[RFC 0/2] psci: Add core wakeup operation

by Abel Vesa

This is more like a workaround for platforms like i.MX8MQ that have an issue related to the wake_request GIC signal integration. See E11171 here: https://www.nxp.com/docs/en/errata/IMX8MDQLQ_0N14W.pdf The workaround mentioned in the document has the dissadvantage of waking up all the sleeping cores instead of just one. This patchset adds another psci op for core 'poking' (waking up). On i.MX8MQ, the plat specific implementation writes the corresponding bits in GPC to wake up independently each core.

Does CMAKE support configuration system as well ? Another factor to consider is the familiarity of the build system with the community, and we think Kbuild would rank high on that.

Has CMAKE been considered ? CMAKE should work equally well on windows(visual studio and Cygwin) and linux. You can create a new build system around CMAKE while keeping the current Makefile system alive, and deprecate it later, once the CMAKE based build system is stable. -Raghu On Dec 13, 2018, at 04:00 AM, tf-a-request(a)lists.trustedfirmware.org wrote: Send TF-A mailing list submissions to tf-a(a)lists.trustedfirmware.org To subscribe or unsubscribe via the World Wide Web, visit https://lists.trustedfirmware.org/mailman/listinfo/tf-a or, via email, send a message with subject or body 'help' to tf-a-request(a)lists.trustedfirmware.org You can reach the person managing the list at tf-a-owner(a)lists.trustedfirmware.org When replying, please edit your Subject line so it is more specific than "Re: Contents of TF-A digest..."

It is unfit for the amount of options and dependencies of said options, and adding new features is now an effort of trying to add the new feature while not breaking the rest of the code. There is another problem. When the firmware is compiled with, say, OPTION=1, if it is recompiled with OPTION=0 without cleaning first, nothing will be rebuilt. We have had several discussions about this internally and we have decided to migrate to Kbuild/Kconfig, the build system used by the Linux kernel. There are already some projects using it, like U-Boot or Zephyr RTOS. We are starting the work related to this migration, and our intention is to migrate upstream platforms to this new build system.
