This patch enables write IO to transfer data to backing device.
For that, it implements write_to_bdev function which creates
new bio and chaining with parent bio to make the parent bio

zram_decompress_page naming is not proper because it doesn't
decompress if page was dedup hit or stored with compression.
Use more abstract term and consistent with write path function

zRam is useful for memory saving with compressible pages but sometime,

With backing device, zram needs management of free space of

This patch adds bitmap logic to manage free space which is

This patch enables read IO from backing device. For the feature,

This patch adds region_id to fpga_image_info data structure, it
allows driver to pass region id information to fpga-mgr via
fpga_image_info for fpga reconfiguration function.

The Intel FPGA device appears as a PCIe device on the system. This patch
implements the basic framework of the driver for Intel PCIe device which
locates between CPU and Accelerated Function Units (AFUs).

For feature devices drivers, both the FPGA Management Engine (FME) and
Accelerated Function Unit (AFU) driver need to expose user interfaces via
the device file, for example, mmap and ioctls.
This patch adds chardev support in the pcie driver for feature devices,
FME and AFU

Device Feature List structure creates a link list of feature headers
within the MMIO space to provide an extensible way of adding features.
The Intel FPGA PCIe driver walks through the feature headers to enumerate
feature devices, FPGA Management Engine (FME) and FPGA Port f
This patch removes OF dependency of fpga-bridge, it allows drivers
to use fpga-bridge class without device tree support.

This patch abstracts the common operations of the sub features, and defines
the feature_ops data structure, including init, uinit and ioctl function
pointers. And this patch adds some common helper functions for FME and AFU
drivers, e.g feature_dev_use_begin/end which are use
This patch adds fpga manager driver for Intel FPGA Management

Partial Reconfiguration (PR) is the most important function for FME. It
allows reconfiguration for given Port/Accelerated Function Unit (AFU).
It creates platform devices for fpga-mgr, fpga-regions and fpga-bridges,
and invokes fpga-region's interface (fpga_region_program_fpga)
From: Kang Luwei
The FPGA Management Engine (FME) provides power, thermal management,
performance counters, partial reconfiguration and other functions. For each
function, it is packaged into a private feature linked to the FME feature
device in the 'Device Feature List'. It's a platform device c
For FPGA Management Engine (FME), it requires fpga_for_each_port callback
for actions on ports, so export this function from PCIe driver by adding
the callback to the platform data.

User Accelerated Function Unit sub feature exposes the MMIO region of

On Intel FPGA devices, the Accelerated Function Unit (AFU), can be
reprogrammed for different functions. It connects to the FPGA
infrastructure("blue bistream") via a Port. Port CSRs are implemented
separately from the AFU CSRs to provide control and status of the Port.
