Hey babs76er,

im working on this problem but dont have a solution atm. Ill post here as soon as i know something new.

Kind regards,

Christian

Christian,

Sounds good. I've started debugging this today as well. It appears to be an indexing issue / pointer in drivers/video/omap2/dsscomp/gralloc.c. I've added some debug code. During normal display operation (HDMI) the number of managers is always 1. Once you've authenticated on wifi, num_mgrs = 2 and the second call to dsscomp_set_mgr() fails because comp[ch] = NULL. That's as far as I've got. 

Output of console:

Christian & Babs,

Can you try the latest release 5AJ.1.5.1 and see whether the issue which you're seeing is still reproducible.

Rakesh,

I've flashed the 5AJ.1.5.1 binaries and I have the same crash issue on the uevm5432.  Here is an output from the console:

Rakesh,

Basically, in gralloc.c, function dsscomp_gralloc_queue(), the number of cdev displays is 1 because the board file only defines one display, the HDMI. Therefore the following code will ultimately cause the NULL pointer:

/* mark managers we are using */
for (i = 0; i < d->num_mgrs; i++) {
/* verify display is valid & connected, ignore if not */
if (d->mgrs[i].ix >= cdev->num_displays)
{
printk(KERN_INFO "%s: WARNING: d->mgrs[%d].ix(%d) >= cdev->num_displays(%d)\n",
__func__, i, d->mgrs[i].ix, cdev->num_displays);
continue;
}

Since cdev->num_displays is 1, the code checks out of the for loop and does not provide a "channel" for wifi display. Therefore the call to dsscomp_set_mgr() will cause the kernel panic because comp[ch] argument is bad.  

I don't totally understand the interactions between DSS COMP and the Wifi Display, but its looking for a second display that does not exist in the cdev definition. Should there be a Wifi Display defined in the board file (via omap_dss_device)?

Have you solved such problems? I met the same issue on Blaze tablet.

I have not been able to solve this issue. I'm waiting for some help from TI, hopefully. 

I suppost this issue is in hwc module in Android. As far as I know, some phones of which using OMAP solutions work fine with Wifi display. BTW, have you compiled the HDMI DSS interface in your kernel?
