2025-04-25hw/net/can: Fix type conflict of GLib function pointersKohei Tokunaga1-2/+2
On Emscripten, function pointer casts can result in runtime failures due to strict function signature checks. This affects the use of g_list_sort and g_slist_sort, which internally perform function pointer casts that are not supported by Emscripten. To avoid these issues, g_list_sort_with_data and g_slist_sort_with_data should be used instead, as they do not rely on function pointer casting.

2024-12-19include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LISTRichard Henderson1-1/+0
Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match. With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.

2024-09-13hw/net/can/xlnx-versal-canfd: Fix FIFO issuesDoug Brown1-33/+3
The read index should not be changed when storing a new message into the RX or TX FIFO. Changing it at this point will cause the reader to get out of sync. The wrapping of the read index is already handled by the pre-write functions for the FIFO status registers anyway. Additionally, the calculation for wrapping the store index was off by one, which caused new messages to be written to the wrong location in the FIFO. This caused incorrect messages to be delivered.

2024-09-13hw/net/can/xlnx-versal-canfd: Simplify DLC conversionsDoug Brown1-63/+4
Use QEMU's helper functions can_dlc2len() and can_len2dlc() for translating between the raw DLC value and the SocketCAN length value. This also has the side effect of correctly handling received CAN FD frames with a DLC of 0-8, which was broken previously.

Add support for QEMU_CAN_FRMF_ESI and QEMU_CAN_FRMF_BRS flags, and ensure frame->flags is always initialized to 0. Note that the Xilinx IP core doesn't allow manually setting the ESI bit during transmits, so it's only implemented for the receive case.

2024-09-13hw/net/can/xlnx-versal-canfd: Translate CAN ID registersDoug Brown1-3/+50
Previously the emulated CAN ID register was being set to the exact same value stored in qemu_can_frame.can_id. This doesn't work correctly because the Xilinx IP core uses a different bit arrangement than qemu_can_frame for all of its ID registers. Correct this problem for both RX and TX, including RX filtering.

The interrupt level should be 0 or 1. The existing code was using the interrupt flags to determine the level. In the only machine currently supported (xlnx-versal-virt), the GICv3 was masking off all bits except bit 0 when applying it, resulting in the IRQ never being delivered.

2024-06-21hw/net/can/xlnx-versal-canfd: Fix sorting of the tx queueShiva sagar Myana1-1/+4
Returning an uint32_t casted to a gint from g_cmp_ids causes the tx queue to become wrongly sorted when executing g_slist_sort. Fix this by always returning -1 or 1 from g_cmp_ids based on the ID comparison instead. Also, if two message IDs are the same, sort them by using their index and transmit the message at the lowest index first.
