Linux/AM5728: GC320 memory configuration

Part Number: AM5728

Tool/software: Linux

Hi. we need various continuous memory of vivante(gc320) for GUI. total size is 80MB.

- 1280x720, 1920x1080, 1280x300, and so on. total size is 80MB.

As we trace gc320 drvier, we often notice allocating non-continuous memory for short continuous-memory as below it.

#define gcdDEFAULT_CONTIGUOUS_SIZE (4 << 20) at extra-drivers\ti-gc320-driver-5.0.11.p7\hal\os\linux\kernel\gc_hal_kernel_probe.c

If we increase gcdDEFAULT_CONTIGUOUS_SIZE -> 16MB or 32MB, we find decoding error(VPE memory). How do increase it ?

As other solution, we can consider TI OMAP or CMEM.

but, we have short memory for limiting TI OMAP memory(128MB), and then we don't use TI OMAP memory(it already three display, 3D GPU and IVA-HD).

If we CMEM ( we use CMEM_alloc2 API( internaly it return mmapd address(at cmem-mod-4.14.00.00+gitAUTOINC+b514a99ac4\src\cmem\api\cmem.c ) ) , this API is used VPE for deinterlace , it works very good ), vivante gc320 have error as below it.

status = gcoSURF_SetWindow(lpSurface->Surface, 0, 0, width, height); -> gckKERNEL_Dispatch ( gc_hal_kernel.c ) -> case gcvHAL_MAP_USER_MEMORY -> gckOS_MapUserMemory have error.

In order words, vivante gc320 driver don't support importing cmem when i use CMEM_alloc2 API .

I want to allocate continuous memory but non-continus memory at vivante gc320 . How can i work it ?

Hi Joonho,

Please check this example application on how to export CMEM allocated memory to Vivante driver -

https://git.ti.com/sitara-linux/video-graphics-test

Please check video_graphics_test.cpp, cmem_buf.cpp and gc320.cpp file. You will need enhanced QT eglfs_kms QPA to run this example application. The enhanced QPA along with this example application will be available in PLSDK 4.3 release scheduled end of 1Q, 2018.

Hi. Thank you for helping export CMEM allocated memory to Vivante driver.
we review this app source and then apply our source.
but, When Vivante driver flush cache, kernel die as below it. I think vivante driver don't access CMEM physical address.

our cmem confguration is as below it ( cmem(block id 2) works very good for VPE . )

arch/arm/boot/dts/am57xx-evm-cmem.dtsi

cmem_block_mem_1: cmem_block_mem@a0100000 {
reg = <0x0 0xa0100000 0x0 0x12800000>;
no-map;
status = "okay";
};
......

when we use CMEM_alloc2(2, 507904, &cmem_alloc_params); // align is 0x80 . w x h of surface = 1024 x 124
, our cmem log is as below it.

Hi Joonho,

There should not be any issue using CMEM memory with GC320 as the video-graphics-test example application that I pointed out earlier runs well with GC320. I do not see any kernel error with gcoSURF_SetWindow() API. GC320 driver has some restriction on buffer alignment and sizes. You may want to print those requirement and compare with actual values of the buffer you are passing. Check the function Gc320Obj::configure_surface() in the gc320.cpp file in video-graphics-test example application. There's check in the code before setting the buffer and window.

gcmONERROR(gcoSURF_GetAlignedSize(surf_ctx[i].surf,
&width,
&height,
&stride));

if((width != bo->m_width) || (height != bo->m_height) || ((uint32_t) stride != bo->m_stride)){
ERROR("Allocated Surf buffer width %d, height %d and stride %d doesn't meet GC320 aligned requirement on width %d, height %d and stride %d\n",
bo->m_width, bo->m_height, bo->m_stride, width, height, stride);
}

uint32_t p_adr_al;
gcmONERROR(gcoSURF_GetAlignment(gcvSURF_BITMAP, surf_format,
&p_adr_al,
NULL, //&p_x_al,
NULL //&p_y_al)
));

if((uint32_t)bo->m_buf[i] % p_adr_al){
ERROR("Buffer passed to GC320 doesn't meet the alignment requirement, GC320 alignment need is %x, received buffer with %x aligned address\n",
p_adr_al, ((uint32_t)bo->m_buf[i]%p_adr_al));
}

Also check the BufObj::BufObj() function in the cmem_buf.cpp file. Buffer size needs to be adjusted to take care of the width and height alignment requirement.

/* Vivante HAL needs 16 pixel alignment in width and 4 pixel alignment in
* height and hence adjust the buffer size accrodingly.
*/
uint32_t size = m_stride * ((m_height + 3) & ~3);

vivante_cmem.7z

Hi.

we attach full source(vivante_cmem.7z).

you can see #define OMK_CMEM_SUPPORT at galRunTest2.c

without OMK_CMEM_SUPPORT, it is work well with omap memory.

I compiled as make -f makefile.linux

our compile log is as following.

our board have error as following.
