00:17.11drachensunI'm trying to install these mali libs and I dont understand something.   The instructions list mali_drv.so which I think is what X needs
00:17.17drachensunbut its not in the binary downloads
00:17.33drachensunis that only a r3pX thing?
00:19.32drachensunrm: You mean because debian doesn't have the ...eabihf cross compile package?  You can get the code sourcery package, I think that will build it just as well
00:20.00drachensunrm: seems like if you built the kernel with an hf compiler it still worked fine with a hf rootfs
00:26.15drachensunnm find the info on mali_drv
01:38.17Turlrm: is there such a thing as an 'armhf kernel'?
01:38.49Turlrm: it was my belief the kernel didn't do any floating point operations - I might be plain wrong though

08:33.12rz2klooks like odroid-x doesnt have hw3d on native linux
08:33.23rz2kI thought they had mali400 working.
08:33.37rmTurl, I thought the ABI also differs
08:33.48rmregister usage conventions and the like
08:34.17rmor maybe that only applies to MIPS o32/n32, but not here

18:27.38zubhm, I don't really understand what it does. I turned it off, and my latest build dies after several hours, so I'm wondering if it could be related
18:27.42zubanyway I leave it on
18:28.24TurlI run with it off I think
18:30.28zubwhat exactly does SUNXI_IGNORE_ATAG_MEM do?
18:30.29Turlzub: yeah it's off https://github.com/allwinner-dev-team/linux-allwinner/blob/allwinner-3.0/arch/arm/configs/zatab_defconfig#L60
18:30.56Turlit ignores the ATAG that indicates memory size
18:31.12zubhm, and what's "ATAG"?

18:32.25Turlzub: it's a bunch of configuration stuff the bootloader puts on RAM for linux
18:32.27Turlzub: http://developer.toradex.com/knowledge-base/bootloader#ATAG_List
18:33.56zubso if the ATAG is wrong on my board, it's caused by my wrong setup? does uboot put it there? is it this "other" file uboot loads to RAM?
18:35.54Turlthe proprietary uboot that ships on the stock firmware to boot android from NAND doesn't offer a proper mem ATAG
18:36.26Turland allwinner's kernel guesses the RAM instead of relying on the ATAG info
18:38.02rmzub, did you try my kernels or configs?
18:39.21zubrm: nope, but I might be interested in your configs
18:39.23rmhttp://media.romanrm.ru/a10/server/3.0.39-rm2/ works well for me on mk802
18:39.26zubwhere can I get them?
18:39.27rmno graphics
18:39.27zubok
18:39.41zubyeah, I'm running headless, at least for now. but I'd like something stable

19:13.57rmno
19:14.17rmI only have Mem:        443464
19:14.38plan_bah .. you have a 512 MB device
19:14.51rmactually I have two MK802s which are supposed to be 1GB
19:15.08rmone only sees 512MB even in Android
19:15.42plan_bstrange
19:16.08rmand this one also sees only 443MB with my kernel, but I did not check if it can access the full GB in android
19:16.38rmtoggling SUNXI_IGNORE_ATAG_MEM does not help
19:17.06rmit was $33 for me on a sale and I don't need a lot of ram; so not overly bothered by this
19:17.44plan_bI saw a config (don't know where) with the full 1024 MB on a mk802+
19:18.37plan_bI have removed all the X11 stuff, framebuffer and much more ... but still not 1024 MB on my mk802
19:19.00Turlzub: the realtek chips these things run with aren't too good
19:19.07Turl(wifi)
19:19.13rmplan_b, there was a patch recently on the mailing list, "reserve framebuffer only if mali is enabled"
19:19.17rmcould be what you need

19:23.20plan_bTurl: is the chip not good or is the antenna of the mk802 bad?
19:28.36Turlplan_b: no idea, I just know the device usually drops the connection or is apparently connected but traffic doesn't flow

19:58.43hnoTurl, yes.
19:58.53mnemocTurl: u-boot passes the info. but it might need special configuration to find your memory correctly
19:59.42Turlthe issue I'm seeing is that, on kexec, it ignores atags completely
20:00.00Turlon a normal boot they're read correctly and dumping to /proc/atags works
20:00.21hnoTurl, on kexec you need to set up the atag.

