stekernah, ok... appeareantöu I really should stop declaring wires in the middle of things, because I (or somebody else) will end up using them above the declaration at some point01:13
stekernappearantly =P01:14
mor1kx[mor1kx] skristiansson pushed 2 new commits to master:
mor1kxmor1kx/master b485103 Stefan Kristiansson: cappuccino/lsu: move dbus_access declaration to top of file01:33
mor1kxmor1kx/master 8821393 Stefan Kristiansson: execute_alu: simplify threestage mul logic01:33
stekern(4000) well, you have to be pick a number, and it's always good to set the bar high01:34
stekernespresso is ~350001:34
stekernbut that's of course without cache and mmu01:34
stekernor1200 is ~470001:34
stekernbut that's with 1-way cache01:34
stekernchanging the cappuccinos caches to 1-way slims it down to about ~500001:35
olofkWhere are the most up to date build instructions for the or1k toolchain?06:50
olofkah.. found it06:51
olofkHmm.. I think I'm doing something wrong. What does this mean? /opt/openrisc/lib/gcc/or1k-elf/4.8.0/../../../../or1k-elf/bin/ld: cannot represent machine `or32'07:34
olofkThis turns up when I'm trying to build the orpsocv2 tests. I'm pretty sure I had that working last time I tried07:36
stekernorpsocv2 is still using the or32 toolchain, no?07:40
olofkI thought it was just to change the toolchain prefix07:40
stekernand you have done that?07:40
olofkI tried a quick grep, but couldn't find any more references to or32 tools07:40
stekernok, exactly where do you get that message?07:41
olofkI mean, it's trying to run or1k-elf-gcc and or1k-elf/bin/ld07:41
olofkmake or1200-basic.elf in sw/tests/or1200/sim07:41
stekernare all the ld scripts updated?07:41
olofkgood question. Probably not07:41
olofkHmm.. where do I find them?07:42
stekernhold a sec07:42
olofkIt works now07:44
olofkI'm having vacation today, so I hope I can finally get some real work done :)07:45
stekernthat's the spirit07:48
stekerncan't you have concatenated signals in VHDL port maps?07:48
stekernI'm trying to do: my_signal => X"4" & X"2" & X"1",07:49
olofkstekern: No, but you can split the port07:49
olofkmy_signal(3 downto 0) => x"4"07:50
stekernoh, good tip07:50
stekernthat looks nicer too07:50
olofkA word of warning though. You can't leave parts of an output port open. One of VHDL's many amazing features08:26
stekernyeah, I wouldn't expect it to allow me to do that08:28
stekernthe most annoying feature of VHDL must be that hexadecimal values have to be multiples of 408:31
olofkChanged in the latest revision08:34
_franck_it's been improved in VHDL-200808:35
_franck_you can now have S := 6x"0f";  -- specify width 608:35
olofkThere's a lot of nice stuff for the next revision. I submitted a feature request to be able to use records in ports with mixed inputs and outputs08:36
stekernwhat kind of tool support is there for VHDL-2008?08:41
stekernI think this design is altera only though08:41
olofkAt least modelsim (questasim) and Synplify has implemented most of the stuff08:42
_franck_quartus does08:47
stekernyup, I found the checkbox08:48
stekernonce again, ranting in irc is useful ;)08:48
