Hello,

This patch series adds management physical function driver for Xilinx Alveo PCIe
accelerator cards, https://www.xilinx.com/products/boards-and-kits/alveo.html
This driver is part of Xilinx Runtime (XRT) open source stack.

The patch depends on the "PATCH Xilinx Alveo libfdt prep" which was posted
before.

ALVEO PLATFORM ARCHITECTURE

Alveo PCIe FPGA based platforms have a static *shell* partition and a partial
re-configurable *user* partition. The shell partition is automatically loaded from
flash when host is booted and PCIe is enumerated by BIOS. Shell cannot be changed
till the next cold reboot. The shell exposes two PCIe physical functions:

1. management physical function
2. user physical function

The patch series includes Documentation/xrt.rst which describes Alveo
platform, xmgmt driver architecture and deployment model in more more detail.

Users compile their high level design in C/C++/OpenCL or RTL into FPGA image
using Vitis https://www.xilinx.com/products/design-tools/vitis/vitis-platform.html
tools. The image is packaged as xclbin and contains partial bitstream for the
user partition and necessary metadata. Users can dynamically swap the image
running on the user partition in order to switch between different workloads.

ALVEO DRIVERS

Alveo Linux kernel driver *xmgmt* binds to management physical function of
Alveo platform. The modular driver framework is organized into several
platform drivers which primarily handle the following functionality:

1.  Loading firmware container also called xsabin at driver attach time
2.  Loading of user compiled xclbin with FPGA Manager integration
3.  Clock scaling of image running on user partition
4.  In-band sensors: temp, voltage, power, etc.
5.  Device reset and rescan
6.  Flashing static *shell* partition

The platform drivers are packaged into *xrt-lib* helper module with a well
defined interfaces the details of which can be found in Documentation/xrt.rst.

xmgmt driver is second generation Alveo management driver and evolution of
the first generation (out of tree) Alveo management driver, xclmgmt. The
sources of the first generation drivers were posted on LKML last year--
https://lore.kernel.org/lkml/20190319215401.6562-1-sonal.santan@xilinx.com/

Changes since the first generation driver include the following: the driver
has been re-architected as data driven modular driver; the driver has been
split into xmgmt and xrt-lib; user physical function driver has been removed
from the patch series.

Alveo/XRT security and platform architecture is documented on the following 
GitHub pages:
https://xilinx.github.io/XRT/master/html/security.html
https://xilinx.github.io/XRT/master/html/platforms_partitions.html

User physical function driver is not included in this patch series.

TESTING AND VALIDATION

xmgmt driver can be tested with full XRT open source stack which includes
user space libraries, board utilities and (out of tree) first generation
user physical function driver xocl. XRT open source runtime stack is
available at https://github.com/Xilinx/XRT. This patch series has been
validated on Alveo U50 platform.

Complete documentation for XRT open source stack can be found here--
https://xilinx.github.io/XRT/master/html/index.html

Thanks,
-Sonal

I've not gotten into the patch details, but I'm not clear on what the
lifecycle of the DT looks like here. What's the starting point and
what manipulations to the DT are being done? I'm trying to understand
if using libfdt is the right way versus operating on an unflattened
tree.

The DT is created when *xmgmt* driver attaches to the device and reads the 
xsabin. The xsabin defines the shell and HW subsystems contained in the shell. 
Since the shell is live for the lifetime of the driver the DT is captured in the 
partition subdev. The partition then looks for "addressable_endpoints" node and 
walks the list of child end point nodes each of which is then copied into its own 
instance of subdev. The life cycle of the copied nodes is same as the owning subdev. 
All the DT nodes are released when the partition together with its child subdevs 
goes away which happens when the driver is unloaded.

xmgmt driver also collects all end points which advertise "pcie_physical_function 
= <0x01>" and then constructs a DT on the fly which is then sent to the user 
physical function driver via mailbox. This requires support for manipulating device 
tree nodes.

