[yocto] [PATCH 06/12] meta-crownbay: update README

Wed Aug 17 09:51:07 PDT 2011

From: Tom Zanussi <tom.zanussi at intel.com>

With the new emgd-driver-bin recipe, the extensive instructions on how
to manually download and set up EMGD for the build are no longer
necessary.  Those instructions have been replaced with the simpler set
of instructions now needed to build crownbay with EMGD.

Changes to reflect the new image names and a couple other minor
cleanups are also included.

-The following subsections describe each option in detail.
+The crownbay BSP COMMERCIAL_LICENSE default setting causes the build
+to fail in order to prevent users from inadvertently creating and

+licenses.  Clearing the COMMERCIAL_LICENSE variable as shown above
+essentially tells the build system that you're OK with the fact that
+packages with non-free licenses such as EMGD will be installed in the
+image.
 
+Once you've done a build, you can examine the EMGD license(s) in the
+IEMGD_HEAD_Linux/License directory of the emgd-driver-bin work
+directory of the build.
 
-IIa Downloading and extracting the binaries using the EMGD Linux tarball
-------------------------------------------------------------------------
+Alternatively, you can examine the licenses before building by
+downloading the EMGD 1.8 Driver and looking at the licenses in the
+downloaded tarball.
 
-The first step of the process is to download the EMGD 1.6 Gold Driver.

 In the Download Now tab, select:
 
 IntelÂ® architecture-based product: Linux Tar Ball
-Operating System: MeeGo 1.0 IVI Linux (kernel 2.6.33.3, X.server 1.8.0)
+Operating System: MeeGo* 1.2 IVI Linux* (kernel 2.6.37, X.server 1.9, Mesa 7.9)
 
-That will give you a large tar file:
+That will give you a large .tgz file:
 
-Lin_EMGD_1_6_RC_1922.tar
+Lin_EMGD_1_8_RC_2032.tgz
 
 Extract the files in the tar file, which will in turn give you a
 directory named IEMGD_HEAD_Linux.
 
-The binaries are contained in an rpm file; you can extract the
-binaries from the rpm file using rpm2cpio and cpio:
-
-$ cd IEMGD_HEAD_Linux/MeeGo1.2
-$ rpm2cpio emgd-bin-1922-1.6.i586.rpm > emgd-bin-1922-1.6.i586.cpio
-$ mkdir extracted; cd extracted
-$ cpio -idv < ../poky-image-minimal-initramfs-emenlow.cpio
-
-Finally, you can copy the xorg-xserver binaries to the
-emgd-driver-bin-1.6 directory in the meta-crownbay layer:
-
-$ cp -a usr/lib meta-crownbay/recipes-graphics/xorg-xserver/emgd-driver-bin-1.6
-
-You also need to copy the IEMGD License.txt file to the same directory:
-
-$ cp IEMGD_HEAD_Linux/License/License.txt meta-crownbay/recipes/xorg-xserver/emgd-driver-bin-1.6
-
-At this point, you should be able to build meta-crownbay images as usual.
-

-IIb Extracting the binaries using the graphical ced application
----------------------------------------------------------------
-
-These steps require that you run a graphical application in Windows.
-Windows 7 was used for these instructions, but it shouldn't matter
-which version of Windows you use.
-
-The first step of the process is to download the EMGD 1.6 Gold Driver.
-Here is the current link to the URL which it can be downloaded from:
-
-http://edc.intel.com/Software/Downloads/EMGD/
-
-In the Download Now tab, select:
-
-IntelÂ® architecture-based product: Intel Atom Processor E6XX Series
-Operating System: MeeGo 1.0 IVI Linux (kernel 2.6.33.3, X.server 1.8.0)
-
-That will give you a large zip file:
-
-IEMGD_1_6_GOLD_1922.zip
-
-Extract the files in the zip file, which will in turn give you a large
-.exe file:
-
-IEMGD_1_6_GOLD_ALL_1922.exe
-
-Run IEMGD_1_6_GOLD_ALL_1922.exe to install, accept licenses, etc.
-
-If it says to install watcom, follow the instructions to do that.
-
-When the installation completes, an application named "emgd-ced" will
-be present in the install directory.  Double-click to run it.
-
-Select the menu item: New Configuration
-
-In the tabbed page, make the following selections and/or enter the
-specified data:
-
-Configuration File Name: myconfig
-Platform Chipset: Intel Atom Processor E6xx
-Port Devices: LVDS, sDVO
-
-Hit the 'Next' button.
+The applicable Licenses are contained in the License directory under
+IEMGD_HEAD_Linux.
 
-On the next tabbed page, make the following selections and/or enter
-the specified data:

-
-Package File Name: mypackage

-Target OS: Linux operating System
-
-Hit the 'Finish' button.
-
-Select the menu item: Generate Installation
-
-This will create the EMGD installation package:

-Generating EMGD installation...
-
-The installation package should now be under the 'workspace'
-subdirectory of the directory you installed to:
-
-workspace/installation/mypackage.pkg_installation/IEMGD_HEAD_Linux/IEMGD_HEAD_Linux.tgz
-
-This is the file you are interested in.  Copy it to your Poky build
-system, and uncompress/untar it:
-
-$ tar cvfz IEMGD_HEAD_Linux.tgz
-
-The binaries are contained in an rpm file; you can extract the
-binaries from the rpm file using rpm2cpio and cpio:
-
-$ cd IEMGD_HEAD_Linux/MeeGo1.2
-$ rpm2cpio emgd-bin-1922-1.6.i586.rpm > emgd-bin-1922-1.6.i586.cpio
-$ mkdir extracted; cd extracted
-$ cpio -idv < ../poky-image-minimal-initramfs-emenlow.cpio
-
-Finally, you can copy the xorg-xserver binaries to the
-emgd-driver-bin-1.6 directory in the meta-crownbay layer:
-
-$ cp -a usr/lib meta-crownbay/recipes-graphics/xorg-xserver/emgd-driver-bin-1.6
-
-You also need to copy the IEMGD License.txt file to the same directory:
-
-$ cp IEMGD_HEAD_Linux/License/License.txt meta-crownbay/recipes/xorg-xserver/emgd-driver-bin-1.6
-
-At this point, you should be able to build meta-crownbay images as usual.
