The Yocto Project is open-source, so anyone can contribute. No matter what your contribution is (bug fixing or new metadata), contributions are sent through patches to a community list. Many eyes will look into your patch and at some point it is either rejected or accepted. Follow these steps to contribute: Make sure you have previously configured your personal info $ git config --global user.name "Your Name Here" $ git config --global user.email "your_email@example.com" Subscribed to the Freescale Yocto Project Mailing List Download `master` branches fsl-community-bsp $ repo init \   -u https://github.com/Freescale/fsl-community-bsp-platform \   -b master Update fsl-community-bsp $ repo sync Create local branches so your work is *not* done on master fsl-community-bsp $ repo start <branch name> --all Where `<branch name>` is any name you want to give to your local branch (e.g. `fix_uboot_recipe`, `new_gstreamer_recipe`, etc.) Make your changes in any Freescale related folder (e.g. sources/meta-fsl-arm). In case you modified a recipe (.bb) or include (.inc) file, do not forget to *bump* (increase the value by one) either the `PR` or `INC_PR` value Commit your changes using `git`. In this example we assume your change is on `meta-fsl-arm` folder sources/meta-fsl-arm $ git add <file 1> <file 2> sources/meta-fsl-arm $ git commit On the commit's log, the title must start with the filename change or introduced, then a brief description of the patch's goal, following with a long description. Make sure you follow the standards (type ` git log --pretty=oneline` to see previous commits) Create a patch sources/meta-fsl-arm $ git format-patch -s  --subject-prefix='<meta-fsl-arm][PATCH' -1 Where the last parameter (`-1`) indicate to patch last commit. In case you want to create patches for older commits, just indicate the correct index. If your patch is done in other folder, just make sure you change the `--subject-prefix` value. Send your patch or patches with git send-email --to meta-freescale@yoctoproject.org <patch> where `<patch>` is the file created by `git format-patch`. Keep track of patch's responses on the mailing list. In case you need to rework your patch, repeat the steps but this time the patch's subject changes to `--subject-prefix='<meta-fsl-*][PATCH v2'` Once your patch has been approved, you can delete your working branches fsl-community-bsp $ repo abandon <branch name>

This doc show how to use i.MX8QXP Display Controller GammaCor unit to tune gamma. HW: i.MX8QXP MEK board, HDMI monitor SW: i.MX Linux 4.14.98_2.2.0 BSP release, patch in this doc 1.Introduce gamma The gamma, gamma correction, gamma encoding, gamma compression , these words all related one kind operation , see wiki page of it: The device used for image capture/print/display follow this power-law. For example the camera captured image , to view this image on display device as good as original captured image : gamma encoding when camera saved sensor data to image file,  and  gamma decoding when that image file display on your PC LCD monitor. That is : 2. i.MX8QXP Display Controller Gamma Correction Unit The Gamma Correction unit position is located between Frame Gen unit and TCon unit.   More detail see below contents from i.MX8QXP RM: So GammaCor unit could be used as adjust display gamma , or brightness or contrast. To used it, need follow the steps at RM 15.9.2.4.4.8.3.   Something need to note: You need program 33 sample point value into the register, these sample point value range is from 0 to 1023. Note, first write is start sample point value , then the other is delta value: current sample point minus previous sample point value. You can use GammaCor unit on any channel of R/G/B. If you use normalized function f(x), the following formula should be used to clut[i = 0..32] = round( f(i * 32 / 1023) * 1023) 3. i.MX8QXP Linux device driver patch and test code Apply attached  patch 8qxp_dpu_gammacor_4.14.98_2.2.0.diff on Linux kernel. In the kernel patch, function dpu_gammacor_update, I choose not calculate delta value between each sample pint , let user space application calculate delta value and passed to kernel. Apply 8qxp-dpu-gammacor-modetst.diff on libdrm-imx, to get test application which is based on modetest.  Test app will read one greyscale image file 720P.rgb, put it under same folder of test application , calculate sample point value by pow function  , and calling drmModeCrtcSetGamma to pass related value to kernel,  next loop will change sample point value, and will see that greyscale image will changed on HDMI monitor. After system boot up, run below cmd to check result of test application systemctl stop weston ./gamma_show_rgba.out -P 29@32:1280x720@AB24 Reference: a>https://www.nxp.com/webapp/Download?colCode=IMX8DQXPRM b>https://www.nxp.com/webapp/Download?colCode=L4.14.98_2.2.0_MX8QXP&appType=license c> https://source.codeaurora.org/external/imx/libdrm-imx/ d> https://en.wikipedia.org/wiki/Gamma_correction

