Confusion Regarding Powerdebug Sensors Info on i386

by Mohammad Merajul Islam Molla

Hello, I ran powerdebug on i386 (ubuntu 13.04) and it seems its outputting wrong information in "Sensors" info page. Suspects are colored blue below - # sudo ./powerdebug PowerDebug 0.7.2 Clocks Regulators Sensors Gpio Name Value coretemp temp1_crit_alarm 0.0 temp3_input 34.0 temp3_label 34.0 ----> This seems incorrect temp2_crit_alarm 0.0 temp1_crit 99.0 temp2_crit 99.0 temp3_crit 99.0 temp4_crit 99.0 temp5_crit 99.0 temp4_input 23.0 temp4_label 23.0 ----> This seems incorrect temp3_crit_alarm 0.0 temp4_crit_alarm 0.0 temp5_input 34.0 temp5_label 34.0 ----> This seems incorrect temp5_crit_alarm 0.0 temp1_input 34.0 temp1_label 34.0 ----> This seems incorrect temp1_max 80.0 temp2_max 80.0 temp3_max 80.0 temp4_max 80.0 temp5_max 80.0 temp2_input 28.0 temp2_label 28.0 ----> This seems incorrect The contents of these files are not any legal integer value as expected - # cat temp*_label Physical id 0 Core 0 Core 1 Core 2 Core 3 The problem I think is in the below code in utils.c/file_read_value()- ret = fscanf(file, format, value) == EOF ? -1 : 0; We are comparing with EOF. In this case fscanf is returning zero. So this check passes and returns success. So old value is retained in "value" from previous read. A simple fix would be to change the line to - ret = fscanf(file, format, value) <= 0 ? -1 : 0; Would you care to check? diff --git a/utils.c b/utils.c index 4d4b780..bfe2ba3 100644 --- a/utils.c +++ b/utils.c @@ -46,7 +46,7 @@ int file_read_value(const char *path, const char *name, goto out_free; } - ret = fscanf(file, format, value) == EOF ? -1 : 0; + ret = fscanf(file, format, value) <= 0 ? -1 : 0; fclose(file); out_free: -- Thanks, -Meraj

Foundation model stays in idle

by Jean Pihet

Hi! I wanted to ask for help on the Foundation model which becomes really slow after a while, to the point where it is not usable anymore. Quite often I have to kill the model (Ctrl-C) and restart it, with corrupted files on the root FS. I am using the latest Foundation model, kernel image, instructions from the release page [1] but it also happens with my own mainline kernel. [1] http://releases.linaro.org/latest/openembedded/aarch64/ Symptoms and observations: - after a few minutes the system looks like it is hanging but still reacts on ping, the shell is still active but everything related to the filesystem hangs (top, free, compiler etc.), - there is no sign of memory exhaustion or abnormal caching as seen from a recurrent 'free'. 90% of the memory is free, - the problem arrives faster when working in an NFS mounted dir, - on the visualization webpage (localhost:2001) all cores are idle all the time and the number of instructions executed is really low (about 30K insts/s), - the exact same setup used to work fine until my machine crashed (lost the home dir completely), now the problems happens with both AXF and UEFI based boot. Is there something you already observed, is there a cure (kernel or root FS config etc.)? Here is the startup script: # cat boot_fvp_uefi.sh #!/bin/sh # Start Foundation model >= 5206 from the Image and img images pidof Foundation_v8 > /dev/null && echo -n 'Foundation_v8 already running' && exit IMAGE=vexpress64-openembedded_lamp-armv8-gcc-4.8_20140417-630.img exec Foundation_v8 \ --cores=2 \ --network bridged \ --block-device $IMAGE \ --no-secure-memory \ --visualization \ --gicv3 \ --data=bl1.bin@0x0 \ --data=uefi_fvp-base.bin@0x8000000 Any feedback welcome! Cheers, Jean

Prebuilt Linaro 2014.04 arm-linux-gnueabihf: cannot find /lib/ld-linux-armhf.so.3

Hi, I've been having this issue with latest binary Linaro 2014.04 toolchain from http://releases.linaro.org/14.04/components/toolchain/binaries/gcc-linaro-a… It comes with own sysroot, but linker fails to locate /lib/ld-linux-armhf.so.3 $ make arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o nvs.o nvs.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o misc_cmds.o misc_cmds.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o calibrator.o calibrator.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o plt.o plt.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o wl18xx_plt.o wl18xx_plt.c arm-linux-gnueabihf-gcc -I/tmp/include/libnl3/ -DCONFIG_LIBNL32 -c -o ini.o ini.c arm-linux-gnueabihf-gcc -L/tmp/lib/ nvs.o misc_cmds.o calibrator.o plt.o wl18xx_plt.o ini.o -lm -lnl-3 -lnl-genl-3 -o calibrator /opt/linaro-2014.04/bin/../lib/gcc/arm-linux-gnueabihf/4.8.3/../../../../arm-linux-gnueabihf/bin/ld: cannot find /lib/ld-linux-armhf.so.3 collect2: error: ld returned 1 exit status Makefile:26: recipe for target 'all' failed make: *** [all] Error 1 And when I pass my own sysroot, it works fine. Is it supposed to work as a standalone toolchain with its own bundled sysroot? Thanks. -- Denys
