[Qemu-devel] QEMU regression problems

[Gerhard Wiesinger]

Hello,

Checkit reports some problems under DOS:
1.) NPU functions are not correct: NPU Trigonometric Functions: FAILED. 
Seems to be a problem of the instruction set.
2.) Real-Time Clock Alarm: FAILED (This might be also the reason for the
KVM problem, see my previous post). Seems to be that real-time clock is 
not working correct.
3.) There is also a problem with the reported base memory under QEMM386
(HIMEM.SYS and EMM386.EXE is correct here). It is 646kB instead of 640kB.
Therefore base memory test fails. I guess that reporting memory CMOS 
tables/interrupt functions are not implemented correctly.

Details are listed below.

All issues are NOT present under VMWare Server 2.0 and with real hardware.

QEMU: 0.12.3 under Fedora 11, 2.6.30.10-105.2.23.fc11.x86 on AMD Phenom II 
Quad Core, x86_64-softmmu.

Any comments?

Thnx.

Ciao,
Gerhard
