Title:
Turn off non-zynqmp arch support
Status in linux-xilinx-zynqmp package in Ubuntu:
Fix Committed
Status in linux-xilinx-zynqmp source package in Jammy:
New
Bug description:
[ Impact ]
* This is an optimized kernel for zynqmp range of devices.
* Currently about 14% of kernel build is targeting non-zynqmp devices, which
is dead code unused in production
* This reduces kernel build time, kernel image & modules size, amount of
required firmware, and makes initrd smaller.
* This reduces peak memory usage on boot as well
* This will loose ability to execute this exact same kernel build on
non-zynqmp device, for benchmarking purposes generic kernel should be used
instead.
[ Test Plan ]
* Ensure newly produced kernel installs and boots on Ubuntu Server
and Ubuntu Core target devices without any loss of peripherals and
stock devices.
[ Where problems could occur ]
* This changes may limit ability to smoke-test this kernel on non-zynqmp
devices, if needed support for individual CPUs can be turned back on. Or
ideally any such testing should move to zynqmp devices. (examples of
potentially interesting things to turn back on upon request are QCOM APPLE
suppport for running this kernel on Arm Laptops for developer convenience)
* It is expected for KVM and QEMU to continue to work as both host and guest
[ Other Info ]
* Anything else you think is useful to include
* Anticipate questions from users, SRU, +1 maintenance, security teams and
the Technical Board
* and address these questions in advance
