From: Helge Deller <[email protected]> This patch series adds a new emulation for a HP PA-RISC 715/64 model, as it's descrived here: https://www.openpa.net/systems/hp-9000_715.html.
That machine has no PCI bus and instead uses a "LASI" chip which has built-in NCR710 SCSI and i82596 network chips. Compared to the other already emulated machines B160L and C3700, this machine should be able to support older operating systems like HP-UX 9 as well. The QEMU project participated in the Google Summer of Code 2025 program by "Implementing LASI Network Card and NCR 710 SCSI Controller Device Models", and Soumyajyotii Ssarkar stepped up to develop those drivers. This patch series includes the code for the NCR710 SCSI controller, the network code will follow in later patch series. Please review those patches. Helge & Soumyajyotii Helge Deller (7): target/hppa: Update SeaBIOS-hppa to version 19 hw/hppa: Fix firmware end address for LASI chip hw/hppa: Fix interrupt of LASI parallel port hw/hppa: Add the NCR 710 SCSI driver to hppa machines hw/hppa: PCI devices depend on availability of PCI bus hw/hppa: Require SeaBIOS version 19 for 715 machine hw/hppa: Add 715 machine type including NCR710 SCSI Soumyajyotii Ssarkar (3): ncr710: Add driver for the NCR 53c710 SCSI chip lasi: Forward LASI SCSI ports to NCR 53c710 driver hw/scsi: Add config option for new ncr710 driver hw/hppa/Kconfig | 1 + hw/hppa/hppa_hardware.h | 3 +- hw/hppa/machine.c | 110 +- hw/misc/lasi.c | 6 +- hw/scsi/Kconfig | 5 + hw/scsi/lasi_ncr710.c | 303 +++++ hw/scsi/lasi_ncr710.h | 53 + hw/scsi/meson.build | 1 + hw/scsi/ncr53c710.c | 2477 +++++++++++++++++++++++++++++++++++ hw/scsi/ncr53c710.h | 270 ++++ hw/scsi/trace-events | 33 + include/hw/misc/lasi.h | 2 + pc-bios/hppa-firmware.img | Bin 167644 -> 630056 bytes pc-bios/hppa-firmware64.img | Bin 206104 -> 699872 bytes roms/seabios-hppa | 2 +- 15 files changed, 3256 insertions(+), 10 deletions(-) create mode 100644 hw/scsi/lasi_ncr710.c create mode 100644 hw/scsi/lasi_ncr710.h create mode 100644 hw/scsi/ncr53c710.c create mode 100644 hw/scsi/ncr53c710.h -- 2.51.0
