Poll: When to use OVMF and Nt32?

Poll: When to use OVMF and Nt32?

[Palmer, Thomas]

EDK2 community,

                When developing/testing UEFI and you can easily choose between using OVMF and Nt32, which do you choose and why?  When is OVMF better/easier to use than Nt32 and vice versa?

                I ask because I am giving an internal presentation to our newer employees.  I've used one over the other for personal reasons, but I'd like to hear your thoughts and learn something new.

When developing pure UEFI application/driver that doesn't access real
HW, NT32 is the best environment because Visual Studio debugger can be used.

When developing application/driver that needs to access real HW,
OVMF or any other real HW platform should be used.

[Richardson, Brian]

Thomas:

I generally recommend NT32 when developing UEFI applications that don't have dependencies for any specific hardware design/architecture, and only rely on UEFI Boot Services.

OVMF is running on virtualized hardware, so it's better for the following scenarios...
* Testing boot to an operating system and/or UEFI Runtime services (supports call to Exit Boot Services)
* Testing applications that have a dependency on a specific hardware design/architecture

OVMF is also better for EDK II development under Linux, since NT32 only executes under Microsoft Windows environments.

Thanks ... br
