Title:
AWS: enable FPGA support in amd64 AWS kernels
Status in linux-aws package in Ubuntu:
Fix Released
Status in linux-aws source package in Focal:
Fix Committed
Bug description:
CONFIG_FPGA needs to be enabled in linux-aws amd64 kernels (thereby
supplying the fpga-mgr module), to support the AWS F1 instance type.
Delivering the fpga-mgr module via the 'linux-modules-extras' package
is acceptable.
This config change only needs to be specifically applied to linux-
aws/focal, since:
linux-aws/bionic (aws-5.4) will pick it up from focal;
linux-aws-groovy already has it enabled;
linux-aws-xenial cannot support F1 anyway.
----------------------
[Impact]
* Since fpga-mgr is inadvertently omitted from linux-aws, use of the
F1 instance type requires the user to manually install linux-virtual
or linux-generic, which is an annoyance.
* This patch just enables the module in linux-aws as we do for other
kernels.
* Fwiw, fpga-mgr is actually (needlessly) already enabled for linux-
aws/arm64 but disabled for linux-aws/amd64 (where its needed for F1).
[Test Case]
* Install the linux-modules-extras package; modprobe fpga-mgr.
[Regression Potential]
* None.
