17:10.01jonprynot like assorted android patches?
17:10.31detuleno....qualcomm code is everywhere
17:10.53zeuskqualcomm.. they even have a football stadium...
17:11.34detulei think perhaps one way of doing this that might be easier is start with mach-msm from CA msm-3.4 and port the sgs3 sprint boardfile there
17:11.55jonpryor use rhod mach-msm
17:11.57detulethat way i can checkout code from ca that's already compiled against 3.4
17:12.25detuleyou realize that mach-msm these days looks nothing like ours right
17:12.55jonpryi think ours is better
17:14.08detuleours is better in the sense that it's the only functional 7x01 mach-msm out there
17:14.12jonprysomebody has got to make a mach-msm that supports 7k and 8k in a real way
17:14.28jonpryso i figure we start with the 7k that works and is understood
17:15.06zeuskis there any guide or documentation on how to start board support in a kernel in clean manner ?
17:15.30zeuski want to get 8k going in your 3.4 branch but this mmu is messing everything up..
17:15.39jonprythe msm board files shipping with mainline essentially do nothing
17:15.58jonpryand are good templates for basic support
17:16.28Alex[sp3dev]jonpry: how bad would it be to just split msm720x from mach-msm into a new mach?
17:16.40detulethat's  a lot of work to maintain both 7k and 8k especially since there are like 10 7k 3.4 users
17:17.01jonpryg1 will get on the bandwagon eventually
17:17.06Alex[sp3dev]detule: do you happen to know which baseband is in the sgs3?
17:17.45jonpryAlex[sp3dev], that might be the only practical solution and is what detule is doing
17:18.57detule[oliver@localhost sprint-sgs3]$ grep -r 'AMSS' arch/arm/configs/m2_spr_defconfig
17:18.58detuleCONFIG_MSM_AMSS_VERSION=6225
17:18.58detule# CONFIG_MSM_AMSS_VERSION_6210 is not set
17:18.58detule# CONFIG_MSM_AMSS_VERSION_6220 is not set
17:18.58detuleCONFIG_MSM_AMSS_VERSION_6225=y
17:18.58detuleCONFIG_AMSS_7X25_VERSION_2009=y
17:19.00detule# CONFIG_AMSS_7X25_VERSION_2008 is not set
17:20.11jonpryAlex[sp3dev] is your omap4 a .35?
17:20.23Alex[sp3dev]jonpry: 3.0
17:20.56jonpryurg. i have trouble with padconf not sticking on 35
17:21.17jonpryand it's ruining my day
17:21.35Alex[sp3dev]i've finished writing the firmware loader for galaxy s2 baseband and am finishing the one for nexus. i guess since samsung IPC protocol is the same, replicant ril will just work, I only need to implement the write/recv calls
17:21.57Alex[sp3dev]jonpry: which board? your prytab? maybe they're reset in some suspend routine?
17:22.06jonpryno on d3
17:22.35jonpryyeah i suspected power management. so i disabled off mode. no help
17:23.11Alex[sp3dev]i'd grep for the functions. that's likely in kernel because if it is done by, say, baseband, you're in trouble
17:23.32jonpryi can't find any code that seems to set padconf after boot except me
17:24.00jonprybut d3 has no real baseband. its a usb modem
17:24.14Alex[sp3dev]the (un)funny thing is that camera isn't working with uboot. probably some clock poop
17:24.43Alex[sp3dev]the galaxy nexus has mipi link to the modem. which is kind of like usb, but faster and simpler
17:25.19Alex[sp3dev]in terms of sw, of course. mipi is a parallel interface though
17:26.08Alex[sp3dev]wait, no. it's HSI - high-speed synchronous serial interface
17:26.31jonpryyeah mipi is display
17:27.38jonpryi kind of want to unioremap padconf control so the kernel will crash and i can figure out who is writing it
17:29.03jonprythis stuff is worse than haret
17:32.18Cotulla:D
17:32.20Alex[sp3dev]jonpry: HSI is a type of MIPI. there seem to be several types of mipi links - CSI for camera, DSI for display, HSI for modem and C2C
17:32.32CotullaI debugged one issue via such way, jonpry
17:34.35Alex[sp3dev]I had to debug uboot and linux on galaxy nexus that way. because I didn't want to disassemble the device and figure out jtag pinout. and probably that wouldn't work anyway because it's an HS device
17:35.04Cotullabut there no dynamic memory?
17:35.11Alex[sp3dev]btw, http://info.arteris.com/blog/bid/59433/Interchip-Connectivity-HSIC-UniPro-HSI-C2C-LLI-oh-my - seems a good description of mipi
17:35.25Alex[sp3dev]Cotulla: where is there no dynamic memory?
17:35.48Cotullain uboot I guess?
17:36.14Alex[sp3dev]Cotulla: I actually had several problems with memory corruption and I2C freeze, but solved that. As for memory, it sets up a one-to-one phys/virt mapping and all peripheral ports are open so it's easy to work with hardware
17:36.37Cotullayes
17:37.07Cotullashit my USB again died in PC. reboot X_x
17:37.18arrrghhhlol
17:37.21arrrghhhWindows... reboot reimage.
