Main Menu. Login Register. From these, I found out how to add a blank node from the Open Firmware bootloader. This adds a property with data and dlen being 0 no data , and name, nlen taken from the string literal ibm,aix-diagnostics.

Once I confirmed these commands added the proper node, I included them in my boot-command environmental variable on the QEMU command line:. With this property set, the diagnostics CD boots to the diagnostics application.

But I wanted a shell prompt. Instead, I installed xorriso, which does allow modifying ISO files in place. I ended up with the most convoluted method I can think of. I used xorriso to dump the location of this file inside the ISO :. I can then write a Python script that patches out the file at that location:.

That opcode decodes to slbmfev :. Indeed, the binary encoding of this instruction has one extra 1 bit, where the third argument for the instruction would be. However, this instruction only has two arguments, according to the disassemblers I found. I decided to work around this issue by commenting out the QEMU code that generates invalid instruction exceptions. This allowed me to enter the kernel debugger.

First of all, this shows that both slbmfev and slbmfee are affected by the Invalid Bits error. Could this be an instruction set extension?

Could this be an instruction set extension? This GNU binutils patch showed me what happened. POWER9 processors added an extra argument to slbmfev and slbmfee to allow these Segment Lookaside Buffer instructions to operate in the presence of a Radix page table similar to an x86 page table instead of the traditional PowerPC-styled page table. I created a kludge to allow QEMU to ignore the extra third argument.

With the patch, the kernel debugger works fine. Download the. Tutorial Trying out AIX takes about 20 minutes. I tested these instructions on macOS The full boot log can be found here. I know this!
