2025-02-04hw/pci-host/astro: Add LMMIO range supportHelge Deller1-0/+52
Each Astro on 64-bit machines supports up to four LMMIO regions. Those regions are used by graphic cards and other PCI devices which need to map huge memory areas. The LMMIO regions are configured and set up by SeaBIOS-hppa and then used as-is by the operating systems (Linux, HP-UX). With this addition it's now possible to add other PCI graphic cards on the command line, e.g. with "-device ati-vga". Signed-off-by: Helge Deller <deller@gmx.de>

2024-02-11hw/pci-host/astro: Implement Hard Fail and Soft Fail modeHelge Deller1-6/+15
The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode. Hard fail means the system bus will send an HPMC (=crash) to the processor, soft fail means the system bus will ignore timeouts of MMIO-reads or MMIO-writes and return -1ULL. The HF mode is controlled by a bit in the status register and is usually programmed by the OS. Return the corresponing values based on the current value of that bit.

https://github.com/hdeller/qemu-hppa into staging target/hppa qemu v8.2 regression fixes 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 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) 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. Changes v2->v3: - Added comment about Figures H-10 and H-11 in the parisc2.0 spec in patch which calculate PDC address translation if PSW.W=0 - Introduce and use hppa_set_ior_and_isr() - Use drive_get_max_bus(IF_SCSI), nd_table[] and serial_hd() to check if default devices should be created - Added Tested-by and Reviewed-by tags 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 # -----BEGIN PGP SIGNATURE----- # # iHUEABYKAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCZaImPQAKCRD3ErUQojoP # X2C5AP9fbIkCni45JU6KC6OmFsCbAReRQCPwLO+MzR8/us2ywgD+PsGxSBk8ASxM # nqtv3J9JC3i+XSnbtwLV+qChnO+IXwc= # =FAMY # -----END PGP SIGNATURE----- # gpg: Signature made Sat 13 Jan 2024 05:57:17 GMT # 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-fixes-8.2-pull-request' of https://github.com/hdeller/qemu-hppa: target/hppa: Update SeaBIOS-hppa to version 15 target/hppa: Fix IOR and ISR on error in probe target/hppa: Fix IOR and ISR on unaligned access trap target/hppa: Export function hppa_set_ior_and_isr() target/hppa: Avoid accessing %gr0 when raising exception hw/hppa: Move software power button address back into PDC target/hppa: Fix PDC address translation on PA2.0 with PSW.W=0 hw/pci-host/astro: Add missing astro & elroy registers for NetBSD hw/hppa/machine: Disable default devices with --nodefaults option hw/hppa/machine: Allow up to 3840 MB total memory Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2023-11-03hw/pci: modify pci_setup_iommu() to set PCIIOMMUOpsYi Liu1-1/+5
This patch modifies pci_setup_iommu() to set PCIIOMMUOps instead of setting PCIIOMMUFunc. PCIIOMMUFunc is used to get an address space for a PCI device in vendor specific way. The PCIIOMMUOps still offers this functionality. But using PCIIOMMUOps leaves space to add more iommu related vendor specific operations.
