* hw/nvram/aspeed_otp: Add OTP programming semantics and tracingKane-Chen-AS2025-09-292-1/+84
| | | | | | | | | | | | | | | | | | | | | Implement correct OTP programming behavior for Aspeed OTP: - Support read-modify-write flow with one-way bit programming: * prog_bit uses 0s as the "to-be-programmed" mask. * Even-indexed words: 0->1, odd-indexed words: 1->0. * Reject non-programmable requests and log conflicts. - Enable unaligned accesses in MemoryRegionOps. Since each OTP address maps to a 1DW (4B) or 2DW (8B) block in the backing store, upper-layer accesses may be unaligned to block boundaries. This matches the irreversible, word-parity-dependent programming rules of Aspeed SoCs and exposes changes via QEMU trace events.

* hw/nvram/aspeed_otp: Add 'drive' property to support block backendKane-Chen-AS2025-09-291-1/+14
| | | | | | | | | | | | | | | | | | | | This patch introduces a 'drive' property to the Aspeed OTP device, allowing it to be backed by a block device. Users can now preload OTP data via QEMU CLI using a block backend. Example usage: ./qemu-system-arm \ -blockdev driver=file,filename=otpmem.img,node-name=otp \ -global aspeed-otp.drive=otp \ ... If the drive is provided, its content will be loaded as the initial OTP state. Otherwise, an internal memory buffer will be used.

* hw/nvram/aspeed_otp: Add ASPEED OTP memory device modelKane-Chen-AS2025-09-292-0/+103
| | | | | | | | | | | | | | | | | | Introduce a QEMU device model for ASPEED's One-Time Programmable (OTP) memory. This model simulates a word-addressable OTP region used for secure fuse storage. The OTP memory can operate with an internal memory buffer. The OTP model provides a memory-like interface through a dedicated AddressSpace, allowing other device models (e.g., SBC) to issue transactions as if accessing a memory-mapped region.

* fw_cfg: Don't set callback_opaque NULL in fw_cfg_modify_bytes_read()Shameer Kolothum2024-12-311-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On arm/virt platform, Chen Xiang reported a Guest crash while attempting the below steps, 1. Launch the Guest with nvdimm=on 2. Hot-add a NVDIMM dev 3. Reboot 4. Guest boots fine. 5. Reboot again. 6. Guest boot fails. QEMU_EFI reports the below error: ProcessCmdAddPointer: invalid pointer value in "etc/acpi/tables" OnRootBridgesConnected: InstallAcpiTables: Protocol Error Debugging shows that on first reboot(after hot adding NVDIMM), Qemu updates the etc/table-loader len, qemu_ram_resize()   fw_cfg_modify_file()      fw_cfg_modify_bytes_read() And in fw_cfg_modify_bytes_read() we set the "callback_opaque" for the key entry to NULL. Because of this, on the second reboot, virt_acpi_build_update() is called with a NULL "build_state" and returns without updating the ACPI tables. This seems to be upsetting the firmware. To fix this, don't change the callback_opaque in fw_cfg_modify_bytes_read().

This means that if a device cared about the ResetType it would need to record it in the enter phase method to use later on. Pass the type to all three of the phase methods to avoid having to do that.
