Running powerdebug on Linaro Android causes kernel crash on Samsung Arndale Board

by Mohammad Merajul Islam Molla

Hello, I ran powerdebug on Linaro Android 14.04 with a custom kernel (config file attached). While exporting gpios, it seems to crash the kernel (detail log attached). I have some printfs, added in powerdebug export_free_gpios() function to assist during log taking. for (i = 0 ; i <= gpio_max ; i++) { char command[50] = ""; printf("exporting gpio: %d\n", i); sprintf(command, "echo %d > /sys/class/gpio/export", i); printf("command: %s\n", command); if ((ret=system(command)) < 0) printf("error: failed to export gpio-%d\n", i); printf("ret: %d\n", ret); } >From log, it looks like while trying to export gpio 8, kernel crash is happening - "Unable to handle kernel NULL pointer dereference at virtual address 00000044" (details in attached log) >From output of /sys/kernel/debug/gpio it looks like gpio 8 is not mapped to any device. Even manually trying to export gpio 8 causes the same crash. root@arndale:/ # cat /sys/kernel/debug/gpio GPIOs 0-7, GPA0: gpio-0 (s3c24xx-uart ) in hi gpio-1 (s3c24xx-uart ) in hi gpio-2 (s3c24xx-uart ) in lo gpio-3 (s3c24xx-uart ) in hi gpio-6 (i2c-bus ) in hi gpio-7 (i2c-bus ) in hi GPIOs 9-14, GPA1: gpio-9 (s3c24xx-uart ) in hi gpio-10 (s3c24xx-uart ) in hi gpio-11 (s3c24xx-uart ) in hi gpio-12 (s3c24xx-uart ) in hi gpio-13 (s3c24xx-uart ) in lo gpio-14 (s3c24xx-uart ) in hi GPIOs 16-23, GPA2: GPIOs 25-29, GPB0: GPIOs 31-35, GPB1: GPIOs 37-40, GPB2: GPIOs 42-45, GPB3: gpio-42 (i2c-bus ) in hi gpio-43 (i2c-bus ) in hi GPIOs 47-53, GPC0: gpio-47 (dw-mci-bus ) in lo gpio-48 (dw-mci-bus ) in hi gpio-50 (dw-mci-bus ) in hi gpio-51 (dw-mci-bus ) in hi gpio-52 (dw-mci-bus ) in hi gpio-53 (dw-mci-bus ) in hi GPIOs 55-58, GPC1: gpio-55 (dw-mci-bus ) in hi gpio-56 (dw-mci-bus ) in hi gpio-57 (dw-mci-bus ) in hi gpio-58 (dw-mci-bus ) in hi GPIOs 60-66, GPC2: GPIOs 68-74, GPC3: gpio-68 (dw-mci-bus ) in lo gpio-69 (dw-mci-bus ) in hi gpio-70 (dw-mci-cd ) in lo gpio-71 (dw-mci-bus ) in hi gpio-72 (dw-mci-bus ) in hi gpio-73 (dw-mci-bus ) in hi gpio-74 (dw-mci-bus ) in hi GPIOs 76-82, GPC4: GPIOs 84-87, GPD0: gpio-84 (s3c24xx-uart ) in lo gpio-85 (s3c24xx-uart ) in hi gpio-86 (s3c24xx-uart ) in lo gpio-87 (s3c24xx-uart ) in hi GPIOs 89-96, GPD1: GPIOs 98-103, GPY0: GPIOs 105-108, GPY1: GPIOs 110-115, GPY2: GPIOs 117-124, GPY3: GPIOs 126-133, GPY4: GPIOs 135-142, GPY5: GPIOs 144-151, GPY6: GPIOs 153-160, GPX0: GPIOs 162-169, GPX1: gpio-163 (VDD_33ON_2.8V ) out hi GPIOs 171-178, GPX2: gpio-174 (S5M8767 DS2 ) out lo gpio-175 (S5M8767 DS3 ) out lo gpio-176 (S5M8767 DS4 ) out lo GPIOs 180-187, GPX3: gpio-187 (HPD ) in lo GPIOs 189-196, GPE0: GPIOs 198-199, GPE1: GPIOs 201-204, GPF0: GPIOs 206-209, GPF1: GPIOs 211-218, GPG0: GPIOs 220-227, GPG1: GPIOs 229-230, GPG2: GPIOs 232-235, GPH0: GPIOs 237-244, GPH1: GPIOs 246-253, GPV0: GPIOs 255-262, GPV1: GPIOs 264-271, GPV2: GPIOs 273-280, GPV3: GPIOs 282-283, GPV4: GPIOs 285-291, GPZ: On the same board, running Linaro Saucy server does not cause any crash with powerdebug.

Is this expected? -- Thanks, -Meraj

Idlestat output question

by Salman Ahmed

Hello, Running top command with idlestat tool doesn't show any frequency information sometimes. I have run the program with the following command - #sudo idlestat --trace -t 5 -f /tmp/myoutput /usr/bin/top and it ended up with the following output where there is no frequency state information. The file "myoutput" doesn't have any cpu_frequency entry either. Total trace buffer: 153896 kB Log is 4.999488 secs long with 675 events clusterA@state hits total(us) avg(us) min(us) max(us) C6-SNB 163 4955450.00 30401.53 0.00 141946.00 cpu0@state hits total(us) avg(us) min(us) max(us) C1-SNB 1 912.00 912.00 912.00 912.00 C6-SNB 115 4996270.00 43445.83 67.00 211819.00 cpu0 wakeups name count irq040 eth0 50 cpu1@state hits total(us) avg(us) min(us) max(us) C1-SNB 3 10809.00 3603.00 27.00 10742.00 C6-SNB 62 4985746.00 80415.26 59.00 223952.00 cpu1 wakeups name count irq018 ata_piix 6 cpu2@state hits total(us) avg(us) min(us) max(us) C1-SNB 3 10800.00 3600.00 26.00 10745.00 C6-SNB 52 4986684.00 95897.77 5724.00 223957.00 cpu2 wakeups name count cpu3@state hits total(us) avg(us) min(us) max(us) C1-SNB 20 15123.00 756.15 121.00 10895.00 C6-SNB 47 4962591.00 105587.04 1.00 223950.00 cpu3 wakeups name count Does that mean processors spent all time in idle state and none in active state? -- Best Regards Salman Ahmed
