMD GPU
+state for the exited process. To recover, users must restart ROCgdb.
  
-For more information about GNU Debugger (GDB), refer to the GNU Debugger (GDB) web site at: http://www.gnu.org/software/gdb
+As a workaround, users can set breakpoints to prevent the debugged process from exiting. For example, users can set breakpoints at the last
+statement of the main function and in the abort() and exit() functions. This temporary solution allows the application to be re-run without
+restarting ROCgdb.
 
+This issue is currently under investigation and will be fixed in a future release.
 
-## AMD ROCm Debugger API Library 
+For more information, refer to the ROCgdb User Guide at,
 
-The AMD ROCm Debugger API Library (ROCdbgapi) implements an AMD GPU debugger application programming interface (API) that provides the support necessary for a client of the library to control the execution and inspect the state of AMD GPU devices.
+https://github.com/RadeonOpenCompute/ROCm/blob/master/ROCDebugger_User_Guide.pdf
 
-The following AMD GPU architectures are supported:
-* Vega 10 
-* Vega 7nm
+## Cache Issues with ROCProfiler
 
-The AMD ROCm Debugger API Library is installed by the rocm-dbgapi package. The rocm-gdb package is part of the rocm-dev meta-package, which is in the rocm-dkms package.
-The AMD ROCm Debugger API Specification is available as a PDF at:
+When the same kernel is launched back-to-back multiple times on a GPU, a cache flush is executed each time the kernel finishes when profiler data is collected. The cache flush is inserted by ROCprofiler for each kernel. This prevents kernel from being cached, instead it is being read each time it is launched. As a result the cache hit rate from rocprofiler is reported as 0% or very low.
 
-https://github.com/RadeonOpenCompute/ROCm/blob/master/amd-dbgapi.pdf
+This issue is under investigation and will be fixed in a future release. 
 
-## rocProfiler Dispatch Callbacks Start Stop API
+## Stability Issue on LAMMPS-KOKKOS Applications
 
-In this release, a new rocprofiler start/stop API is added to enable/disable GPU kernel HSA dispatch callbacks. The callback can be registered with the 'rocprofiler_set_hsa_callbacks' API. The API helps you eliminate some profiling performance impact by invoking the profiler only for kernel dispatches of interest. This optimization will result in significant performance gains.
+On mGPU machines, lammps-kokkos applications experience a stability issue (AMD Instinct MI100™). 
 
-The API provides the following functions:
-* *hsa_status_t rocprofiler_start_queue_callbacks();* is used to start profiling
-* *hsa_status_t rocprofiler_stop_queue_callbacks();* is used to stop profiling. 
+As a workaround, perform a Translation LookAside Buffer (TLB) flush. 
 
-For more information on kernel dispatches, see the HSA Platform System Architecture Specification guide at http://www.hsafoundation.com/standards/.
+The issue is under active investigation and will be resolved in a future release.
 
-## ROCm Communications Collective Library 
-The ROCm Communications Collective Library (RCCL) consists of the following enhancements:
-* Re-enable target 0x803
-* Build time improvements for the HIP-Clang compiler
 
-### NVIDIA Communications Collective Library Version Compatibility
-AMD RCCL is now compatible with NVIDIA Communications Collective Library (NCCL) v2.6.4 and provides the following features: 
-* Network interface improvements with API v3
-* Network topology detection 
-* Improved CPU type detection
-* Infiniband adaptive routing support
 
-## MIOpen Optional Kernel Package Installation
-MIOpen provides an optional pre-compiled kernel package to reduce startup latency. 
+# Deprecations
 
-NOTE: The installation of this package is optional. MIOpen will continue to function as expected even if you choose to not install the pre-compiled kernel package. This is because MIOpen compiles the kernels on the target machine once the kernel is run. However, the compilation step may significantly increase the startup time for different operations.
+## AMD Instinct MI25 End of Life
 
-To install the kernel package for your GPU architecture, use the following command:
+ROCm release v4.5 is the final release to support AMD Instinct MI25. AMD Instinct MI25 has reached End of Life (EOL). ROCm 4.5 represents the
+last certified release for software and driver support. AMD will continue to provide technical support and issue resolution for AMD
+Instinct MI25 on ROCm v4.5 for a period of 12 months from the software GA date. 
 
-*apt-get install miopen-kernels-<arch>-<num cu>*
- 
-* <arch> is the GPU architecture. For example, gfx900, gfx906
-* <num cu> is the number of CUs available in the GPU. For example, 56 or 64 
- 
+## Planned Deprecation for Code Object Versions 2 and 3 
 
-## New SMI Event Interface and Library
+With the ROCm v4.5 release, the generation of code object versions 2 and 3 is being deprecated and may be removed in a future release. This deprecation notice does not impact support for the execution of AMD GPU code object versions.
 
-A Systems Management Interface (SMI) event interface is added to the kernel and ROCm SMI  lib for system administrators to get notified when specific events occur. On the kernel side, AMDKFD_IOC_SMI_EVENTS input/output control is enhanced to allow notifications propagation to user mode through the event channel. 
+The -mcode-object-version Clang option can be used to instruct the compiler to generate a specific AMD GPU code object version. In ROCm v4.5, the compiler can generate AMD GPU code object version 2, 3, and 4, with version 4 being the default if not specified. 
 
-On the ROCm SMI lib side, APIs are added to set an event mask and receive event notifications with a timeout option. Further, ROCm SMI API details can be found in the PDF generated by Doxygen from source or by referring to the rocm_smi.h header file (see the rsmi_event_notification_* functions).
 
