4acdc67485 Add an assertion in the NastiIOTileLink converter
This uses an reorder queue but doesn't check to ensure that the data it fetches
from the queue is actually in the queue before using it.  It seems that during
correct operation this never breaks, but I'm trying to get the backup memory
port working again and this assertion fails with it enabled (without the
assertion the core just gets a bogus data beat dies).

Closes #16

ab30983aa9 Add support for per-way cache metadata
Exposes new parameter field SplitMetadata to determine whether the metadata array in a particular cache is stored in a single SeqMem or with one SeqMem per way.

Fix the backup memory port
2016-02-27 12:19:55 -08:00

a0f3189c74 Change MIF_DATA_BITS back to 64
It turns out the Chisel C++ backend can't emit correct initialization
code for a 128 bit wide NastiROM.  Rather than trying to fix Chisel, I'm
just going to hack up the backup memory port Verilog harness a bit more
to make it work.

Note that the backup memory port Verilog already couldn't take arbitrary
parameters for MIF_*, so it's not like we're losing any flexibility
here.

7319f430d0 Fix the backup memory port on multiple-channel configs
The backup memory port doesn't work on multi-channel configurations, it
just screws up the Nasti tag bits.  This patch always instantiates a
single-channel backup memory port, which relies on the memory channel
selector to only enable a single memory channel when the backup memory
port is enabled.  There are some assertions to make sure this happens,
as otherwise memory gets silently corrupted.

While this is a bit of a hack, the backup memory port will be going away
soon so I don't want to spend a whole lot of time fixing it.  The
generated hardware is actually very similar: we used to elaborate a
Nasti arbiter inside the backup memory support, now there's one outside
of it instead.

7c0c48fac4 Resurrect the backup memory port
We need this to work for our chip, and it's not been tested in a long
time in upstream -- it didn't even used to build since the Nasti
conversion.  This makes a few changes:

 * Rather than calling the backup memory port parameters MEM_*, it calls
   them MIF_* (to match the MIT* paramater objects).  A new name was
   necessary because the Nasti stuff is now dumped as MEM_*, which has
   similar names but incompatible values.

 * p(MIFDataBits) was changed back to 128, as otherwise the backup
   memory port doesn't work (it only send half a TileLink transaction).
   64 also causes readmemh to bail out, but changing the elf2hex parameters
   works around that.

 * A configuration was added that enabled the backup memory port in the
   tester.  While this is kind of an awkward way to do it, I want to
   make sure I can start testing this regularly and this makes it easy to
   integrate.

8c73d10fe1 Support SCR address generation with __OFFSET at the end 2016-02-25 21:57:37 -08:00
Palmer Dabbelt
ebffd69b8e Provide both __OFFSET and __PADDR for SCR entries
This was recently changed to write out physical addresses for SCR file entries,
but to bring up the chip we need SCR offsets so we can write the uncore SCR
file over HTIF.  This changes the map generator to generate both.

Without this change things happened to work anyway because the high bits were
getting dropped by the SCR file.

a073c37e36 The FPGA doesn't have an HTIF clock divider
We used to just be writing the SCR anyway, but now that the SCR maps are
automatically defined VCS will detect the missing SCR and bail out when
compiling test harness code.  This patch just doesn't write the HTIF SCR when
there isn't one.
