Hi, Ti,

I want to integrate H.264 DM36x Ver 2.0 Codec to into dvsdk2.10.00.18. The framework_components_2_24_01 and linuxutils_2_24_03 . I have seen H.264 DM36x Platinum Codec (ver 2.x) - Overview and features in WiKI of Ti.

1) When I run the encode.out. There was a error:

CMEM Error: init: major version mismatch between interface and driver.
CMEM Error: needs driver version 0x3000000, got 0x2300000

2) When I use linuxutils_2_25_02_08, have errors:

File /home/zhou/2approdvsdk/dvsdk_2_10_01_18/linuxutils_2_25_02_08/packages/ti/sdo/linuxutils/cmem/src/module/cmemk.c
allocated heap buffer 0xc6000000 of size 0x14e000
CMEM Range Overlaps Kernel Physical - allowing overlap
CMEM phys_start (0x1000) overlaps kernel (0x80000000 -> 0x84c00000)
cmemk initialized

edmak: Unknown symbol edma_free_slot
edmak: Unknown symbol edma_alloc_channel
edmak: Unknown symbol EDMA_CTLR
edmak: Unknown symbol edma_alloc_cont_slots
edmak: Unknown symbol edma_free_channel
edmak: Unknown symbol edma_clean_channel

How to deal with it? I want to H.264 DM36x Ver 2.0 Codec to into dvsdk2.10.00.18, Linux version 2.6.18.

waiting for your replay!

Star,

The EMDA symbols that are missing are for non-DM36x kernels. By default, edmak.ko builds for non-DM36x kernels. For DM36x kernels (LSP 2.10), a symbol needs to be defined.

In your linuxutils_02_25_02_08 release, you will need to rebuild edmak.ko with -DLSP_210. To do so, edit:
linuxutils_02_25_02_08/packages/ti/sdo/linuxutils/edma/src/module/Makefile
by changing the -ULSP_210 to -DLSP_210.

However, there is currently a bug where the EDMA_CTLR() macro is used outside of #ifndef LSP_210. In edmak.c, in the function release_channel(), the code at line 207 needs to change. Change:
    if (EDMA_CTLR(chan) == 0) {
        INIT_LIST_HEAD(&channels[channel].users);
        channels[channel].nParam = 0;
        channels[channel].isParam = 0;
    }
to:
#ifdef LSP_210
    INIT_LIST_HEAD(&channels[channel].users);
    channels[channel].nParam = 0;
    channels[channel].isParam = 0;
#else
    if (EDMA_CTLR(chan) == 0) {
        INIT_LIST_HEAD(&channels[channel].users);
        channels[channel].nParam = 0;
        channels[channel].isParam = 0;
    }
#endif

Regards,

- Rob
