12:36 Z0l hello
12:37 dxtr Uhm
12:37 dxtr The kernels "make dtbs" doesn't generate any dtb files anymore. Why
12:37 dxtr ?
12:37 Z0l can somebody explain which kernel option enables the dev_dbg functions in the mxc hdmi driver?
12:38 rabeeh dxtr: which kernel?
12:38 dxtr rabeeh: 3.16
12:38 rabeeh sorry; i never used it
12:38 rabeeh maybe you want to pick the required dtbs?
12:38 dxtr I'm trying to Google and looking through documentation to see what's happened
12:38 dxtr rabeeh: how?
12:39 rabeeh make imx6q-cubox-i.dtb
12:39 rabeeh for example?
12:39 dxtr I use dove-cubox.dtb
12:40 dxtr And that worked
12:40 dxtr Thanks!
12:42 Z0l make dtbs never worked on 3.10 either
12:43 Z0l rabeeh: I've had a chat with jnettlet as well and I'm trying to pinpoint where the hdmi thing fails but it's still a bit complicated for me
12:44 dxtr Z0l: Really? Fascinating. I'm using 3.14 right now and it seems to work
12:45 Z0l dxtr: i tried it a couple days ago with that kernel and it didn't work, only if I explicitly told make which dtbs to build
12:45 dxtr Z0l: Oh well. Now I know!
12:45 dxtr Was it in 3.10 they removed it? I wanna see the commit log or something :)
12:49 rabeeh Z0l: which kernel?
12:49 Z0l 3.10.30
12:49 rabeeh what kind of failure do you see?
12:50 Z0l here's a full dmesg: http://pastebin.com/kfi7ukfg
12:50 Z0l and this is the detailed error: http://pastebin.com/P8EDZwGt
12:50 rabeeh did u try disable cpu idle?
12:51 Z0l yes, with a kernel parameter, but that didn't work
12:51 Z0l i can roll a kernel that doesn't have cpuidle at all, if you think that can be the solution
12:52 Z0l i also tried to compile a kernel without EDID support, but the compile ended with an error
12:53 rabeeh there were reports about kernel messages with "rcu_..."
12:53 rabeeh those were related to cpu idle framework
12:53 rabeeh jnettlet suggested to disable cpu idle for now
12:54 Z0l hmm, i thought those rcu_... functions were only responsible for catching the stall, not the root cause for it
12:55 Z0l also, during our conversation it turned out that the TV is not available via i2c
12:55 Z0l i only have bus 2
12:56 Z0l and this is how it looks like: http://pastebin.com/7FVnuei1
12:57 Z0l 0x68 was unreadable
12:58 rabeeh 0x68 is the RTC
12:58 Z0l ah, good to know that (I've also seen messages about the battery depleting, but hope that has nothing to do with it :))
12:58 rabeeh hdmi should be on 0x50 (edid)
13:00 Z0l on bus 1 or bus 2
13:00 Z0l ?
13:04 Z0l rabeeh: I've seen some dev_dbg functions in the mxc_hdmi.c, do you know how those can be enabled?
13:23 dxtr This is quite fascinating
13:24 dxtr With kernel 3.16 I get http://pastebin.com/DHqTfc5A while booting
13:24 dxtr And then it stalls there
13:25 dxtr https://github.com/dxtr/cubox/blob/master/buildkernel.sh <- This is the script I'm using to build the kernel
13:25 dxtr https://github.com/dxtr/cubox/blob/master/boot.txt <- This is my boot.txt
13:27 dxtr https://github.com/dxtr/cubox/blob/master/config-3.16 <- This is the config I'm using for 3.16
13:28 dxtr https://github.com/dxtr/cubox/blob/master/config <- This is the config for 3.14.4
13:28 dxtr Any ideas what could be wrong?
13:29 Z0l dxtr: why don't you pull a config from the 3.10.30 tree, make oldconfig and then make zImage instead of uImage?
13:29 dxtr Z0l: That's what I did once upon a time. Then I modified that config
13:29 Z0l I don't have the sources now, but I succesfully compiled 3.16 on Tuesday
13:30 Z0l dxtr: how come you ended up with uImage? That was 3.0.x times, no?
13:30 dxtr I've been using this cubox for years
13:30 dxtr And that's what it was back then so I've stuck with it
13:31 Z0l cubox or cubox-i?
13:31 dxtr Should I use zImage nowadays? CAn u-boot handle that?
13:31 dxtr cubox
13:31 Z0l my bad :(
13:31 Z0l i thought it's a cubox-i
13:31 Z0l please disregard then
13:32 dxtr rabeeh: Any ideas?
13:34 dxtr Can/should I upgrade u-boot so it can handle zImage? Or is my cubox too old for that? :p
13:34 dxtr And will that actually solve anything?
15:11 Tenkawa hi all
15:11 Tenkawa which kernel options does the i-ultra2 need to use usb and the onboard wifi?
15:11 rabeeh hi
15:13 Tenkawa oh.. theres one problem.. (usb was not in my kernel at all)
15:13 Tenkawa heh oops
15:16 Tenkawa ok.. recompiling a new kernel.. thanks though
23:41 Cuboxiii Hello all, anyone have some links to a good working version of Linux that'll run well on my cubox?
23:45 bencoh meh >_>
23:46 rabeeh Cuboxiii: which cubox are you using?
23:46 rabeeh iii? :)
