| juiceme | Hi Hurrian, Stskeeps :) | 00:46 |
|---|---|---|
| Hurrian | ohai juiceme | 00:46 |
| juiceme | Read back the discussions ya had today | 00:46 |
| juiceme | Thanks to You both, Now I am running the MOSLO from ubiboot | 00:47 |
| juiceme | Have been testing it with chainloading to Harmattan yet, though | 00:47 |
| juiceme | It works "mostly" correctly there :) | 00:48 |
| *** dakovaci has quit IRC | 00:49 | |
| juiceme | For some reasons I had problems related with tracker... when booting the second stage it took quite a while to load Harmattan up and I did lose my messages and contacts. After restoring from backups, however it booted up nicely without any other hickups... | 00:55 |
| juiceme | I suspect it might have due to me messing up my second stage /sbin/preinit though. I did trim it a bit when I was experimenting with it. | 00:56 |
| *** rcg has quit IRC | 00:58 | |
| juiceme | note-to-self; must add "warning, do ay your own risk, make backups" notices really loud when releasing it :) | 00:58 |

| Hurrian | juiceme, that's great | 01:03 |
| Hurrian | Which Harmattan kernel are you running? | 01:03 |
| Hurrian | Patched Openmode or NITDroid? | 01:03 |
| juiceme | The first stage booter is patched Nemo kernel, "kernel-adaptation-n950-n9-mer-n9-2.6.32-20121301" | 01:05 |
| juiceme | However I tried, I could not fix the kexec() on the vanilla kernel | 01:05 |
| Stskeeps | evening | 01:06 |
| juiceme | evening stskeeps | 01:06 |
| juiceme | I patched it to use fixed cmdline, and added a new /proc/original_cmdline entry to store the NOLO-given cmdline | 01:07 |
| Hurrian | juiceme, ah, and that's what's passed to the kernel. | 01:08 |
| Hurrian | interesting solution. | 01:08 |
| juiceme | to boot either Harmattan or Nitdroid on it, I just change the init=/sbin/preinit_harmattan or init=/sbin/preinit_nitdroid for the second stage boot | 01:08 |
| juiceme | I thought that easiest to get to the actual cmdline. the patch is fairly small, ~4k | 01:09 |
| Hurrian | Or you could kick it straight into NITDroid, skipping the chroot process in sbin/preinit altogether. | 01:09 |
| Hurrian | [given, you've partitioned off some space for it] | 01:10 |
| juiceme | well yes, the Nitdroid preinit is streamlined so it does not do much extra stuff | 01:10 |
| juiceme | I am just running it chrooted, no extra partition | 01:11 |
| Hurrian | juiceme, so the second stage kernel is e-yes' NITDroid kernel (which we apparently are still missing the sources for?) | 01:11 |
| juiceme | yes, that is what I need to use. | 01:11 |
| Hurrian | ah. | 01:11 |
| Stskeeps | missing sources? how very android-ish | 01:12 |
| Stskeeps | :P | 01:12 |
| juiceme | However, I have not actually tested it... been playing around with just harmattan | 01:12 |
| juiceme | I should re-test it now, but previously I was not able to chainload it | 01:12 |
| juiceme | Hurrian's hunch is that it should be compiled with kexec enabled, to fix the aligment so that it can be loaded correctly | 01:13 |
| Stskeeps | did you hear about the L2 cache issue and kexec? | 01:14 |
| *** Morpog has quit IRC | 01:14 | |
| juiceme | Some while back I asked e-yes quite politely a few times for the source, but did no get it :( | 01:14 |
| juiceme | hmm no, what about it? | 01:14 |
| Stskeeps | long story short we found that kexec disabled L2 cache but kernel forgot to re-enable it | 01:15 |
| *** dakovaci has quit IRC | 01:15 | |
| Stskeeps | massive speedup | 01:15 |
| Stskeeps | :P | 01:15 |
| juiceme | oo. has that been fixed=? | 01:15 |
| Stskeeps | yeah, in the .32 kernel | 01:16 |
| juiceme | in the nokia-official 2.6.32? | 01:16 |
| juiceme | because that is what I am using as my second-stage boot | 01:17 |
| Stskeeps | no, in the nemo one | 01:18 |
| Stskeeps | it's probably an issue in nokia-official too | 01:18 |
| juiceme | okay... need to patch that in then | 01:18 |
| juiceme | might have that issue... as the 2nd stage boots fairly slow iir | 01:19 |
| juiceme | and the phone DOES feel a bit sluggish :) | 01:19 |
| juiceme | can I see if it's active/disbled from some proc entry etc.? | 01:20 |
| Stskeeps | no, we caught it with performance statistics / benchmark | 01:20 |
| juiceme | wuff | 01:20 |
| Stskeeps | even more amazing is that the sailfish demo was -before- we fixed that, so the damn thing just flies now | 01:20 |
| Stskeeps | :P | 01:20 |
| juiceme | Can you give me some pointers what files were changed, so I can diff the kernels a bit..? | 01:21 |
| juiceme | Well, it just goes to show sailfish is efficient :) | 01:21 |
| Stskeeps | https://github.com/nemomobile/kernel-adaptation-n950-n9/commit/994b4b2c91e062264c4eb19f3bb38e5fe2639e73 | 01:22 |
| juiceme | tnx | 01:22 |
| juiceme | aa, it will be fixed by idle thread by itself at some later point? | 01:23 |
| Stskeeps | yeah, but it can take ages | 01:24 |
| Stskeeps | bootup is really badly hurt by it | 01:24 |
