02:41.21detulejonpry, qcom offer you a job yet?
02:43.18jonprynot yet detule
02:43.45jonprythis talk of releasing the HVM is interesting
02:44.05jonpryi have serious doubts it will happen though
02:44.39jonpryeven if the engineer is serious, it's probably the same idea they had years ago
02:44.48detulemust be hard working there, if everything about the lawyers there is true
02:45.26jonprystupid lawyers
02:45.40jonprythis SMP is driving me nuts
02:46.23detulefork() still failing?
02:46.24jonpryinsane things start happening
02:46.32jonpryfork() is fixed
02:46.45jonpryafaict it's 100% with a single processor
02:46.57jonpryalthough Cotulla talks of some kind of slowdown
02:47.44detuleso how is smp failing?
02:48.03jonprythat isn't well understood
02:48.14jonprythings just stop making sense
02:48.48jonpryat some point it will either hang, have strange behavior with the TLB, or start causing double faults
02:49.02jonpryi think i understand the hang though
02:49.37detulehow does smp come into play are you guys onlin-ing another hexagon?
02:50.03jonpryi have it bringing up the second "core"
02:50.24detulewhat second core?
02:50.38jonpryso v2 is 6, v3 is quad
02:50.40jonpryi think
02:50.54jonpryno testing has been done beyond 2. but that is the word on the street
02:52.02jonpryit's not like a real core
02:52.19jonpryit's more like hyperthreading
02:52.48jonpryexcept not
02:53.34jonprylike on 6 core. if a single thread is running. it only will issue say 600mhz/6 = 100M instructions / second
02:54.09jonprythe pipeline is 6 clocks long. so the delay causes instructions to always appear to take 1 clock cycle
02:54.16jonprywith no delays and crud
02:55.47detuleis there any documentation on how they are virtualizing the core
02:56.11jonpryvirtualizing?
02:56.21detulehow they are presenting these 6 cores
02:56.41jonprythere isn't really any documentation for anything
02:56.46jonprybut we know how to start it
02:57.28jonpryevery core just has it's own register file
02:57.41jonpryand 1/6 clock cycles it gets access to the ALU
02:57.50detuleso the linux kernel actually sees 6 processors?
02:57.55jonpryyes
02:57.58jonpry2 for now
03:01.44jonpryprocessor <0x09> : 0
03:01.45jonprymodel name <0x09> : QDSP6V3
03:01.47jonpryBogoMips <0x09> : 200.00
03:01.47jonpryprocessor <0x09> : 1
03:01.47jonprymodel name <0x09> : QDSP6V3
03:01.47jonpryBogoMips <0x09> : 200.00
03:02.09jonprycat /proc/cpuinfo :)
03:02.10detulenice
03:02.23detuleconsole working?
03:02.28detule"Include mistic zuzu logger here" ? :)
03:02.46jonprymine is ram_console
03:03.32jonpryi don't have zuzu
03:15.14detulehave you heard of this MobiCore business
03:16.08jonpryno
03:17.29detuleMobiCore is an operating system being shipped with TZBSP
03:17.29detuleon msm chipsets. MobiCore consists of several components in
03:17.29detulethe secure world(TrustZone) and non-secure world(linux
03:17.29detulekernel, Android user space). The MobiCore driver
03:17.29detulecommunicates with the MobiCore kernel that exists in
03:17.32detuleTrustZone.
03:17.50jonpryhmm
03:17.56jonprycan we get it to load code?
03:18.16detulehttp://code.google.com/p/tee-mobicore-driver/ <--- source for the daemon
03:18.27detulei actually saw commits
03:18.33detulein the caf trees
03:18.35detuletoday
03:19.05jonprylike do the mobicore apps have to be signed somehow?
03:38.26detulei doubt this thing will make anyone's life easier
03:39.05jonprycould be
03:39.24jonpryi wonder what exactly a "high security operating system" is
03:40.25detulehttps://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=0CEIQFjAC&url=http%3A%2F%2Fwww.gi-de.com%2Fgd_media%2Fmedia%2Fdocuments%2Fcomplementary_material%2Fevents_1%2F04_STE_CARTES__Demo_Presentation.pdf&ei=_6E-UZ3cL4XL0AGDjYDADQ&usg=AFQjCNFFazRZtP606PQRpALzGZHEuvs4PQ&sig2=t0MPFNKYixT4a2VrXHN1zQ&bvm=bv.43287494,d.dmQ
03:41.08detulei don't know if this thing is actually loaded on current msm
03:41.16detuleexcept that this doc almost makes it sound like it is
03:41.16detulehttps://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&cad=rja&ved=0CEcQFjAD&url=http%3A%2F%2Ftee-mobicore-driver.googlecode.com%2Fgit-history%2F057a4f07d5e23916c1f353abe63d2afb5153dccd%2FV008%2FRelease_Notes.pdf&ei=_6E-UZ3cL4XL0AGDjYDADQ&usg=AFQjCNGOOsoKJCJeJhKtmpDCIVoiy9GNSg&sig2=JTRhK_onJTEAm_V_gy8XTw&bvm=bv.43287494,d.dmQ
03:44.00detuleg&d i think these guys are a no-joke outfit ... like they design passport security features for governments
03:45.07jonprylooks pretty serious
03:45.43jonpryeven if i could make a trustlet, it seems like breaking that mobicore could be a real hassle
03:48.45jonprythe easiest way to access qdsp on 8960 imho, is some kind of exploit in the q6 firmware itself
03:49.05jonprydoesn't seem like it would be written with a lot of security in mind

16:16.09Cotulladetule I heard u fixed our issue
16:16.14Cotullais it true?

16:20.03d3tul3Cotulla, you know I can't fix shit in terms of the type of issues you guys are dealing with
16:20.18d3tul3it looks like you are making stellar progress though
16:20.28Cotullasadly
16:24.14jonpryi dunno if any progress was made in the last many hours of hacking on it
16:24.24Cotullawho spelled?
16:24.32Cotullalooks to everybody
