13:43.31LiidiaHi, can someone please help me with my unlocked S-ON HTC Wildfire S, that doesn't finish factory data reset?
14:11.45*** join/#htc-linux Cotulla (~myfakemai@109.205.253.11)
14:12.16Cotullahi
14:12.29Liidiahi
14:13.40fakkersveiki
14:18.00Cotullawhat's up?
14:22.16jonpry_heya
14:22.27jonpry_i think the problem is MPU
14:22.33Cotullahey
14:22.44Cotullawhy?
14:22.52jonpry_reads to 0x2880 0000 all zero
14:23.04jonpry_and all zero's is MPU effect
14:23.24*** join/#htc-linux Cotulla (~myfakemai@109.205.253.11)
14:23.27Cotullabad
14:23.32d3tul3how are you reading 0x2*
14:23.35Cotullaso u can use only TZ devices
14:23.36Cotulla?
14:23.38Cotulla*services
14:23.41jonpry_devmem
14:23.47d3tul3can devmem read that?
14:23.55Cotullabetter use ioremap
14:24.00jonpry_well try
14:24.05jonpry_i tried similar thing
14:24.12jonpry_also read 0x8da0 0000
14:24.31Liidiacan someone help me with my problem - an unlocked S-ON HTC Wildfire S, that doesn't finish factory data reset?
14:24.37jonpry_trustzone seems to enable MPU on that if it loads the image
14:25.10jonpry_Cotulla, don't you know some MPU tricks?
14:25.28d3tul38da reads 00
14:25.34jonpry_not good
14:25.51d3tul3i think devmem can only read mapped RAM
14:25.56jonpry_i was thinking of trying to use msm rotator to program it
14:25.58jonpry_nah
14:26.03d3tul3as in the stuff that shows up in cat /proc/iomem
14:26.07jonpry_it can read 0x2800 0000
14:26.20CotullaLiidia, how it doesn't finish?
14:26.27d3tul3oh right you are
14:26.33d3tul3is 8da somehow memblocked?
14:26.39jonpry_yeah
14:26.54Liidiai have waited for over 3 hours, it just won't finish, and if i take the battery out and boot it, it boots
14:27.08Cotullaboots till to OS?
14:27.08d3tul3so let's just make a new hole damnit....i mean we can use the same method to remove reserve memory that ramconsole does
14:27.17Cotullajonpry and TZ service wants signature?
14:27.18d3tul3i know for a fact that we can devmem read that chunk of memory
14:27.32jonpry_the hole is 8da0 isn't a real problem. if you boot unsigned image it doesn't get protected
14:27.42Liidiabut i deleted the google account i first linked the device with, so the phone isn't useful until i can factory reset it
14:27.46jonpry_but there is no booting without accessing dsp control at 2880 0000
14:28.15Liidiait boots till to os, yes i guess
14:30.00Liidiai once tried to root it, but it didn't work, and after that the factory reset never finishes
14:35.15*** join/#htc-linux Cotulla (~myfakemai@109.205.253.11)
14:35.24Cotullahm
14:35.34Liidiashould i relock it?
14:36.43Cotulladid u try to format it from HBOOT?
14:37.25Liidiayes, the same thing
14:37.42Liidiayou mean pushing volume down and power and then?
14:37.48CotullaI think yes
14:38.10Liidiayes, and i tried recvery as well
14:39.56jonpry_Cotulla, how can we defeat MPU?
14:41.45Cotullawe leaving ground I think
14:41.52Cotullahm
14:42.20Cotullamaybe try to access via some HW to turn it off
14:42.28jonpry_like DMA?
14:42.33Cotullayes
14:42.42jonpry_i don't even know where MPU is
14:42.58jonpry_is it possible to access DSPSS via DMA?
14:43.02Cotullait's in heaven
14:43.08Cotullacuz they named it XPU nowdays
14:43.10Cotulla:D
14:43.14jonpry_ah
14:43.29Cotullabut I don't have much experience with it on MSM8960
14:43.51Cotullabut I am afraid they can manage everything
14:43.58Cotullaincluding checking memory accesses in TZ
14:44.35LiidiaCotulla, is there any other thing i can try?
14:44.47Cotullais it working?
14:45.08Liidiais what working?
14:45.52Cotullahard reset from HBOOT
14:45.56Liidiait's not
14:46.00Cotullasame story?
14:46.01Liidiait doesn't finish
14:46.03Liidiayes
14:46.09Cotullamaybe just flash it
14:46.17Liidiahow?
14:46.21jonpry_so we need to hack trustzone?
14:46.37Cotullajonpry, maybe. like I said I don't have much experience with MSM8960 yet
14:47.03Cotullalooks and strokes QDS8250B
14:47.08Cotulla:D

15:11.58CotullaI am stopped on interrupt jonpry, detule
15:15.49jonpry_the controller?
15:17.42LiidiaCotulla, how do i run it?
15:18.24Cotullajonpry yes
15:18.39Cotullafirst level and second level
15:18.47Cotullafirst level is done by instructions
15:18.56Cotullasecond level - regular SIRC
15:20.09jonpry_so what is the problem?
15:24.38Cotullawhich one?
15:26.09jonprywith interrupts
15:26.40CotullaZZZZzzzz. . . . problem
15:26.47Cotulla:P
15:26.57Cotullain general just need implement and test it
15:27.11Cotullasome instructions are not really clear, but I think I got their usag
15:27.12Cotullausage
15:27.21Cotullaso in general nothing complex
15:27.31jonprynot like xpu?
15:27.55Cotullano xpu in 8250B
15:28.02Cotullayes
15:28.03Cotullait's like
15:28.06Cotullaint enable
15:28.11Cotullaint thread routing
15:28.18Cotullasoftware int
15:28.23Cotullaasknoledge and etc
15:28.28Cotullaand SIRC connected
15:28.31jonpryyeah
15:28.47jonprydid you ever run the compiled kernel?
15:28.53jonpryor just working on qMAGLDR?
15:29.05CotullaI worked under kernel
15:29.09Cotullabut never run it yet
15:29.15Cotullapage tables are still todo ^^
15:29.20Cotullaincluding head.S
15:29.22jonpryyeah
15:29.32Cotullaas well need to decide
15:29.35jonpryi wish i could run code
15:29.45Cotullasome implementation defined things
15:29.47Cotulla:(
15:29.59Cotullamaybe there is way to unlock
15:30.02Cotullaor is it done well
15:30.14jonpryi think if msm_rotator can access ebi i can probably take over
15:30.39Cotullawell it can be also checked
15:30.44Cotullabut try it
15:30.52jonprygotta program it
15:30.59Cotullacan u modify already running q6 code?
15:31.06Cotullaor it's protected also
15:31.20jonpryprotected if loaded via PAS

18:01.18d3tul3jonpry, you should be able to disable MSM_IOMMU
18:01.55d3tul3i mean i am running without it
18:02.19d3tul3not entirely sure why it's disabled in the CM defconfig
18:05.07Cotullait's bad
18:05.10Cotullawithout IOMMU
18:06.05d3tul3why?
18:06.27d3tul3when i enable iommu i lose service btw
18:06.52d3tul3pretty sure it's disabled in the stock 3.0 samsung kerenl
18:06.53d3tul3kernel
18:17.17Cotullacuz IOMMU is cool thing but complex
18:17.23Cotulladunno why it's disabled
