2013-10-11Mostly revert "qemu-help: Sort devices by logical functionality"Markus Armbruster
This reverts most of commit 3d1237fb2ab4edb926c717767bb5e31d6053a7c5. The commit claims to sort the output of "-device help" "by functionality rather than alphabetical". Issues: * The output was unsorted before, not alphabetically sorted. Misleading, but harmless enough. * The commit doesn't just sort the output of "-device help" as it claims, it adds categories to each line of "-device help", and it prints devices once per category. In particular, devices without a category aren't shown anymore. Maybe such devices should not exist, but they do. Regression. * Categories are also added to the output of "info qdm". Silent change, not nice. Output remains unsorted, unlike "-device help". I'm going to reimplement the feature we actually want, without the warts. Reverting the flawed commit first should make it easier to review. However, I can't revert it completely, since DeviceClass member categories has been put to use. So leave that part in.

2013-10-02target-i386: Set model=6 on qemu64 & qemu32 CPU modelsEduardo Habkost
There's no Intel CPU with family=6,model=2, and Linux and Windows guests disable SEP when seeing that combination due to Pentium Pro erratum #82. In addition to just having SEP ignored by guests, Skype (and maybe other applications) runs sysenter directly without passing through ntdll on Windows, and crashes because Windows ignored the SEP CPUID bit. So, having model > 2 is a better default on qemu64 and qemu32 for two reasons: making SEP really available for guests, and avoiding crashing applications that work on bare metal. model=3 would fix the problem, but it causes CPU enumeration problems for Windows guests[1]. So let's set model=6, that matches "Athlon (PM core)" on AMD and "P2 with on-die L2 cache" on Intel and it allows Windows to use all CPUs as well as fixing sysenter.

2013-09-28smbios: Make multiple -smbios type= accumulate sanelyMarkus Armbruster
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with value VAL to fw_cfg for each unique NAME. If NAME occurs multiple times, the last one's VAL is used (before the QemuOpts conversion, the first one was used). Multiple -smbios can add multiple fields with the same (T, NAME). SeaBIOS reads all of them from fw_cfg, but uses only the first field (T, NAME). The others are ignored. "First one wins, subsequent ones get ignored silently" isn't nice. We commonly let the last option win. Useful, because it lets you -readconfig first, then selectively override with command line options. Clean up -smbios to work the common way. Accumulate the settings, with later ones overwriting earlier ones. Put the result into fw_cfg (no more useless duplicates). Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by side effect.

2013-09-20virtio-blk: do not relay a previous driver's WCE configuration to the currentPaolo Bonzini
The following sequence happens: - the SeaBIOS virtio-blk driver does not support the WCE feature, which causes QEMU to disable writeback caching - the Linux virtio-blk driver resets the device, finds WCE is available but writeback caching is disabled; tells block layer to not send cache flush commands - the Linux virtio-blk driver sets the DRIVER_OK bit, which causes writeback caching to be re-enabled, but the Linux virtio-blk driver does not know of this side effect and cache flushes remain disabled The bug is at the third step. If the guest does know about CONFIG_WCE, QEMU should ignore the WCE feature's state. The guest will control the cache mode solely using configuration space. This change makes Linux do flushes correctly, but Linux will keep SeaBIOS's writethrough mode. Hence, whenever the guest is reset, the cache mode of the disk should be reset to whatever was specified in the "-drive" option. With this change, the Linux virtio-blk driver finds that writeback caching is enabled, and tells the block layer to send cache flush commands appropriately.

2013-09-06e1000: add interrupt mitigation supportVincenzo Maffione
This patch partially implements the e1000 interrupt mitigation mechanisms. Using a single QEMUTimer, it emulates the ITR register (which is the newer mitigation register, recommended by Intel) and approximately emulates RADV and TADV registers. TIDV and RDTR register functionalities are not emulated (RDTR is only used to validate RADV, according to the e1000 specs). RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation mechanism and would need a timer each to be completely emulated. However, a single timer has been used in order to reach a good compromise between emulation accuracy and simplicity/efficiency. The implemented mechanism can be enabled/disabled specifying the command line e1000-specific boolean parameter "mitigation", e.g. qemu-system-x86_64 -device e1000,mitigation=on,... ... For more information, see the Software developer's manual at http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf. Interrupt mitigation boosts performance when the guest suffers from an high interrupt rate (i.e. receiving short UDP packets at high packet rate).

