This patchset tries to address a discrepancy between the C3700 machine in QEMU/SeaBIOS and the documentation (chapter 5)
http://ftp.parisc-linux.org/docs/whitepapers/PA-8700wp.pdf where 40 bits of physical address space are used in SeaBIOS compared to the 44 bits specified in the documentation. A PA-8600 CPU with 40 bits of physical address space is added along with a C3600 machine using it by default. AFAICT there are no major differences from QEMUs side between the PA-8600 and 8700 aside from the physical address space size. The PA-8700 machine can then be moved to using 44 bits. To account for the discrepancy with SeaBIOS, the functional tests now run a C3700 but with a PA-8600 CPU. CPU model definitions now inherit from a TYPE_HPPA_CPU base class and use a HPPACPUDef struct to provide model specifics, similar to the SPARC and RISCV targets. This hopefully makes it easier to add other models, such as the 8800/8900. Based on: [PATCH v6 0/8] single-binary: Drop TARGET_PHYS_ADDR_SPACE_BITS ([email protected]) Signed-off-by: Anton Johansson <[email protected]> --- Changes in v3: - Fixed spelling in commit message/comment - Rebased - Dropped if statement in hppa_cpu_class_base_init() (patch "hppa: Introduce HPPACPUDef"). Not needed as it will simply be set to NULL for the abstract base class anyway. - Link to v2: https://lore.kernel.org/qemu-devel/[email protected] Changes in v2: - Missed a reference to the old "hppa" CPU model, updated to "pa-7300lc". - Link to v1: https://lore.kernel.org/qemu-devel/[email protected] --- Anton Johansson (4): hppa: Prepare for additional CPU models hppa: Introduce HPPACPUDef hppa: Get physical address space bits from HPPACPUDef hppa: Add C3600 machine with PA-8600 CPU target/hppa/cpu-qom.h | 8 ++++- target/hppa/cpu.h | 35 +++++++++++++++---- hw/hppa/machine.c | 64 +++++++++++++++++++++++++++-------- hw/pci-host/astro.c | 2 +- linux-user/hppa/elfload.c | 2 +- target/hppa/cpu.c | 50 ++++++++++++++++++++------- target/hppa/mem_helper.c | 40 +++++++--------------- tests/qtest/machine-none-test.c | 2 +- tests/functional/hppa/test_seabios.py | 3 ++ 9 files changed, 141 insertions(+), 65 deletions(-)
