Do we have a memory footprint evaluation of ubuntu-desktop?

by Eric Miao

All, It was found that the ubuntu-desktop is a bit memory hungry on this i.MX53 QuickStart board. There is a large chunk of memory being reserved for the graphics/video drivers, and the memory size reserved has to consider the worst case. And we have to live with this before the unified memory allocator is available. I don't yet have a /proc/meminfo after system is right up, I'll get some statistics a bit later. However, I do want to know if we have some memory footprint evaluation of the existing ubuntu-desktop (we are using unity-2d)? And what can we do to improve on that? - eric

Notes & Actions: Linaro Graphics Working Group - Apr 13, 2011

by Alexandros Frantzis

Hi, notes and actions from our Wednesday graphics working group call are available on the wiki: + https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Notes/2011-04-13 Details about when and where of this meeting can be found here: + https://wiki.linaro.org/WorkingGroups/Middleware/Graphics#Weekly%20Public%2… Summary ======= * cairo-gles2 * Ported cairo-clock and cairogears to cairo-gles2. * Uploaded gles2 enabled packages for cairo, cairogears and cairo-clock to ppa:linaro-graphics-wg/ppa * Validated on OMAP4 (cairogears/cairoclock don't use any the repeat functionality missing in GL_IMG_texture_npot). * Benchmarks * Spandex unix-x11 branch merged in current upstream development tree. * Found issue with glcompbench rendering on ARM (coding error due to working with Mesa GLES spec violation - bug to be filed). * GLproxy - packages pushed to graphics working group ppa. * DRM/Mali - new Mali device driver drop (released 2011-04-01) integrated into git repository on git.linaro.org. * compiz work basically done (modulo some bug fixing), nux work underway. Thanks, -- - Alexandros