In the next revision of the driver we would like to add support for a variation of 
platform which has three partitions: base, shell and user-- 
https://xilinx.github.io/XRT/master/html/platforms_partitions.html#two-stage-platforms

In this model, *base* is initialized like described above. However *shell* can be 
changed dynamically by service provider. This means xmgmt would load DT 
corresponding to shell partition when shell is loaded and tear it down when shell 
is unloaded. The DT corresponding to *base* remains unaffected.

Thanks,

> This patch series adds management physical function driver for Xilinx Alveo PCIe
> accelerator cards, https://www.xilinx.com/products/boards-and-kits/alveo.html
> This driver is part of Xilinx Runtime (XRT) open source stack.
> 
> The patch depends on the "PATCH Xilinx Alveo libfdt prep" which was posted

> 
> ALVEO PLATFORM ARCHITECTURE
> 
> Alveo PCIe FPGA based platforms have a static *shell* partition and a partial
> re-configurable *user* partition. The shell partition is automatically loaded from
> flash when host is booted and PCIe is enumerated by BIOS. Shell cannot be changed
> till the next cold reboot. The shell exposes two PCIe physical functions:
> 
> 1. management physical function
> 2. user physical function
> 
> The patch series includes Documentation/xrt.rst which describes Alveo
> platform, xmgmt driver architecture and deployment model in more more detail.
> 
> Users compile their high level design in C/C++/OpenCL or RTL into FPGA image
> using Vitis https://www.xilinx.com/products/design-tools/vitis/vitis-platform.html
> tools. The image is packaged as xclbin and contains partial bitstream for the
> user partition and necessary metadata. Users can dynamically swap the image
> running on the user partition in order to switch between different workloads.
> 
> ALVEO DRIVERS
> 
> Alveo Linux kernel driver *xmgmt* binds to management physical function of
> Alveo platform. The modular driver framework is organized into several
> platform drivers which primarily handle the following functionality:
> 
> 1.  Loading firmware container also called xsabin at driver attach time
> 2.  Loading of user compiled xclbin with FPGA Manager integration
> 3.  Clock scaling of image running on user partition
> 4.  In-band sensors: temp, voltage, power, etc.
> 5.  Device reset and rescan
> 6.  Flashing static *shell* partition
> 
> The platform drivers are packaged into *xrt-lib* helper module with a well
> defined interfaces the details of which can be found in Documentation/xrt.rst.
> 
> xmgmt driver is second generation Alveo management driver and evolution of
> the first generation (out of tree) Alveo management driver, xclmgmt. The
> sources of the first generation drivers were posted on LKML last year--
> https://lore.kernel.org/lkml/20190319215401.6562-1-sonal.santan@xilinx.com/
> 
> Changes since the first generation driver include the following: the driver
> has been re-architected as data driven modular driver; the driver has been
> split into xmgmt and xrt-lib; user physical function driver has been removed
> from the patch series.

A few general things.

Use scripts/get_maintainer.pl to find who a patch should go to, i should have been on the cc line.

Each patch should at a minimum pass scripts/checkpatch.pl, none do.

Looking broadly at the files, there are competing names xrt or alveo.

It seems like xrt is the dfl equivalent, so maybe

drivers/fpga/alveo should be drivers/fpga/xrt

There are a lot of files with unnecessary prefixes

ex/

fpga/alveo/include/xrt-ucs.h could just be fpga/alveo/include/ucs.h

individual subdev's may not belong in the fpga subsystem.

I think it would be better to submit these one at a time as is done for dfl.

So this will not block getting the basics done, in the next revision, can you leave the subdev's out ?

 

Because of the checkpatch.pl failures, I will wait for the next revision.

Looks like a few files missed our checkpatch process. Will address in the
upcoming patch series.

Would work on separating xrt infrastructure and subdevs header files
into separate directories and drop the xrt prefix.

In the upcoming patch revision, will drop the subdevs except bare minimum 
necessary to perform bitstream download.
