From: Helge Deller <del...@gmx.de> There were some regressions introduced with Qemu v8.2 on the hppa/hppa64 target, e.g.:
- 32-bit HP-UX crashes on B160L (32-bit) machine - NetBSD boot failure due to power button in page zero - NetBSD FPU detection failure - OpenBSD 7.4 boot failure This small patch series fixes those known regressions and additionally: - allows usage of the max. 3840MB of memory (instead of 3GB), - adds support for the qemu --nodefaults option (to debug other devices) I tried to keep the patches small to make backporting easier. This patch set will not fix those known (non-regression) bugs: - HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine - Linux kernel will still fail to boot on C3700 as long as kernel modules are used. The whole series can be pulled from the "hppa-fixes-8.2" branch from: https://github.com/hdeller/qemu-hppa.git hppa-fixes-8.2 Changes v1->v2: - fix OpenBSD boot with SeaBIOS v15 instead of v14 - commit message enhancements suggested by BALATON Zoltan - use uint64_t for ram_max in patch #1 Helge Deller (9): hw/hppa/machine: Allow up to 3840 MB total memory hw/hppa/machine: Disable default devices with --nodefaults option hw/pci-host/astro: Add missing astro & elroy registers for NetBSD target/hppa: Fix PDC address translation on PA2.0 with PSW.W=0 target/hppa: Strip upper 32-bits of IOR on error in probe target/hppa: Strip upper 32-bits of IOR on unaligned access error hw/hppa: Move software power button address back into PDC target/hppa: Avoid accessing %gr0 when raising exception target/hppa: Update SeaBIOS-hppa to version 15 hw/hppa/machine.c | 33 ++++++++++++++++++++------------- hw/pci-host/astro.c | 26 +++++++++++++++++++++++--- pc-bios/hppa-firmware.img | Bin 681388 -> 163324 bytes roms/seabios-hppa | 2 +- target/hppa/cpu.c | 2 +- target/hppa/mem_helper.c | 4 ++-- target/hppa/op_helper.c | 2 +- 7 files changed, 48 insertions(+), 21 deletions(-) -- 2.43.0
