[PATCH v2 00/11] FPGA DFL updates

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

[PATCH v2 01/11] fpga: dfl: fme: support 512bit data width PR

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

[PATCH v2 02/11] fpga: dfl: fme: add DFL_FPGA_FME_PORT_RELEASE/ASSIGN ioctl support.

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