2013-09-02spapr-pci: rework MSI/MSIXAlexey Kardashevskiy
On the sPAPR platform a guest allocates MSI/MSIX vectors via RTAS hypercalls which return global IRQ numbers to a guest so it only operates with those and never touches MSIMessage. Therefore MSIMessage handling is completely hidden in QEMU. Previously every sPAPR PCI host bridge implemented its own MSI window to catch msi_notify()/msix_notify() calls from QEMU devices (virtio-pci or vfio) and route them to the guest via qemu_pulse_irq(). MSIMessage used to be encoded as: .addr - address within the PHB MSI window; .data - the device index on PHB plus vector number. The MSI MR write function translated this MSIMessage to a global IRQ number and called qemu_pulse_irq(). However the total number of IRQs is not really big (at the moment it is 1024 IRQs starting from 4096) and even 16bit data field of MSIMessage seems to be enough to store an IRQ number there. This simplifies MSI handling in sPAPR PHB. Specifically, this does: 1. remove a MSI window from a PHB; 2. add a single memory region for all MSIs to sPAPREnvironment and spapr_pci_msi_init() to initialize it; 3. encode MSIMessage as: * .addr - a fixed address of SPAPR_PCI_MSI_WINDOW==0x40000000000ULL; * .data as an IRQ number. 4. change IRQ allocator to align first IRQ number in a block for MSI. MSI uses lower bits to specify the vector number so the first IRQ has to be aligned. MSIX does not need any special allocator though.

2013-09-01pc: reduce duplication, fix PIIX descriptionsMichael S. Tsirkin
We have a lot of code duplication between machine types, this increases with each new machine type and each new field. This has already introduced a minor bug: description for pc-1.3 says "Standard PC" while description for pc-1.4 is "Standard PC (i440FX + PIIX, 1996)" which makes you think 1.3 is somehow more standard, or newer, while in fact it's a revision of the same PC. This patch addresses this issue by using macros, along the lines used by PC_COMPAT_X_X - only for non-property options. The approach can extend to non-PC machine types.

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster
We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.

2013-08-27pc: fix regression for 64 bit PCI memoryMichael S. Tsirkin
commit 398489018183d613306ab022653552247d93919f pc: limit 64 bit hole to 2G by default introduced a way for management to control the window allocated to the 64 bit PCI hole. This is useful, but existing management tools do not know how to set this property. As a result, e.g. specifying a large ivshmem device with size > 4G is broken by default. For example this configuration no longer works: -device ivshmem,size=4294967296,chardev=cfoo -chardev socket,path=/tmp/sock,id=cfoo,server,nowait Fix this by detecting that hole size was not specified and defaulting to the backwards-compatible value of 1 << 62.

2013-08-27pci: Introduce helper to retrieve a PCI device's DMA address spaceAlexey Kardashevskiy
A PCI device's DMA address space (possibly an IOMMU) is returned by a method on the PCIBus. At the moment that only has one caller, so the method is simply open coded. We'll need another caller for VFIO, so this patch introduces a helper/wrapper function. If IOMMU is not set, the pci_device_iommu_address_space() function returns the parent's IOMMU skipping the "bus master" address space as otherwise proper emulation would require more effort for no benefit.

2013-08-21loader: store FW CFG ROM files in RAMMichael S. Tsirkin
ROM files that are put in FW CFG are copied to guest ram, by BIOS, but they are not backed by RAM so they don't get migrated. Each time we change two bytes in such a ROM this breaks cross-version migration: since we can migrate after BIOS has read the first byte but before it has read the second one, getting an inconsistent state. Future-proof this by creating, for each such ROM, an MR serving as the backing store. This MR is never mapped into guest memory, but it's registered as RAM so it's migrated with the guest. Naturally, this only helps for -M 1.7 and up, older machine types will still have the cross-version migration bug. Luckily the race window for the problem to trigger is very small, which is also likely why we didn't notice the cross-version migration bug in testing yet. Signed-off-by: Michael S.

2013-08-12virtio: clear signalled_used_valid when switching from dataplaneStefan Hajnoczi
When the dataplane thread stops, its vring.c implementation synchronizes vring state back to virtio.c so we can continue emulating the virtio device. This patch ensures that virtio.c's signalled_used_valid flag is reset so that we do not suppress guest notifications due to stale signalled_used values.

It turns out that some 32 bit windows guests crash if 64 bit PCI hole size is >2G. Limit it to 2G for piix and q35 by default. User may override default 64-bit PCI hole size by using "pci-hole64-size" property.
