Lazy TSS's I/O bitmap update

Lazy TSS's I/O bitmap update patch is a software solution that has been designed for the i386 and x86-64 architecture. This innovative patch provides a unique approach to TSS's I/O bitmap copying by implementing lazy bitmap copy. This means that, unlike other solutions that copy the bitmap at every context switch, this patch sets the TSS's I/O bitmap offset to an invalid offset.

As a result, any attempt to access the bitmap from the CPU will trigger a GP fault. The bitmap is then lazily updated at this stage, thus avoiding bitmap copies in scenarios where the switched task does not perform any I/O operations. This approach has proven to be highly efficient and has been widely embraced by users across different computing environments.

Overall, Lazy TSS's I/O bitmap update patch offers a seamless experience and has become a go-to solution for anyone looking to optimize their computing performance. It is user-friendly and straightforward to implement, and its effectiveness has been validated by numerous positive reviews from satisfied users. Anyone looking for a way to optimize their computing can undoubtedly benefit from this patch.
