| poke53281 | Today I was shoicked, when I received a pull request from stekern. | 08:15 |
|---|---|---|
| poke53281 | for Javascript | 08:16 |
| poke53281 | stekern on the dark side of the force. | 08:22 |
| poke53281 | What was the reason for the patch anyhow. rtems? Do you know, how to use the example? | 08:23 |
| olofk | poke53281: Is it a timer patch? I know that he needed some extra features for his lk kernel as well | 08:39 |
| poke53281 | olofk: Yes, a timer patch. | 08:43 |
| poke53281 | lk kernel? | 08:44 |
| olofk | https://github.com/travisg/lk | 08:45 |
| olofk | Looks like it's used as a recovery/bootloader kernel for many Android devices | 08:46 |
| -!- Netsplit *.net <-> *.split quits: _franck_ | 09:05 | |
| poke53281 | Hmm, Ok | 09:06 |
| stekern | poke53281: http://oompa.chokladfabriken.org/openrisc/jor1k/demos/lk.html | 09:18 |
| poke53281 | TODO very urgent: Add terminal history ... | 09:37 |
| poke53281 | Again no clue, what to do | 09:38 |
| poke53281 | But at least, I can calculate fibonacci numbers. | 09:39 |
| poke53281 | But again great job stekern. | 09:49 |
| olofk | poke53281: Fibonacci series is like the Hello world or blinking LED for mathematicians and language designers :) | 09:49 |
| poke53281 | Well, this was the last option in the help command. The first commands I can't see, because I don't have a scrollback buffer. | 09:50 |
| poke53281 | Wonder, what the "hello world" equivalent is for physicists? Dropping an apple? | 09:51 |
| olofk | lol | 09:53 |
| olofk | YEAH! Gravity works! | 09:53 |
| juliusb | I love this jor1k instance proliferation | 10:13 |
| olofk | Yes, it's a great way to show off new stuff | 10:20 |
| olofk | Is anyone using FuseSoC with python 2.7 btw? I'm getting some strange errors | 10:20 |
| olofk | Seems to work now after a reinstall | 10:22 |
| olofk | At least I didn't have to clean out the registry and disable anti virus programs :) | 10:23 |
| olofk | Is opencores svn down? | 10:24 |
| stekern | poke53281: it's not so much you can do there, it's just some test applications built in there | 12:53 |
| stekern | but with the timer patch applied all of the tests works as well in jor1k as in or1ksim | 12:54 |
| olofk | I like the synergies here. jor1k was great to test the toolchain and find bugs/missing features in the RTL. Now we port new OSes and find missing features in jor1k | 13:03 |
| poke53281 | olofk: Well, you know that the missing features are obvious for me. I just didn't expect to ever run another operating than lLinux with this emulator. | 13:23 |
| stekern | mmm, no really major things though. Linux doesn't use that mode, I guess poke53281 omitted the support for that | 13:24 |
| poke53281 | So I implemented exactly the things necessary to run Linux. | 13:24 |
| poke53281 | And Linux uses only one timer mode. | 13:24 |
| poke53281 | exactly stekern. | 13:24 |
| poke53281 | I also don't support add with carry flag. | 13:25 |
| poke53281 | because gcc doesn't use it. | 13:25 |
| poke53281 | The flag thingy is more or less broken Did someone ever tested the proper setting of flags in or1ksim? | 13:26 |
| stekern | flag thingy? | 13:27 |
| poke53281 | Yes, the flags in the supervisor register. | 13:27 |
| poke53281 | I remember that when I read the or1ksim code a long time ago, that there were some comments because of the flags. | 13:28 |
| stekern | ah, no probably not... | 13:28 |
| poke53281 | That the documentation is wrong or that there was a question in the comments, if the flags are correctly implemented. | 13:29 |
| poke53281 | add and sub with carry is kind of important for 64 Bit values. | 13:30 |
| poke53281 | on 32 Bit machines | 13:30 |
| poke53281 | I have never looked at our compiled code. Probably done with l.sf.... | 13:31 |
| stekern | I really want to try out 'bandvigs' fpu stuff | 13:31 |
| stekern | I wonder how complete they are at this point | 13:31 |
| poke53281 | I am curious as well. | 13:32 |
| stekern | right now I'm reading code I've written 1.5 years ago and I'm trying to understand what it does.. | 13:35 |
| poke53281 | You should accustom yourself to write your current alcohol level in the comments when you code :) | 13:36 |
| poke53281 | But I have such problems too. But not with programs, which I have written from scratch. Only with programs, were I had to follow other design principles and variables and functions. | 13:38 |
| stekern | I'm pretty sure it was fairly low when I wrote it, but I'm not so sure about my current state | 13:39 |
| stekern | fwiw, this is what I'm looking at: https://github.com/skristiansson/linux/commit/f8dbfc43d7bdeea64810e683f4eec7adb5f3aeda | 13:39 |
| poke53281 | Looks like part of your hardware TLB lookup | 13:41 |
| stekern | it is, and there was some nice cleanups in the layout of the Linux PTE done for the sw lookup as weel | 13:42 |
| stekern | and I'd like to apply those to lk npw | 13:42 |
| stekern | s/npw/now | 13:42 |
| poke53281 | I remembered, that I asked you to use a supervisor register to activate this feature :) | 13:44 |
| olofk | Looks like I will have to change all references from opencores svn to github in orpsoc-cores. It's very shaky nowadays | 13:45 |
| poke53281 | And you asked about the discrepancies between the implementation in the Linux kernel and in the specification. | 13:46 |
| stekern | hmm, I think that's slightly unrelated | 14:02 |
| stekern | the discussion was whether a 0 value in the PTBP field would be regarded as hw tlb refill disabled | 14:04 |
| stekern | olofk: yeah, I had some troubles fetching the simple_spi core when I needed to check the orpsoc-cores changes vs orpsocv2 | 14:55 |
| olofk | LoneTech: Do you know anything about SVN problems on OpenCores? | 18:47 |
| olofk | Asked this before, but can we send in kernel patches without a kernel maintainer? | 19:10 |
| olofk | I'm releasing FuseSoC 1.2 now btw | 19:42 |
| olofk | Ok done. Just need to compile a FTP client to upload the tar ball | 19:54 |
| olofk | ok done. Bring out the cocaine! | 20:08 |
| Me1234 | Where can be working linux on de0_nano downloaded? kernel.org? | 21:05 |
