DM8168 Linux kernel memory utilization



Hi,

I am using 'ti-ezsdk_dm816x-evm_5_03_01_15'.

The default kernel config 'reserves' about 54MBytes of RAM in the Linux kernel early during boot.  This 'reservation' leaves too little free RAM available for us to run our application.

I have traced the majority of this allocation to the following kernel config line:

CONFIG_TI81XX_VPSS_VRAM_SIZE=50

questions:

1). Why is such a large amount of RAM being 'reserved' in the Linux kernel?

2). What feature or features utilize this memory?

3). Can I safely reduce the size of this allocation?

4). How can I eliminate this allocation altogether?

 

Thanks

Scott
