| -!- blueCmd_ is now known as blueCmd | 02:59 | |
| wallento | mithro: no | 03:29 |
|---|---|---|
| wallento | I am not sure why | 03:29 |
| _franck__ | mithro, wallento : I think we should run gdb regression tests to get some numbers then send patches upstream. I think jeremybennett can help to get some approval or at least support | 04:03 |
| mithro | _franck__: hrm? | 04:03 |
| _franck__ | we should test gdb with its own test suite. Then if failure numbers are too high, fix things | 04:05 |
| _franck__ | then send patches to get or1k upstream | 04:05 |
| mithro | _franck__: SGTM | 04:06 |
| _franck__ | I think wallento was volunteer for that :) | 04:07 |
| wallento | _franck__: lol, not really ;) | 04:52 |
| shorne | wallento: _franck__: I am thinking of rebuilding my toolchain, ill check it out when I get to gdb | 05:19 |
| _franck__ | cool thanks | 05:19 |
| shorne | I was getting weird behavior debugging gdb with the remote mor1kx target, so I did want to test gdb to see if it actually is all sane. The regression tests sound good | 05:20 |
| shorne | debugging through gdb, not debugging gdb itself ;) | 05:20 |
| olofk | How come no one has implemented or1k support? http://www.capstone-engine.org/ | 07:08 |
| _franck__ | do we have a date for orconf 2016 (or whatever you call it) ? | 11:47 |
| olofk | _franck_: 7-9 October in Bologna | 12:03 |
| andrzejr | shorne, last time I have seen such crashes they were caused by (my) memory controller errors. | 14:23 |
| _franck_ | olofk: thanks | 15:43 |
| Andy___ | hi there | 17:00 |
| Andy___ | is this place alive? | 17:01 |
| olofk | Andy___: From time to time | 17:01 |
| Andy___ | :) | 17:01 |
| Andy___ | I was wondering how active the OpenRISC project still is | 17:02 |
| olofk | Not that much activity nowadays, but there are still new hw and sw features added and support for more hw targets | 17:09 |
| Andy___ | thanks for the info olofk, is it because of other open architectures or loss of interest by the community? | 17:11 |
| olofk | RISC-V has been getting a lot of attention last year | 17:12 |
| olofk | And many people seem to enjoy building things from scratch instead of maintaining existing stuff, so there has been a lot of basic stuff rewritten for RISC-V | 17:13 |
| olofk | Like toolchains, OS support, a ton of new UARTs and SPI controllers etc | 17:14 |
| Andy___ | could it be that the strenght of OpenCores itself went down and pushed developers away from its projects? | 17:15 |
| Andy___ | also the more successful ones like OpenRISC? | 17:15 |
| olofk | OpenCores has done more to damage the community than help it the last years | 17:15 |
| Andy___ | yes, I also felt that a bit | 17:16 |
| Andy___ | do you know who is still maintaining the site? | 17:16 |
| olofk | Yes, I do | 17:16 |
| Andy___ | is there a way to get in contect with someone? | 17:17 |
| Andy___ | * contact | 17:17 |
| olofk | But we started FOSSi Foundation last year to have a independent body that could work to improve Open Source Silicon | 17:18 |
| olofk | And one of our main projects is a new site called librecores.org | 17:18 |
| olofk | We have talked to the OpenCores owners, but we had different goals, so we will not pursue that any further | 17:19 |
| Andy___ | I am browsing about librecores and fossi | 17:20 |
| Andy___ | i didn't know they existed | 17:21 |
| olofk | We are still trying to reach out to people | 17:22 |
| olofk | And there are several projects in the works, so if you are interested, make sure to check in regularly, or follow us on twitter, join our mailing lists or subscribe to our rss feed to get more info | 17:24 |
| olofk | Or ask here :) | 17:24 |
| olofk | Or in #fossi or #librecores :) | 17:25 |
| mafm | there's also the sh4 folks, toolchain and other things seem to be in a good shape, I haven't followed the news from the group | 17:25 |
| olofk | mafm: You're talking about the j-core guys? | 17:25 |
| mafm | yeah | 17:25 |
| Andy___ | I see you're in contect with people at CERN also! | 17:26 |
| mafm | there's still a Debian port going on, which comes from many years, toolchain and everything should be working | 17:26 |
