qemu-e2k/target/ppc/STATUS
Thomas Huth fcf5ef2ab5 Move target-* CPU file into a target/ folder 
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

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

PowerPC microcontrollers emulation status
Implemementation should be sufficient to boot Linux:
(there seem to be problems with uboot freezing at some point)
- PowerPC 405CR
- PowerPC 405EP
TODO:
- PowerPC 401 microcontrollers emulation
- PowerPC 403 microcontrollers emulation
- more PowerPC 405 microcontrollers emulation
- Fixes / more features for implemented PowerPC 405 microcontrollers emulation
- PowerPC 440 microcontrollers emulation
- e200 microcontrollers emulation
- e300 microcontrollers emulation
- e500 microcontrollers emulation
- e600 microcontrollers emulation
===============================================================================
PowerPC based platforms emulation status
* PREP platform (RS/6000 7043...) - TO BE CHECKED (broken)
- Gentoo Linux live CDROM 1.4
- Debian Linux 3.0
- Mandrake Linux 9
* heathrow PowerMac platform (beige PowerMac) - TO BE CHECKED (broken)
- 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
- ePPAR emulation
- misc PowerPC reference boards emulation
