Hi Guys,
I'm trying to get our code running on an arago kernel from the 2.6.18
Montavista kernel.
We're running a DM365, and an MPEG2 Codec, but the same occurs with the
H264 codec too.
With CE_TRACE turned on shows the following:
ENCODE: Ch 0 InBuf 0 OutBuf 0
ENCODE: pOutBuf->virtAddr 0x46150000
@0x01365d41:[T:0x451aa490] ti.sdo.ce.video1.VIDENC1 - VIDENC1_process>
Enter (handle=0x29ddb0, inBufs=0x451a9be8, outBufs=0x451a9d4c,
inArgs=0x451a9d40, outArgs=0x451a9cb8)
@0x01365fb1:[T:0x451aa490] CV - VISA_enter(visa=0x29ddb0): algHandle =
0x29dde8
@0x01366127:[T:0x451aa490] ti.sdo.ce.alg.Algorithm - Algorithm_activate>
Enter(alg=0x29dde8)
@0x0136627c:[T:0x451aa490] ti.sdo.ce.osal.SemMP - Entered SemMP_pend>
sem[0x29d338] timeout[0xffffffff]
@0x013664aa:[T:0x451aa490] ti.sdo.ce.osal.SemMP - Leaving SemMP_pend>
sem[0x29d338] status[0]
@0x013666e7:[T:0x451aa490] ti.sdo.ce.alg.Algorithm - Algorithm_activate>
Exit
So I can see that the thread enters the VISA VIDENC1_process call into
the MPEG2 codec, but never exits.
I've traced this down and can see that it is waiting on an interrupt
from the co-processor
MPEG2 Encode :
#0 0x4062e27c in ioctl () from /lib/libc.so.6
#1 0x000e7314 in VICP_wait ()
#2 0x000e332c in HDVICPSYNC_wait ()
#3 0x000ddf44 in MPEG2VENC_TI_Encode ()
#4 0x0007c91c in VIDENC1_process ()
I traced this down as Interrupt 10 - and I have verified that the
interrupt is both enabled - and muxed correctly.
However the interrupt never arrives - - and we're always waiting on
VICP_wait. :(
Can anyone suggest any reasons why the codec would not be starting on
the new kernel ?
Would the memory maps of shared DTCM be different and prevent the
co-processor loading?
Would there be any other muxings that might prevent the co-processor
running?
I'm stuck - and can't get it to run - so just hoping someone might have
some ideas !
I don't think there's any way I can debug the state of the codec further
than the CE_TRACE - so I can't tell why the codec isn't running or
what's wrong with it.
Regards
Kieran
