This patchset adds support for the IBM PPE42 processor, including a simple machine providing a platform for testing the PPE42 instructions.
The PPE42 processor is used as an embedded processor in the IBM Power9, Power10 and Power12 processors for various tasks. It is basically a stripped down version of the IBM PowerPC 405 processor, with some added instructions for handling 64-bit loads and stores and some 64-bit logical operations. For more information on the PPE 42 processor please visit: https://wiki.raptorcs.com/w/images/a/a3/PPE_42X_Core_Users_Manual.pdf A functional test is included. This test downloads a prebuilt test image from: https://github.com/milesg-github/ppe42-tests Building the image rquires a forked version of an old version of GCC, which can be found here: https://github.com/open-power/ppe42-gcc Thanks, Glenn Glenn Miles (4): target/ppc: Add IBM PPE42 family of processors target/ppc: Add IBM PPE42 special instructions hw/ppc: Add a test machine for the IBM PPE42 CPU tests/functional: Add test for IBM PPE42 instructions hw/ppc/Kconfig | 9 + hw/ppc/meson.build | 2 + hw/ppc/ppc_booke.c | 7 +- hw/ppc/ppe42_machine.c | 69 +++ include/hw/ppc/ppc.h | 1 + target/ppc/cpu-models.c | 7 + target/ppc/cpu-models.h | 4 + target/ppc/cpu.h | 66 ++- target/ppc/cpu_init.c | 286 ++++++++-- target/ppc/excp_helper.c | 171 ++++++ target/ppc/helper_regs.c | 28 +- target/ppc/insn32.decode | 66 ++- target/ppc/tcg-excp_helper.c | 12 + target/ppc/translate.c | 35 +- target/ppc/translate/ppe-impl.c.inc | 805 ++++++++++++++++++++++++++++ tests/functional/meson.build | 1 + tests/functional/test_ppc_ppe42.py | 79 +++ 17 files changed, 1592 insertions(+), 56 deletions(-) create mode 100644 hw/ppc/ppe42_machine.c create mode 100644 target/ppc/translate/ppe-impl.c.inc create mode 100644 tests/functional/test_ppc_ppe42.py -- 2.43.0
