2015-06-26target-mips: add Unified Hosting Interface (UHI) supportLeon Alrae6-26/+408
Add UHI semihosting support for MIPS. QEMU run with "-semihosting" option will alter the behaviour of SDBBP 1 instruction -- UHI operation will be called instead of generating a debug exception. Also tweak Malta's pseudo-bootloader. On CPU reset the $4 register is set to -1 if semihosting arguments are passed to indicate that the UHI operations should be used to obtain input arguments.

2015-06-26hw/mips: Do not clear BEV for MIPS malta kernel loadMatthew Fortune1-1/+1
The BEV flag controls whether the boot exception vector is still in place when starting a kernel. When cleared the exception vector at EBASE (or hard coded address of 0x80000000) is used instead. The early stages of the linux kernel would benefit from BEV still being set to ensure any faults get handled by the boot rom exception handlers. This is a moot point for system qemu as there aren't really any BEV handlers, but there are other good reasons to change this... The UHI (semi-hosting interface) defines special behaviours depending on whether an application starts in an environment with BEV set or cleared. When BEV is set then UHI assumes that a bootloader is relatively dumb and has no advanced exception handling logic. However, when BEV is cleared then UHI assumes that the bootloader has the ability to handle UHI exceptions with its exception handlers and will unwind and forward UHI SYSCALL exceptions to the exception vector that was installed prior to running the application.

2015-06-23util/qemu-sockets: improve ai_flag hints for ipv6 hostsWolfgang Bumiller1-3/+6
*) Do not use AI_ADDRCONFIG on listening sockets, because this flag makes it impossible to explicitly listen on '127.0.0.1' if no global ipv4 address is configured additionally, making this a very uncomfortable option. *) Add AI_V4MAPPED hint for connecting sockets. If your system is globally only connected via ipv6 you often still want to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't also have an ipv6 entry). For example, PVE - unless explicitly asking for insecure mode - uses ipv4 loopback addresses with QEMU for live migrations tunneled over SSH. These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to work with '127.0.0.1'. As for the AI_V4MAPPED flag: glibc uses it by default, and providing non-0 flags removes it. I think it makes sense to use it. I also want to point out that glibc explicitly sidesteps POSIX standards when passing 0 as hints by then assuming both AI_V4MAPPED and AI_ADDRCONFIG (the latter being a rather weird choice IMO), while according to POSIX.1-2001 it should be assumed 0. (glibc considers its choice an improvement.) Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's default flags in turn are disabled again unless explicitly added, which I do with this patch.

Commit 72ac97cdfc added two equivalent versions of decimal128Local.h, one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.

The one in libdecnumber/dpd/ (which is being removed by this patch) is licensed as GPL3.1 (plus gcc runtime exception), which, as far as I know, is not compatible with GPL-2. This file is not used (it is included from include/libdecnumber/dpd/decimal128.h, so version in include/ is used). More, the version in include/ can also be removed, since none of the 3 defines from that file are actually used by the code. Even more, one of the defines from there, decimal128SetSign, is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c, but again, never used. What a mess...

2015-06-23Revert "xen-hvm: increase maxmem before calling xc_domain_populate_physmap"Stefano Stabellini1-24/+0
This reverts commit c1d322e6048796296555dd36fdd102d7fa2f50bf. The original commit fixes a bug when assigning a large number of devices which require option roms to a guest. (One known configuration that needs extra memory is having more than 4 emulated NICs assigned. Three or fewer NICs seems to work without this functionality.) However, by unilaterally increasing maxmem, it introduces two problems. First, now libxl's calculation of the required maxmem during migration is broken -- any guest which exercised this functionality will fail on migration. (Guests which have the default number of devices are not affected.) Secondly, it makes it impossible for a higher-level toolstack or administer to predict how much memory a VM will actually use, making it much more difficult to effectively use all of the memory on a machine.

2015-06-23Fix migration in case of scsi-genericDimitris Aragiorgis2-5/+2
During migration, QEMU uses fsync()/fdatasync() on the open file descriptor for read-write block devices to flush data just before stopping the VM. However, fsync() on a scsi-generic device returns -EINVAL which causes the migration to fail. This patch skips flushing data in case of an SG device, since submitting SCSI commands directly via an SG character device (e.g. /dev/sg0) bypasses the page cache completely, anyway. Note that fsync() not only flushes the page cache but also the disk cache. The scsi-generic device never sends flushes, and for migration it assumes that the same SCSI device is used by the destination host, so it does not issue any SCSI SYNCHRONIZE CACHE (10) command. Finally, remove the bdrv_is_sg() test from iscsi_co_flush() since this is now redundant (we flush the underlying protocol at the end of bdrv_co_flush() which, with this patch, we never reach).
