Merge tag 'hppa-boot-reboot-fixes-pull-request' of https://github.com/hdeller/qemu-hppa into staging
target/hppa: Fix boot and reboot for SMP machines Fix some SMP-related boot and reboot issues with HP-UX and Linux by correctly initializing the CPU PSW bits, disabling data and instruction translations and unhalting the CPU in the qemu hppa_machine_reset() function. To work correctly some fixes are needed in the SeaBIOS-hppa firmware too, which is why this series updates it to version 8 which includes those fixes and enhancements: Fixes - boot of HP-UX with SMP, and - reboot of Linux and HP-UX with SMP Enhancements: - show qemu version in boot menu - adds exit menu entry in boot menu to quit emulation - allow to trace PCD_CHASSIS codes more specifically Signed-off-by: Helge Deller <deller@gmx.de> # -----BEGIN PGP SIGNATURE----- # # iHUEABYKAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCZJbYWAAKCRD3ErUQojoP # X6ExAQCmOXqwJw3SjSE/+hvphJ2mMTJe3i6dU3AWOGlACxxVzAEA7dKSU4d8EtRj # NZpGKB9NE9eWwQFGJVbVgFeikap44gs= # =8zCK # -----END PGP SIGNATURE----- # gpg: Signature made Sat 24 Jun 2023 01:49:44 PM CEST # gpg: using EDDSA key BCE9123E1AD29F07C049BBDEF712B510A23A0F5F # gpg: Good signature from "Helge Deller <deller@gmx.de>" [unknown] # gpg: aka "Helge Deller <deller@kernel.org>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 4544 8228 2CD9 10DB EF3D 25F8 3E5F 3D04 A7A2 4603 # Subkey fingerprint: BCE9 123E 1AD2 9F07 C049 BBDE F712 B510 A23A 0F5F * tag 'hppa-boot-reboot-fixes-pull-request' of https://github.com/hdeller/qemu-hppa: target/hppa: Update to SeaBIOS-hppa version 8 target/hppa: Provide qemu version via fw_cfg to firmware target/hppa: Fix OS reboot issues Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