20:01.51Turland /proc/atags has the atags
20:01.53RaYmAnthen yes, it should do it for you

22:01.31hnomnemoc, good. There is no dram or clock changes after that. Only I2C and PMU.
22:01.33mnemocthere is a simple captcha.. and even when bots register, very few write something...
22:01.57mnemochno: I have it modified to use cubieboards' dram_para
22:02.08mnemocnot sure if that matter
22:02.50mnemocTurl: do we really want to add the complexity (for humans) of a harder captcha?
22:03.20hnomnemoc, did anything work before you changed dram parameters?
22:03.55mnemochno: nope, it crashed once and the freeze in the second try
22:04.01mnemocthen*
22:04.44hnook. because I tried to jtag boot the SPL on my cubie and it hang very early in dram setup.
22:04.46Turlmnemoc: I don't care about the bots, as long as they don't spam all the things :)
22:05.04mnemocunless i've missed something, they don't spam
22:05.15hnobut did not spend much time with it.
22:05.31hnocan you send a pull request with your dram parameter cleanup?
22:06.50hnomnemoc, so why do they register
22:10.24mnemocsimple captcha is a plain text question
22:10.35mnemocsome are smart enough to answer it
22:12.24mnemochno: http://sprunge.us/CiaV <--- my diff..... but I don't know how to mange the config system to let that board_foo.c thing work properly :|
22:12.35mnemoci mean, integrated in Makefile
22:13.05mnemocappend ?diff to the url to get syntax highlighting
22:14.00mnemocor you want the pull request to have a place for discussing it?

22:29.32Turlmnemoc: can you add arbitrary plaintext questions?
22:29.57mnemocdon't know :|
22:30.01mnemoci guess so
22:30.30mnemocbut i'm kind of alergic to php so i do as little customization as possible
22:31.15Turlwe could add some tech questions so bots can't join as easy
22:34.15Turlsome trivial logic maybe, true xor true = ?
22:34.57Turlor "Is the sunxi family a x86 processor family?"
22:34.59mnemocyou have `sudo` powers :)

22:35.48mnemocbeware the wiki and all extensions are updated by cron
22:36.12Turlupdated by cron?
22:37.29mnemocthere is an update.sh there, which is called at *:42
22:37.46Marexhno: hey ;-)
22:37.51Marexhno: any news on the upstreaming ?
22:37.57Marexhno: -next is open for a while now
22:38.18mnemocTurl: it also updates the sitemap
22:38.31Turlheh 42 :)
22:39.21mnemoc:)

22:53.56hnoMarex, mainly SPL related stuff.
22:54.44Marexwhats up with SPL?
22:54.48Marexstill the memory init ?
22:55.13hnoNo, was missing PMU setup so CPU ran on wrong voltage and some other details.

22:57.37hnobasic PMU support landed tonight.
22:58.16Marexhno: heh
22:58.23Marexhno: I wish basic documentation would land ;-)
22:58.39hnothe PMU do have quite extensive documentation.
22:58.51Marexhno: ooh, that's good
22:59.27hnothe document for the specific chip is chnieese, but another chip in the family have english docs, and they share all registers & pins.
22:59.39hnohave not figured out how they differ yet.
23:03.19Marexhno: you really need to learn chineese :)
23:04.44hnotranslation engines and friends fill that gap sufficiently well for reading.
23:05.05hnowriting & communicating is more difficult.
23:07.28hnoMarex, how long is the merge window?
23:07.58Marexhno: I'd expect it open till november
23:09.08hnook. And then closed for a month or so?
23:10.48Marexhno: next release is scheduled for january
23:11.13Marexhno: but then, if you get basic support into current -next, you'll be able to patch it until -rc, which is around december
23:11.20hnomnemoc, seems sun5i also have GPS. Confusing.
23:12.17Marexhno: sun5i is A13 ?
23:12.27hnoMarex, understood.
23:12.50hnoMarex, A13 is in the sun5i family yes.
23:13.53mnemochno: i also wonder if they really removed g2d
23:14.20hnobased on
23:14.21hno?
23:14.42mnemocthe reserve is merely commented out
23:18.00mnemocalso the mixer processor is the best document part in the a10 manual.... and by the registers it seems to be what we call g2d... kind of makes me think if it's something they would suddenly consider unworthy
23:23.39hnomnemoc, g2d is erased from all sun5i headers & code. gps have slightly different & refined clock registers  in sun5i.
23:27.11hnoGPS is most likely there. But have no idicatoin g2d/mixer is kept. As mentioned current Android do not make use of it at all.
23:27.31hnoremember that the g2d memory reservation was commented out in the later sun4i code drops as well.
23:27.55mnemocright
23:29.09hnoit's a pity as it liits the interest in investing efforts into a g2d exa driver.
23:30.14mnemocyes
23:30.28hnoallwinner don't care as all their customers are happy with mali.
