| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'config' field in the VirtIOSerial structure keeps a copy of the virtio console's config space as visible to the guest, that is to say, in guest endianness. This is fiddly to maintain, because on some targets, such as powerpc, the "guest endianness" can change when a new guest OS boots. In fact, there's no need to maintain such a guest view of config space - instead we can reconstruct it from host-format data when it is accessed with get_config.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of places in the virtio_serial driver retrieve the number of ports from vser->config.max_nr_ports, which is guest-endian. But for internal users, we already have a host-endian copy of the number of ports in vser->serial.max_virtserial_ports. Using that instead of the config field removes the need for easy-to-forget byteswapping. In particular this fixes a bug on incoming migration, where we don't adjust the endianness vser->config correctly, because it hasn't yet been loaded from the migration stream when virtio_serial_load_device() is called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OSes typically write 0xdd/0xdf to turn the A20 line off and on. This has bits 2-3-6-7 on, so that the output port subsection is migrated. Change the reset value and migration default to include those four bits, thus avoiding that the subsection is migrated. This strictly speaking changes guest ABI, but the long time during which we have not migrated the value means that the guests really do not care much; so the change is for all machine types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the THR interrupt is disabled, there is no need to migrate thr_ipending because LSR.THRE will be sampled again when the interrupt is enabled. (This is the behavior that is not documented in the datasheet, but relied on by Windows!) Note that in this case IIR will never be 0x2 so, if thr_ipending were to be one, QEMU would produce the subsection.

Until now the logic was: create the usb controller if: - the usb option was supplied in cli and value is true or - the usb option was absent and both set_defaults and the machine condition were true. Modified the logic to: Create the usb controller if: - the machine condition is true and defaults are enabled or - the usb option is supplied and true. The main for this is to simplify the usb_enabled method.

When this field is set, it means that the portion of guest DRAM that the VCPU normally starts to execute, or the pflash chip that the VCPU normally starts to execute, has been populated by board-specific code with full-fledged guest firmware code, before the board calls arm_load_kernel(). Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board code has set up the global firmware config instance, for arm_load_kernel() to find with fw_cfg_find(). Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been possible to specify independently on the command line. The following cases should be considered: nr -bios -pflash -kernel description unit#0 -- ------- ------- ------- ------------------------------------------- 1 present present absent Board code rejects this case, -bios and present present present -pflash unit#0 are exclusive. Left intact by this patch. 2 absent absent present Traditional kernel loading, with qemu's minimal board firmware. Left intact by this patch. 3 absent present absent Preexistent case for booting guest firmware present absent absent loaded with -bios or -pflash. Left intact by this patch. 4 absent absent absent Preexistent case for not loading any firmware or kernel up-front. Left intact by this patch. 5 present absent present New case introduced by this patch: kernel absent present present image is passed to externally loaded firmware in unmodified form, using fw_cfg. An easy way to see that this patch doesn't interfere with existing cases is to realize that "info->firmware_loaded" is constant zero at this point. Which makes the "outer" condition unchanged, and the "inner" condition (with the fw_cfg-related code) dead.

Because MMIO access is slow on ARM KVM, we enable the guest, with fw_cfg_init_mem_wide(), to transfer up to 8 bytes with a single access. This has been measured to speed up transfers up to 7.5-fold, relative to single byte data access, on both ARM KVM and x86_64 TCG. The MMIO register block of fw_cfg is advertized in the device tree. As base address we pick 0x09020000, which conforms to the comment preceding "a15memmap": it falls in the miscellaneous device I/O range 128MB..256MB, and it is aligned at 64KB. The DTB properties follow the documentation in the Linux source file "Documentation/devicetree/bindings/arm/fw-cfg.txt". fw_cfg automatically exports a number of files to the guest; for example, "bootorder" (see fw_cfg_machine_reset()).

The behavior of the (big endian) multi-byte data reads is best shown with a qtest session. Here, we are reading the first six bytes of the UUID $ arm-softmmu/qemu-system-arm -M virt -machine accel=qtest \ -qtest stdio -uuid 4600cb32-38ec-4b2f-8acb-81c6ea54f2d8 >>> writew 0x9020008 0x0200 <<< OK >>> readl 0x9020000 <<< OK 0x000000004600cb32 Remember this is big endian. On big endian machines, it is stored directly as 0x46 0x00 0xcb 0x32. On a little endian machine, we have to first swap it, so that it becomes 0x32cb0046. When written to memory, it becomes 0x46 0x00 0xcb 0x32 again. Reading byte-by-byte works too, of course: >>> readb 0x9020000 <<< OK 0x0000000000000038 >>> readb 0x9020000 <<< OK 0x00000000000000ec Here only a single byte is read at a time, so they are read in order similar to the 1-byte data port that is already in PPC and SPARC machines.

| * | fw_cfg_mem: introduce the "data_width" propertyLaszlo Ersek2014-12-221-5/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "data_width" property is capable of changing the maximum valid access size to the MMIO data register, and resizes the memory region similarly, at device realization time. The default value of "data_memwidth" is set so that we don't yet diverge from "fw_cfg_data_mem_ops". Most of the fw_cfg_mem users will stick with the default, and for them we should continue using the statically allocated "fw_cfg_data_mem_ops". This is beneficial for debugging because gdb can resolve pointers referencing static objects to the names of those objects.

| * | fw_cfg: hard separation between the MMIO and I/O port mappingsLaszlo Ersek2014-12-223-55/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are going to introduce a wide data register for fw_cfg, but only for the MMIO mapped device. The wide data register will also require the tightening of endiannesses. However we don't want to touch the I/O port mapped fw_cfg device at all. Currently QEMU provides a single fw_cfg device type that can handle both I/O port and MMIO mapping. This flexibility is not actually exploited by any board in the tree, but it renders restricting the above changes to MMIO very hard. Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and TYPE_FW_CFG_MEM. TYPE_FW_CFG_IO incorporates the base I/O port and the related combined MemoryRegion. (NB: all boards in the tree that use the I/O port mapped flavor opt for the combined mapping; that is, when the data port overlays the high address byte of the selector port. Therefore we can drop the capability to map those I/O ports separately.) TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and data registers, and their respective MemoryRegions. The "realize" and "props" class members are specific to each new derived class, and become unused for the base class. The base class retains the "reset" member and the "vmsd" member, because the reset functionality and the set of migrated data are not specific to the mapping. The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the possible mappings in separation. For now fw_cfg_init() is retained as a compatibility shim that enforces the above assumptions.
