| 09:40.16 | zagibu | anyone experienced with GPIO pin programming on arm-compatibles? |
| 09:40.34 | Sphere | what about it? |
| 09:41.30 | zagibu | I have a strange problem, I'm using the macro GPSR to write on an out pin, which is connected to an in pin with registered interrupt handler |
| 09:42.06 | zagibu | the function that does the GPSR never returns before the interrupt stuff is done |
| 09:42.21 | zagibu | it basically waits on the interrupt to be handled... |
| 09:43.56 | Sphere | first of all, GPIO on ARM's are vendor specific |
| 09:44.18 | zagibu | it's an xscale pxa270 cpu |
| 09:45.38 | Sphere | so whats the problem? |
| 09:45.53 | Sphere | should it return? |
| 09:47.07 | zagibu | yeah, because that's the goal of the exercise...we have a test program that does a write, then a read which is artificially blocked, and in the interrupt handler, we unblock read again |
| 09:47.18 | zagibu | the goal is to measure the interrupt latency of the system |
| 09:48.12 | zagibu | at first we thought the interrupt was just handled very fast, faster than the user program can do the read, but whatever delay we introduce in the ISR handling, the write also waits as long |
| 09:48.18 | Sphere | blocked? |
| 09:48.27 | zagibu | with a waitqueue |
| 09:48.31 | Sphere | i would look into one of the headers what GPSR is doing |
| 09:48.44 | Sphere | are you running an operating system? |
| 09:52.09 | zagibu | yeah |
| 09:52.54 | zagibu | linux 2.6.28.10-CARME |
| 09:54.25 | Sphere | well i can't help you here |

| 17:02.26 | gratz|home | to save battery life, so when needed for vid playback and fancy stuff it would switch to the 9400m but when using word processor it whatever it'd be the lowered powered one |
