Subject: [Qemu-devel] Wrong Exception - should have GPF instead of PF for NULL selector
Date: Sat, 12 Jun 2004 15:34:43 +0100 [thread overview]
Message-ID: <1087050882.597.6.camel@pcgem.rdg.cyberkinetica.com> (raw)
I have been looking at why OS/2 Warp Connect fails to start Presentation
Manager under QEMU and I have found the following...
We get a Page Fault when QEMU encounters the following instruction
0xfe0a9971: mov %es:(%si),%ebx
Where ES=0x0000 and ESI=0xabde0000
This should generate a General Protection exception as we are accessing
memory using a NULL selector
I don't know if it would fix OS/2 but it is definitely behaviour which
is 'not correct'.
