| PowerPC emulation status. |
| The goal of this file is to provide a reference status to avoid regressions. |
| |
| =============================================================================== |
| PowerPC core emulation status |
| |
| INSN: instruction set. |
| OK => all instructions are emulated |
| KO => some insns are missing or some should be removed |
| ? => unchecked |
| SPR: special purpose registers set |
| OK => all SPR registered (but some may be fake) |
| KO => some SPR are missing or should be removed |
| ? => unchecked |
| MSR: MSR bits definitions |
| OK => all MSR bits properly defined |
| KO => MSR definition is incorrect |
| ? => unchecked |
| IRQ: input signals definitions (mostly interrupts) |
| OK => input signals are properly defined |
| KO => input signals are not implemented (system emulation does not work) |
| ? => input signals definitions may be incorrect |
| MMU: MMU model implementation |
| OK => MMU model is implemented and Linux is able to boot |
| KO => MMU model not implemented or bugged |
| ? => MMU model not tested |
| EXCP: exceptions model implementation |
| OK => exception model is implemented and Linux is able to boot |
| KO => exception model not implemented or known to be buggy |
| ? => exception model may be incorrect or is untested |

| * PREP platform (RS/6000 7043...) - TO BE CHECKED (broken) |
| - Gentoo Linux live CDROM 1.4 |
| - Debian Linux 3.0 |
| - Mandrake Linux 9 |

| - Gentoo Linux live CDROM 1.4 |
| - Debian Linux 3.0 |
| - Mandrake Linux 9 |
| |
| * mac99 platform (white and blue PowerMac, ...) |
| - Gentoo Linux live CDROM 1.4 - boots, compiles linux kernel |
| - Debian Linux woody - boots from CDROM and HDD |
| - Mandrake Linux 9 - boots from CDROM, freezes during install |
| - Knoppix 2003-07-13_4 boots from CDROM, pb with X configuration |
| distribution bug: X runs with a properly hand-coded configuration. |
| - rock Linux 2.0 runs from CDROM |
| |
| * Linux 2.6 support seems deadly broken (used to boot...). |
| |
| * PowerPC 405EP reference boards: |
| - can boot Linux 2.4 & 2.6. |
| Need to provide a flash image ready to boot for reproductible tests. |
| |
| TODO: |
| - URGENT: fix PreP and heathrow platforms |
| - PowerPC 64 reference platform |
| - MCA based RS/6000 emulation |
| - CHRP emulation (not PowerMac) |
| - PPAR emulation |
