| poke53281 | Nice video stekern. Looks like scummvm is somewhat usable | 00:09 |
|---|---|---|
| poke53281 | Next step: Quake | 00:10 |
| poke53281 | :) | 00:10 |
| poke53281 | or sound | 00:12 |
| stekern | poke53281: yeah, sound is on the list | 02:17 |
| stekern | I tried compiling sdldoom, but that segfaults | 02:18 |
| stekern | hmm, I get an undefined references to __tls_get_address in alsa-lib-1.0.27 | 03:06 |
| stekern | and to be clear on the sdldoom, the compilation doesn't segfault, but the produced executable | 03:06 |
| stekern | also on my list: get this up and working on the de0-nano board | 03:13 |
| stekern | might be the motivation I need to finally try out the touch screen controller on the LCD addon I have | 03:14 |
| stekern | poke53281: btw, you can avoid the sound crash workaround (add of return in scummvm) by setting the SDL_AUDIODRIVER environment variable to dummy | 03:46 |
| stekern | I've got a bit of an unusual git problem, I'd like to cherry-pick a set of commits from one repo into a seperate directory in another repo | 07:14 |
| stekern | i.e. in repo1 I have git-root/ and everything from start of that repo I'd like ontop of repo2 into git-root/subdir/ | 07:16 |
| stekern | the only way I can think of from the top of my head is to format-patch the whole repo and sed the paths in the patches and then apply them | 07:17 |
| stekern | but if there is a better way, I'd like to learn it | 07:18 |
| simoncook | I think you can do that if you use git filter-branch --tree-filter 'mkdir newdir; mv * newdir' on the original repo and then cherry-pick | 07:18 |
| stekern | also, if keeping my tags would be possible, that'd be a bonus | 07:19 |
| stekern | simoncook: oh, ok, thanks! I'll read up on filter-branch | 07:19 |
| stekern | yup, filter-branch sounds exactly like what I was looking for | 07:22 |
| olofk | Git seems like a nice OS. It only lacks good version control software | 07:46 |
| stekern | he he, good emacs reference there =P | 07:50 |
| stekern | too bad it isn't true | 07:51 |
| jeremybennett | Is it my imagination, or is opencores.org running very slowly this morning? | 07:52 |
| stekern | simoncook: it worked fine, but with the last example described in the man pages: https://www.kernel.org/pub/software/scm/git/docs/git-filter-branch.html | 07:54 |
| stekern | but the important pointer to the command was what I needed, so thanks a lot! | 07:59 |
| olofk | jeremybennett: I think it's a daily backup at around 11pm CET. It might be that you are seeing | 08:43 |
| olofk | s/pm/am | 08:43 |
| jeremybennett | olofk: Thx | 08:52 |
| stekern | n | 08:59 |
| stekern | oops | 09:00 |
| ysionneau | 09:16 < stekern> i.e. in repo1 I have git-root/ and everything from start of that repo I'd like ontop of repo2 into git-root/subdir/ < maybe I don't get what you are doing but shouldn't you use submodules ? | 09:39 |
| stekern | perhaps if I'd be in control over repo2, yes | 09:44 |
| lnax | hi there, i am trying to port xv6 (educational os from MIT) to openrisc cpu. I was reading throw source code and i have problem understanding assembly code part. At first i want to turn on paging. I read theory about paging but i have no idea what to do. There is how they do it on x86 http://pastebin.com/3Lr7tUKQ | 10:06 |
| stekern | lnax: there's probably a bit more configuration of the paging system than the short snippet you posted there | 11:08 |
| stekern | basically, all that happens there is that the address of the page directory is written to cr3 (which is x86's page table base pointer register) | 11:09 |
| juliusb | I hope people saw my typo-ridden announcement about registration for ORCONF2013 (is it ORCONF2013 or ORCONF 2013? I need to be consistent!) | 11:16 |
| juliusb | http://lists.openrisc.net/pipermail/openrisc/2013-August/001832.html | 11:16 |
| juliusb | stekern: awesome work on the SCUMMVM stuff btw, that's so cool | 11:18 |
| juliusb | you always do the coolest things with OpenRISC | 11:18 |
| juliusb | first bump maps, now games! | 11:18 |
| stekern | ah well, most credit goes to poke53281 on this one | 11:19 |
| juliusb | actually, hardware TLB replacement and a 5-stage pipeline CPU is cooler, actually ;) | 11:19 |
| juliusb | pfft, I'm not proof-reading well today | 11:19 |
| juliusb | yes, that was a big effort to get all of that Linux stuff compiling properly | 11:19 |
| stekern | a 6-stage pipeline CPU is even cooler ;) | 11:21 |
| juliusb | ... is cappuccino 6 now? | 11:24 |
| stekern | mmhm | 11:24 |
| juliusb | haha | 11:24 |
| juliusb | i've been paying attention, haven't i? | 11:24 |
| stekern | mmhm =P | 11:26 |
| stekern | it has been for quite some time actually, 8 months to be more precise: https://github.com/openrisc/mor1kx/commit/8fda585e1e02c9afc82ad5be25333a1fef01049c | 11:31 |
| ysionneau | lm32 is 6 :) | 11:31 |
| ysionneau | but no hardware tlb replacement :' | 11:32 |
| stekern | speaking of typo-ridden, that commit has it sets of typos too... | 11:34 |
| juliusb | pfft, lm32 | 11:35 |
