  "message": "hw/i386: Assume fw_cfg DMA is always enabled\n\nNow all calls of x86 machines to fw_cfg_init_io_dma() pass DMA\narguments, so the FWCfgState (FWCfgIoState) created by x86 machines\nenables DMA by default.\n\nAlthough other callers of fw_cfg_init_io_dma() besides x86 also pass\nDMA arguments to create DMA-enabled FwCfgIoState, the \"dma_enabled\"\nproperty of FwCfgIoState cannot yet be removed, because Sun4u and Sun4v\nstill create DMA-disabled FwCfgIoState (bypass fw_cfg_init_io_dma()) in\nsun4uv_init() (hw/sparc64/sun4u.c).\n\nMaybe reusing fw_cfg_init_io_dma() for them would be a better choice, or\nadding fw_cfg_init_io_nodma(). However, before that, first simplify the\nhandling of FwCfgState in x86.\n\nConsidering that FwCfgIoState in x86 enables DMA by default, remove the\nhandling for DMA-disabled cases and replace DMA checks with assertions\nto ensure that the default DMA-enabled setting is not broken.\n\nThen \u0027linuxboot.bin\u0027 isn\u0027t used anymore, and it will be removed in the\nnext commit.\n\nSigned-off-by: Philippe Mathieu-Daudé \u003cphilmd@linaro.org\u003e\nSigned-off-by: Zhao Liu \u003czhao1.liu@intel.com\u003e\nAcked-by: Igor Mammedov \u003cimammedo@redhat.com\u003e\nReviewed-by: Thomas Huth \u003cthuth@redhat.com\u003e\nLink: https://lore.kernel.org/r/20260108033051.777361-15-zhao1.liu@intel.com\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\n",
