Hi Greg / Moritz
This is v2 patchset which adds more features to FPGA DFL. This patchset
is made on top of patch[1] and char-misc-next tree. Documentation patch
for DFL is dropped from this patchset, and will resubmit it later to
avoid conflict.
Main changes from v1:
- remove DRV/MODULE_VERSION
This patch adds support for global error reporting for FPGA
Management Engine (FME), it introduces sysfs interfaces to
report different error detected by the hardware, and allow
user to clear errors or inject error for testing purpose.

In early partial reconfiguration private feature, it only
supports 32bit data width when writing data to hardware for
PR. 512bit data width PR support is an important optimization
for some specific solutions (e.g. XEON with FPGA integrated),
it allows driver to use AVX512 instruction to improve the
In order to support virtualization usage via PCIe SRIOV, this patch
adds two ioctls under FPGA Management Engine (FME) to release and
assign back the port device. In order to safely turn Port from PF
into VF and enable PCIe SRIOV, it requires user to invoke this
PORT_RELEASE ioctl to release port f
As these two functions are used by other private features. e.g.
in error reporting private feature, it requires to check port status
and reset port for error clearing.