| olofk | I haven't really got what they're doing. On their page they say that they've talked to the OpenRISC people, but except for a mail that I sent about two years ago, no one has heard anything from them | 17:26 |
| olofk | Andy___: Yes indeed. Our yearly conference, orconf, was held at CERN last year, and we have been talking a lot to several of the people there over the years | 17:27 |
| mafm | dunno | 17:27 |
| olofk | mafm: A sh4 toolchain? | 17:27 |
| mafm | I think that sh4 patents are expiring, so if sh4 is still good design by todays standards (?! I wouldn't know), the ecosystem is there | 17:28 |
| mafm | RISC-V is more of an academic attempt to get things right by the things that are known by 201x, which happened to gain some industry interest | 17:28 |
| olofk | Yeah, that is a good thing. A CPU is nothing without software and IP cores to connect it to | 17:28 |
| mafm | that's the V in the name, I guess :D (incidentally, I think that they equate SH4 with RISC-III or RISC-IV) | 17:29 |
| olofk | From what I have heard, RISC-V seem to be pretty well balanced, but I couldn't tell. Despite being on the OpenRISC project for six years, I don't know much about CPU design :) | 17:29 |
| mafm | I was somehow hoping that RISC-V did progress / settle a bit quicker, the toolchain and everything is not upstreamed | 17:30 |
| olofk | Yeah, I'm actually surprised by that, given how extremely much interest they have had for some time | 17:30 |
| mafm | I have the impression that risc-v or sh4 is more for people wanting boards / computers with that arch, while openrisc attracts more people wanting to experiment with cpu designs | 17:31 |
| olofk | I'm a bit afraid that the novelty might wear off. Don't want to end up with another semi supported arch | 17:31 |
| olofk | mafm: Actually, I think RISC-V is for people interested in CPU designs. I counted 11(!) different implementations that were presented last year at orconf | 17:32 |
| olofk | Everything from supersmall to big superscalar OoO versions | 17:32 |
| mafm | I'm specially a bit frustrated with how long it's taking for them to upstream things and settle on the supervisor/priviledge ISA, it was supposed to be ready 1 year ago :-/ | 17:33 |
| mafm | olofk: yeah, perhaps that's true at one level (e.g. research projects)... I guess that the industry interest and other individuals is more about "having a CPU that can be used in boards / IoT / huge datacentres" | 17:34 |
| olofk | Yeah, that is one of the most common critiques people have. There is very little insight in the decision-making | 17:34 |
| olofk | I agree. Most people would probably be fine with a standard ARM-like RISC-V core with the right peripherals | 17:35 |
| olofk | My interest is more in the ecosystem around the CPU than the CPU itself | 17:35 |
| olofk | But now it's time to sleep. Good night | 17:37 |
| mafm | olofk: nite :) | 17:37 |
| olofk | Or good whatever part of day in your local timezone | 17:37 |
| mafm | british summer (hah!) time | 17:38 |
| olofk | I hate timezones. Worst idea ever | 17:38 |
| Andy___ | good night mafm | 17:38 |
| mafm | Andy___: it's olofk the one going away | 17:38 |
| Andy___ | opsy | 17:39 |
| Andy___ | good night olofk | 17:39 |
| Andy___ | thanks for all the info! | 17:39 |
| mafm | I'm mostly interested in anything that can be used in a computer or a small device, free to implement and so on | 17:39 |
| mafm | I think that this is going to become more and more important in the future, with backdoors and whatnot | 17:40 |
| mafm | I'd be happy with openrisc, but probably nobody is producing silicon that can be purchased. I don't have a good use for openrisc on FPGAs, other than learning about design and stuff | 17:41 |
| mafm | so I had some hopes about risc-v/lowrisc producing something, but it's moving at a glacial speed sometimes, and actually unknown if it's moving or not in others | 17:42 |
| mafm | and as olof said, everything quite secretive / hard to collaborate from outside | 17:42 |
| Andy___ | goodbye everyone | 18:14 |
