[PATCH v3 0/7] CTU CAN FD core support |
Date: |
Mon, 14 Sep 2020 10:09:01 +0200 |
CTU CAN FD is an open source soft core written in VHDL.
It originated in 2015 as Ondrej Ille's project at the
Department of Measurement of FEE at CTU.
Integration for Xilinx Zynq and Intel based SoCs is available
as well as support for PCIe integration of the core.
The core sources
https://gitlab.fel.cvut.cz/canbus/ctucanfd_ip_core
The controller model and QEMU CAN subsystem extension to CAN FD
has been implemented in frame of bachelor theses of Jan Charvat.
The development branch ctu-canfd in CTU local project repository
https://gitlab.fel.cvut.cz/canbus/qemu-canbus

in Prague, Faculty of Electrical Engineering at

Patches v3 updates:
- resend triggered by switch to DECLARE_INSTANCE_CHECKER
in mainline. I try to follow mainline as time allows.
- SJA1000, CTU CAN FD and SocketCAN support retested
with QEMU mainline from 9/12/20 10:17 PM
- Added Reviewed-by: Vikram Garhwal
to reviewed and tested patches which are used as common
CAN FD base at Xilinx
- Added Vikram Garhwal to MAINTAINERS file as the second person
who has interrest in QEMU CAN (FD) support and would
like to be notified about changes and help with reviews.
- excuse massive TO/CC list but I do not know who has and who
does not interrest in the series. If you sent me that
it is unwanted load for you to be patch series addressees,
I would remove you from my git send command arguments.
Patches v2 updates:
- CTU CAN FD IP core emulation tested on x86 host
with big-endian MIPS MALTA target as well.
This helped t correct Linux driver to support
big-endian systems.
- CTU CAN FD IP core emulation updated to pass CAN frame
data correctly on big-endian host systems. Big-endian
host not tested, would required whole QEMU build
for MIPS MALTA or big-endian POWER and run it nested
emulation, because I have no access to Linux based big-endian
system capable for QEMU build.
- Makefile.objs changes applied to meson.build and Kconfig.
- The common CAN support update for CAN FD tested and reviewed
by Vikram Garhwal from Xilinx. They base their CAN FD
controllers emulation on our work.
- Vikram Garhwal agrees to help with common QEMU CAN bus
infrastructure reviews. I add him and myself into maintainers.
- Corrected SJA1000 dependencies in Kconfig after (probably)
automated switch to meson build from make build.
Please, let me know if somebody from recipients list does
no longer have interrest in QEMU CAN bus emulation
and I would remove you from recipients list to not load
you by uniteresting content in future.
Jan Charvat (5):
net/can: Initial host SocketCan support for CAN FD.
hw/net/can: sja1000 ignore CAN FD frames
net/can: Add can_dlc2len and can_len2dlc for CAN FD.
hw/net/can/ctucafd: Add CTU CAN FD core register definitions.
hw/net/can: CTU CAN FD IP open hardware core emulation.
Pavel Pisa (2):
hw/net/can: Documentation for CTU CAN FD IP open hardware core
emulation.
hw/net/can: Correct Kconfig dependencies after switch to meson build.