OpenGL OpenGL is the premier environment for developing portable, interactive 2D and 3D graphics applications. Since its introduction in 1992, OpenGL has become the industry's most widely used and supported 2D and 3D graphics application programming interface (API), bringing thousands of applications to a wide variety of computer platforms. OpenGL fosters innovation and speeds application development by incorporating a broad set of rendering, texture mapping, special effects, and other powerful visualization functions. Developers can leverage the power of OpenGL across all popular desktop and workstation platforms, ensuring wide application deployment. Source: http://www.opengl.org/about/overview/ On i.MX processors, OpenGL takes the advantage of GPU (Graphics Processing Unit) block to improve 3D performance.

NFS Network File System (NFS) is a network file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client computer to access files over a network as easily as if the network devices were attached to its local disks. The use of NFS makes the development work of user space applications easy and fast since all target root file system is located into host (PC) where the applications can be developed and crosscompiled to target system. The target system will use this file system located on host as if it is located on target. NFS service will be used to transfer the root file system from host to target. NFS resources are listed below: All Boards Deploy NFS All Boards NFS on Fedora NFS on Fedora All Boards NFS on Slackware NFS on Slackware All Boards NFS on Ubuntu NFS on Ubuntu

Some i.MX25 customers reported an issue for the GPT timer, when using 120MHz (240MHz UPLL divided 2) clock source as the GPT per_clk, the timer will not be increased all the time in free-run mode. If using 66.5MHz IPG clock and 133MHz PER clock as the clock source, there are no such issue. There are 4 test cases in the attached test code. Case 0: in CCM_MCR, set bit 5 as 0 for 133MHz HCLK as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b001 ipg_clk (66.5MHz). There is no issue, the GPT counter is fixed at 4 between old_cnt and new_cnt. Case 1: in CCM_MCR, set bit 5 as 0 for 133MHz HCLK as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b010 ipg_clk_highfreq (133MHz). There is no issue, the GPT counter is fixed at 8 between old_cnt and new_cnt. Case 2: in CCM_MCR, set bit 5 as 1 for 240MHz UPLL divided by 2 as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b001 ipg_clk (60MHz). There is no issue, the GPT counter is fixed at 4 between old_cnt and new_cnt. Case 3: in CCM_MCR, set bit 5 as 0 for 240MHz UPLL divided by 2 as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b010 ipg_clk_highfreq (120MHz). There is issue, the GPT counter is not a fixed value between old_cnt and new_cnt, and sometimes it will be negative. Count 9874: 4 old_cnt: 0x188849dc new_cnt: 0x188849e0 Count 9877: 12 old_cnt: 0x18918400 new_cnt: 0x1891840c Count 9915: 4 old_cnt: 0x189aea90 new_cnt: 0x189aea94 Count 9937: -12 old_cnt: 0x18a42458 new_cnt: 0x18a4244c Count 9967: 4 old_cnt: 0x18adb17c new_cnt: 0x18adb180 In fact, it is not an issue, when using UPLL as the GPT clock source, the maxim frequency should be 60MHz. That's why all other three test case is OK and it only failed on this case.

This patch implements (or exposes) routines to poll the imx uarts. The KGDB drivers need these methods to be implemented or the ttymxc driver is not sufficient. The synthetic CONFIG_CONSOLE_POLL value activates these routines (or CONFIG_SERIAL_MXC_CONSOLE for the polled write). There is still no poll routines in -855-ge067785, which is the September 2010 Linux release from Freescale.
