The Linux Kernel version 6.12.67 has been officially released, introducing a range of enhancements focused on improving system performance and stability. This update addresses several specific issues, such as the handling of scenarios where no SRAT (System Resource Affinity Table) data is available for NUMA (Non-Uniform Memory Access) node configuration. Previously, users faced challenges when attempting to set up fake NUMA configurations; the new kernel version alleviates these problems, facilitating smoother setups in systems lacking chapNUMA information.
Another key fix pertains to the corruption of the Per-CPU Pool (PCP) when Symmetric Multi-Processing (SMP) is disabled. The kernel updates have refined the management of spinlocks and interrupts in these instances, promising more reliable behavior.
In terms of memory management, this release optimizes performance by batching page freeing operations and introducing a revised `refresh_cpu_vm_stats` function that now returns a boolean value indicating whether updates resulted in actual changes. This adjustment simplifies the process and makes it more efficient.
The release also rectifies additional bugs, including improvements to the `rockchip_usb2phy_probe` function, which now handles device interrupt request (IRQ) failures more gracefully to avoid double free errors, and a fix for clock leaks in the fsl-edma driver. This fix ensures that if resource allocation fails, the system can properly disable the clock and manage the power state, preventing resource wastage.
