2025-07-04monitor/hmp-cmds-target: add CPU_DUMP_VPU in hmp_info_registers()Daniel Henrique Barboza1-2/+2
Commit b84694defb added the CPU_DUMP_VPU to allow vector registers to be logged by log_cpu_exec() in TCG. This flag was then used in commit b227f6a8a7 to print RISC-V vector registers using this flag. Note that this change was done in riscv_cpu_dump_state(), the cpu_dump_state() callback for RISC-V, the same callback used in hmp_info_registers(). Back then we forgot to change hmp_info_registers(), and 'info registers' isn't showing RISC-V vector registers as a result. No other target is impacted since only RISC-V is using CPU_DUMP_VPU. There's no reason to not show VPU regs in info_registers(), so add CPU_DUMP_VPU to hmp_info_registers(). This will print vector registers for all RISC-V machines and, as said above, has no impact in other archs.

2025-07-02virtio-gpu: support context init multiple timelineYiwei Zhang1-0/+44
Venus and later native contexts have their own fence context along with multiple timelines within. Fences wtih VIRTIO_GPU_FLAG_INFO_RING_IDX in the flags must be dispatched to be created on the target context. Fence signaling also has to be handled on the specific timeline within that target context. Before this change, venus fencing is completely broken if the host driver doesn't support implicit fencing with external memory objects. Frames can go backwards along with random artifacts on screen if the host driver doesn't attach an implicit fence to the render target. The symptom could be hidden by certain guest wsi backend that waits on a venus native VkFence object for the actual payload with limited present modes or under special configs. e.g. x11 mailbox or xwayland. After this change, everything related to venus fencing starts making sense. Confirmed this via guest and host side perfetto tracing.

2025-07-02MAINTAINERS: add myself to virtio-gpu for Odd FixesAlex Bennée1-1/+2
Seeing as I've taken a few patches to here now I might as well put myself forward to maintain virtio-gpu. I've marked it as Odd Fixes as it is not my core focus. If someone with more GPU experience comes forward we can always update again.

2025-07-02plugins: Add patcher plugin and testRowan Hart6-2/+328
This patch adds a plugin that exercises the virtual and hardware memory read-write API functions added in a previous patch. The plugin takes a target and patch byte sequence, and will overwrite any instruction matching the target byte sequence with the patch.

2025-07-02plugins: Add memory hardware address read/write APIRowan Hart2-0/+190
This patch adds functions to the plugins API to allow plugins to read and write memory via hardware addresses. The functions use the current address space of the current CPU in order to avoid exposing address space information to users. A later patch may want to add a function to permit a specified address space, for example to facilitate architecture-specific plugins that want to operate on them, for example reading ARM secure memory.

2025-07-02plugins: Add memory virtual address write APIRowan Hart2-0/+39
This patch adds functions to the plugins API to allow reading and writing memory via virtual addresses. These functions only permit doing so on the current CPU, because there is no way to ensure consistency if plugins are allowed to read or write to other CPUs that aren't currently in the context of the plugin.

2025-07-02plugins: Add enforcement of QEMU_PLUGIN_CB flags in register R/W callbacksRowan Hart6-6/+96
This patch adds functionality to enforce the requested QEMU_PLUGIN_CB_ flags level passed when registering a callback function using the plugins API. Each time a callback is about to be invoked, a thread-local variable will be updated with the level that callback requested. Then, called API functions (in particular, the register read and write API) will call qemu_plugin_get_cb_flags() to check the level is at least the level they require.
