1 TODO (know issues in CPU model):
2 -------------------------------
4 [!] The following 3DNow! instructions still not implemented:
24 [!] CPUID does not report 3DNow! instruction set
26 [!] Some of APIC functionality still not implemented, for example
28 - Globally disabled APIC
29 - NMI, SMI, INIT signals, LVT pins handling
30 - Filter interrupts according processor priority (PPR)
32 [!] REP NOP is PAUSE (on P4/XEON)
34 When running in SMP mode, this means that we are in a spin loop.
35 This processor should yield to the other one, as we are anyhow waiting
36 for a lock, and any other processor is responsible for this.
38 [!] Canonical fault in 64-bit mode not handled correctly in many many cases,
39 the exception is just missed.
41 [!] 32-bit linear address wrap when executing in legacy mode might be
42 not implemented correctly for system memory accesses (like descriptor
45 [!] AMD and Intel x86_64 implementations are different.
46 Currently Bochs emulation is according to AMD version.
47 Do we need to support both ?
49 [!] More flexible CPUID - vendor and etc
51 [!] SSE4A, SSE5A, VMX, SMX, SVM, AVX
