Both native and cross compilation failed with Ubuntu Linaro Gcc 4.5.x and 4.6.x for an ARM/OMAP board

by AKS

Hi I was cross-compiling a Linux kernel 2.6.38 for a Gumstix Overo which is a tiny ARM (TI OMAP 35xx) based single board computer. I was using Linaro cross compiler (arm-linux-gnueabi-gcc) did not give an uImage that gets pass the Loading uImage. My console is ttyO2 and therefore it was not an issue. So I used Code Sourcey G++ Lite (64 bits version without ia32 library) and the kernel image uImage.bin built with the same configuration file (.config) but with different cross compiler can boot up to the stage that the kernel tries to mount ext3 partition on microSD card. So I suspect the package gcc-linux-arm-gnueabi has some bugs. I have a working 2.6.35 kernel (although I do not have the .config file with settings which I have used to build that) that was built with Linaro Gcc 4.3 or 4.4. I suspect the Linaro Gcc 4.5.x and above are giving me a problem. I used the Linaro media create tool with root file system and hardware pack but it also could not help me boot nor give me the right config file which I can use to cross compile a working kernel (that is booting kernel) for Overo computer. So I tried also native compilation using Linaro GCC 4.5 but it is not working. I wonder has anyone face the same issue like me, I think I am wrong somewhere (the last time I cross compile the kernel was pretty much straight forward and I dont remember I had to patch the kernel I fetched from a git repository. But I will be glad to hear who has faced similar problems like me. Any tips will be appreciated. Even better, I will be glad to learn where did you download (git fetch or git clone or wget or just http download), your tool chain, your workstation (my original laptop was 32 bits dual core DELL and now I am using a 64 bits Intel i7 so I am not sure which set up is biting me). Any tip or link will be appreciated. Sincerely Aung

Panda HDMI issue w/ 3.5-rc?

Hey Arnd, Rob, So after Arnd's help sorting a workaround for the mmc driver, I'm now trying to sort out the following HDMI failure I'm seeing w/ the current 3.5-rc with my Panda Board.

Perf record format portability

by Dmitry Antipov

Hello, are there any thoughts on how much of the perf.data is portable and how much it should be? I'm interesting in recording scheduler activity on one machine and then replaying on another. As I can see, replaying x86 perf.data on ARM doesn't work. At least, should it work with a small subset of recorded events (for example, sched:sched_switch, sched:sched_process_exit, sched:sched_process_fork, sched:sched_wakeup and sched:sched_migrate_task) on the same architecture? Thanks in advance, Dmitry

[PATCH] ARM: OMAP3/4: consolidate cpuidle Makefile

by Daniel Lezcano

The current Makefile compiles the cpuidle34xx.c and cpuidle44xx.c files even if the cpuidle option is not set in the kernel. This patch fixes this by creating a section in the Makefile where these files are compiled only if the CONFIG_CPU_IDLE option is set. This modification breaks an implicit dependency between CPU_IDLE and PM as they belong to the same block in the Makefile. This is fixed in the Kconfig by selecting explicitely PM is CPU_IDLE is set. The linux coding style recommend to use no-op functions in the headers when the subsystem is disabled instead of adding big section in C files. This patch fix this also.

[PATCH] cpuidle : use percpu cpuidle in the core code

by Daniel Lezcano

The usual cpuidle initialization routines are to register the driver, then register a cpuidle device per cpu. With the device's state count default initialization with the driver's state count, the code initialization remains mostly the same in the different drivers. We can then add a new function 'cpuidle_register' where we register the driver and the devices. These devices can be defined in a global static variable in cpuidle.c. We will be able to factor out and remove a lot of duplicate lines of code. As we still have some drivers, with different initialization routines, we keep 'cpuidle_register_driver' and 'cpuidle_register_device' as low level initialization routines to do some specific operations on the cpuidle devices.
