Xilinx FPGA Resource Manager (XRM)

---

XRM - Xilinx FPGA Resource manager is the software to manage all the FPGA hardware on the system. All the Kernels (IP Kernel or Soft Kernel) on FPGA board are abstracted as one CU resource in XRM. XRM providers interface to allocate and release CU. The smallest allocation unit is channel, which is percentage of one CU. XRM providers command line tool (xrmadm) to download xclbin to device. During the download processing, XRM builds up the resource database. XRM daemon (xrmd) is running at background as core engine to support resource reservation, relinquish, allocation and release. The user APIs are defined in xrm.h header file.

xrm's Issues

How to use XRM through Vitis-AI

Through the understanding of XRM, I have a general understanding of how to specify xclbin for unused cards, but I want to use Vitis-AI application on different cards, how do I need to implement? Is there a flow about this situation?
Thanks!

Please help me when i run build.sh

Killing xrmd process and creating second encoder session breakes the first one.

Hello,
I have encountered the following problem:

1. Create first encoder session
2. kill xrmd process: kill -9
3. Create second encoder session

Until step 3 first session continue to work. After that xma_enc_session_send_frame in the first session starts to fail with the following error messages:

xma-vcu-encoder Error: (get_raw_host_frame) Buffer Pool full - no free buffer available
xma-vcu-encoder xma_encoder_send_frame: ERROR: host buffer write failed

There is no such problem if no xrmd killing is performed. Two session and running without error simultaneously.

OS info:
lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: OracleServer
Description: Oracle Linux Server release 7.9
Release: 7.9
Codename: n/a

It is Amazon EC2 VT1 instance.

unit xrmd.service could not be found

This erro occured when I run the test command to start XRMD. My OS is Ubuntu 18.04. Thanks for your replys.

XRM API functions can fail when reading from socket fails with EINTR

In rare circumstances ctx->socket->read_some in xrmJsonRequest can fail with EINTR aka boost::asio::error::interrupted.
Instead of continuing reading XRM fails an API function.
