Help for Foundation model

Hi all, Foundation model is closed source propertiary software, but i want to know how i can get more detailed and comprehensive technical support? I want to know the work procedure of boot wrapper. For example, make CROSS_COMPILE=aarch64-linux-gnu- BOOTARGS='"root=/dev/vda2 consolelog=9 rw co

[GIT PULL]: ll-interactive-gov-updates : Per policy governor instance

Hi Andrey, I have got some important updates for Android's Interactive Governor. These are already sent to Todd Poyner for inclusion into AOSP and we are awaiting a response. These changes are important for ARM big LITTLE platforms which want multiple instances of a governor to be available for a

Not trying to hijack the thread here but something like tinderboxes would be rather handy in terms of ensuring builds dont break http://en.wikipedia.org/wiki/Tinderbox_%28software%29 libreoffice uses them that way if something does break an email is sent out to the person who submitting the patch

Hi Nico, Liviu, Catalin, Do you expect there to also be cases where the PSCI interface may not be aware of all of the platform states? Eg. if you have an SOC, not all of the cstates and latencies are directly related to the ARM core.. Maybe you can have additional states and latencies accounting

Good article at LWN (well they are always good) referenced by the Linaro page you link to. The final comment is correct but not the complete answer. We also need determinism and no-interference for other reasons. Adaptive tick-less should also be useful when you have multiple threads on the sam

Interesting. But SCHED_DEADLINE doesn't depend on the PREEMPT_RT modifications? Are these solutions overlapping in some areas? For the relevant use cases, I don't know if strict CPU allocation (a fraction of the total CPU cycles) is needed. Instead these apps (we are talking legacy SW) are des

Ola, Are you concerned with lower system-wide scheduling latency or with predictable response times for a particular task? I believe SCHED_DEADLINE with help with the later. /Amit On Mon, May 20, 2013 at 1:10 PM, Ola Liljedahl wrote: > In my experience, networking is moving away from realtime

RE: Deadline scheduler inclusion in linux-linaro?

In my experience, networking is moving away from realtime scheduling (and thus RTOS’es). There are some lingering requirements for some of the processing in the wireless stack but the main difficulty here is getting the scheduling latency down to acceptable levels, e.g. five microseconds or so.
