2013-10-25spapr: Use DeviceClass::fw_name for device tree CPU nodeAndreas Färber
Instead of relying on cpu_model, obtain the device tree node label per CPU. Use DeviceClass::fw_name as source. Whenever DeviceClass::fw_name is unknown, default to "PowerPC,UNKNOWN". As a consequence, spapr_fixup_cpu_dt() can operate on each CPU's fw_name, obsoleting sPAPREnvironment::cpu_model, and spapr_create_fdt_skel() can drop its cpu_model argument.

2013-10-25xics: Implement H_XIRR_XBenjamin Herrenschmidt
This implements H_XIRR_X hypercall in addition to H_XIRR as it is mandatory for PAPR+ and there is no way for the guest to detect whether it is supported or not so just add it. As the Partition Adjunct Option is not supported at the moment, the CPPR parameter of the hypercall is ignored.

2013-10-25xics-kvm: Support for in-kernel XICS interrupt controllerDavid Gibson
Recent (host) kernels support emulating the PAPR defined "XICS" interrupt controller system within KVM. This patch allows qemu to initialize and configure the in-kernel XICS, and keep its state in sync with qemu's XICS state as necessary. This should give considerable performance improvements. e.g. on a simple IPI ping-pong test between hardware threads, using qemu XICS gives us around 5,000 irqs/second, whereas the in-kernel XICS gives us around 70,000 irqs/s on the same hardware configuration.

2013-10-25xics: add cpu_setup callbackAlexey Kardashevskiy

2013-10-25xics: split to xics and xics-commonAlexey Kardashevskiy
The upcoming XICS-KVM support will use bits of emulated XICS code. So this introduces new level of hierarchy - "xics-common" class. Both emulated XICS and XICS-KVM will inherit from it and override class callbacks when required. The new "xics-common" class implements: 1. replaces static "nr_irqs" and "nr_servers" properties with the dynamic ones and adds callbacks to be executed when properties are set. 2. xics_cpu_setup() callback renamed to xics_common_cpu_setup() as it is a common part for both XICS'es 3. xics_reset() renamed to xics_common_reset() for the same reason. The emulated XICS changes: 1. the part of xics_realize() which creates ICPs is moved to the "nr_servers" property callback as realize() is too late to create/initialize devices and instance_init() is too early to create devices as the number of child devices comes via the "nr_servers" property. 2. added ics_initfn() which does a little part of what xics_realize() did.

2013-10-25spapr-rtas: fix h_rtas parameters readingAlexey Kardashevskiy
On the real hardware, RTAS is called in real mode and therefore top 4 bits of the address passed in the call are ignored. So does the patch. This converts h_rtas() to use existing rtas_ld() handlers.

2013-10-14i386: ACPI table generation code from seabiosMichael S. Tsirkin
This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

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.

2013-09-20s390/eventfacility: Fix receive/send masksChristian Borntraeger
Currently we announce interchanged receive/send masks. This did not trigger a bug, since the sclp console has the same masks for send/receive and the Linux guest does not check the sclp mask for simple events like quiesce. With other event users like the sclp line mode console, we will have different send/receive bits. Fix it.

Currently, treat it exactly as a 53C895A. 53C895A is a 53C810 with more capabilities, so this should work. However, this lets us test different code paths on Linux, which don't use lastest features if it detect a 810, or on some OSes which only support 810 and not 895A (like very old Windows NT versions).
