PLIC: updated to latest version from Piccolo/Flute.
MMIO_AXI4_Adapter: added workaround for Xilinx IP problem on 64-bit
AXI4 fabrics. Writes that specify 8-byte size, but only write in
upper or lower word using strobes, are converted into 4-byte size.
Core.bsv: added a notification to the Debug Module re. CPU halt.
Previously, the request went out into the fabric, and we were relying
on the fabric returning an error response. Some fabrics don't do this
reliably, so this removes that reliance on the fabric.
Now able to run multiple ISA tests in a single simulation run
connected to remote debugger DSharp, using either hart_reset or
ndm_reset between tests to bring the system back into reset state.
All Debug Module commands working:
- dm_reset, hart_reset, ndm_reset
- break (set breakpoint)
- step
- continue (until breakpoint of 'halt' command)
- halt
- read/write GPR, FPR, CSR, memory
- elf_load
Modified
src_Core/CPU/MMIO_AXI4_Adapter.bsv
Instead of aborting on axi4 mem read error, pass the error on to the core
src_Core/RISCY_OOO/procs/lib/MMIOAddrs.bsv
Added mainMemBoundAddr
src_Core/RISCY_OOO/procs/lib/MMIOCore.bsv
Update isMMIOAddr check to also check mainMemBoundAddr
src_Core/RISCY_OOO/procs/lib/MMIOInst.bsv
Update getFetchTarget to also check mainMemBoundAddr
(still TODO: allow other IO addrs other than bootRom)
