* libhsakmt: Update hsakmt_fmm_get_handle to support address range Currently, hsakmt_fmm_get_handle works only if the address is allocated (staring) value. Update it so it can find the handle if address falls in the valid allocated range. This is useful for AMD infinity storage feature where data needs to be transferred to any memory within in the allocated range Signed-off-by: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com> * libhsakmt: Introduce AMD Infinity Storage (AIS) API Add hsaKmtAisReadWriteFile() API to support AMD Infinity Storage. The API moves data directly from GPU VRAM to a file. v2: Add in/out ioctl arguments to provide more status information to user space. Modify hsaKmt API also accordingly. Signed-off-by: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com> * rocr: Initial implementation of AMD Infinity Storage (AIS) Implement first two API: hsa_amd_ais_file_write and hsa_amd_ais_file_read v2: Change API from hsa_amd_ to hsa_amd_ais_ Change API to take in handle instead of fd for compatibility accross different platforms Original Author: Chris Freehill <Chris.Freehill@amd.com> Signed-off-by: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com> --------- Signed-off-by: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com>
ROCt Library
This repository includes the user-mode API interfaces used to interact with the ROCk driver.
Starting at 1.7 release, ROCt uses drm render device. This requires the user to belong to video group. Add the user account to video group with "sudo usermod -a -G video username" command if the user if not part of video group yet. NOTE: Users of Ubuntu 20.04 will need to add the user to the new "render" group, as Ubuntu has changed the owner:group of /dev/kfd to render:render as of that release
ROCk Driver
The ROCt library is not a standalone product and requires that you have the correct ROCk driver installed, or are using a compatible upstream kernel. Please refer to https://rocm.docs.amd.com under "Getting Started Guide" for a list of supported Operating Systems and kernel versions, as well as supported hardware.
Building the Thunk
A simple cmake-based system is available for building thunk. To build the thunk from the the ROCT-Thunk-Interface directory, execute:
mkdir -p build
cd build
cmake ..
make
If the hsakmt-roct and hsakmt-roct-dev packages are desired:
mkdir -p build
cd build
cmake ..
make package
If you choose not to build and install packages, manual installation of the binaries and header files can be done via:
make install
NOTE: For older versions of the thunk where hsakmt-dev.txt is present, "make package-dev" and "make install-dev" are required to generate/install the developer packages. Currently, these are created via the "make package" and "make install" commands
