why does Dm368 decode only 22 fps of h.264 file ?

I have just upgraded  my board DM368 arm clock from 297 Mhz to 432 Mhz . Then I test the demo program :

 ./decode -y 3 -v davincieffect.264 ,

shows only 22 fps:

ARM Load: 9% Video fps: 21 fps Video bit rate: 793 kbps Sound bit rate: 0 kbps Time: 00:00:04 Demo: Decode Display: 720P 60Hz Video Codec: H.264 HP Video Resolution: 1280x720 Sound Codec: N/A Sampling Freq: N/A

ARM Load: 7% Video fps: 22 fps Video bit rate: 1146 kbps Sound bit rate: 0 kbps Time: 00:00:06 Demo: Decode Display: 720P 60Hz Video Codec: H.264 HP Video Resolution: 1280x720 Sound Codec: N/A Sampling Freq: N/A

ARM Load: 10% Video fps: 22 fps Video bit rate: 1427 kbps Sound bit rate: 0 kbps Time: 00:00:07 Demo: Decode Display: 720P 60Hz Video Codec: H.264 HP Video Resolution: 1280x720 Sound Codec: N/A Sampling Freq: N/A

Both dvsdk_2_10_01_18 and dvsdk_dm368_4_02_00_06 show same output , only at 22 fps. I have not modified the driver and other else, everything is keeped along with dvsdk's original .

But at 297 Mhz  , It could decode fully at 30 fps.

Could anybody help me ?

Thanks

    As a clue , follow is an output of CE_DEBUG=3 ./decode -y3 -v davincieffect.264 on dvsdk2 . It seems there are a long time wait in Sem_pend or Sem_post.

    I have solved it by modifying  DVSDK_ROOT/dvsdk_dm368_4_02_00_06/psp/linux-2.6.32.17/drivers/media/video/davinci/davinci_platform.c .

    int davinci_enc_select_venc_clock(int clk){

      ......

      enable_hd_clk();
       __raw_writel(0x18, IO_ADDRESS(SYS_VPSS_CLKCTL));

    }
