System Memory Usage and Configuration Introduction This document describes i.MX android memory usage, layout and configuration for the entire system. Total DDR memory usage When i.MX Android is running, the DDR memory will be used by the following components: Linux Kernel reserved space, including: kernel text, data section and initrd kernel page tables       Normal zone space managed by kernel’s MM (high memory zone is also included) Used by application by brk() or malloc() in libc Used by kernel by mm api, like: kmalloc, dma_alloc, vmalloc       Reserved memory for GPU drivers, used by GPU libs, drivers Android surface view, normal surface buffers VPUs working buffer and bitstream (we allocate the VPU buffer from GPU driver to make a unify method of allocation) Reserved space for framebuffer BG triple buffers Framebuffer display are always required to have triple and large buffers       Memory layout The following diagram shows the default memory usage and layout on i.MX6Q/DL platform. Memory configuration According to different type of product and different hardware configurations (ddr size, screen resolution, camera), customer may do some configurations to the memory layout and usage to optimize their system. Some memory reservation can be configured by command line or modifying the code. The kernel reserved space cannot be adjusted. It is controlled by the kernel and the Normal zone size and it depends on the total DDR size and the reserved spaces. Reserved GPU memory size can be adjusted by adding "gpumem=" parameters in kernel commandline. It's size is highly depends on the screen resolution, the video stream decoding requirement and the camera resolution, fps. gpumem=<size>M Reserved memory size for BG (background) framebuffer can be configured by command line fbmem=<fb0 size>,<fb2 size>,<fb4 size>,<fb5 size> For example: If you have two display devices, one is XGA LVDS, the other is HDMI 1080p device (default 32bpp), you have to specify the BG buffer size for them: fbmem=10M,24M The size is calculated by xres*yres*bpp*3: 10M ~= 1024x768x4(32bpp)x3(triple buffer) 24M ~= 1920x1080x4(32bpp)x3(triple buffer)

In this article, some experiments are done to verify the capability of i.MX6DQ on video playback under different VPU clocks. 1. Preparation Board: i.MX6DQ SD Bitstream: 1080p sunflower with 40Mbps, it is considered as the toughest H264 clip. The original clip is copied 20 times to generate a new raw video (repeat 20 times of sun-flower clip) and then encapsulate into a mp4 container. This is to remove and minimize the influence of startup workload of gstreamer compared to vpu unit test. Kernels: Generate different kernel with different VPU clock setting: 270MHz, 298MHz, 329MHz, 352MHz, 382MHz. test setting: 1080p content decoding and display with 1080p device. (no resize) 2. Test command for VPU unit test and Gstreamer The tiled format video playback is faster than NV12 format, so in below experiment, we choose tiled format during video playback. Unit test command: (we set the frame rate -a 70, higher than 1080p 60fps HDMI refresh rate)     /unit_tests/mxc_vpu_test.out -D "-i /media/65a78bbd-1608-4d49-bca8-4e009cafac5e/sunflower_2B_2ref_WP_40Mbps.264 -f 2 -y 1 -a 70" Gstreamer command: (free run to get the highest playback speed)     gst-launch filesrc location=/media/65a78bbd-1608-4d49-bca8-4e009cafac5e/sunflower_2B_2ref_WP_40Mbps.mp4 typefind=true ! aiurdemux ! vpudec framedrop=false ! queue max-size-buffers=3 ! mfw_v4lsink sync=false 3. Video playback framerate measurement During test, we enter command "echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" to make sure the CPU always work at highest frequency, so that it can respond to any interrupt quickly. For each testing point with different VPU clock, we do 5 rounds of tests. The max and min values are removed, and the remaining 3 data are averaged to get the final playback framerate. #1 #2 #3 #4 #5 Min Max Avg Dec Playback Dec Playback Dec Playback Dec Playback Dec Playback Playback Playback Playback 270M unit test 57.8 57.3 57.81 57.04 57.78 57.3 57.87 56.15 57.91 55.4 55.4 57.3 56.83 GST 53.76 54.163 54.136 54.273 53.659 53.659 54.273 54.01967 298M unit test 60.97 58.37 60.98 58.55 60.97 57.8 60.94 58.07 60.98 58.65 57.8 58.65 58.33 GST 56.755 49.144 53.271 56.159 56.665 49.144 56.755 55.365 329M unit test 63.8 59.52 63.92 52.63 63.8 58.1 63.82 58.26 63.78 59.34 52.63 59.52 58.56667 GST 57.815 55.857 56.862 58.637 56.703 55.857 58.637 57.12667 352M unit test 65.79 59.63 65.78 59.68 65.78 59.65 66.16 49.21 65.93 57.67 49.21 59.68 58.98333 GST 58.668 59.103 56.419 58.08 58.312 56.419 59.103 58.35333 382M unit test 64.34 56.58 67.8 58.73 67.75 59.68 67.81 59.36 67.77 59.76 56.58 59.76 59.25667 GST 59.753 58.893 58.972 58.273 59.238 58.273 59.753 59.03433 Note: Dec column means the vpu decoding fps, while Playback column means overall playback fps. Some explanation: Why does the Gstreamer performance data still improve while unit test is more flat? On Gstreamer, there is a vpu wrapper which is used to make the vpu api more intuitive to be called. So at first, the overall GST playback performance is constrained by vpu (vpu dec 57.8 fps). And finally, as vpu decoding performance goes to higher than 60fps when vpu clock increases, the constraint becomes the display refresh rate 60fps. The video display overhead of Gstreamer is only about 1 fps, similar to unit test. Based on the test result, we can see that for 352MHz, the overall 1080p video playback on 1080p display can reach ~60fps. Or if time sharing by two pipelines with two displays, we can do 2 x 1080p @ 30fps video playback. However, this experiment is valid for 1080p video playback on 1080p display. If for interlaced clip and display with size not same as 1080p, the overall playback performance is limited by some postprocessing like de-interlacing and resize.

