[PATCH] rt-app: Add IO-bounded and memory-bounded events

by pi-cheng.chen

Add 2 new kind of event for running a memory or a io bounded load. "mem" name for a load is memory bounded, and "iorun" name for a load is io bounded. The default file to be written to create the load is /dev/null and the device/file could be specified with "io_device" key in "global" section. E.g. "tasks" : { "thread0" : { "sleep" : 1000, "run" : 100, "mem" : 1000, "sleep" 10000, "iorun" : 1000 } }, "global" : { "io_device" : "/dev/ttyS0" } Signed-off-by: pi-cheng.chen <pi-cheng.chen(a)linaro.org> --- src/rt-app.c | 74 +++++++++++++++++++++++++++++++++++++++++++++++ src/rt-app.h | 2 ++ src/rt-app_parse_config.c | 23 +++++++++++++++ src/rt-app_types.h | 4 +++ 4 files changed, 103 insertions(+) diff --git a/src/rt-app.c b/src/rt-app.c index 3cd601d..13f72e4 100644 --- a/src/rt-app.c +++ b/src/rt-app.c @@ -33,6 +33,8 @@ static volatile int continue_running;

Build LSK 3.14 kernel with android-toolchain

by Shawn Guo

Hi all, Is it a valid or supported use case to build LSK 3.14 kernel with android-toolchain? I can build a LSK 3.14 kernel with Linux toolchain gcc-linaro-arm-none-eabi-4.9-2014.09, which boots fine on my board. When I build the same kernel with android-toolchain-eabi-4.9-2014.09-x86, the kernel can be built out successfully, but it fails to boot on the board at very early stage with only uncompressing message shown up like below. Uncompressing Linux... done, booting the kernel. And it's not a LSK 3.14 specific problem, I tried to build mainline 3.10, 3.14 and 3.18-rc4 with the android-toolchain, and they all failed to boot. I need some help to understand if it's a valid use case at all, before I try to looking into the problem. Thanks, Shawn

There are still few issues: - I thought it will look like this: [RT-APP][PATCH] Add IO-bounded and memory-bounded events @Amit ? Same is true for all other utilities like idlestat as well.. The place where you have put rt-app now is reserved for the module within the repo to which the patch belongs. Not sure if rt-app repo has need of such modules though. - There should have been somebody in the --to field, whom you want to review your patches. You don't have to resend it now.. :)
