AFAICT there are no major\ndifferences from QEMUs side between the PA-8600 and 8700 aside from the\nphysical address space size. The PA-8700 machine can then be\nmoved to using 44 bits. To account for the discrepancy with SeaBIOS, the\nfunctional tests now run a C3700 but with a PA-8600 CPU.\n\nCPU model definitions now inherit from a TYPE_HPPA_CPU base class and\nuse a HPPACPUDef struct to provide model specifics, similar to the SPARC\nand RISCV targets. This hopefully makes it easier to add other models,\nsuch as the 8800/8900.\n\nBased on:\n [PATCH v6 0/8] single-binary: Drop TARGET_PHYS_ADDR_SPACE_BITS\n (20260218-phys_addr-v6-0-a603bf363218@rev.ng)\n\nSigned-off-by: Anton Johansson \n---\nChanges in v3:\n- Fixed spelling in commit message/comment\n- Rebased\n- Dropped if statement in hppa_cpu_class_base_init() (patch\n \"hppa: Introduce HPPACPUDef\"). Not needed as it will simply\n be set to NULL for the abstract base class anyway.\n- Link to v2: https://lore.kernel.org/qemu-devel/20260210-hppa-c3600-v2-0-9ca09c677012@rev.ng\n\nChanges in v2:\n- Missed a reference to the old \"hppa\" CPU model, updated to\n \"pa-7300lc\".\n- Link to v1: https://lore.kernel.org/qemu-devel/20260210-hppa-c3600-v1-0-a17ec58f053f@rev.ng\n\n---\nAnton Johansson (4):\n hppa: Prepare for additional CPU models\n hppa: Introduce HPPACPUDef\n hppa: Get physical address space bits from HPPACPUDef\n hppa: Add C3600 machine with PA-8600 CPU\n\n target/hppa/cpu-qom.h | 8 ++++-\n target/hppa/cpu.h | 35 +++++++++++++++----\n hw/hppa/machine.c | 64 +++++++++++++++++++++++++++--------\n hw/pci-host/astro.c | 2 +-\n linux-user/hppa/elfload.c | 2 +-\n target/hppa/cpu.c | 50 ++++++++++++++++++++-------\n target/hppa/mem_helper.c | 40 +++++++---------------\n tests/qtest/machine-none-test.c | 2 +-\n tests/functional/hppa/test_seabios.py | 3 ++\n 9 files changed, 141 insertions(+), 65 deletions(-)"}