When streaming, if you want to play a streaming URL, it can be inconvenient if the browser cannot recognize the URL as a media stream and downloads the content rather than using Gallery to play it. To create this kind of media streaming, you need to write an apk to use VideoView to play the URL/media stream from the console. Here is the command of how to play a media file or network stream from console. Gingerbread am start -n com.cooliris.media/com.cooliris.media.MovieView -d "<URL>"       The URL can be file position or network stream URL, such as: you can play a local file by: am start -n com.cooliris.media/com.cooliris.media.MovieView -d "/mnt/sdcard/test.mp4" You can also play a http stream by: am start -n com.cooliris.media/com.cooliris.media.MovieView -d "http://v.iask.com/v_play_ipad.php?vid=76710932" Or play a rtsp stream by: am start -n com.cooliris.media/com.cooliris.media.MovieView -d "rtsp://10.0.2.1:554/stream" ICS am start -n com.android.gallery3d/com.android.gallery3d.app.MovieActivity -d "<URL>"        The URL has the same definition of Gingerbread.

Sometimes we need to use proxy to access network with Ethernet. Here are the steps for how to set proxy in Gingerbread and ICS. Gingerbread 1. Enable http proxy >  sqlite3 /data/data/com.android.providers.settings/databases/settings.db "INSERT INTO secure VALUES (99, 'http_proxy', 'wwwgate0.freescale.net:1080');" With this setting, you can access network for web browsing. If you want to play some http streaming content, you need to set a property for the player, > setprop rw.HTTP_PROXY http://wwwgate0-az.freescale.net:1080 2. Disable http proxy >  sqlite3 /data/data/com.android.providers.settings/databases/settings.db "delete from secure where name='http_proxy'" >  setprop rw.HTTP_PROXY "" ICS 1. Enable http proxy >  setprop net.proxy wwwgate0-az.freescale.net:1080 With this setting, you can access network for web browsing. If you want to play some http streaming content, you need to set a proxy property for the player, >  setprop rw.HTTP_PROXY http://wwwgate0-az.freescale.net:1080 2. Disable http proxy >  setprop net.proxy "" >  setprop rw.HTTP_PROXY ""