-For the more details about ROCm SMI API, see

+# Deploying ROCm
 
-## API for CPU Affinity
-A new API is introduced for aiding applications to select the appropriate memory node for a given accelerator(GPU). 
-
-The API for CPU affinity has the following signature:
-
-*rsmi_status_t rsmi_topo_numa_affinity_get(uint32_t dv_ind, uint32_t *numa_node);*
-
-This API takes as input, device index (dv_ind), and returns the NUMA node (CPU affinity), stored at the location pointed by numa_node pointer, associated with the device.
-
-Non-Uniform Memory Access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. 
-
-## Radeon Performance Primitives Library
-The new Radeon Performance Primitives (RPP) library is a comprehensive high-performance computer vision library for AMD (CPU and GPU) with the HIP and OpenCL backend. The target operating system is Linux.
-
-![ScreenShot](RPP.png)
-
-For more information about prerequisites and library functions, see 
-
-https://github.com/GPUOpen-ProfessionalCompute-Libraries/MIVisionX/tree/master/docs
-
-# Fixed Issues
-
-## Device printf Support for HIP-Clang
-HIP now supports the use of printf in the device code. The parameters and return value for the device-side printf follow the POSIX.1 standard, with the exception that the "%n" specifier is not supported. A call to printf blocks the calling wavefront until the operation is completely processed by the host. 
-
-No host-side runtime calls by the application are needed to cause the output to appear. There is also no limit on the number of device-side calls to printf or the amount of data that is printed.
-
-For more details, refer the HIP Programming Guide at:
-https://rocmdocs.amd.com/en/latest/Programming_Guides/HIP-GUIDE.html#hip-guide
-
-## Assertions in HIP Device Code  
-Previously, a failing assertion caused early termination of kernels and the application to exit with a line number, file, and failing condition printed to the screen.
-This issue is now fixed and the assert() and abort() functions are implemented for HIP device code. 
-NOTE: There may be a performance impact in the use of device assertions in its current form. 
-
-You may choose to disable the assertion in the production code. For example, to disable an assertion of:
-
-*assert(foo != 0);*    
-
-you may comment it out as:  
-
-*//assert(foo != 0);*
-
-NOTE: Assertions are currently enabled by default. 
-
-# Known Issues 
-The following are the known issues in the v3.5 release.
-
-## HIPify-Clang Installation Failure on CentOS/RHEL 
-
-HIPify-Clang fails to install on CentOS/RHEL with the following error:
-
-*file from install of hipify-clang conflicts with file from package hip-base*
-
-**Workaround**: This is a known issue and the following workaround is recommended for a successful installation of HIPify-Clang on CentOS/RHEL:
-
-* Download HIPify-Clang RPM. For example, *hipify-clang-11.0.0.x86_64.rpm*
-* Perform a force install using the following command: 
-
-  *sudo rpm -ivh --force hipify-clang-11.0.0.x86_64.rpm*
-
-
-## Failure to Process Breakpoint before Queue Destroy Results in ROCm Debugger Error
-When ROCgdb is in non-stop mode with an application that rapidly creates and destroys queues, a breakpoint may be reported that is not processed by the debugger before the queue is deleted. In some cases, this can result in the following error that prevents further debugging:
-
-*[amd-dbgapi]: fatal error: kfd_queue_id 2 should have been reported as a NEW_QUEUE before next_pending_event failed (rc=-2)*
-
-There are no known workarounds at this time.
-
-## Failure to Process Breakpoint before Queue Destroy Results in ROCm Debugger API Error
-
-When the ROCdbgapi library is used with an application that rapidly creates and destroys queues, a breakpoint may be reported that is not processed by the client before the queue is deleted. In some cases, this can result in a fatal error and the following error log message is produced:
-
-*[amd-dbgapi]: fatal error: kfd_queue_id 2 should have been reported as a NEW_QUEUE before next_pending_event failed (rc=-2)*

+* AMD "Carrizo" and "Bristol Ridge" APUs are enabled to run OpenCL, but do not yet support HIP or our libraries built on top of these compilers and runtimes.
   * As of ROCm 2.1, "Carrizo" and "Bristol Ridge" require the use of upstream kernel drivers.
   * In addition, various "Carrizo" and "Bristol Ridge" platforms may not work due to OEM and ODM choices when it comes to key configurations parameters such as inclusion of the required CRAT tables and IOMMU configuration parameters in the system BIOS.
   * Before purchasing such a system for ROCm, please verify that the BIOS provides an option for enabling IOMMUv2 and that the system BIOS properly exposes the correct CRAT table. Inquire with your vendor about the latter.

+* "Tonga", "Iceland", "Vega M", and "Vega 12" GPUs are not supported.
 * We do not support GFX8-class GPUs (Fiji, Polaris, etc.) on CPUs that do not have PCIe 3.0 with PCIe atomics.
   * As such, we do not support AMD Carrizo and Kaveri APUs as hosts for such GPUs.
   * Thunderbolt 1 and 2 enabled GPUs are not supported by GFX8 GPUs on ROCm. Thunderbolt 1 & 2 are based on PCIe 2.0.
 
+In the default ROCm configuration, GFX8 and GFX9 GPUs require PCI Express 3.0 with PCIe atomics. The ROCm platform leverages these advanced capabilities to allow features such as user-level submission of work from the host to the GPU. This includes PCIe atomic Fetch and Add, Compare and Swap, Unconditional Swap, and AtomicOp Completion.
