[meta-freescale] Request to integrate freescale i.mx 3.10.9-1.0.0 alpha release into dora branch of meta-fsl-arm

[Gonzalez, Alex]

Hi,

After reading this I decided to make a sanity check on the 3.10.9 kernel from the fsl-linux-2.6-imx/imx_3.10.9_1.0.0_alpha branch [1]. I am using a Sabre SD board.

With the default kernel configuration (imx_v6_v7_defconfig) and the sabre SD device tree (imx6q-sabresd.dts) I am seeing a crash on gpu_init. If I compile without GPU support it boots fine. Some debug shows the first register write in gckHARDWARE_Construct() is causing the crash:

    gcmkONERROR(gckOS_WriteRegisterEx(Os,                                       
                                      Core,                                     
                                      0x00000,                                  
                                      0x00000900));

This code hasn't changed much from 3.5 and it worked there.

Is anyone seeing this or is it only me?

Thanks,
Alex

Just to be clear.

3.0.35 is not going to be removed.

3.10.9-1.0.0_alpha will replace 3.5.7-1.0.0_alpha on the dora branch.

At some point in 2014 after community consensus and 3.10 is a GA kernel we hope to replace 3.0.35 with 3.10 but that is next year and we'll have this alpha, beta release to make sure it is acceptable to transition.   Unfortunately we don't have resources internally to test the community 3.0.35 kernel with non-kernel 3.10.9-1.0.0 packages.  I've done just a sanity test to make sure it works.

Components that are updated
- Multimedia upgraded to 3.0.9 and vpu wrapper upgraded to 1.0.40
- Graphics packages updated with Weston and window performance fixes on p12
- Kernel for 3.10.9
- uboot-imx - fixes and updates to support imx6slevk (yes I know this is forked)
- imx-test updated to fix build breaks on Yocto  
(note there is one epdc test that requires a name change to build on 3.0.35 - 
Otavio has this change).
- imx-lib has vpu removed so is back to LGPLv2 license
(this change was part of 3.0.35-4.1.0 release)
- imx-vpu created as separate component because it has different licensing.
(Daiane is working on mx53 similar solution)
- machine files updated for additional device trees for various pin configurations
- wayland-Weston, cogl and clutter updated for Weston-wayland builds

Most of the patches have been submitted and are undergoing review process.