17:37.32Cotullau think linux doesn't need reboot for that?
17:37.41arrrghhhyou can usually cycle a service...
17:37.47Cotullabut what about drier?
17:37.50Cotullabut what about driver?
17:37.53arrrghhhi dunno what horrible things you're doing tho
17:38.02Cotullajust connected MAGLDR in TTY mode . . .
17:38.08Alex[sp3dev]Cotulla: depends. usually you can reload a module, but sometimes there are just bugs/broken algorithms and nothing except reboot helps
17:38.09arrrghhhyou can't unload and reload the driver in linux..?
17:38.17Cotullahm I think not?
17:38.21arrrghhhyes...
17:38.26arrrghhhc'mon now
17:38.26CotullaI saw a lot of drivers without proper deinit code
17:38.28Alex[sp3dev]arrrghhh: you can unless you compile it into kernel
17:38.39arrrghhhbut like Alex[sp3dev] said sometimes a reboot is the only option.
17:38.45Cotullayep
17:38.48Cotullaso I will reboot now
17:38.50arrrghhh:P
17:38.56Cotulla:(
17:39.09*** part/#htc-linux Cotulla (~myfakemai@nat100-255-205-109.tvoe.tv)
17:39.13Alex[sp3dev]I had a lot of problems with usb on 2.6.39 and 3.0 on my older laptop, but it was fixed later
17:40.45arrrghhhi must have windoze for work.  and it was just too cumbersome to do thru a vm.
17:40.45zeusknever had problem with usb, but nouveau gave a lot of problems, forced me to switch to nvidia's binary blobs
17:42.31*** join/#htc-linux Cotulla (~myfakemai@nat100-255-205-109.tvoe.tv)
17:42.33Alex[sp3dev]zeusk: well, usb was unstable on 3.0 and also there were bugs in scsi. so linux crashed just like some shitty freebsd back in 2006
17:42.38Cotullaback
17:43.51zeusko.o is your computer that fast cotulla or u using some magic tricks ?
17:44.04Alex[sp3dev]3 minutes is enough to reboot
17:44.09Alex[sp3dev]even to type passwords
17:44.17CotullaI get cap of tea also
17:44.33Alex[sp3dev]hope it was cup and not cap
17:44.36zeusklol
17:44.48Cotullayes it's fast
17:44.50zeuskcap of tea, leaks a lot
17:44.50Cotullacup yes
17:45.38zeuskhaving random lags on 6.2.8400
17:46.16zeuskand login screen has been turned into crap, only to find gnome is using win8 login screen as base for gnome3.6+
17:47.48Cotullastealers
17:48.45Alex[sp3dev]i am seriously worried about the mental health of people using fedora at work computers
17:48.57arrrghhhlol
17:49.00zeuskcuz of gnome alex ?
17:49.14Alex[sp3dev]zeusk: cause of Lennart Poettering and his amazing bullshit
17:49.32Alex[sp3dev]one piece of code is even more fucking awesome than the previous one
17:49.44Alex[sp3dev]pulseaudio, then journald and now - offline updates
17:49.50zeuskyep, puslse audio sucks
17:50.21arrrghhhzeroconf for avahi
17:50.23arrrghhhnot all bad :P
17:50.33Cotullaupdates by phone
17:50.38Cotullavia voice modulation
17:50.42Cotullawhich tell every byte
17:50.45zeuskbut even systemd is good on archlinux
17:50.51Cotullaand another side recognize that data stream
17:50.55Cotulla:D
17:51.06Cotullaas config option - language
17:52.23jonprycan i unmap just a segment of a large ioremap?
17:53.03arrrghhhyou're jonpry.  you can do whatever you want.
17:53.24jonpryjust make the kernel my beotch?
17:53.58Cotullajust fix it inside PTE
17:53.59Cotulladirectly
17:54.07Cotullaprimary PTE is located at the load address
17:54.13Cotullakernel base address + 0x4000
17:54.22Cotullain that crappy gap 0x8000
17:54.29Cotullajust go and unmap it
17:54.34Cotullaby hands
17:55.09zeuskby hands :o
17:55.14jonprywhat if its not a 4kb entry?
17:56.04jonpryomap has only one ioremap for all peripherals
17:56.56jonprymaybe i can unmap the whole freaking thing and then map the below and above
17:57.36Cotullahm
17:57.37Cotullamake own map
17:57.38Cotullawith 4K
17:57.41Cotullawith coarse
17:57.45Cotullareplace one by another
17:57.52CotullaI don't think anybody will notice that inside kernel
17:57.59Cotullaany evil creatures inside
17:58.04Cotullaor maybe use sections
18:04.37detuleyou guys know what this ramdump msm driver is for?
18:05.55detulei guess it's pretty self explanatory
