2019-03-18hw/char/parallel: Make it possible to compile also without CONFIG_PARALLELThomas Huth
For the downstream distribution of QEMU, we want to compile without CONFIG_PARALLEL. Commit 9157eee1b1c076ff3 already moved the function parallel_hds_isa_init() (which is still required for linking) into a file that is included anyway, but commit bb3d5ea858e7f888563a moved it to a separate file which is only compiled again if CONFIG_PARALLEL is set. To be able to link QEMU again without CONFIG_PARALLEL, the file should be considered for linking for all targets that have CONFIG_ISA_BUS. And while we're at it, add a proper comment in there with the rationale for the separate file.

2019-02-14hw/sparc64: Explicitly set default_display = "std"Thomas Huth
The sun4uv_init() function expects vga_interface_type to be either VGA_STD or VGA_NONE and sets up a stdvga device or no vga card accordingly. However, the code in vl.c prefers the Cirrus VGA card to stdvga if it is available and the user and the machine did not specify anything else. So far this has not been a problem, since the Cirrus VGA was not linked into the sparc64 target. But with the upcoming Kconfig build system, all theoretically possible PCI cards will be enabled by default, so the Cirrus VGA card might become available on the sparc64 target, too. vl.c then picks the wrong card, causing sun4uv_init() to abort. Thus let's make it explicit that we always want stdvga for sparc64 and so set default_display = "std" for these machines.

2019-02-05elf: Add optional function ptr to load_elf() to parse ELF notesLiam Merwick
This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

2018-07-02loader: Check access size when calling rom_ptr() to avoid crashesThomas Huth
The rom_ptr() function allows direct access to the ROM blobs that we load during startup. However, there are currently no checks for the size of the accesses, so it's currently possible to crash QEMU for example with: $ echo "Insane in the mainframe" > /tmp/test.txt $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -append xyz Segmentation fault (core dumped) $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -initrd /tmp/test.txt Segmentation fault (core dumped) $ echo -n HdrS > /tmp/hdr.txt $ sparc64-softmmu/qemu-system-sparc64 -kernel /tmp/hdr.txt -initrd /tmp/hdr.txt Segmentation fault (core dumped) We need a possibility to check the size of the ROM area that we want to access, thus let's add a size parameter to the rom_ptr() function to avoid these problems.

This inbuilt device contains a single 4-byte register, of which bit 24 is used to power down the machine on a real Ultra 5. The power device exists at offset 0x724000 on a real machine, but due to the current configuration of the BARs in QEMU it must be located lower in PCI IO space.

It is effectively a file rename from apb.c to sabre.c along with touching up a few constants to remove the remaining references to APB. Note that as part of the rename process the configuration variable CONFIG_PCI_APB is changed to CONFIG_PCI_SABRE.

This is in preparation to split the IOMMU device out of the APB. As part of this commit we also enforce separation of the IOMMU and APB devices by using a QOM object link to pass the IOMMU reference and accessing the IOMMU registers via a separate memory region mapped into the APB config space rather than directly.

2018-01-09ebus: wire up OBIO interrupts to APB pbm via qdev GPIOsMark Cave-Ayland
This enables us to remove the static array mapping in the ISA IRQ handler (and the embedded reference to the APB device) by formalising the interrupt wiring via the qdev GPIO API. For more clarity we replace the APB OBIO interrupt numbers with constants designating the interrupt source, and rename isa_irq_handler() to ebus_isa_irq_handler().

By making the special_base and mem_base values qdev properties, we can move the remaining parts of pci_apb_init() into the pbm init() and realize() functions. This finally allows us to instantiate the APB directly using standard qdev create/init functions in sun4u.c.
