Implemementation should be sufficient to boot Linux:

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:
- MCA based RS/6000 emulation
- CHRP emulation (not PowerMac)

Great PowerPC emulation code resynchronisation and improvments: - Add status file to make regression tracking easier - Move all micro-operations helpers definitions into a separate header: should never be seen outside of op.c - Update copyrights - Add new / missing PowerPC CPU definitions - Add definitions for PowerPC BookE - Add support for PowerPC 6xx/7xx software driven TLBs Allow use of PowerPC 603 as an example - Add preliminary code for POWER, POWER2, PowerPC 403, 405, 440, 601, 602 and BookE support - Avoid compiling priviledged only resources support for user-mode emulation - Remove unused helpers / micro-ops / dead code - Add instructions usage statistics dump: useful to figure which instructions need strong optimizations. - Micro-operation fixes: * add missing RETURN in some micro-ops * fix prototypes * use softfloat routines for all floating-point operations * fix tlbie instruction * move some huge micro-operations into helpers - emulation fixes: * fix inverted opcodes for fcmpo / fcmpu * condition register update is always to be done after the whole instruction has completed * add missing NIP updates when calling helpers that may generate an exception - optimizations and improvments: * optimize very often used instructions (li, mr, rlwixx...) * remove specific micro-ops for rarely used instructions * add routines for addresses computations to avoid bugs due to multiple different implementations * fix TB linking: do not reset T0 at the end of every TB. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2473 c046a42c-6fe2-441c-8c8c-71466251a162 2007-03-07 09:32:30 +01:00			`PowerPC emulation status.`

More PowerPC definitions, from POWER 2.04 specifications and misc sources. Check that at least instructions set and SPRs are correct for PowerPC 401, 403, 405 and 440 cores. Implement PowerPC 401 MMU model (real-mode only). Improve INSNs and SPRs dump to ease parse with standard shell tools. Add more precise status for most PowerPC cores families. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3201 c046a42c-6fe2-441c-8c8c-71466251a162 2007-09-21 07:50:37 +02:00			`32 bits PowerPC`

			`- PPAR emulation`
Update PowerPC target status. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2724 c046a42c-6fe2-441c-8c8c-71466251a162 2007-04-24 09:51:56 +02:00			`- ePPAR emulation`
Great PowerPC emulation code resynchronisation and improvments: - Add status file to make regression tracking easier - Move all micro-operations helpers definitions into a separate header: should never be seen outside of op.c - Update copyrights - Add new / missing PowerPC CPU definitions - Add definitions for PowerPC BookE - Add support for PowerPC 6xx/7xx software driven TLBs Allow use of PowerPC 603 as an example - Add preliminary code for POWER, POWER2, PowerPC 403, 405, 440, 601, 602 and BookE support - Avoid compiling priviledged only resources support for user-mode emulation - Remove unused helpers / micro-ops / dead code - Add instructions usage statistics dump: useful to figure which instructions need strong optimizations. - Micro-operation fixes: * add missing RETURN in some micro-ops * fix prototypes * use softfloat routines for all floating-point operations * fix tlbie instruction * move some huge micro-operations into helpers - emulation fixes: * fix inverted opcodes for fcmpo / fcmpu * condition register update is always to be done after the whole instruction has completed * add missing NIP updates when calling helpers that may generate an exception - optimizations and improvments: * optimize very often used instructions (li, mr, rlwixx...) * remove specific micro-ops for rarely used instructions * add routines for addresses computations to avoid bugs due to multiple different implementations * fix TB linking: do not reset T0 at the end of every TB. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2473 c046a42c-6fe2-441c-8c8c-71466251a162 2007-03-07 09:32:30 +01:00			`- misc PowerPC reference boards emulation`
