02:09.34detulehey jonpry
02:10.14detulemeant to ask you about this +       add     r0, r4, #0x00800000 >> (SECTION_SHIFT - PMD_ORDER)
02:10.14detule+       orr     r3, r7, #0x00800000
02:11.34jonprysetting up idmap ramconsole?
02:12.06jonpryyou see 3.5 kernel?
02:12.10detuleyeah need to start trying to boot 3.4....whenever i can get around to putting real life on hold
02:12.21jonprylol
02:13.11jonpryi want to try porting to D3, but we still don't have a good stock kernel running
02:13.47detulewhat's 0x00800000 ?
02:13.52jonpryso you should be able to debug up until mmu_enable without that
02:14.03jonprywell those PMD are all 1MB
02:14.13jonpryso rhod console is at 0x8e0000
02:14.32detuleand some sort of superpages 256KB big
02:14.36jonprybut we can't idmap with that granularity without it being a pain in the ass
02:15.12jonpryso that thing maps 0x800000 to 0x8fffff
02:15.49detulewish i could see that
02:16.00jonpryhmm
02:16.07jonprydon't understand?
02:17.30detulewhat's r4, phys_offset?
02:17.52jonprypointers to the page tables
02:18.25jonprythose two lines of code are really the whole deal
02:19.28jonpryin c it would looks like. pmd[ramconsole>>20]=mmu_flags|ram_console>>20;
02:20.01detuleoh thanks
02:20.10detuleok so my ramconsole is at ea100000
02:20.26detule00e0*?
02:20.31detuleinstead of 0080*
02:20.39jonpryno
02:21.11detuleoh my ramconsole is way up
02:21.13jonpryi think you might need to put it below 0xc000* anyways. but leaving that asside for a minute
02:21.50jonpryadd     r0, r4, #0xea100000 >> (SECTION_SHIFT - PMD_ORDER)
02:21.50jonpry<PROTECTED>
02:23.10jonpryer. its  pmd[ramconsole>>20]=mmu_flags|(ram_console&0xFFF00000)
02:23.25detulethanks i;ll give it a try
02:24.13jonpryat some point something will interfere if its above the 0xc*
02:39.46detulei guess i don't need this any more -               pmd_clear(pmd_off_k(addr));
02:39.46detule+               {}//TODO: hack will break the kernel once it starts running processes: pmd_clear(pmd_off_k(addr));
02:52.17jonpryi don't understand
02:52.31jonpryyou need that if ramconsole is below 0xc*
02:52.37jonpryand i think that needs to be the case
02:55.02detulealright...i'll try finding a better spot for it

19:13.22Alex[sp3dev]Cotulla: how goes it?
19:13.32Cotullagood
19:13.41Cotullaincresing my knowledge in 3D
19:13.46Cotullau?
19:15.47Alex[sp3dev]Cotulla: fine. learning about L4 microkernel by reading code and attending some lectures. no time for 3d :(. My brain explodes when I come home and all I want is get some sleep :)
19:18.30Cotullaok
19:18.34Cotullawhat about L4?
19:18.41*** join/#htc-linux helicopter88 (~helicopte@host1-112-dynamic.53-79-r.retail.telecomitalia.it)
19:18.55Cotulladid u found already why it sucks on ARMv5?
19:19.42Alex[sp3dev]Cotulla: not yet, I've played with it on ARM yet. Don't see why it should suck on ARMv5
19:19.56Cotullaokay
19:20.41Alex[sp3dev]Cotulla: have you used it? experienced problems?
19:21.48Cotullaa bit
19:24.29Alex[sp3dev]Cotulla: so, what are the problems on armv5 that don't happen on armv7?
19:25.12Cotullathey implemented memory spaces by FCSE, so it's limited like in below CE 5.2 to 32 Mb :P
19:25.26Cotullathat sucks!
19:26.28Alex[sp3dev]Cotulla: which implementation of L4 are you talking about? I've not yet looked into that part (but hope to do soon) but I guess, say, OKL4, Fiasco.OC and qualcomm's l4 are very different
19:26.46CotullaOKL4
19:27.43Alex[sp3dev]to tell the truth I have not looked at it for quite a long time. Last time I tried it was 2008 when freepk @ 4pda suggested trying it. I even compiled it, but there was literally no documentation or examples on writing drivers :)
19:28.24*** join/#htc-linux GNUtoo (~gnutoo@50.118-226-89.dsl.completel.net)
19:29.43Cotullaohh
19:29.47Cotullatalked with him today
19:29.54Cotullaabout functional coding
19:30.08Cotullado u like functional coding Alexx?
19:30.18Alex[sp3dev]Cotulla: as in haskell/ML?
19:30.24Cotullain common
19:30.28Cotullaor u feel deep love to structure coding
19:30.28Alex[sp3dev]yep
19:30.40Alex[sp3dev]Cotulla: btw, how to reach him except 4pda>
19:30.46Alex[sp3dev]does he have jabber?
19:31.02Cotulla? s??k u
19:31.20Alex[sp3dev]what?
19:31.47CotullaI seek u :D
19:32.15Alex[sp3dev]jeez. ok, will install qutim
19:32.27Cotullado u like DirectX?
19:33.01Cotullalol I suggested to him try L4 btw
19:33.01Alex[sp3dev]Cotulla: I have not tried writing code in it but in general it seems to be similiar to the new opengl (with glsl)
19:33.16Alex[sp3dev]Cotulla: so, we've closed the l4 recommendation loop?
19:33.25Cotulla?
19:33.37Cotullahe though about creation of own OS
19:33.45Cotullawith 'ideal' ideas inside
19:33.58Cotullaand I suggested him to look inside L4 to understand some basic things about OS
19:38.47Alex[sp3dev]huh. installed qutim. feels so 2000-ish
19:39.46Cotullagood that not 80s
19:41.50Alex[sp3dev]Cotulla: is his id 22XXXX70 ?
