2014-06-16libdecnumber: Prepare libdecnumber for QEMU include structureTom Musta
Consistent with other libraries in QEMU, the libdecnumber header files were placed in include/libdecnumber, separate from the C code. This is different from the original libdecnumber source, where they were co-located. Change the libdecnumber source code so that it reflects this split. Specifically, modify directives of the form: #include "xxx.h" to look like: #include "libdecnumber/xxx.h" Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-06-16libdecnumber: Eliminate #include *Symbols.hTom Musta
The various *Symbols.h files were not copied from the original GCC libdecnumber library; they are not necessary for use in QEMU. Remove all instances of #include "*Symbols.h" Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-06-16libdecnumber: Introduce libdecnumber CodeTom Musta
Add files from the libdecnumber decimal floating point library to QEMU. The libdecnumber library was originally part of GCC and contains code that is useful in emulating the PowerPC decimal floating point (DFP) instructions. This particular copy of the source comes from GCC 4.3 and is licensed at GPLv2+. Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>

2014-06-16target-ppc: Remove PVR check from migrationAlexey Kardashevskiy
Currently migration fails if CPU version (PVR register) is different even a bit. This check is performed at the very end of migration when device states are sent. This is too late for management software and we need to provide a way for the user to make sure that migration will succeed if QEMU is started with appropritate command line parameters. This removes the PVR check. This resets PVR to the default value as the existing VMSTATE record for SPR array sends all 1024 registers unconditionally and overwrites the destination PVR. If the user wants some guarantees for migration to succeed, then a CPU name or "host" CPU with a "compat" option (on its way to upsteam) should be used and KVM or TCG is expected to fail on unsupported values at the moment of QEMU start.

Use MSR mnemonics from cpu.h instead of magic numbers for the CPUPPCState.msr_mask initialization. There is one bit in the 401x2 (and subsequent) model that I could not find any documentation for. It is open coded at little endian bit position 20: pcc->msr_mask = (1ull << 20) | (1ull << MSR_KEY) | (1ull << MSR_POW) | (1ull << MSR_CE) | ...

2014-06-16spapr_pci: Fix number of returned vectors in ibm, change-msiAlexey Kardashevskiy
Current guest kernels try allocating as many vectors as the quota is. For example, in the case of virtio-net (which has just 3 vectors) the guest requests 4 vectors (that is the quota in the test) and the existing ibm,change-msi handler returns 4. But before it returns, it calls msix_set_message() in a loop and corrupts memory behind the end of msix_table. This limits the number of vectors returned by ibm,change-msi to the maximum supported by the actual device.

2014-06-16target-ppc: Remove redundant POWER7 declarationsAlexey Kardashevskiy
At the moment there are 3 versions of POWER7 CPUs defined. However we do not emulate these CPUs diffent and it does not make much sense to keep them all. This removes POWER7_v2.0 and POWER7_v2.1 and leaves just one versioned CPU per family which is POWER7_v2.3 with POWER7 alias.

2014-06-16target-ppc: Move alias lookup after class lookupAlexey Kardashevskiy

2014-06-16target-ppc: Create versionless CPU class per family if KVMAlexey Kardashevskiy
At the moment generic version-less CPUs are supported via hardcoded aliases. For example, POWER7 is an alias for POWER7_v2.1. So when QEMU is started with -cpu POWER7, the POWER7_v2.1 class instance is created. This approach works for TCG and KVMs other than HV KVM. HV KVM cannot emulate PVR value so the guest always sees the real PVR. HV KVM will not allow setting PVR other that the host PVR because of that (the kernel patch for it is on its way). So in most cases it is impossible to run QEMU with -cpu POWER7 unless the host PVR is exactly the same as the one from the alias (which is now POWER7_v2.3). It was decided that under HV KVM QEMU should use -cpu host. Using "host" CPU type creates a problem for management tools such as libvirt because they want to know in advance if the destination guest can possibly run on the destination. Since the "host" type is really not a type and will always work with any KVM, there is no way for libvirt to know if the migration will success. This registers additional CPU class derived from the host CPU family. The name for it is taken from @desc field of the CPU family class.

2014-06-16monitor: QEMU Monitor Instruction Disassembly Incorrect for PowerPC LE ModeTom Musta
The monitor support for disassembling instructions does not honor the MSR[LE] bit for PowerPC processors. This change enhances the monitor_disas() routine by supporting a flag bit for Little Endian mode. Bit 16 is used since that bit was used in the analagous guest disassembly routine target_disas(). Also, to be consistent with target_disas(), the disassembler bfd_mach field can be passed in the flags argument.

2014-06-16migration: Increase default max_downtime from 30ms to 300msAlexey Kardashevskiy
The existing timeout is 30ms which on 100MB/s (1Gbit) gives us 3MB/s rate maximum. If we put some load on the guest, it is easy to get page dirtying rate too big so live migration will never complete. In the case of libvirt that means that the guest will be stopped anyway after a timeout specified in the "virsh migrate" command and this normally generates even bigger delay. This changes max_downtime to 300ms which seems to be more reasonable value. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Juan Quintela <quintela@redhat.com>

2014-06-13char: fix avail_connections init in qemu_chr_open_eventfd()David Marchand
When trying to use a ivshmem server with qemu, ivshmem init code tries to create a CharDriverState object for each eventfd retrieved from the server. To create this object, a call to qemu_chr_open_eventfd() is done. Right after this, before adding a frontend, qemu_chr_fe_claim_no_fail() is called. qemu_chr_open_eventfd() does not set avail_connections to 1, so no frontend can be associated because qemu_chr_fe_claim_no_fail() makes qemu stop right away. This problem comes from 456d60692310e7ac25cf822cc1e98192ad636ece "qemu-char: Call fe_claim / fe_release when not using qdev chr properties".
