Access physical memory in ESXi7.0

[NancyChiang]

Hi Sir,

I want to write a driver to access physical memory.

I have two method can work on LINUX system, 1. create driver to access, 2. use LINUX mmap function 

I saw this blog has open source code in ESXi 5.x, this can make me porting my driver inside and build the driver.

https://www.v-front.de/2013/03/how-to-build-device-drivers-for-esxi-5x.html

But our system is ESXi 7.0, is there any open source code let me build my driver.

If this way is no longer support on ESXi7.0, could you guide me another method to do this?

Thanks.
