Developer Hitodama updated the PS4 native toolchain yesterday to add support for Kernel elf loading in the elf loader tool.

Typically, a process/binary running in kernel mode has more access than a “normal” process. This could mean access to more RAM in some cases, or functions that could help optimize speed, or simply being able to do things a normal process would not be able to (in the PSP world this included the possibility to spawn plugins on top of homebrews, for example)

The Native PS4 SDK and associated tools will only work if you have a PS4 running firmware 1.76 currently. This is not a limitation of the tools themselves, but running your own code on the PS4 today requires a combination of exploit + privilege escalation (kernel exploit). This combination today is limited by the only publicly know userland exploit, a Webkit exploit running on firmware 1.76.

Some users are leveraging the firmware 1.76 hack to run linux on their PS4, while other hackers are hard at work to run native tools and utilities through the exploits. The PS4 SDK is a critical piece, in both cases.
