description |
When building an upstream kernel using "make deb-pkg" and not any of the Ubuntu-specific kernel build methods (such as debian/rules binary-headers binary-generic), the resulting linux-image deb package includes a gzip-compressed kernel image (copied from Image.gz, not Image). When such a deb package is installed on an arm64 system (such as McDivitt) and flash-kernel is run, it always calls "mkimage" with "-C none", which results in a uImage that can't boot.
The attached patch adds a check to the mkimage_kernel() function in /usr/share/flash-kernel/functions to determine whether the kernel image is gzip-compressed or not, and calls "mkimage" with the appropriate "-C gzip" or "-C none" option. I have tested this patch on McDivitt, with both standard Ubuntu 3.13.0-37 and upstream 3.18-rc1 kernels, and it works for me. |
[Impact]
Ubuntu kernels >= hwe-y (4.8) will no longer boot on xgene/uboot systems. The image size appears to have outgrown the defined firmware region, and u-boot will error out with a checksum mismatch error. A solution for this is to start shipping a compressed kernel (Image.gz target). flash-kernel needs updating to detect a compressed kernel and set the appropriate uImage compression flag. Similarly, d-i needs updating because it does it's own uImage generation.
[Test Case]
Boot an hwe-y kernel on an xgene/uboot system (APM Mustang, HP ProLiant m400).
[Regression Risk]
The necessary code is in place and in-use for yakkety, and no issues have been discovered there. The SRU involves clean cherry-picks of that code for d-i & f-k. The kernel side needs to be modified to pull in the correct version of flash-kernel for xenial. |
