2013-10-11Mostly revert "qemu-help: Sort devices by logical functionality"Markus Armbruster1-16/+0
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.

2013-10-10qemu-ga: Add interface to traverse the qmp command list by QmpCommandMark Wu1-2/+4
In the original code, qmp_get_command_list is used to construct a list of all commands' name. To get the information of all qga commands, it traverses the name list and search the command info with its name. So it can cause O(n^2) in the number of commands. This patch adds an interface to traverse the qmp command list by QmpCommand to replace qmp_get_command_list. It can decrease the complexity from O(n^2) to O(n).

2013-10-02util: add socket_set_fast_reuse function which will replace setting SO_REUSEADDRSebastian Ottlik1-0/+1
If a socket is closed it remains in TIME_WAIT state for some time. On operating systems using BSD sockets the endpoint of the socket may not be reused while in this state unless SO_REUSEADDR was set on the socket. On windows on the other hand the default behaviour is to allow reuse (i.e. identical to SO_REUSEADDR on other operating systems) and setting SO_REUSEADDR on a socket allows it to be bound to a endpoint even if the endpoint is already used by another socket independently of the other sockets state. This can even result in undefined behaviour. Many sockets used by QEMU should not block the use of their endpoint after being closed while they are still in TIME_WAIT state. Currently QEMU sets SO_REUSEADDR for such sockets, which can lead to problems on Windows. This patch introduces the function socket_set_fast_reuse that should be used instead of setting SO_REUSEADDR when fast socket reuse is desired and behaves correctly on all operating systems. As a failure of this function can only be caused by bad QEMU internal errors, an assertion handles these situations. The return value is still passed on, to minimize changes in client code and prevent unused variable warnings if NDEBUG is defined.

2013-10-02target-i386: Set model=6 on qemu64 & qemu32 CPU modelsEduardo Habkost1-0/+8
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 Armbruster2-1/+1
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.

2013-09-25qemu: Adjust qemu wakeupLiu, Jinsong1-1/+3
Currently Xen hvm s3 has a bug coming from the difference between qemu-traditioanl and qemu-xen. For qemu-traditional, the way to resume from hvm s3 is via 'xl trigger' command. However, for qemu-xen, the way to resume from hvm s3 inherited from standard qemu, i.e. via QMP, and it doesn't work under Xen. The root cause is, for qemu-xen, 'xl trigger' command didn't reset devices, while QMP didn't unpause hvm domain though they did qemu system reset. We have two qemu patches and one xl patch to fix Xen hvm s3 bug. This patch is the qemu patch 1. It adjusts qemu wakeup so that Xen s3 resume logic (which will be implemented at qemu patch 2) will be notified after qemu system reset.

2013-09-25tcg-ppc: use new return-argument ld/st helpersPaolo Bonzini1-3/+1
These use a 32-bit load-of-immediate to save a mflr+addi+mtlr sequence. Tested with a Windows 98 guest (pretty much the most recent thing I could run on my PPC machine) and kvm-unit-tests's sieve.flat. The speed up for sieve.flat is as high as 10% for qemu-system-i386, 25% (no kidding) for qemu-system-x86_64 on my PowerBook G4.

2013-09-25block: introduce BlockDriver.bdrv_needs_filename to enable some drivers.Benoît Canet1-0/+6
Some drivers will have driver specifics options but no filename. This new bool allow the block layer to treat them correctly. The .bdrv_needs_filename is set in drivers not having .bdrv_parse_filename and not having .bdrv_open. The first exception to this rule will be the quorum driver.

2013-09-20virtio-blk: do not relay a previous driver's WCE configuration to the currentPaolo Bonzini1-0/+1
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.
