[QEMU][PATCH v4 0/4] Introduce Xilinx Versal CANFD

Posted by Vikram Garhwal 1 year ago

Hi,
This patch implements CANFD controller for xlnx-versal-virt machine. There are
two controllers CANFD0@0xFF06_0000 and CANFD1@0xFF07_0000 are connected to the
machine.

Also, added basic qtests for data exchange between both the controllers in
various supported configs.

Changelog:
v3->v4:
    Address formatting related feedback from Peter.
    Correct dlc byte data storing if dlc is not a multiple of 4.
    Remove unnecessary LOG_GUEST_ERROR.
    Remove instance_finalize(canfd_finalize) function.
    Remove unused member of struct XlnxVersalCANFDState.

v2->v3:
    Corrected reg2frame().
    Added assert to prevent out of bound cases.
    Replace tx_id link list with GSList and removed sorting function.
    Replaced PTIMER_POLICY_LEGACY with proper timer policies.
    Corrected minor code format issues.

v1->v2
    Update xlnx-versal-virt.rst with CANFD examples and add this in 03/05 patch.
    Addressed comments for patch 02/05 and 03/05.
    Add reviewed-by tags for patch 01/05, 04/05 and 05/05.
    Change commit message for patch 02/05.
    Add SPDX license for Qtest.

Regards,
Vikram