| juiceme | well thats the bloody thing I have been wondering about, then? | 01:24 |
| Stskeeps | what are you guys working out, out of interest? | 01:24 |
| juiceme | Cos it REALLY takes ages to boot 2nd stage, the spinner spins for almost a minute.. | 01:25 |
| juiceme | hmm? | 01:25 |
| Stskeeps | well, just wondering what you're hacking on :) | 01:25 |
| Stskeeps | i'm having so many balls in the air i'm having difficulties following what community does, so :P | 01:26 |
| juiceme | multiboot loader with graphigal front-end :) | 01:26 |
| Stskeeps | alright | 01:26 |
| *** dakovaci has joined #nemomobile | 01:26 | |
| juiceme | What I like to do, is to create a toolset that can be used to make any kind of boot loader with fancy bells & whistles | 01:27 |
| Stskeeps | :nod: | 01:27 |
| juiceme | It's just for N9 as that is what I have | 01:27 |
| juiceme | also, there have been other useful stuff that's based on it, other people have used it to create backup-menu that can be used to save & load partition images in preinit phase, before OS mounts the /user stuff | 01:29 |
| juiceme | Ahh, thanks.. | 01:32 |
| juiceme | Now I checked the diff on arm/mm/proc-v7.S | 01:33 |
| juiceme | It sure is a bug in Nokia kernel, it's missing the git patch | 01:33 |
| Hurrian | juiceme: Config files + evtap + math to automatically determine hitbox size? | 01:33 |
| juiceme | hitbox size? | 01:34 |
| Hurrian | the size of the touch areas for evtap boot scripts. | 01:35 |
| Hurrian | I was thinking of putting evtap and its dependencies into the ubi-boot to make it easier to select tools. | 01:35 |
| juiceme | aa of course :) | 01:36 |
| juiceme | the map files :) | 01:36 |
| Hurrian | juiceme: for the boot selection screen, the script should count how many boot items are to be displayed, and divide the mapping accordingly | 01:36 |
| juiceme | yes, that wouls make it easier | 01:36 |
| juiceme | Up to now, I have always calculated the map file by hand, just measuring the boundaries by hand in GIMP | 01:37 |
| Hurrian | Well, assuming the screen resolution is known, it could simply be sed into the map file. | 01:38 |
| juiceme | that is if the menu icons are set up in a grid or array | 01:38 |
| juiceme | As for myself, I have "aesthetically scattered" the icons on the screen | 01:39 |
| Hurrian | Arrange them in a single column then. | 01:39 |
| juiceme | but for creating automatic menus, really easy to do it that way | 01:39 |
| juiceme | yes | 01:39 |
| *** dakovaci has quit IRC | 01:40 | |
| juiceme | and easy to create even long dialogs, with entry yes/no/back , for example | 01:40 |
| Hurrian | juiceme, maybe you should test the patched Openmode kernel and use another entry for NITDroid | 01:41 |
| Hurrian | so you can keep testing without hurting performance | 01:41 |
| *** zhxt has joined #nemomobile | 01:41 | |
| * Stskeeps is trying to make qtwayland with xcomposite_egl backend work.. | 01:42 | |
| Stskeeps | so far i've found out that SGX is a bit of a bitch with shader syntax.. | 01:42 |
| juiceme | yes | 01:42 |
| juiceme | Hey, stskeeps, about the patch. | 01:43 |
| juiceme | Is it enough to fix the cpu_v7_proc_init function? | 01:43 |
| Stskeeps | think so | 01:43 |
| juiceme | as there is also change in cpu_v7_proc_fin, where the L2 cache is switched off | 01:43 |
| Stskeeps | check rest of three | 01:43 |
| Stskeeps | er, tree | 01:44 |
| juiceme | is the fin function ever used? | 01:44 |
| Stskeeps | in kexec? | 01:44 |
| juiceme | well, like ever, if we assume that kexec() is never done from the vanilla kernel again after it is once booted | 01:45 |
| juiceme | I'm not so well-aquinted with arm assembly, c is my main dish... | 01:46 |
| *** zhxt has quit IRC | 01:46 | |
| Hurrian | juiceme, even if L2 cache is switched off in cpu_v7_proc_fin, as long as the kernel is patched to initialize L2 cache in cpu_v7_proc_init, it's fine | 01:49 |
| juiceme | good. Then I will patch the fin part also, for completeness sake :) | 01:49 |
| *** n9mx has quit IRC | 01:50 | |
| Hurrian | juiceme: just make an announcement on TMO for kernel developers | 01:51 |
| Hurrian | That should hopefully get the whiners on TMO to push e-yes to wake up. | 01:51 |
| juiceme | I will have to do that :) | 01:51 |

| juiceme | Okay, now while I am compiling the changes to tha vanilla kernel due to the L2 enable patch, at the same time I now tested 2nd stahe boot to Nitdroid. | 02:15 |
| juiceme | To my surprise it actually works :) | 02:15 |
| juiceme | altough I think the same patch should be also inserted there.... | 02:16 |
| Hurrian | juiceme: you'll need e-yes to release sources | 02:16 |
| juiceme | yes | 02:16 |
| juiceme | I do not undestand why it is so difficult, even as he has done a lot of work on it... | 02:17 |

| Hurrian | juiceme, it seems he hasn't went on nitdroid forum for some time, lemme tweet him | 02:20 |
| juiceme | sure | 02:21 |
| Hurrian | and there, tweeted. let's see how long it takes him to respond. | 02:26 |
