GDT refresh
Posted: Tue Jul 19, 2005 11:00 pm
Hi, I have one simple question:
If i used tss with one of GDT entries, and I change offset (base address) of this GDT segment - must I refresh segment (or what this is called):
For example:
if i would unlimited the tss strucures count, I use one address for all tss'es - address 0x400000. Before I switch to the next task, scheduler map process tss to this address (in kernel's pgd and process's pgd)
*Sorry about language mistakes:)
