matteo serva 4577e41b61 Revert "moved buffers initialization" 
This reverts commit baccfb4805.
 2024-03-13 21:41:38 +01:00
matteo serva 26fe48f53d fixed driver lockup at channel 0 RX. The fpga firmware 
was using the smi address pins to determine which channel can write the complex_fifo.
The read side of the complex fifo is connected to the DREQ pin of the SMI interface on the raspberry.
The address pins on the smi interface are at logic 1 when no transfer is in progress.

This caused a deadlock condition: the SMI address pin is at 1, so the fifo cannot be filled, so the DREQ cannot be asserted and the SMI cannot start reading data.

matteo serva 75d25800bc Improved kernel module: 
- Using cyclic dma for data transfer
- removed kernel threads. Now everything done in callbacks
- keeping multiple transactions running to avoid delays
- discarding data if too late
- logging the module performance
- cleaned out the code
- modified communication with userspace to fix polling
- removed redundant locks
- changed buffers behavior to improve efficiency
- fixed compatibility with latest raspbian kernel

Fix issues adding Ubuntu users to dialout, root groups 
the echo in the first half of 'if' had back-ticks causing execution instead of just text, but the whole statement isn't needed because re-adding the user to the group is a no-op, anyway.  space within the usermod command was causing it to fail also.