| juliusb | stekern: ever since MMUs? | 11:35 |
| stekern | ysionneau: yeah, I know, I'm not completely oblivious over lm32, I'm not going to hide that I've taken a skyhigh look at it and adopted some things from it onto cappuccino | 11:36 |
| stekern | juliusb: naah, that was before we had MMUs (I think) | 11:37 |
| ysionneau | stekern: I should have a look at cappuccino one day :) | 11:39 |
| stekern | you indeed should! ;) | 11:42 |
| stekern | and then when you're done with the netbsd port for lm32, you can do one for openrisc as well =P | 11:42 |
| ysionneau | ahah | 11:43 |
| stekern | should be a breeze when you've got the hang of it, right? | 11:43 |
| ysionneau | I hope I will see the end of this project one day | 11:43 |
| ysionneau | that's hell of a work :/ | 11:43 |
| ysionneau | and I have very little time | 11:43 |
| ysionneau | but that would be so cool :) | 11:43 |
| stekern | I can very well imagine that, but it's a cool effort your doing there | 11:43 |
| stekern | s/your/you're | 11:43 |
| ysionneau | thanks ! | 11:44 |
| ysionneau | I enjoy it as well, but it's very frustrating to not be able to do it as fast as I would like too | 11:44 |
| ysionneau | to* | 11:44 |
| ysionneau | The most cool thing is I'm learning a lot :) | 11:50 |
| olofk | juliusb: I saw a documentary on how your people were struggling in the eighties. I didn't know about the shortage of petrol | 11:53 |
| stekern | ysionneau: yeah, learning, that's my main motivation as well | 12:05 |
| stekern | impressive tickets we got for orconf | 12:14 |
| juliusb | olofk: I wasn't aware of this? | 12:16 |
| olofk | juliusb: Yeah, I think it was called Mad Max. There was a guy in it who looked a lot like Mel Gibson | 12:16 |
| stekern | lol | 12:50 |
| juliusb | haha | 13:22 |
| juliusb | very good olof | 13:22 |
| juliusb | olofk: so, any word on whether you're likely to make it for orconf? | 13:24 |
| juliusb | i'm really hoping you can! | 13:24 |
| stekern | me too! | 13:25 |
| juliusb | I kinda took it that you were still likely to be able to come on the 5th/6th | 13:25 |
| stekern | especially since I'm the main catalyst for mixing up with the dates | 13:25 |
| olofk | I think it will be hard to make it to 5th/6th, but I'll try | 13:27 |
| juliusb | ok, yeah sorry about any difficulty it causes, didn't mean to cause any | 13:29 |
| olofk | I don't care about your stupid conference anyway. I think it sucks! | 13:30 |
| juliusb | hehe | 13:30 |
| juliusb | it will without you <3 | 13:31 |
| olofk | :) | 13:31 |
| olofk | Has anyone except for the usual suspects registered yet, btw? | 13:36 |
| juliusb | .... I don't know how to check actually | 13:36 |
| juliusb | just pinged the ever-helpful Andrew Back to find out | 13:40 |
| olofk | ysionneau: Are you thinking about coming? It would be fun to learn a bit about what's going on in the lm32/MilkyMist community | 13:46 |
| olofk | Because you're that guy, right? :) | 13:46 |
| juliusb | totally! | 13:48 |
| ysionneau | I'm playing a bit with Milkymist and lm32 yes :) | 13:49 |
| ysionneau | I've tought about coming to learn about openrisc but I did'nt take the time to read all the emails yet about the organization | 13:50 |
| ysionneau | is there a schedule? | 13:50 |
| juliusb | come to Cambridge on October 5th/6th and tell us abuot it, either formally via a presentation, or over beer. lots of beer. :) | 13:50 |
| juliusb | not yet | 13:50 |
| ysionneau | or just a list of presentations? | 13:50 |
| ysionneau | even without the timing | 13:51 |
| juliusb | well, we do have a schedule we try to stick ti | 13:51 |
| juliusb | s/ti/to/ | 13:51 |
| juliusb | I expect that's better than an untimed thing, but there's also meal breaks and dinner afterwards where there's no fixed schedule of topics | 13:51 |
| olofk | Yeah, we should get out the list of applied talks as soon as they come in. That will make it more likely for other to turn up or submit talks | 13:51 |
| juliusb | OK, I'll make sure I put up the ones I've had so far sometime soon | 13:52 |
| olofk | s/applied/submitted | 13:52 |
| olofk | And it will give me something to tweet about :) | 13:52 |
| ysionneau | yes a list of submitted talks would be nice :) | 13:52 |
| ysionneau | more appealing than "WIP" | 13:52 |
| ysionneau | so far I only have this URL: http://opencores.org/or1k/OpenRISC_Project_Meeting | 13:52 |
| ysionneau | is that all the published information ? | 13:52 |
| juliusb | yes | 13:53 |
| olofk | It's a lot more information available at the dedicated site orconf.org ;) | 13:55 |
| ysionneau | is the Linux port for OR1200 using the MMU? or is it mmu-less uclinux ? | 13:58 |
| olofk | It uses the MMU | 14:05 |
| ysionneau | nice :) | 14:06 |
| stekern | I got "sound"... or should I say noise | 17:11 |
| stekern | could be a problem in my AC97 driver though, I get this: "WARNING: SDL mixer output buffer size: 8192 differs from desired: 2048!" | 17:12 |
| stekern | and then a lot of "ALSA lib pcm.c:7316:(snd_pcm_recover) underrun occurred" | 17:12 |
