Details

Piglet.ko loads a Bitfile into the FPGA, then runs and maintains it.
It provides the Piglet device and an EMIF interface to a virtual USB-Host controller.

This module is only used on AR7 models. I is enabled by CONFIG_PIGLET (Kernel 2.4) or CONFIG_AVM_PIGLET (Kernel 2.6).

The same job without EMIF interface but DECT support is performed by the Piglet_noemif.ko module.

Example from a 7150 with USB-Host in FPGA:

root@fritz31:/var/mod/root# grep emif /proc/iomem

be000000-be000068 : piglet_emifreg

Examples

From rc.S of a 7150 fw 4.72:

piglet_bitfile=microvoip_top.bit${HWRevision_BitFileCount}

piglet_load_params="\
  piglet_width_running=1 \
  piglet_usb_power_bit=-1 \
  piglet_disable_test=1 \
  piglet_cs=5 \
  piglet_reset_bit=-2 \
  piglet_bitfile_offset=0 \
  piglet_bitfile_write=-1 \
  piglet_bitfile_revbytes=1 \
  piglet_irq_gpio=18 \
  piglet_irq=9 \
"
modprobe Piglet piglet_bitfile=$piglet_bitfile $piglet_load_params

Parameters

Daily updated index of all parameters for this module found scanning Firmware-Probes. Last update: 2024-04-19 07:32 GMT.
These parameters can be passed while loading the module like: modprobe <module> <parameter>=<value> ....
Parameters are listed multiple times if different descriptions were found in probes, which can be helpful to see evolution.

GPL-Browser

Daily updated index of all Piglet.ko code findings on the GPL-Browser. Last update: 2024-04-19 20:13 GMT.
The Files header attempts to list the files which belong to this module. Useful if a directory contains multiple modules.
The Browse column points to the Path of the Makefile referring this code on the gpl.boxmatrix.info service.
The SoC column lists the Chip-Codenames, the Model column lists the nicks of the Box-Models.
The Diff column links the comparison of the AVM Kernel to the pristine original from Kernel.org.
The Download column links the full tarball the respective directory content is extracted from.
The presence of the source does not mean it fits the respective model and architecture. See the Model-Matrix where it's used.
Note that this list matches module names with hyphen (-) and underscore (_) exchangeable, same as modprobe does.
