pussuw opened a new pull request, #16519: URL: https://github.com/apache/nuttx/pull/16519
*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary This adds SMP support for iMX9.X CPUs. I also noticed a deadlock in the imx9 serial driver, which is patched here as well. To enable SMP for imx93 set the following configs: CONFIG_SMP=y CONFIG_SMP_NCPUS=2 CONFIG_IMX9_HAVE_ATF_FIRMWARE=y (this defaults to y so strictly not needed). ATF / TF-A is required (in bootloader / SPL) to boot the secondary CPU. ## Impact Impact is limited to the imx9 platform only. SMP support is added. No user, security, documentation etc. impact whatsoever; besides the aforementioned configs if SMP is wanted. ## Testing iMX93 board with an application with >100 processes and threads. -- This is an automated message from the Apache Git Service.
