This is due to the hierarchical nature of the functions. Also, while for example B calls A, B fills a data structure (on the stack) that it passes to A. A of course can get the same data structure from the user calling the interrupt interface. So, by switching to 32 bit mode and converting to 32 bit pointers early I could previously avoid a lot of headaches with the segment registers in 16 bit mode and reading the data from wherever they may be. Would you have any concerns about switching to 32 bit mode early, so that the interrupt handler and anything subsequent runs in 32 bit mode?
I can't say for sure what will make sense without seeing the code first, but it sounds okay to me.
I posted the TPM patches yesterday on the Qemu mailing list. It may take some time until TPM functionality becomes available in Qemu, but would you be willing to review the BIOS extensions even without being able to run them (for some time)? It's quite a chunk...
Yes - please break the patch up into chunks and send it to the list.
I mailed them today to firstname.lastname@example.org but didn't see them coming back or showing up on the webpage. I cc'ed the Qemu mailing list and there they are.
