The FIFO size and full threshold need to be enough to hold if necessary all the pending read data requests from the WB slave. In the case of the Spartan-6 DDR controller being the WB slave, the FIFO needs to be able to store up to 192 words (128 from the controller itself, plus 64 from our wrapper). Since the GN4124 is used primarily on the SPEC, this is now the default value for the L2P DMA master. Signed-off-by:

This bug was not affecting the design, as it would read once from an empty FIFO only after the transfer was done. Signed-off-by:

This commit fixes an issue that would cause the L2P DMA to drop some data when the WB slave would stall at the same cycle as the dual-clock FIFO would raise the 'full' flag. The WB state machine has been redesigned in order to solve this issue and make sure that data is properly retained when this condition appears. Signed-off-by:

3.0.0 - 2020-07-27 ================== https://www.ohwr.org/project/gn4124-core/tree/v3.0.0 Added ----- - hdl: SystemVerilog BFM and testbench. - hdl: Add wrapper with wishbone records and slave adapters. - hdl: Add generics to tune the depths of the various async FIFOs. Changed ------- - hdl: Major rewrite of DMA engine, in particular the L2P DMA Master. - hdl: Major cleanup of resets and cross-clock domain synchronisation. - hdl: Stop using coregen FIFOs, switch to FIFOs from general-cores. - hdl: Make DMA optional (g_WITH_DMA generic). - hdl: Use cheby to describe registers, only one interrupt (level). - hdl: Test, verify and enable byte swap feature. - hdl: Extend SV BFM with tasks to read/write from simulated host memory. Fixed ----- - hdl: Fixed incorrect 64-bit DMA transaction generation bug. - hdl: Allow larger DMA reads (up to the full 32 bits of the "length" register) for L2P DMA master. - hdl: Add flow control to the write buffer of the BFM to prevent overflows during 'wr' commands. - hdl: Fix swapped bits in attributes. - hdl: Handle host 32-bit address overflow in L2P DMA master. - hdl: Fix bug in BFM not respecting P2L_RDY during DMA writes. - hdl: Fix bug in BFM not accepting 4096B writes.
