QNX SDP 8.0.1 Kernel Update (Build GA8.0.1)

Date of this edition: August 16, 2024

This update includes a new implementation of the Virtual Memory Manager (VMM). It provides various performance improvements to the throughput of system memory allocation, notably when allocating large amounts of memory (such as at process creation). The new VMM's Application Programming Interface (API) is identical to the API of the VMM in previous SDP 8.0 releases.

This update includes the following packages found under Updates -> QNX Software Development Platform -> Microkernel:


Name	Package ID	Package internal version
QNX SDP 8.0 Kernel and libc	com.qnx.qnx800.target.microkernel.core	2.0.2.00388T202406131303L
QNX SDP 8.0 Microkernel - System Logger (slogger2)	com.qnx.qnx800.target.microkernel.slogger2	0.0.1.00388T202406131303L
QNX SDP 8.0 Microkernel - Tools	com.qnx.qnx800.target.microkernel.tools	0.0.1.00388T202406131303L

Installation notes
