Size of UEFI system table

Post by PeterX »

Hi all,

I'm now working on UEFI applications. I searched the UEFI spec 2.8 and the UEFI page of OSdev.org wiki. Maybe I overlooked something. But I can't find infos about different CPU-bytesizes/bitwidths.

I only found: image type 0x8664 for x64 and subsystem 10 for UEFI application.

What I want to know: Are the entries in tables/structs of UEFI (like system table and boot services etc.) always the same size? Or does that vary on CPU bitwidth?

Greetings
Peter

Some of them are always the same size, others vary depending on the CPU. Check out table 5 in the current version of the UEFI spec (2.8 errata A).
