The vring.c code currently assumes that guest and host endianness match, which is not true for a number of cases: - emulating targets with a different endianness than the host - bi-endian targets, where the correct endianness depends on the virtio device - upcoming support for the virtio-1 standard mandates little-endian accesses even for big-endian targets and hosts Make sure to use accessors that depend on the virtio device. Note that dataplane now needs to be built per-target.

With simple exposure of MMFG, ioport window, mmio window and an IRQ line we can successfully create a workable PCIe host bridge that can be mapped anywhere and only needs to get described to the OS using whatever means it likes. This patch implements such a "generic" host bridge. It handles 4 legacy IRQ lines. MSIs need to be handled external to the host bridge. This device is particularly useful for the "pci-host-ecam-generic" driver in Linux.

this patch finally introduces multiread support to virtio-blk. While multiwrite support was there for a long time, read support was missing. The complete merge logic is moved into virtio-blk.c which has been the only user of request merging ever since. This is required to be able to merge chunks of requests and immediately invoke callbacks for those requests. Secondly, this is required to switch to direct invocation of coroutines which is planned at a later stage. The following benchmarks show the performance of running fio with 4 worker threads on a local ram disk. The numbers show the average of 10 test runs after 1 run as warmup phase. | 4k | 64k | 4k MB/s | rd seq | rd rand | rd seq | rd rand | wr seq | wr rand --------------+--------+---------+--------+---------+--------+-------- master | 1221 | 1187 | 4178 | 4114 | 1745 | 1213 multiread | 1829 | 1189 | 4639 | 4110 | 1894 | 1216 Signed-off-by: NPeter Lieven <pl@kamp.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM functions. Add such properties to the ICH9 chipset as well for the Q35 machine type. S3 / S4 are not guaranteed to always work (needs work in the guest as well as QEMU for things to work properly), and disabling advertising of these features ensures guests don't go into zombie state if something isn't working right. The defaults are kept the same as in PIIX4: both S3 and S4 are enabled by default. These can be disabled via the cmdline: ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1 Note: some guests can fake hibernation by writing a hibernate image and doing a shutdown instead of S4 if S4 isn't available; there's nothing we can do guests to stop doing this, and this patch can't affect that functionality.

The ioreq-server API added to Xen 4.5 offers better security than the existing Xen/QEMU interface because the shared pages that are used to pass emulation request/results back and forth are removed from the guest's memory space before any requests are serviced. This prevents the guest from mapping these pages (they are in a well known location) and attempting to attack QEMU by synthesizing its own request structures. Hence, this patch modifies configure to detect whether the API is available, and adds the necessary code to use the API if it is.

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.

Introduce the new boolean field "arm_boot_info.firmware_loaded". 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.

We rebase fw_cfg_init_mem() to the new function for compatibility with current callers. 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.

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.
