I am experiencing a seemingly out-of-control memory consumption by the gl kernel modules when using DSS. When I noticed the system hung I stopped my application with gdb (running on the target) and the free memory reported by top was around 16mb (128mb total). I then ran rc.pvr restart and the free memory jumped back up to 78mb. I am using the v2.6.32_OMAPPSP_03.00.00.04 tagged linux from (http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary) along with the gfx_rel_es3.x drivers from OMAP35x_Graphics_SDK_setuplinux_3_01_00_02.bin along with a 640x480 lcd panel on custom OMAP3530CUS based hardware.
My question is what commands or type of commands cause the most memory allocation and how can this be controlled? Any hints as to what things can be tried or avoided would be greatly appreciated.
Thanks,
Ken
