stekernis booting with rootfs over nfs supposed somehow broken on recent openrisc kernels/nfs servers, or is it just me that is doing something wrong?13:59
stekernmounting the nfs works when booting with initramfs, so the server setu should be ok, i guess14:03
LoneTech_I don't know any specific reason that should be broken15:15

stekernbut, this is before busybox kicks in, in busybox i can mount the share15:30
stekernthat doesn't rule out nfs3/nfs4 issues though, I have enabled nfs4 support in the kernel though15:32
LoneTechstekern: no, sorry16:05
21WAAKUO3stekern: (zero delay slot penalty) you're right on having to have all branch targets being calculated in the fetch stage for zero branch/fetch delays to occur16:07
21WAAKUO3your branch prediction sounds interesting. It'd be very interesting to see the results of what branch strategy works best16:13
21WAAKUO3regarding data endianess, I think it'd be easy to swap the endianness, perhaps just in the LSU. I can't think of anything which manipulates the different bytes/shorts in the 32-bit word, except for maybe the sign extension instructions16:16
21WAAKUO3very odd... my name is somethign random - I didn't even check that16:18
-!- You're now known as juliusb16:18
stekernjuliusb: kind of guessed it was you hiding behind that odd nick =p16:28
tremHi all, I've got a little question, where is the latest code for ork1ksim ? (on svn   or on git
stekerntrem: I think the github one is the most up to date17:45
tremstekern: thanks17:45
tremgot an error on "make check"17:45
stekernjuliusb: I agree, it'll be interesting to check different branch prediction strategies, and I think it'd be cool to make the actual prediction part pretty modular, so you could go overboard and do some really fancy dynamic branch prediction, just for the kicks19:02
stekernbut right now, I think there are still more bugs in the pipeline control, I see some crashes that I've not seen before adding it19:03
stekernmost pipeline control changes are in the fetcher, so it's kind of expected to be a pita...19:03
stekernthis nfsboot is driving me crazy, it's not working with an old kernel and another nfs server neither21:08
stekernit actually seems the "board" isn't sending anything (apart from the dhcp request, that succeeds)21:09
stekernI bet this is something silly, like a typo in the ip-address or something, but I've double checked a million times21:11
stekernconsole=uart,mmio,0x90000000,115200 root=/dev/nfs nfsroot=\21:12
stekernsroot,rw,nolock ip=dhcp rw21:12
stekernis the kernel command line...21:13
