| 13:37.10 | ccole | Is there a CPU load meter program for Linux that will show the load imposed by each individual process graphically? |
| 13:42.26 | wmat | ccole: google for graphical top frontend |
| 13:43.59 | *** join/#elinux pirho (debian-tor@gateway/tor-sasl/pirho) |
| 14:19.30 | ccole | @wmat: All the GUI process graphs I have seen either graph the per-cpu load, or show each individual process %cpu used. I would like to find something that plots the %cpu used per process, in a similar fashion as the composite cpu load is plotted.. Of course, there would be probably 50-100 traces to plot.. but I imagine that this would make for a great tool.. |
| 14:20.38 | ccole | @wmat: The closest thing I can find is a GUI that simply lists the processes, and shows a cpu % each process uses. No per-process plot vs. time. |

| 17:34.15 | robint91 | I have a problme |
| 17:35.06 | robint91 | I can't get linux to say anything interresting throught the console |
| 17:35.37 | robint91 | It just hangs at Uncompressing Linux... done, booting the kernel. |
| 17:41.59 | robint91 | it is on an AT91RM9200 |
| 17:42.43 | roxfan | you have jtag? |
| 17:48.02 | robint91 | jep |
| 17:48.04 | robint91 | openocd |
| 17:50.24 | roxfan | then connect it and see where it's hanging |
| 17:59.47 | ccole | robint91: That happened to me last week when I discovered I had half the RAM I thought I had ;) |
| 18:00.01 | ccole | robint91: Also tun on DEBUG_LL in the kernel dev options |
| 18:00.51 | robint91 | okay |
| 18:01.21 | ccole | robint91: Put your compressed kernel high up in memory, then jump to the decompressor entry point.. but make sure you dont put the kernel so high that it wraps around to the beginning of memory ;) |
| 18:02.00 | robint91 | other larger kernels boot |
| 18:02.19 | robint91 | The old ram image of 8MiB boot prefect |
| 18:02.29 | robint91 | but not my new kernel image |
| 18:03.03 | robint91 | DEBUG_LL already on |
| 18:17.00 | robint91 | Isn't there a function that prints something on the console |
| 18:17.10 | robint91 | when the kernel starts to boot |
| 18:28.35 | ccole | yes look in head.S |
| 18:29.04 | ccole | also make sure the right ttyC is selected for early debug messages and console messages |
| 18:29.16 | ccole | err, ttySn |
| 18:30.52 | ccole | So start looking at arch/arm/kernel/head.S, around line 78 or so ("Kernel startup entry point"). Looks like your decomressor worked fine. It calls this entry ehdn it's done. |
